Microservices Architecture - Structured Study Notes
These notes keep the lecture flow: boundaries, communication, state, and resilience.
SECTION 1: Monolithic Microservices
Topic: Monolithic Microservices
Core idea: Monolithic vs microservices: pros and cons.
Explanation: This part compares a modular monolith and microservices.
Practical example: In a real system, this appears during release pressure: monolithic vs microservices: pros and cons.
Common mistake: A common mistake is confusing this topic with a similar term.
Connection: This topic connects to other lecture ideas by sharing cause and effect steps.
Topic: Monolith Easier Local
Core idea: A monolith is easier for one team, local debugging, and simple transactions.
Explanation: This part compares a modular monolith and microservices.
Practical example: In a real system, this appears during release pressure: a monolith is easier for one team, local debugging, and simple transactions.
Common mistake: A common mistake is confusing this topic with a similar term.
Connection: This topic connects to other lecture ideas by sharing cause and effect steps.
SECTION 2: Database Service Shared
Topic: Database Service Shared
Core idea: Database per service, shared DB, event sourcing.
Explanation: An API gateway should keep edge policies like auth, routing, quotas, and response shaping.
Practical example: In a real system, this appears during release pressure: database per service, shared DB, event sourcing.
Common mistake: A common mistake is confusing this topic with a similar term.

Topic: Tools Remove Repeated
Core idea: These tools remove repeated network code but do not fix poor domain boundaries.

SECTION 3: Small Checkout Change
Topic: Small Checkout Change
Core idea: A small checkout change can force full regression across unrelated modules.
