- 3. Monolithic Applications A monolithic application is built as a single unit. Enterprise Applications are built in three parts, • Database • Client-side (user) • Server-side application
- 5. Problems of Monolithic Applications • Simple application will have grown into a monstrous monolith. • The larger the application, the longer the start-up time is. • Difficult to scale because different modules have conflicting resource requirements. • Reliability • Extremely difficult to adopt new frameworks and languages.
- 6. Microservices Microservice architecture is a method of developing software applications as a suite of independently deployable, small, modular services in which each service runs a unique process and communicates through a well-defined, lightweight mechanism to serve a business goal.
- 9. A monolithic application pull all faction into single process A microservice architecture application put each element into a separate service Scale by replicating Scale by distributing these services
- 11. Benefits of Microservices • It tackles the problem of complexity. • Each service to be developed independently • Each microservice to be deployed independently. • Each service to be scaled independently.
- 12. Drawbacks of Microservices • Deploying a microservices-based application is also much more complex. • Microservices is the partitioned database architecture. • Testing a microservices application is also much more complex.
- 13. Summary • A Monolithic architecture only makes sense for simple, lightweight applications. • You will end up in a world of pain if you use it for complex applications. • The Microservices architecture pattern is the better choice for complex, evolving applications.

Editor's Notes
- #4: At the core of the application is the business logic, which is implemented by modules that define services, domain objects, and events. Surrounding the core are adapters that interface with the external world. Examples of adapters include database access components, messaging components that produce and consume messages, and web components that either expose APIs or implement a UI. Applications written in this style are extremely common. They are simple to develop since our IDEs and other tools are focused on building a single application. These kinds of applications are also simple to test. Monolithic applications are also simple to deploy. You just have to copy the packaged application to a server. You can also scale the application by running multiple copies behind a load balancer. In the early stages of the project it works well.
