Web Service

A Web Service acts as the representational layer that stands in front of the internally complex backend components.

In this introduction, we’ll cover the essential concepts needed to build a robust web service:

1. Microservice :

• Explore the Microservice architecture, its advantages, and how it differs from Monolith systems.
• Learn about the challenges of service coupling and how Messaging can help decouple large-scale systems.

2. Service Cluster:

• Understand best practices for managing clusters of services, including critical concepts like Health and High Availability (high availability).
• Explore the two main types of service clusters: Stateless and Stateful .

3. Communication Protocols:

• Get an overview of key protocols such as HTTP , WebSocket , and Server-Sent Events , as well as streaming protocols like WebRTC and HLS .

4. Load Balancer:

• Discover how load balancers distribute incoming traffic across multiple servers, ensuring high availability and reliability.
• Learn about the differences between common types of load balancers: Layer 4 Load Balancer and Layer 7 Load Balancer .

5. API Design:

• Develop an understanding of RESTful API principles, including statelessness, uniform interfaces, and self-descriptive messages.
• Learn about implementing API pagination for efficient data retrieval.

These foundational topics will equip you with the knowledge to design and implement effective web services.
