A Full Approach to Migrating to Microservices Architecture

Today, the marketplace is an increasingly demanding always-on service. There is a need for enterprises to modify their technological approach by incorporating highly flexible and scalable architectures with quick and efficient adaptation to the modern market. These market influences have led to the rise in the demand for microservices architecture which offers more benefits.

The larger a system grows, technology issues arise if a software product is based on monolith architecture. Here, enterprises will need a solution in microservices architecture so as to fix collaboration and workflow issues on a project, due to rising complexity.

Microservices Architecture

Rather than building around technology like UI, middleware, and database, Microservices is focused on business functionality. It is a self-contained unit representing one module’s end to end functionality. One application constitutes one or many modules, whereas, a set of microservices assembled represents an application.

Migration Approach

In order to migrate to microservices, you must first take a decision on a microservices architecture. Before trying to optimize its implementation, it is necessary to evaluate how the services will interact. Next, continually optimize those speed gains that microservices architecture provide. This requires flexibility in the tools used in deploying the architecture.

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

• 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.

Microservices Benefits

Microservices architecture comes with a lot of benefits. Some of which include:

• Agility: Banking and Fintech applications are designed to be complex, constantly evolving and scaling, integrating with multiple systems (internal/external) as well as demand high security at various levels. Microservices supports greater agility in building and managing these systems making it highly suitable.
• Scalability: Unlike a monolithic application that has a lot of resources wasted for scaling services that are not required since they are all packed together in a single deployable unit, each microservice can scale independently without affecting the other microservices.
• Availability: Failure of one microservice does not affect other microservices, as the failed one can be uninstalled and rectified quickly with minimal downtime. It does not require the entire application to be brought down for maintenance, unlike the monolith application.
• Maintenance: A separate microservice is created for each business service. This means that the amount of code base is reduced and functional changes can be faster and more efficient due to the decomposed architecture.
• Separation of Business Concerns: Microservices offer a clear separation of business concerns as each microservice caters to a particular business functionality.
• Faster Deployment: by catering for a single business functionality, the code based required for microservices are reduced, creating rapid deployment.
