The document discusses various software architecture concepts, primarily contrasting monolithic architecture with microservices architecture. Monolithic applications have a single code base, making deployment simple but challenging for scaling and upgrades, while microservices consist of smaller, independently deployable services that communicate via HTTP, offering improved scalability and less dependency. Additionally, it introduces the API gateway and the Eureka server, which functions as a discovery server, keeping track of client-service applications.

-Advantages of microservices.
-Microservices Arhitecture.
-How two microservices communicate with each other.
-What is Api Gateway.
-What is Eureka Server.
-We will do practical.

3. Monolithic Architecture-:
Monolithic application has single code base with multiple modules.
Single Jar Will Be Created For This

4. Advantages Monolithic Architecture-:
-Simple to develop
-Simple to deploy
-Problem of network latency are relatively less.
Disadvantages Monolithic Architecture-:
-Scaling is difficult
-For every single change redeployment is needed
-Difficult to adapt new technology
-Single bug may down your whole application

5. What is Microservices?
-Microservices are small services that work together
-these services communication with each other directly using http protocols

6. Advantages Microservices Architecture-:
-Possible to change or upgrade each service individually rather
than upgrading in the entire application
-One service may down without impacting to others
-Easily use different technology for building different
microservices,
-Less dependency, loosely coupled
-Scalability improvements.

8. Api Gateway-:

9. How To Create Api Gateway-:

11. What is Eureka Server.
-Eureka Server is an application that holds the
information about all client-service applications.
-Every Micro service will register into the Eureka server
and Eureka server knows all the client applications
running on each port and IP address.
-Eureka Server is also known as Discovery Server.

12. How to build Eureka Server.

14. Use Case-:

15. Ports & Dependency We Will Use-:
