Recommended: 16GB RAM laptop for running multiple local containers & brokers.
Free Cloud Option: Play with Docker, Hoppscotch.io & GitHub Codespaces run in browser.
Laptop Essential
Read Microservices.io on phone; building & tracing multi-service APIs needs a laptop.
Internet: 3–5 Mbps.
Hardware / Kit: None required.
Zero prior experience required — core concepts & first hands-on builds.
Design predictable endpoints using nouns, HTTP methods, status codes, and pagination.
Document APIs first with OpenAPI 3.1 and test every endpoint systematically.
Build real multi-part projects, tooling fluency, and problem-solving speed.
Protect APIs against abuse, replay attacks, and duplicate payment charges.
Know when a well-structured modular monolith beats premature microservices.
Production patterns, architecture, automation, and security rigor.
Decouple services cleanly with message queues (RabbitMQ/Kafka/Redis) and eventual consistency.
Scale, observability, testing, leadership, and real-world deployment.
Prevent cascading failures across services and trace requests end-to-end.
