Challenges

Aligned with the vision of being future ready, the client wanted to modernize the application landscape and move the essential applications to cloud native and microservices-based architecture. There was a need to build a modern DevOps environment, implement continuous integration and development pipeline, and host all applications in the pivotal cloud foundry (PCF), which is a multi-cloud platform to run the enterprise apps at scale.

Solution

• Initial discovery phase to understand current applications and its technological details
• Domain-driven approach was followed to break the application into major domains/functionalities to identify microservices that the application can be broken down into.
• Decision tree was considered if applications need to be re-platformed based on whether the existing is not in ASP.NET 4.5 and in MVC
• The following PCF services were identified to be a part of the solution
  • Registry Service
  • Circuit Breaker
  • Config server
  • Redis Cache
• Microservices identified were developed in ASP.NET Core 2.1
• Gitlab was used as the code repository
• Gitlab was also used for CI/CD
• Selenium was used for automated test scripts
• XUnit was used for unit testing
• For authentication, client’s identity server was used for token-based authentication.

All four applications were developed within a short span of 2 months.

Business impact

• The transformed applications are now scalable as the application is broken down into microservices and each service can be scaled up based on usage
• Improved availability of these applications with resilient design pattern implementation with circuit breaker and discovery service
• As all applications are now cloud-native, they align to 15 factor app with all its advantages
• CI/CD pipeline implemented provides all DevOps benefits
• The main critical applications were modernized in a very short span of time and are now future ready

The success of this migration has brought more than a 10% increase in performance. With the foundation/infrastructure as well as processes in place, the client is now looking at migrating more applications using PCF, per their vision.
