Summary
Highlights
Introduction to System Design00:00:00
An overview of the shift from mid-level to senior engineering, focusing on designing scalable, production-ready systems from the ground up.
Building Blocks: Single Server Setup00:03:05
Establishing the foundation of system architecture with a single server setup, explaining DNS, IP addresses, and the differences between web and mobile client requests.
Database Selection: SQL vs. NoSQL00:07:30
Comparing relational (SQL) and non-relational (NoSQL) databases, covering ACID properties, consistency, and when to use specific storage models.
Scaling Strategies: Vertical vs. Horizontal00:13:32
Explaining the difference between scaling up (vertical) and scaling out (horizontal), and why horizontal scaling is preferred for production.
Load Balancing00:17:28
Deep dive into load balancing algorithms like Round Robin, Least Connections, and IP Hashing, along with how load balancers ensure fault tolerance.
API Design Principles00:31:00
Establishing the core principles of effective API design, exploring REST, GraphQL, and gRPC, and managing the API lifecycle.
API Protocols and Networking00:47:18
Understanding the networking stack, comparing HTTP/HTTPS, WebSockets, AMQP, and gRPC, and choosing the right protocol for specific performance needs.
Transport Layer: TCP vs. UDP01:01:04
Detailed comparison of TCP (reliable, connection-based) and UDP (fast, connectionless) protocols and their specific use cases in real-world systems.
Mastering RESTful APIs01:05:07
Practical guide to designing REST APIs with proper resource modeling, status codes, error handling, filtering, sorting, and pagination.
GraphQL Deep Dive01:19:14
Exploring the GraphQL architecture, schema design, mutation patterns, and error handling for highly flexible data requests.
Authentication Strategies01:25:21
Differentiating between authentication and authorization, covering methods like API keys, session-based storage, and JWT token authentication.
