Microservices Architecture - Structured Study Notes
These notes keep the lecture flow: boundaries, communication, state, and resilience.
SECTION 1: Sre Reliability Reality
Topic: Sre Reliability Reality
Core idea: 01 Introduction SRE 02 Reliability Reality Failures are not exceptions — they are normal.
Explanation: Distributed failures are normal, so services need guardrails: strict timeouts, bounded retries with backoff, circuit breakers, and idempotency.
Practical example: In a real system, this appears during release pressure: 01 Introduction SRE 02 Reliability Reality Failures are not exceptions — they are normal.
