Breaking monolithic applications into microservices
Before we get into the topic of breaking a monolithic application into microservices, let us understand what a monolithic architecture is and the need to go through the process from a monolithic architecture to microservices architecture.
What is monolithic architecture?
Applications that are designed using single-tiered or monolithic architectures have all their functions in a single package to deploy and run. For example, when you develop a server-side Java application, it has different layers in the architecture, namely the following
- Presentation layer: This is where all the end user HTTP/HTTPS requests are handled, and responses are sent back
- Business logic layer: This is where the application’s business logic is handled
- Persistent/Database layer: This is where the data access objects are persisted in the database
