Practices

This final section transitions from theoretical concepts to practical application by examining several intricate systems from a design perspective. The topics are organized into two distinct parts:

• Abstract Design: This section focuses on designing each system conceptually, ensuring the architecture is platform-agnostic and applicable across self-managed infrastructures and cloud providers like AWS, Azure, etc.
• Implementation: This part specifies how to deploy and maintain the systems on AWS. This section requires a good understanding of cloud computing and AWS. You may wish to skip it if you are not familiar with these topics.

We will discuss the following applications:

1. Booking System

• Raises awareness about challenges in large-scale systems, such as Data Distribution and Concurrency Control.
• Involves working with a simple multi-region setup in AWS.

2. Chat System

• Explores how to develop a real-time application and maintain a WebSocket cluster.
• Demonstrates how to manage system complexity with Queuing.

3. Video-on-demand And Livestreaming System

• Examines a system that deals heavily with Media Storage.
• Covers the design of a system that relies mainly on background processing.
