Typical Microservice Architecture

The diagram above shows a typical microservice architecture.

Key Components

• Load Balancer: This distributes incoming traffic across multiple backend services.

• CDN (Content Delivery Network): CDN is a group of geographically distributed servers that hold static content for faster delivery. The clients look for content in CDN first, then progress to backend services.

• API Gateway: This handles incoming requests and routes them to the relevant services. It talks to the identity provider and service discovery.

• Identity Provider: This handles authentication and authorization for users.

• Service Registry & Discovery: Microservice registration and discovery happen in this component, and the API gateway looks for relevant services in this component to talk to.

• Management: This component is responsible for monitoring the services.

• Microservices: Microservices are designed and deployed in different domains. Each domain has its database.
