Best Practices for Building a Microservices Architecture

Our previous blog explained the benefits of Microservices over monolithic architecture, which implies that the development processes and architectures of the past cannot support your current requirements. Your application cannot handle your user volume with the monolithic architecture, cannot move fast enough, and your users will not have a good experience.

Switch to Microservices architecture can be exciting for your business, as it promises next-level speed, control, deliverability, and innovative experiences for your users.

Unlike monolithic architecture, microservices architecture is an accumulation of loosely coupled independent services which are easy to deploy, scale and maintain. It helps in managing the application with great ease. Each service in microservice architecture has its server, database, and microservices architecture is a variant of service-oriented architecture(SOA). 

There are five core components of microservices architecture. They are Microservices, Containers, Service Mesh, ServiceDiscovery, and API gateway.

Best Practices to Build a Microservices Architecture 

1. Fitment

Keeping in mind your requirements, decide whether the microservices architecture is a good fit or not. One must not adopt microservices architecture because it is trending. Additionally, one must check the feasibility of breaking the current application into microservices with existing functionality.

2. Stakeholder Alignment

All stakeholders must be on board with the move to microservices architecture. Stakeholders must consider how much money, time, and technical knowledge are needed to transition infrastructure from monolithic to microservices. 

3. Team Building

Microservices architecture necessitates team building. Each microservice should have its own dedicated team. Each team must have the proper tools and skillful members to develop, deploy and manage a service. Also, the team members must be versatile to perform the operations autonomously. 

4. Keep Business Distinct from Microservices

Business functions and services must be distinct from microservices. It will aid in the creation of microservices that are the right size, neither too huge nor too little. If the microservices are too large, there is no clear benefit to employing them, and if the services are too small, operational costs skyrocket. 

5. Achieve Coherence

Develop loosely coupled services with good cohesiveness that cover a particular domain. Microservices have to be created with a defined aim to achieve high coherence, and you should focus on creating domain-specific services. 

6. APIs

To communicate between the services, use APIs and events. Services and events must be able to interface with API gateways. The API gateway monitors communication traffic and controls authentication, requests, responses, and throttling for services. 

7. Keep Vulnerabilities in Check

Keep in mind security vulnerabilities. Microservices are more vulnerable to attack due to their dispersed architecture. DevSecOps is hence perfect for security providing. 

8. Version Control

Each service should have its approach to version control and needs its repository to keep version control logs clean. In case the service goes down during the installation, these will come in handy. 

9. Compatibility

The service endpoints must be backward compatible, and the clients' contract testing should be done to avoid losing them. API calls made in response to user questions should have "backward" compatibility, making it easier to create a production-ready application. 

10. Monitoring 

The monitoring and logging system must be centralized with microservices architecture. A centralized logging system ensures that all microservices send logs in a consistent format. It helps to speed up error handling and root cause analysis. Furthermore, early detection of compromised resources aids in resource availability monitoring and security. 

Microservices architecture makes it easier to manage the application, but the transition is not a cakewalk. Although the approach to deploying microservices varies depending on the use case, these core best practices are constant.
