microservice and monolithic architectures.

Before microservices, let's see what a monolithic architecture is.

A monolithic architecture is like a huge container within which all software components of an application are assembled, and all the components share a same database.

👍 advantages of monolithic architecture:

• easy deployment.
• easier to develop.
• end to end testing can be performed faster.
• easy debugging.

👎 Disadvantages of monolithic architecture:

• Scalability: Individual components cannot be scaled.
• Reliability: if one feature goes down, the entire system goes down
• Adoption of technology is restricted.
• Lack of flexibility.

🚀 Microservice architecture

A microservices architecture is an architectural solution that is based on a collection of independently deployable services. These services have their own business logic and database, and they serve a specialised purpose.

👍 Advantages of Microservices

• Flexible scaling
• Continuous deployment: frequent and faster release cycles.
• Highly maintainable and testable.
• Independently deployable.
• High reliability: one failure does not bring down the entire application.

👎 Disadvantages of Microservices

• Difficult to manage a large number of services.
• Each microservice has its own set of logs, making debugging more difficult.

Components of Microservices Architecture:

🔵 Identity Provider: These client requests are subsequently forwarded to identity providers, who authenticate the requests and relay them to API Gateway. The queries are subsequently routed to internal services using a well-defined API Gateway.

🔵 Static Content. Following internal communication, the Microservices distribute static material to a cloud-based storage service that may provide it directly to clients via Content Delivery Networks (CDNs).

🔵 Management: This component is responsible for balancing the services on nodes and identifying failures.

🔵 Service Discovery: it keeps a list of services on which nodes are situated, it acts as a guide for Microservices to discover the path of communication between them.
