Monolithic Architecture

In a monolithic architecture, the entire application is built as a single, tightly integrated unit. All components, modules, and functionalities are part of a single codebase and run within the same process. As an alternative to this architecture design, we can find service-oriented architecture (SOA) such as microservices.

Principles

• Developers can easily share code between modules and functionalities, but development and maintenance can be difficult as the application grows. Understanding the entire codebase can become increasingly difficult

• Scaling can be a challenge, as entire application needs to be scaled to support extra load of a single component.

• Are built using a single technology stack and database. Any changes or updates of technology affects entire application.

• Deploying changes to a monolithic application often requires updating the entire application, which can lead to longer deployment times and potential disruptions.

• Low fault tolerance and resilience, a single component it can potentially bring down the entire application.
