Microservices architecture is an architectural approach that connects independent business functionalities in the form of microservices to build complex business applications. Leveraging microservices architecture, a large application can be built as a suite of modular components or services.
It is easier to build and maintain a complex application when broken down into many small pieces that work together. Each layer has its own small team working on it so they are completely decoupled and separated from each other, allowing each service to run its own unique process and communicate autonomously without depending on the other teams or applications.
The ability of being separated and recombined, protects the entire system from getting outdated over time and better facilitates agile processes, making it an appealing method for organizations to adopt, especially for those who are still utilizing monolithic architecture.
With monolithic architecture, an application is built as a single unified system, which is usually one code-base. A monolith is often deployed all at once, both front-end and back-end code together, regardless of changes.
