From Code to Cloud: Deploy Your Java Apps to Azure in Just 2 Steps!
Microsoft Azure is a great destination for Java applications, and our goal is to help Java developers easily onboard their applications to Azure. We understand that onboarding Java apps to Azure is not only about deploying Java apps but also includes the provisioning of dependent services like databases, messaging services as well as compute services like Azure Kubernetes Service, Azure Application Service, Azure Container Apps, etc. Java developers new to Azure often use either the Azure CLI or the Azure Portal to provision necessary Azure services. This requires learning many different CLI commands, different Portal experiences, and even different infrastructure-as code languages such as Bicep or Terraform. As my colleague Julia Muiruri wrote last week, Azure Developer CLI (AZD) helps developers quickly and efficiently onboard their applications to Azure.Today we are announcing the private preview of a set of new features designed specifically for Java developers. These features are implemented in the AZD CLI and exposed via a Visual Studio Code extension. Register now to try out these features and provide feedback. The new features in AZD simplify Azure onboarding for Java developers by providing a solution that requires only 2 steps to provision and deploy your application to Azure. New Java features in AZD This diagram illustrates the new features in AZD that simplify the developer experience for provisioning and deploying Java applications to Azure: Open your existing Java project in your preferred IDE. If you are using Maven, right click (the 1 st click) on the root pom.xml and choose “generate Azure deployment scripts”. Our tools will generate azure.yaml which declares all the necessary Azure services for your Java project and any connection information your Java application needs to connect to Azure services (such as a database or a messaging service). Next, right click (the 2 nd click) on azure.yaml and select “deploy to Azure”. As a result, all required Azure services will be provisioned automatically and your Java application will be deployed to the appropriate Azure compute service. To achieve this simplicity, AZD offers these key capabilities: An application-centric azure.yaml as the source definition to describe your application. There is no need to use different CLI commands, Bicep or Terraform scripts. Generate azure.yaml from any existing Java repository. You don’t need to write azure.yaml since AZD can analyze your Java project to auto detect resources and bindings between applications and dependent services. AZD will generate the necessary Bicep files from azure.yaml. If you need to view the Bicep files, AZD will synthesize these files for you to review. Getting started Let’s look at how to deploy a simple Spring application to Azure. The sample application is a to-do list management app, composed of three microservices: web, api and email services. When a user adds or updates a to-do item on the web page, the to-do item will be stored into MongoDB by the api service. For to-do items that are “due”, the api service will send messages into Azure Service Bus. These messages will be consumed by email service to send an email to you. This diagram shows the overall architecture and interaction relationship among the three services and their backing Azure services: MongoDB and Azure Service Bus. Putting it all together, to deploy this Spring application to Azure we need to: Provision Azure Cosmos DB for Mongo API. Provision Azure Service Bus. Provision the compute service to run the app, such as Azure Container Apps Deploy all three microservices onto the compute service with correct bindings to the DB or message service. Now let’s see how to do all this with just 2 clicks: Open VS code with this Spring project. Right click on the root pom.xml and choose “Generate Azure deployment Script”. azure.yaml will be generated under the root path with all necessary deployment artifacts declared inside. Right click on the azure.yaml and choose “Package, Provision and Deploy (up)” to trigger the overall provisioning and deployment. After deployment, you’ll see your dedicated resource group in the Azure Portal. In the resource group, you’ll see: Mongo DB: provisioned as Azure Cosmos DB service and running Azure Service Bus: provisioned as Azure Service Bus and running 3 Apps: deployed as Azure Container Apps all running inside a single Azure Container App environment. How to enroll in the private preview Are you a Java developer new to Azure and looking onboard your project or your team’s? Do you need to quickly set up an Azure environment for demonstrations, or aim to reduce development environment maintenance effort as the platform team? Azd might be the ideal solution for you. We encourage you to give it a try today! The new features are now in private preview. If interested, please register by scanning below QR Code or visitinghttps://aka.ms/azd-java-preview directly. We'll contact you within days. Your feedback will help us improve the public preview and GA releases.

