1.2 Principles of Scalability, Availability, and Reliability

• Purpose: Learn core principles that guide the design of robust systems.
• Chapters:
  1. Scalability - Vertical scaling vs horizontal scaling. - Stateless vs stateful architectures. - Examples of scalable designs (e.g., distributed databases).
  2. Availability
     • Definitions: Availability vs uptime.
     • Designing for high availability (HA).
     • Redundancy and failover mechanisms.
  3. Reliability
     • Reliability vs availability.
     • Fault tolerance and graceful degradation.
     • Techniques for improving reliability (e.g., retries, idempotency).
  4. Trade-offs Between Scalability, Availability, and Reliability
     • How to balance trade-offs based on requirements.
     • Real-world examples of trade-offs.
