This document discusses strategies for modernizing existing applications, including transforming monolithic applications into microservices, containerizing existing applications, and accelerating new application development. It provides examples of how organizations have benefited from these strategies and highlights tools that can help with the modernization process, such as Docker and Visual Studio 2017 container tools.
![“We love the pristine and predictable environments provided by Windows Server Containers.
Service Fabric brings us a safe and consistent deployment strategy that maximizes uptime. The
marriage of the two in Microsoft Azure gives us unlimited potential.”
– Ralph Feltis, Senior Software Engineer
“With Azure Service Fabric and Windows Containers, we were able to push out [a] new feature
immediately …. That’s a big win for our team and for the airline.”

What's new in containers
- 2. Debugging existing applications “Fixing” existing applications Adding “features” to existing applications Fixing the feature someone else added Building a new application (maybe… if there’s time)
- 3. Maintaining existing applications Re-deploying existing applications Diagnosing issues with existing applications Troubleshooting issues from feature additions Deploying a new application (maybe… if there’s time)
- 4. We can’t throw out every old app. We can’t stop adding features. We can’t stop maintaining old apps. We can make it easier… We can use new tools/code with existing apps…
- 5. TRANSFORM MONOLITHS TO MICROSERVICES New code and transforming existing code CONTAINERIZE EXISTING APPLICATIONS Containerize for portability, efficiency and reliability ACCELERATE NEW APPLICATIONS Agile cloud native app development
- 7. “By upgrading to Windows Server 2016, we were able to ‘lift and shift’ a key security application into Windows Server Containers, gain the flexibility to run it anywhere, and begin to use microservices to refactor aspects of the application to gain needed scalability.” -Stephen Tarmey, Chief Architect
- 9. Reduce infrastructure and operational cost while moving to Azure and modernizing application architecture
