The key characteristics of a microservices architecture translate very clearly to benefits, which include:
Scalability: Because microservices can be scaled independently, your organization can allocate resources efficiently based on the demands of each service. This granular control over which microservice resources to scale up (and down) can yield more optimal resource allocation.
Flexibility: The decentralized governance of the microservices approach increases the freedom afforded to developers and their teams. This flexibility to choose the best tools and technologies as needed lets developers work more quickly, unhampered by technology decisions from other teams, thereby fostering innovation and adaptability.
Faster Time to Market: Changes in one microservice don’t require a full system rebuild and deployment. When microservices can be independently deployed, you get faster delivery of new features and updates.
Easier Maintenance and Updates: The single responsibility principle makes it simpler for developers to understand, maintain, and update individual microservices. They can focus on the microservice for which they’re responsible, using the microservice’s API as the contract through which other microservices will interface.
Resilience: Fault isolation helps ensure that the failure of a single microservice doesn’t bring down the entire application. This promotes system reliability and improves availability and uptime, leading to bottom-line benefits for your organization as a whole.
