Search Less, Build More: Inner Sourcing with GitHub CoPilot and ADO MCP Server
Developers burn cycles context‑switching: opening five repos to find a logging example, searching a wiki for a data masking rule, scrolling chat history for the latest pipeline pattern. Organisations that I speak to are often on the path of transformational platform engineering projects but always have the fear or doubt of "what if my engineers don't use these resources". While projects like Backstage still play a pivotal role in inner sourcing and discoverability I also empathise with developers who would argue "How would I even know in the first place, which modules have or haven't been created for reuse". In this blog we explore how we can ensure organisational standards and developer satisfaction without any heavy lifting on either side, no custom model training, no rewriting or relocating of repositories and no stagnant local data. Using GitHub CoPilot + Azure DevOps MCP server (with the free `code_search` extension) we turn the IDE into an organizational knowledge interface. Instead of guessing or re‑implementing, engineers can start scaffolding projects or solving issues as they would normally (hopefully using CoPilot) and without extra prompting. GitHub CoPilot can lean into organisational standards and ensure recommendations are made with code snippets directly generated from existing examples. What Is the Azure DevOps MCP Server + code_search Extension? MCP (Model Context Protocol) is an open standard that lets agents (like GitHub Copilot) pull in structured, on-demand context from external systems. MCP servers contain natural language explanations of the tools that the agent can utilise allowing dynamic decision making of when to implement certain toolsets over others. The Azure DevOps MCP Server is the ADO Product Team's implementation of that standard. It exposes your ADO environment in a way CoPilot can consume. Out of the box it gives you access to: Projects – list and navigate across projects in your organization. Repositories – browse repos, branches, and files. Work items – surface user stories, bugs, or acceptance criteria. Wiki's – pull policies, standards, and documentation. This means CoPilot can ground its answers in live ADO content, instead of hallucinating or relying only on what’s in the current editor window. The ADO server runs locally from your own machine to ensure that all sensitive project information remains within your secure network boundary. This also means that existing permissions on ADO objects such as Projects or Repositories are respected. Wiki search tooling available out of the box with ADO MCP server is very useful however if I am honest I have seen these wiki's go unused with documentation being stored elsewhere either inside the repository or in a project management tool. This means any tool that needs to implement code requires the ability to accurately search the code stored in the repositories themself. That is where the code_search extension enablement in ADO is so important. Most organisations have this enabled already however it is worth noting that this pre-requisite is the real unlock of cross-repo search. This allows for CoPilot to: Query for symbols, snippets, or keywords across all repos. Retrieve usage examples from code, not just docs. Locate standards (like logging wrappers or retry policies) wherever they live. Back every recommendation with specific source lines. In short: MCP connects CoPilot to Azure DevOps. code_search makes that connection powerful by turning it into a discovery engine. What is the relevance of CoPilot Instructions? One of the less obvious but most powerful features of GitHub CoPilot is its ability to follow instructions files. CoPilot automatically looks for these files and uses them as a “playbook” for how it should behave. There are different types of instructions you can provide: Organisational instructions – apply across your entire workspace, regardless of which repo you’re in. Repo-specific instructions – scoped to a particular repository, useful when one project has unique standards or patterns. Personal instructions – smaller overrides layered on top of global rules when a local exception applies. (Stored in .github/copilot-instructions.md) In this solution, I’m using a single personal instructions file. It tells CoPilot: When to search (e.g., always query repos and wikis before answering a standards question). Where to look (Azure DevOps repos, wikis, and with code_search, the code itself). How to answer (responses must cite the repo/file/line or wiki page; if no source is found, say so). How to resolve conflicts (prefer dated wiki entries over older README fragments). As a small example, a section of a CoPilot instruction file could look like this: # GitHub Copilot Instructions for Azure DevOps MCP Integration This project uses Azure DevOps with MCP server integration to provide organizational context awareness. Always check to see if the Azure DevOps MCP server has a tool relevant to the user's request. ## Core Principles ### 1. Azure DevOps Integration - **Always prioritize Azure DevOps