Building a Production-Ready Azure Lighthouse Deployment Pipeline with EPAC
Recently I worked on an interesting project for an end-to-end Azure Lighthouse implementation. What really stood out to me was the combination of Azure Lighthouse, EPAC, DevOps, and workload identity federation. The deployment model was so compelling that I decided to build and validate the full solution hands-on in my own personal Azure tenants. The result is a detailed article that documents the entire journey, including pipeline design, implementation steps, and the scripts I prepared along the way. You can read the full article here
Intune MAM BYOD: Remove Account message for iOS devices
Hello, I am seeing an issue for Intune MAM BYOD(iOS) users. After a user account password reset, it causes Intune to remove the account configured from mobile applications like MS Outlook, Work, OneDrive, etc. Current Intune Configuration: Done - App Protection Policy Done - Conditional access policy --> Grant --> Requires app protection policy (checked) Users had to re-enrol to access his/her data. Here is the screenshot, Thank you,
Applying DevOps Principles on Lean Infrastructure. Lessons From Scaling to 102K Users.
Hi Azure Community, I'm a Microsoft Certified DevOps Engineer, and I want to share an unusual journey. I have been applying DevOps principles on traditional VPS infrastructure to scale to 102,000 users with 99.2% uptime. Why am I posting this in an Azure community? Because I'm planning migration to Azure in 2026, and I want to understand: What mistakes am I already making that will bite me during migration? THE CURRENT SETUP Platform: Social commerce (West Africa) Users: 102,000 active Monthly events: 2 million Uptime: 99.2% Infrastructure: Single VPS Stack: PHP/Laravel, MySQL, Redis Yes - one VPS. No cloud. No Kubernetes. No microservices. WHY I HAVEN'T USED AZURE YET Honest answer: Budget constraints in emerging market startup ecosystem. At our current scale, fully managed Azure services would significantly increase monthly burn before product-market expansion. The funding we raised needs to last through growth milestones. The trade: I manually optimize what Azure would auto-scale. I debug what Application Insights would catch. I do by hand what Azure Functions would automate. DEVOPS PRACTICES THAT KEPT US RUNNING Even on single-server infrastructure, core DevOps principles still apply: CI/CD Pipeline (GitHub Actions) • 3-5 deployments weekly • Zero-downtime deploys • Automated rollback on health check failures • Feature flags for gradual rollouts Monitoring & Observability • Custom monitoring (would love Application Insights) • Real-time alerting • Performance tracking and slow query detection • Resource usage monitoring Automation • Automated backups • Automated database optimization • Automated image compression • Automated security updates Infrastructure as Code • Configs in Git • Deployment scripts • Environment variables • Documented procedures Testing & Quality • Automated test suite • Pre-deployment health checks • Staging environment • Post-deployment verification KEY OPTIMIZATIONS Async Job Processing • Upload endpoint: 8 seconds → 340ms • 4x capacity increase Database Optimization • Feed loading: 6.4 seconds → 280ms • Strategic caching • Batch processing Image Compression • 3-8MB → 180KB (94% reduction) • Critical for mobile users Caching Strategy • Redis for hot data • Query result caching • Smart invalidation Progressive Enhancement • Server-rendered pages • 2-3 second loads on 4G WHAT I'M WORRIED ABOUT FOR AZURE MIGRATION This is where I need your help: Architecture Decisions • App Service vs Functions + managed services? • MySQL vs Azure SQL? • When does cost/benefit flip for managed services? Cost Management • How do startups manage Azure costs during growth? • Reserved instances vs pay-as-you-go? • Which Azure services are worth the premium? Migration Strategy • Lift-and-shift first, or re-architect immediately? • Zero-downtime migration with 102K active users? • Validation approach before full cutover? Monitoring & DevOps • Application Insights - worth it from day one? • Azure DevOps vs GitHub Actions for Azure deployments? • Operational burden reduction with managed services? Development Workflow • Local development against Azure services? • Cost-effective staging environments? • Testing Azure features without constant bills? MY PLANNED MIGRATION PATH Phase 1: Hybrid (Q1 2026) • Azure CDN for static assets • Azure Blob Storage for images • Application Insights trial • Keep compute on VPS Phase 2: Compute Migration (Q2 2026) • App Service for API • Azure Database for MySQL • Azure Cache for Redis • VPS for background jobs Phase 3: Full Azure (Q3 2026) • Azure Functions for processing • Full managed services • Retire VPS QUESTIONS FOR THIS COMMUNITY Question 1: Am I making migration harder by waiting? Should I have started with Azure at higher cost to avoid technical debt? Question 2: What will break when I migrate? What works on VPS but fails in cloud? What assumptions won't hold? Question 3: How do I validate before cutting over? Parallel infrastructure? Gradual traffic shift? Safe patterns? Question 4: Cost optimization from day one? What to optimize immediately vs later? Common cost mistakes? Question 5: DevOps practices that transfer? What stays the same? What needs rethinking for cloud-native? THE BIGGER QUESTION Have you migrated from self-hosted to Azure? What surprised you? I know my setup isn't best practice by Azure standards. But it's working, and I've learned optimization, monitoring, and DevOps fundamentals in practice. Will those lessons transfer? Or am I building habits that cloud will expose as problematic? Looking forward to insights from folks who've made similar migrations. --- About the Author: Microsoft Certified DevOps Engineer and Azure Developer. CTO at social commerce platform scaling in West Africa. Preparing for phased Azure migration in 2026. P.S. I got the Azure certifications to prepare for this migration. Now I need real-world wisdom from people who've actually done it!

Conditional Access Policy Loop with Edge on BYOD Devices – Need Help!
Body: Hello Tech Community, I’m facing an issue with an Azure AD Conditional Access Policy that seems to be causing a loop when users access Office 365 resources using Microsoft Edge on Windows 11 24H2 BYOD devices. Here’s the scenario: Problem: The policy is titled "Require App Protection Policy for Edge on Windows for All Users when Browser and Non-Compliant-v1.0" and continuously prompts users to switch profiles in Edge. These devices are BYOD and intentionally excluded from full Intune management (non-compliant by design). However, Edge repeatedly requests authentication or profile switching, creating a frustrating experience. Policy Details: Applies to: Windows devices using browsers (primarily Edge). Excludes: Compliant devices or those with trustType = ServerAD. Includes: Office 365 applications. Excludes Groups: Certain groups that should bypass the policy. What I’ve Tried: Verified device compliance status in Azure AD and Intune. Checked Azure AD Sign-In Logs for errors or repetitive authentications. Cleared Edge browser cache and cookies. Ensured Edge is configured to use Windows sign-in information. Adjusted the App Protection Policy settings for Edge. Questions: Could this be an issue with how Edge handles profile authentication in Conditional Access scenarios? How can I ensure that BYOD devices remain excluded from full Intune management but still work seamlessly with this policy? Are there specific adjustments I can make to the Conditional Access or App Protection Policy to avoid these loops? Additional Context: My goal is to secure access using App Protection Policies (MAM) for BYOD scenarios without requiring full device enrollment in Intune. Any insights, suggestions, or similar experiences would be greatly appreciated! Thank you in advance for your help!