What's New in Azure App Service at Ignite 2024
Learn about the GA of sidecar extensibility on Linux and see team members demonstrating the latest tools for AI assisted web application migration and modernization as well as the latest updates to Java JBoss EAP on Azure App Service. Team members will also demonstrate integrating the Phi-3 small language model with a web application via the new sidecar extensibility using existing App Service hardware! Also new for this year’s Ignite, many topics that attendees see in App Service related sessions are also available for hands-on learning across multiple hands-on labs (HoLs). Don’t just watch team members demonstrating concepts on-stage, drop by one of the many HoL sessions and test drive the functionality yourself! Azure App Service team members will also be in attendance at the Expert Meetup area on the third floor in the Hub – drop by and chat if you are attending in-person! Additional demos, presentations and hands-on labs covering App Service are listed at the end of this blog post for easy reference. Sidecar Extensibility GA for Azure App Service on Linux Sidecar extensibility for Azure App Service on Linux is now GA! Linux applications deployed from source-code as well as applications deployed using custom containers can take advantage of sidecar extensibility. Sidecars enable developers to attach additional capabilities like third-party application monitoring providers, in-memory caches, or even local SLM (small language model) support to their applications without having to bake that functionality directly into their applications. Developers can configure up to four sidecar containers per application, with each sidecar being associated with its own container registry and (optional) startup command. Examples of configuring an OpenTelemetry collector sidecar are available in the documentation for both container-based applications and source-code based applications. There are also several recent blog posts demonstrating additional sidecar scenarios. One example walks through using a Redis cache sidecar as an in-memory cache to accelerate data retrieval in a web application (sample code here). Another example demonstrates adding a sidecar containing the Phi-3 SLM to a custom container web application (sample code here). Once the web app is running with the SLM sidecar, Phi-3 processes text prompts directly on the web server without the need to call remote LLMs or host models on scarce GPU hardware. Similar examples for source deployed applications are available in the Ignite 2024 hands on lab demonstrating sidecars. Exercise three walks through attaching an OTel sidecar to a source-code based application, and exercise four shows how to attach a Phi-3 sidecar to a source-code based application. Looking ahead to the future, App Service will be adding “curated sidecars” to the platform to make it easier for developers to integrate common sidecar scenarios. Development is already underway to include options for popular third-party application monitoring providers, Redis cache support, as well as a curated sidecar encapsulating the Phi-3 SLM example mentioned earlier. Stay tuned for these enhancements in the future! If you are attending Microsoft Ignite 2024 in person, drop by the theater session “Modernize your apps with AI without completely rewriting your code” (session code:THR 614) which demonstrates using sidecar extensibility to add Open Telemetry monitoring as well as Phi-3 SLM support to applications on App Service for Linux! .NET 9 GA, JBoss EAP and More Language Updates! With the recent GA of .NET 9 last week developers can deploy applications running .NET 9 GA on both Windows and Linux variants of App Service! Visual Studio, Visual Studio Code, Azure DevOps and GitHub Actions all support building and deploying .NET 9 applications onto App Service. Start a new project using .NET 9 or upgrade your existing .NET applications in-place and take advantage of .NET 9! For JBoss EAP on App Service for Linux, customers will soon be able to bring their existing JBoss licenses with them when moving JBoss EAP workloads onto App Service for Linux. This change will make it easier and more cost effective than ever for JBoss EAP customers to migrate existing workloads to App Service, including JBoss versions 7.3, 7.4 and 8.0! As a quick reminder, last month App Service also announced reduced pricing for JBoss EAP licenses (for net-new workloads) as well as expanded hardware support (both memory-optimized and Free tier are now supported for JBoss EAP applications). App Service is planning to release both Node 22 and Python 3.13 onto App Service for Linux with expected availability in December! Python 3.13 is the latest stable Python release which means developers will be able to leverage this version with confidence given long term support runs into 2029. Node 22 is the latest active LTS release of Node and is a great version for developers to adopt with its long-term support lasting into 2026. A special note for Linux Python developers, App Service now supports “auto-instrumentation” in public preview for Python versions 3.8 through 3.12.This makes it trivial for source-code based Python applications to enable Application Insights monitoring for their applications by simply turning the feature “on” in the Azure Portal. If you ever thought to yourself that it can be a hassle setting up application monitoring and hence find yourself procrastinating, this is the monitoring feature for you! Looking ahead just a few short weeks until December, App Service also plans to release PHP 8.4 for developers on App Service for Linux. This will enable PHP developers to leverage the latest fully supported PHP release with an expected support cycle stretching into 2028. For WordPress customers Azure App Service has added support for managed identities when connecting to MySQL database as well as storage accounts. The platform has also transitioned WordPress from Alpine Linux to Debian, aligning with App Service for Linux to offer a more secure platform. Looking ahead, App Service is excited to introduce some new features by the end of the year, including an App Service plugin for WordPress! This plugin will enable users to manage WordPress integration with Azure Communication Services email, set up Single Sign-On using Microsoft Entra ID, and diagnose performance bottlenecks. Stay tuned for upcoming WordPress announcements! End-to-End TLS & Min TLS Cipher Suite are now GA End-to-end TLS encryption for public multi-tenant App Service is now GA! When E2E TLS is configured, traffic between the App Service frontends and individual workers is secured using a platform supplied TLS certificate. This additional level of security is available for both Windows and Linux sites using Standard SKU and above as well as Isolatedv2 SKUs. You can enable this feature easily in the Azure Portal by going to your resource, clicking the “Configuration” blade and turning the feature “On” as shown below: Configuration of the minimum TLS cipher suite for a web application is also GA! With this feature developers can choose from a pre-determined list of cipher suites. When a minimum cipher suite is selected, the App Service frontends will reject any incoming requests that