MCP tools** when users ask about: - Work items, stories, bugs, tasks - Pull requests and code reviews - Build pipelines and deployments - Repository operations and branch management - Wiki pages and documentation - Test plans and test cases - Project and team information ### 2. Organizational Context Awareness - Before suggesting solutions, **check existing organizational patterns** by: - Searching code across repositories for similar implementations - Referencing established coding standards and frameworks - Looking for existing shared libraries and utilities - Checking architectural decision records (ADRs) in wikis ### 3. Cross-Repository Intelligence - When providing code suggestions: - **Search for existing patterns** in other repositories first - **Reference shared libraries** and common utilities - **Maintain consistency** with organizational standards - **Suggest reusable components** when appropriate ## Tool Usage Guidelines ### Work Items and Project Management When users mention bugs, features, tasks, or project planning: ``` ✅ Use: wit_my_work_items, wit_create_work_item, wit_update_work_item ✅ Use: wit_list_backlogs, wit_get_work_items_for_iteration ✅ Use: work_list_team_iterations, core_list_projects The result... To test this I created 3 ADO Projects each with between 1-2 repositories. The repositories were light with only ReadMe's inside containing descriptions of the "repo" and some code snippets examples for usage. I have then created a brand-new workspace with no context apart from a CoPilot instructions document (which could be part of a repo scaffold or organisation wide) which tells CoPilot to search code and the wikis across all ADO projects in my demo environment. It returns guidance and standards from all available repo's and starts to use it to formulate its response. In the screenshot I have highlighted some key parts with red boxes. The first being a section of the readme that CoPilot has identified in its response, that part also highlighted within CoPilot chat response. I have highlighted the rather generic prompt I used to get this response at the bottom of that window too. Above I have highlighted CoPilot using the MCP server tooling searching through projects, repo's and code. Finally the largest box highlights the instructions given to CoPilot on how to search and how easily these could be optimised or changed depending on the requirements and organisational coding standards. How did I implement this? Implementation is actually incredibly simple. As mentioned I created multiple projects and repositories within my ADO Organisation in order to test cross-project & cross-repo discovery. I then did the following: Enable code_search - in your Azure DevOps organization (Marketplace → install extension). Login to Azure - Use the AZ CLI to authenticate to Azure with "az login". Create vscode/mcp.json file - Snippet is provided below, the organisation name should be changed to your organisations name. Start and enable your MCP server - In the mcp.json file you should see a "Start" button. Using the snippet below you will be prompted to add your organisation name. Ensure your CoPilot agent has access to the server under "tools" too. View this setup guide for full setup instructions (azure-devops-mcp/docs/GETTINGSTARTED.md at main · microsoft/azure-devops-mcp) Create a CoPilot Instructions file - with a search-first directive. I have inserted the full version used in this demo at the bottom of the article. Experiment with Prompts – Start generic (“How do we secure APIs?”). Review the output and tools used and then tailor your instructions. Considerations While this is a great approach I do still have some considerations when going to production. Latency - Using MCP tooling on every request will add some latency to developer requests. We can look at optimizing usage through copilot instructions to better identify when CoPilot should or shouldn't use the ADO MCP server. Complex Projects and Repositories - While I have demonstrated cross project and cross repository retrieval my demo environment does not truly simulate an enterprise ADO environment. Performance should be tested and closely monitored as organisational complexity increases. Public Preview - The ADO MCP server is moving quickly but is currently still public preview. We have demonstrated in this article how quickly we can make our Azure DevOps content discoverable. While their are considerations moving forward this showcases a direction towards agentic inner sourcing. Feel free to comment below how you think this approach could be extended or augmented for other use cases! Resources MCP Server Config (/.vscode/mcp.json) { "inputs": [ { "id": "ado_org", "type": "promptString", "description": "Azure DevOps organization name (e.g. 'contoso')" } ], "servers": { "ado": { "type": "stdio", "command": "npx", "args": ["-y", "@azure-devops/mcp", "${input:ado_org}"] } } } CoPilot Instructions (/.github/copilot-instructions.md) # GitHub Copilot Instructions for Azure DevOps MCP Integration This project uses Azure DevOps with MCP server integration to provide organizational context awareness.

