Microservices

Many traditional applications are built as a monolith. A monolithic application is deployed as a single unit on a single server. The monolithic application is easy to develop and deploy. However, as the application grows, it becomes more and more difficult to maintain and scale. A small change in the application may require the entire application to be rebuilt, retested, and redeployed. Moreover, if one part of the application needs to be scaled, the application must be scaled as a whole, which is not cost-effective. In addition, if one part of the application fails, it may affect the entire application.

This is where microservices come in. A microservice is a small, independent service that is responsible for a specific business domain. Each microservice has its own database and dependencies. It can be developed, deployed, and scaled independently. These microservices communicate with each other through programmatic interfaces, such as web APIs or message queues.