use a cipher suite weaker than the selected minimum cipher suite. This feature is supported for both Windows and Linux applications using Basic SKU and higher as well as Isolatedv2 SKUs. You configure a minimum TLS cipher suite in the Azure Portal by going to the “Configuration” blade for a website and selecting “Change” for the Minimum Inbound TLS Cipher Suite setting. In the resulting blade (shown below) you can select the minimum cipher suite for your application: To learn more about these and other TLS features on App Service, please refer to the App Service TLS overview. AI-Powered Conversational Diagnostics Building on the Conversational Diagnostics AI-powered tool and the guided decision making path introduced in Diagnostic Workflows, the team has created a new AI-driven natural language-based diagnostics solution for App Service on Linux. The new solution brings together previous functionality to create an experience that comprehends user intent, selects the appropriate Diagnostic Workflow, and keeps users engaged by providing real-time updates and actionable insights through chat. Conversational Diagnostics also provides the grounding data that the generative AI back-end uses to produce recommendations thus empowering users to check the conclusions. The integration of Conversational Diagnostics and Diagnostic Workflows marks a significant advancement in the platform’s diagnostic capabilities. Stay tuned for more updates and experience the transformative power of Generative AI-driven diagnostics firsthand! App Service Migration and Modernization The team just recently introduced new architectural guidance around evolving and modernizing web applications with the Modern Web Application pattern for .NET andJava! This guidance builds on the Reliable Web App pattern for .NET and Java as well as the Azure Migrate application and code assessment tool. With the newly released Modern Web Application guidance, there is a well-documented path for migrating web applications from on-premises/VM deployments using the application and code assessment tool, iterating and evolving web applications with best practices using guidance from the Reliable Web App pattern, and subsequently going deeper on modernization and re-factoring following guidance from the Modern Web Application pattern. Best of all customers can choose to “enter” this journey at any point and progress as far down the modernization path as needed based on their unique business and technical requirements! As a quick recap on the code assessment tool, it is a guided experience inside of Visual Studio with GitHub Copilot providing actionable guidance and feedback on recommended changes needed to migrate applications to a variety of Azure services including Azure App Service. Combined with AI-powered Conversational Diagnostics (mentioned earlier), developers now have AI-guided journeys supporting them from migration all the way through deployment and runtime operation on App Service! Networking and ASE Updates As of November 1, 2024, we are excited to announce that App Service multi-plan subnet join is generally available across all public Azure regions! Multi-plan subnet join eases network management by reducing subnet sprawl, enabling developers to connect multiple app service plans to a single subnet. There is no limit to the number of app service plans that connect to a single subnet. However, developers should keep in mind the number of available IPs since tasks such as changing the SKU for an app service plan will temporarily double the number of IP addresses used in a connected subnet. For more information as well as examples on using multi-plan subnet join see the documentation! App Service also recently announced GA of memory optimized options for Isolatedv2 on App Service Environment v3. The new memory-optimized options range from two virtual cores with 16 GB RAM in I1mv2 (compared to two virtual cores, 8 GB RAM in I1v2) all the way up to 32 virtual cores with 256 GB RAM in I5mv2. The new plansare available in most regions. Check back regularly to see if your preferred region is supported. For more details on the technical specifications of these plans, as well as information on the complete range of tiers and plans forMicrosoft Azure App Service, visit ourpricing page. Using services such as Application Gateway and Azure Front Door with App Service as entry points for client traffic is a common scenario that many of our customers implement. However, when using these services together, there are integration challenges around the default cookie domain for HTTP cookies, including the ARRAffinity cookie used for session affinity. App Service collaborated with the Application Gateway team to introduce a simple solution that addresses the session affinity problem. App Service introduced a new session affinity proxy configuration setting in October which tells App Service to always set the hostname for outbound cookies based on the upstream hostname seen by Application Gateway or Azure Front Door. This simplifies integration with a single-click experience for App Service developers who front-end their websites using one of Azure’s reverse proxies, and it solves the challenge of round-tripping the ArrAffinity cookie when upstream proxies are involved. Looking ahead to early 2025, App Service will shortly be expanding support for IPv6 to include both inbound and outbound connections (currently only inbound connections are supported). The current public preview includes dual-stack support for both IPv4 and IPv6, allowing for a smooth transition and compatibility with existing systems. Read more about the latest status of the IPv6 public preview on App Service here ! Lastly, the new application naming and hostname convention that was rolled out a few months earlier for App Service is now GA for App Service. The platform has also extended this new naming convention to Azure Functions where it is now available in public preview for newly created functions. To learn more about the new naming convention and the protection it provides against subdomain takeover take a look at the introductory blog post about the unique default hostname feature. Upcoming Availability Zone Improvements New Availability Zone features are currently rolling out that will make zone redundant App Service deployments more cost efficient and simpler to manage in early 2025! The platform will be changing the minimum requirement for enabling Availability Zones to two instances instead of three, while still maintaining a 99.99% SLA. Many existing app service plans with two or more instances will also automatically become capable of supporting Availability Zones without requiring additional setup. Additionally, the zone redundant setting will be mutable throughout the life of an app service plan. This upcoming improvement will allow customers on Premium V2, Premium V3, or Isolated V2 plans, to toggle zone redundancy on or off as needed. Customers will also gain enhanced visibility into Availability Zone information, including physical zone placement and counts. As a sneak peek into the future, the screenshot below shows what the new experience will look like in the Azure Portal: Stay tuned for Availability Zone updates coming to App Service in early 2025!