Unlocking Application Modernisation with GitHub Copilot
AI-driven modernisation is unlocking new opportunities you may not have even considered yet. It's also allowing organisations to re-evaluate previously discarded modernisation attempts that were considered too hard, complex or simply didn't have the skills or time to do. During Microsoft Build 2025, we were introduced to the concept of Agentic AI modernisation and this post from Ikenna Okeke does a great job of summarising the topic - Reimagining App Modernisation for the Era of AI | Microsoft Community Hub. This blog post however, explores the modernisation opportunities that you may not even have thought of yet, the business benefits, how to start preparing your organisation, empowering your teams, and identifying where GitHub Copilot can help. I’ve spent the last 8 months working with customers exploring usage of GitHub Copilot, and want to share what my team members and I have discovered in terms of new opportunities to modernise, transform your applications, bringing some fun back into those migrations! Let’s delve into how GitHub Copilot is helping teams update old systems, move processes to the cloud, and achieve results faster than ever before. Background: The Modernisation Challenge (Then vs Now) Modernising legacy software has always been hard. In the past, teams faced steep challenges: brittle codebases full of technical debt, outdated languages (think decades-old COBOL or VB6), sparse documentation, and original developers long gone. Integrating old systems with modern cloud services often requiring specialised skills that were in short supply – for example, check out this fantastic post from Arvi LiVigni (@arilivigni ) which talks about migrating from COBOL “the number of developers who can read and write COBOL isn’t what it used to be,” making those systems much harder to update". Common pain points included compatibility issues, data migrations, high costs, security vulnerabilities, and the constant risk that any change could break critical business functions. It’s no wonder many modernisation projects stalled or were “put off” due to their complexity and risk. So, what’s different now (circa 2025) compared to two years ago? In a word: Intelligent AI assistance. Tools like GitHub Copilot have emerged as AI pair programmers that dramatically lower the barriers to modernisation. Arvi’s post talks about how only a couple of years ago, developers had to comb through documentation and Stack Overflow for clues when deciphering old code or upgrading frameworks. Today, GitHub Copilot can act like an expert co-developer inside your IDE, ready to explain mysterious code, suggest updates, and even rewrite legacy code in modern languages. This means less time fighting old code and more time implementing improvements. As Arvi says “nine times out of 10 it gives me the right answer… That speed – and not having to break out of my flow – is really what’s so impactful.” In short, AI coding assistants have evolved from novel experiments to indispensable tools, reimagining how we approach software updates and cloud adoption. I’d also add from my own experience – the models we were using 12 months ago have already been superseded by far superior models with ability to ingest larger context and tackle even further complexity. It's easier to experiment, and fail, bringing more robust outcomes – with such speed to create those proof of concepts, experimentation and failing faster, this has also unlocked the ability to test out multiple hypothesis’ and get you to the most confident outcome in a much shorter space of time. Modernisation is easier now because AI reduces the heavy lifting. Instead of reading the 10,000-line legacy program alone, a developer can ask Copilot to explain what the code does or even propose a refactored version. Rather than manually researching how to replace an outdated library, they can get instant recommendations for modern equivalents. These advancements mean that tasks which once took weeks or months can now be done in days or hours – with more confidence and less drudgery - more fun! The following sections will dive into specific opportunities unlocked by GitHub Copilot across the modernisation journey which you may not even have thought of. Modernisation Opportunities Unlocked by Copilot Modernising an application isn’t just about updating code – it involves bringing everyone and everything up to speed with cloud-era practices. Below are several scenarios and how GitHub Copilot adds value, with the specific benefits