  3. 3. Jyaasa : We Design, Build and Develop Products Introduction Microservices is an architectural style that structures an application as a collection of loosely coupled services, which implement business capabilities. The microservice architecture enables the continuous delivery/deployment of large, complex applications. It also enables an organization to evolve its technology stack.

  5. 5. Jyaasa : We Design, Build and Develop Products Benifits Developer independence: Small teams work in parallel and can iterate faster than large teams. Isolation and resilience: If a component dies, you spin up another while and the rest of the application continues to function. Scalability: Smaller components take up fewer resources and can be scaled to meet increasing demand of that component only. Lifecycle automation: Individual components are easier to fit into continuous delivery pipelines and complex deployment scenarios not possible with monoliths. Relationship to the business: Microservice architectures are split along business domain boundaries, increasing independence and understanding across the organization.
  6. 6. Jyaasa : We Design, Build and Develop Products Drawbacks • Developers must deal with the additional complexity of creating a distributed system. • Deployment complexity. In production, there is also the operational complexity of deploying and managing a system comprised of many different service types. • Increased memory consumption. The microservice architecture replaces N monolithic application instances with NxM services instances. If each service runs in its own JVM (or equivalent), which is usually necessary to isolate the instances, then there is the overhead of M times as many JVM runtimes. Moreover, if each service runs on its own VM (e.g. EC2 instance), as is the case at Netflix, the overhead is even higher.
