Microservice Architecture

Microservice architecture breaks down an application into a collection of small, loosely coupled services. Each service focuses on a distinct business feature and is capable of independent development, deployment, and scaling. Communication between services typically occurs over a network through lightweight protocols such as HTTP or message queues. Greater flexibility, scalability, and the ability to use various technologies for various services are all made possible by microservice designs.

Advantages of Microservice Architecture:

1. Scalability: Each microservice can be independently scaled based on its specific demands, allowing efficient resource utilization.
2. Flexibility: Microservices allow independent development and deployment of individual services, enabling teams to work autonomously and adopt diverse technologies.
3. Resilience: Failures in one microservice do not bring down the entire system, as other services can continue to function.
4. Continuous Delivery: Smaller, independent services are easier to test, deploy, and update, enabling faster iterations and continuous delivery practices.

Considerations of Microservice Architecture:

1. Complexity: Microservice architectures introduce distributed systems’ complexity, including network communication, service discovery, and data consistency across services.
2. Operational Overhead: Managing and monitoring a large number of services can require additional operational effort and infrastructure.
3. Service Coordination: Service-to-service communication and ensuring data consistency across services can be challenging.

There are various architecture patterns in design patterns but for creating and deploying applications, the most frequently used architecture patterns are listed below that we are going to discuss below that are as follows:

1. Monolithic Architecture 
2. Microservice Architecture
3. Serverless Architectures