highlighted: 1. AI-Assisted Legacy Code Refactoring and Upgrades Instant Code Comprehension: GitHub Copilot can explain complex legacy code in plain English, helping developers quickly understand decades-old logic without scouring scarce documentation. For example, you can highlight a cryptic COBOL or C++ function and ask Copilot to describe what it does – an invaluable first step before making any changes. This saves hours and reduces errors when starting a modernisation effort. Automated Refactoring Suggestions: The AI suggests modern replacements for outdated patterns and APIs, and can even translate code between languages. For instance, Copilot can help convert a COBOL program into JavaScript or C# by recognising equivalent constructs. It also uses transformation tools (like OpenRewrite for Java/.NET) to systematically apply code updates – e.g. replacing all legacy HTTP calls with a modern library in one sweep. Developers remain in control, but GitHub Copilot handles the tedious bulk edits. Bulk Code Upgrades with AI: GitHub Copilot’s App Modernisation capabilities can analyse an entire codebase and generate a detailed upgrade plan, then execute many of the code changes automatically. It can upgrade framework versions (say from .NET Framework 4.x to .NET 6, or Java 8 to Java 17) by applying known fix patterns and even fixing compilation errors after the upgrade. Teams can finally tackle those hundreds of thousand-line enterprise applications – a task that could take multiple years with GitHub Copilot handling the repetitive changes. Technical Debt Reduction: By cleaning up old code and enforcing modern best practices, GitHub Copilot helps chip away at years of technical debt. The modernised codebase is more maintainable and stable, which lowers the long-term risk hanging over critical business systems. Notably, the tool can even scan for known security vulnerabilities during refactoring as it updates your code. In short, each legacy component refreshed with GitHub Copilot comes out safer and easier to work on, instead of remaining a brittle black box. 2. Accelerating Cloud Migration and Azure Modernisation Guided Azure Migration Planning: GitHub Copilot can assess a legacy application’s cloud readiness and recommend target Azure services for each component. For instance, it might suggest migrating an on-premises database to Azure SQL, moving file storage to Azure Blob Storage, and converting background jobs to Azure Functions. This provides a clear blueprint to confidently move an app from servers to Azure PaaS. One-Click Cloud Transformations: GitHub Copilot comes with predefined migration tasksthat automate the code changes required for cloud adoption. With one click, you can have the AI apply dozens of modifications across your codebase. For example: File storage: Replace local file read/writes with Azure Blob Storage SDK calls. Email/Comms: Swap out SMTP email code for Azure Communication Services or SendGrid. Identity: Migrate authentication from Windows AD to Azure AD (Entra ID) libraries. Configuration: Remove hard-coded configurations and use Azure App Configuration or Key Vault for secrets. GitHub Copilot performs these transformations consistently, following best practices (like using connection strings from Azure settings). After applying the changes, it even fixes any compile errors automatically, so you’re not left with broken builds. What used to require reading countless Azure migration guides is now handled in minutes. Automated Validation & Deployment: Modernisation doesn’t stop at code changes. GitHub Copilot can also generate unit tests to validate that the application still behaves correctly after the migration. It helps ensure that your modernised, cloud-ready app passes all its checks before going live. When you’re ready to deploy, GitHub Copilot can produce the necessary Infrastructure-as-Code templates (e.g. Azure Resource Manager Bicep files or Terraform configs) and even set up CI/CD pipeline scripts for you. In other words, the AI can configure the Azure environment and deployment process end-to-end. This dramatically reduces manual effort and error, getting your app to the cloud faster and with greater confidence. Integrations: GitHub Copilot also helps tackle larger migration scenarios that were previously considered too complex. For example, many enterprises want to retire expensive proprietary integration platforms like MuleSoft or Apigee and use Azure-native services instead, but rewriting hundreds of integration workflows was daunting. Now, GitHub Copilot can assist in translating those workflows: for instance, converting an Apigee API proxy into an Azure API Management policy, or a MuleSoft integration into an Azure Logic App. Multi-Cloud Migrations: if you plan to consolidate from other clouds into Azure, GitHub Copilot can suggest equivalent Azure services and SDK calls to replace AWS or GCP-specific code. These AI-assisted conversions significantly cut down the time needed to reimplement functionality on Azure. The business impact can be substantial. By lowering the effort of such migrations, GitHub Copilot makes it feasible to pursue opportunities that deliver big cost savings and simplification. 