A Practical Three-step Approach to Migrating to Microservices

Our client was looking for a solution to upgrade their monolith architecture. We recommended a microservices approach to focus on the business functionality allowing self-contained units to represent a module’s end-to-end functionality. One application constitutes one or many modules, whereas, a set of microservices assembled represents an application.

To migrate to microservices, a practical three-step approach:

Componentize: From your already existing applications, select a component and create a microservices implementation on a pilot basis.

Collaborate: All stakeholders, programmers, and developers on the team should know about the techniques and lessons learned from the Pilot in Stage One. This keeps them updated with new processes and initiatives.

Connect: Complete the application and connect to users in a real-world scenario.

The Challenge:

As requests for system changes continued to grow, so did the volume of support requests and development man-hours. The demand to conduct development was becoming increasingly slow, continuous deployment became difficult, and scaling the application was costly.

The Solution:

We used our three-step approach to migrating their application to microservices that would enable them to deploy updates and new applications more rapidly and frequently. Our design used open-source products for cost efficiency. This allowed their developers once implemented to:

  • Identify and diagnose issues quickly
  • Provide the ability to leverage cloud architecture to control costs
  • Provide flexible analytics and application performance
  • Eliminate any long-term commitment to a technology stack making it easier to adopt new technology.

The Results:

After implementing the microservices framework developed by Charter Global, the client was able to accelerate its deployment schedule. Its development team was able to rewrite 100 services in six weeks. Charter Global also played a major role in setting up the CI/CD process for microservices, which enabled them to deploy any service with the click of a button. This reduced issues and complaints from their customers. In addition, saving them thousands of development man-hours.