3. Boosting Developer Productivity and Quality Instant Unit Tests (TDD Made Easy): Writing tests for old code can be tedious, but GitHub Copilot can generate unit test cases on the fly. Developers can highlight an existing function and ask Copilot to create tests; it will produce meaningful test methods covering typical and edge scenarios. This makes it practical to apply test-driven development practices even to legacy systems – you can quickly build a safety net of tests before refactoring. By catching bugs early through these AI-generated tests, teams gain confidence to modernise code without breaking things. It essentially injects quality into the process from the start, which is crucial for successful modernisation. DevOps Automation: GitHub Copilot helps modernise your build and deployment process as well. It can draft CI/CD pipeline configurations, Dockerfiles, Kubernetes manifests, and other DevOps scripts by leveraging its knowledge of common patterns. For example, when setting up a GitHub Actions workflow to deploy your app, GitHub Copilot will autocomplete significant parts (like build steps, test runs, deployment jobs) based on the project structure. This not only saves time but also ensures best practices (proper caching, dependency installation, etc.) are followed by default. Microsoft even provides an extension where you can describe your Azure infrastructure needs in plain language and have GitHub Copilot generate the corresponding templates and pipeline YAML. By automating these pieces, teams can move to cloud-based, automated deployments much faster. Behaviour-Driven Development Support: Teams practicing BDD write human-readable scenarios (e.g. using Gherkin syntax) describing application behaviour. GitHub Copilot’s AI is adept at interpreting such descriptions and suggesting step definition code or test implementations to match. For instance, given a scenario “When a user with no items checks out, then an error message is shown,” GitHub Copilot can draft the code for that condition or the test steps required. This helps bridge the gap between non-technical specifications and actual code. It makes BDD more efficient and accessible, because even if team members aren’t strong coders, the AI can translate their intent into working code that developers can refine. Quality and Consistency: By using AI to handle boilerplate and repetitive tasks, developers can focus more on high-value improvements. GitHub Copilot’s suggestions are based on a vast corpus of code, which often means it surfaces well-structured, idiomatic patterns. Starting from these suggestions, developers are less likely to introduce errors or reinvent the wheel, which leads to more consistent code quality across the project. The AI also often reminds you of edge cases (for example, suggesting input validation or error handling code that might be missed), contributing to a more robust application. In practice, many teams find that adopting GitHub Copilot results in fewer bugs and quicker code reviews, as the code is cleaner on the first pass. It’s like having an extra set of eyes on every pull request, ensuring standards are met. Business Benefits of AI-Powered Modernisation Bringing together the technical advantages above, what’s the payoff for the business and stakeholders? Modernising with GitHub Copilot can yield multiple tangible and intangible benefits: Accelerated Time-to-Market: Modernisation projects that might have taken a year can potentially be completed in a few months, or an upgrade that took weeks can be done in days. This speed means you can deliver new features to customers sooner and respond faster to market changes. It also reduces downtime or disruption since migrations happen more swiftly. Cost Savings: By automating repetitive work and reducing the effort required from highly paid senior engineers, GitHub Copilot can trim development costs. Faster project completion also means lower overall project cost. Additionally, running modernised apps on cloud infrastructure (with updated code) often lowers operational costs due to more efficient resource usage and easier maintenance. There’s also an opportunity cost benefit: developers freed up by Copilot can work on other value-adding projects in parallel. Improved Quality & Reliability: GitHub Copilot’s contributions to testing, bug-fixing, and even security (like patching known vulnerabilities during upgrades) result in more robust applications. Modernised systems have fewer outages and security incidents than shaky legacy ones. Stakeholders will appreciate that with GitHub Copilot, modernisation doesn’t mean “trading one set of bugs for another” – instead, you can increase quality as you modernise (GitHub’s research noted higher code quality when using Copilot, as developers are less likely to introduce errors or skip tests). Business Agility: A modernised application (especially one refactored for cloud) is typically more scalable and adaptable. New integrations or features can be added much faster once the platform is up-to-date. GitHub Copilot helps clear the modernisation hurdle, after which the business can innovate on a solid, flexible foundation (for example, once a monolith is broken into microservices or moved to Azure PaaS, you can iterate on it much faster in the future). AI-assisted modernisation thus unlocks future opportunities (like easier expansion, integrations, AI features, etc.) that were impractical on the legacy stack. Employee Satisfaction and Innovation: Developer happiness is a subtle but important benefit. When tedious work is handled by AI, developers can spend more time on creative tasks – designing new features, improving user experience, exploring new technologies. This can foster a culture of innovation. Moreover, being seen as a company that leverages modern tools (like AI Co-pilots) helps attract and retain top tech talent. Teams that successfully modernise critical systems with Copilot will gain confidence to tackle other ambitious projects, creating a positive feedback loop of improvement. To sum up, GitHub Copilot acts as a force-multiplier for application modernisation. It enables organisations to do more with less: convert legacy “boat anchors” into modern, cloud-enabled assets rapidly, while improving quality and developer morale. This aligns IT goals with business goals – faster delivery, greater efficiency, and readiness for the future. Call to Action: Embrace the Future of Modernisation GitHub Copilot has proven to be a catalyst for transforming how we approach legacy systems and cloud adoption. If you’re excited about the possibilities, here are next steps and what to watch for: Start Experimenting: If you haven’t already, try GitHub Copilot on a sample of your code. Use Copilot or Copilot Chat to explain a piece of old code or generate a unit test. Seeing it in action on your own project can build confidence and spark ideas for where to apply it. Identify a Pilot Project: Look at your application portfolio for a candidate that’s ripe for modernisation – maybe a small legacy service that could be moved to Azure, or a module that needs a refactor. Use GitHub Copilot to assess and estimate the effort. Often, you’ll find tasks once deemed “too hard” might now be feasible. Early successes will help win support for larger initiatives.

To learn more, visit: https://aka.ms/fnonacav2Azure at KubeCon India 2025 | Hyderabad, India – 6-7 August 2025
Welcome to KubeCon + CloudNativeCon India 2025! We’re thrilled to join this year’s event in Hyderabad as a Gold sponsor, where we’ll be highlighting the newest innovations in Azure and Azure Kubernetes Service (AKS) while connecting with India’s dynamic cloud-native community. We’re excited to share some powerful new AKS capabilities that bring AI innovation to the forefront, strengthen security and networking, and make it easier than ever to scale and streamline operations. Innovate with AI AI is increasingly central to modern applications and competitive innovation, and AKS is evolving to support intelligent agents more natively. The AKS Model Context Protocol (MCP) server, now in public preview, introduces a unified interface that abstracts Kubernetes and Azure APIs, allowing AI agents to manage clusters more easily across environments. This simplifies diagnostics and operations—even across multiple clusters—and is fully open-source, making it easier to integrate AI-driven tools into Kubernetes workflows. Enhance networking capabilities Networking is foundational to application performance and security. This wave of AKS improvements delivers more control, simplicity, and scalability in networking: Traffic between AKS services can now be filtered by HTTP methods, paths, and hostnames using Layer-7 network policies, enabling precise control and stronger zero-trust security. Built-in HTTP proxy management simplifies cluster-wide proxy configuration and allows easy disabling of proxies, reducing misconfigurations while preserving future settings. Private AKS clusters can be accessed securely through Azure Bastion integration, eliminating the need for VPNs or public endpoints by tunneling directly with kubectl. DNS performance and resilience are improved with LocalDNS for AKS, which enables pods to resolve names even during upstream DNS outages, with no changes to workloads. Outbound traffic from AKS can now use static egress IP prefixes, ensuring predictable IPs for compliance and smoother integration with external systems. Cluster scalability is enhanced by supporting multiple Standard Load Balancers, allowing traffic isolation and avoiding rule limits by assigning SLBs to specific node pools or services. Network troubleshooting is streamlined with Azure Virtual Network Verifier, which runs connectivity tests from AKS to external endpoints and identifies misconfigured firewalls or routes. Strengthen security posture Security remains a foundational priority for Kubernetes environments, especially as workloads scale and diversify. The following enhancements strengthen protection for data, infrastructure, and applications running in AKS—addressing key concerns around isolation, encryption, and visibility. Confidential VMs for Azure Linux enable containers to run on hardware-encrypted, isolated VMs using AMD SEV-SNP, providing data-in-use protection for sensitive workloads without requiring code changes. Confidential VMs for Ubuntu 24.04 combine AKS’s managed Kubernetes with memory encryption and VM-level isolation, offering enhanced security for Linux containers in Ubuntu-based clusters. Encryption in transit for NFS secures data between AKS pods and Azure Files NFS volumes using TLS 1.3, protecting sensitive information without modifying applications. Web Application Firewall for Containers adds OWASP rule-based protection to containerized web apps via Azure Application Gateway, blocking common exploits without separate WAF appliances. The AKS Security Dashboard in Azure Portal centralizes visibility into vulnerabilities, misconfigurations, compliance gaps, and runtime threats, simplifying cluster security management through Defender for Cloud. Simplify and scale operations To streamline operations at scale, AKS is introducing new capabilities that automate resource provisioning, enforce deployment best practices, and simplify multi-tenant management—making it easier to maintain performance and consistency across complex environments. Node Auto-Provisioning improves resource efficiency by automatically adding and removing standalone nodes based on pod demand, eliminating the need for pre-created node pools during traffic spikes. Deployment Safeguards help prevent misconfigurations by validating Kubernetes manifests against best practices and optionally enforcing corrections to reduce instability and security risks. Managed Namespaces streamline multi-tenant cluster operations by providing a unified view of accessible namespaces across AKS clusters, along with quick access credentials via CLI, API, or Portal. Maximize performance and visibility To enhance performance and observability in large-scale environments, AKS is also rolling out infrastructure-level upgrades that improve monitoring capacity and control plane efficiency. Prometheus quotas in Azure Monitor can now be raised to 20 million samples per minute or active time series, ensuring full metric coverage for massive AKS deployments. Control plane performance has been improved with a backported Kubernetes enhancement (KEP-5116), reducing API server memory usage by ~10× during large listings and enabling faster kubectl responses with lower risk of OOM issues in AKS versions 1.31.9 and above.

Azure Container Apps is a fully managed serverless container service that enables you to deploy and run applications without having to manage the infrastructure. The Azure Container Apps team has made improvements recently to the load balancing algorithm and scaling behavior to better align with customer expectations to meet their performance needs.
Running Self-hosted APIM Gateways in Azure Container Apps with VNet Integration
With Azure Container Apps we can run containerized applications, completely serverless. The platform itself handles all the orchestration needed to dynamically scale based on your set triggers (such as KEDA) and even scale-to-zero! I have been working a lot with customers recently on using Azure API Management (APIM) and the topic of how we can leverage Azure APIM to manage our internal APIs without having to expose a public IP and stay within compliance from a security standpoint, which leads to the use of a Self-Hosted Gateway. This offers a managed gateway deployed within their network, allowing a unified approach in managing their APIs while keeping all API communication in-network. The self-hosted gateway is deployed as a container and in this article, we will go through how to provision a self-hosted gateway on Azure Container Apps specifically. I assume there is already an Azure APIM instance provisioned and will dive into creating and configuring the self-hosted gateway on ACA. Prerequisites As mentioned, ensure you have an existing Azure API Management instance. We will be using the Azure CLI to configure the container apps in this walkthrough. To run the commands, you need to have the Azure CLI installed on your local machine and ensure you have the necessary permissions in your Azure subscription. Retrieve Gateway Deployment Settings from APIM First, we need to get the details for our gateway from APIM. Head over to the Azure portal and navigate to your API Management instance. - In the left menu, under Deployment and infrastructure, select Gateways. - Here, you'll find the gateway resource you provisioned. Click on it and go to Deployment. - You'll need to copy the Gateway Token and Configuration endpoint values. (these tell the self-hosted gateway which APIM instance and Gateway to register under) Create a Container Apps Environment Next, we need to create a Container Apps environment. This is where we will create the container app in which our self-hosted gateway will be hosted. Using Azure CLI: Create our VNet and Subnet for our ACA Environment As we want access to our internal APIs, when we create the container apps environment, we need to have the VNet created with a subnet available. Note: If we’re using Workload Profiles (we will in this walkthrough), then we need to delegate the subnet to Microsoft.App/environments. # Create the vnet az network vnet create --resource-group rgContosoDemo \ --name vnet-contoso-demo \ --location centralUS \ --address-prefix 10.0.0.0/16 # Create the subnet az network vnet subnet create --resource-group rgContosoDemo \ --vnet-name vnet-contoso-demo \ --name infrastructure-subnet \ --address-prefixes 10.0.0.0/23 # If you are using a workload profile (we are for this walkthrough) then delegate the subnet az network vnet subnet update --resource-group rgContosoDemo \ --vnet-name vnet-contoso-demo \ --name infrastructure-subnet \ --delegations Microsoft.App/environments Create the Container App Environment in out VNet az containerapp env create --name aca-contoso-env \ --resource-group rgContosoDemo \ --location centralUS \ --enable-workload-profiles Deploy the Self-Hosted Gateway to a Container App Creating the environment takes about 10 minutes and once complete, then comes the fun part—deploying the self-hosted gateway container image to a container app. Using Azure CLI: Create the Container App: az containerapp create --name aca-apim-demo-gateway \ --resource-group rgContosoDemo \ --environment aca-contoso-env \ --workload-profile-name "Consumption" \ --image "mcr.microsoft.com/azure-api-management/gateway:2.5.0" \ --target-port 8080 \ --ingress 'external' \ ---env-vars "config.service.endpoint"="<YOUR_ENDPOINT>" "config.service.auth"="<YOUR_TOKEN>" "net.server.http.forwarded.proto.enabled"="true" Here, you'll replace <YOUR_ENDPOINT> and <YOUR_TOKEN> with the values you copied earlier. Configure Ingress for the Container App: az containerapp ingress enable --name aca-apim-demo-gateway --resource-group rgContosoDemo --type external --target-port 8080 This command ensures that your container app is accessible externally. Verify the Deployment Finally, let's make sure everything is running smoothly. Navigate to the Azure portal and go to your Container Apps environment. Select the container app you created (aca-apim-demo-gateway) and navigate to Replicas to verify that it's running. You can use the status endpoint of the self-hosted gateway to determine if your gateway is running as well: curl -i https://aca-apim-demo-gateway.sillytreats-abcd1234.centralus.azurecontainerapps.io/status-012345678990abcdef Verify Gateway Health in APIM You can navigate in the Azure Portal to APIM and verify the gateway is showing up as healthy. Navigate to Deployment and Infrastructure, select Gateways then choose your Gateway. On the Overview page you’ll see the status of your gateway deployment. And that’s it! You've successfully deployed an Azure APIM self-hosted gateway in Azure Container Apps with VNet integration allowing access to your internal APIs with easy management from the APIM portal in Azure. This setup allows you to manage your APIs efficiently while leveraging the scalability and flexibility of Azure Container Apps. If you have any questions or need further assistance, feel free to ask. How are you feeling about this setup? Does it make sense, or is there anything you'd like to dive deeper into?
