Microservices Learning Path

Learn Microservices: Design Distributed Systems That Scale

Microservices is where backend careers accelerate. This path covers the architecture, decomposition, API gateways, resilience patterns, Kafka messaging and the system-design questions senior interviews ask — with honest guidance on when a monolith is still the right choice.

Microservices Roadmap

Follow the Path in Order

01

Fundamentals 3 tutorials

What microservices are, and honestly when a monolith is the better call.

beginnerMicroservices Architecture ExplainedSee how the pieces fit: services, API gateway, discovery, per-service databases and messaging. A clear, example-driven tour of microservices architecture.6 min read beginnerMicroservices vs MonolithNeither is universally better. Learn how microservices and monoliths really differ across deployment, scaling, data and team size, and which fits your project.6 min read beginnerWhat Are Microservices?A grounded introduction to microservices: what they are, how services talk to each other, the real trade-offs, and when a monolith still wins.7 min read

02

Domain-Driven Design 1 tutorials

Split a system into services along domain boundaries, not database tables.

beginnerDomain Driven Design BasicsLearn the core DDD ideas — bounded contexts, aggregates, and ubiquitous language — that tell you where one microservice should end and the next should begin.7 min read

03

API Gateway & Discovery 1 tutorials

Route, aggregate and discover services at runtime.

beginnerWhat Is an API Gateway?Understand the API gateway: the single front door that routes, authenticates, and rate-limits traffic to your microservices — plus when you do not need one.6 min read

04

Resilience 1 tutorials

Keep the system up when a dependency is down.

beginnerCircuit Breaker PatternLearn how the circuit breaker pattern protects microservices from cascading failures, its three states, and how to implement it with Resilience4j in Spring Boot.7 min read

05

Data Patterns 1 tutorials

Manage data across services without distributed transactions gone wrong.

beginnerSaga PatternLearn how the saga pattern maintains data consistency across microservices using local transactions and compensating actions, with choreography and orchestration examples.7 min read

06

Messaging & Kafka 1 tutorials

Event-driven communication with Kafka.

beginnerApache Kafka BasicsA hands-on introduction to Apache Kafka for microservices: topics, partitions, producers, consumers, and consumer groups, with Spring Boot code you can run.6 min read

07

Observability 1 tutorials

See what a distributed system is actually doing.

beginnerObservability vs MonitoringMonitoring tells you a service is broken; observability tells you why. Learn the difference through logs, metrics and traces with practical microservices examples.6 min read

08

Docker & Kubernetes 1 tutorials

Package and run services the way they ship to production.

beginnerDocker Basics for MicroservicesPackage a microservice into a portable container. Learn Docker images, containers, Dockerfiles and Compose with hands-on examples built around a Spring Boot service.6 min read

09

Security 1 tutorials

Authentication and authorization across service boundaries.

beginnerMicroservices Security Best PracticesSecure a distributed system the right way. Learn API gateway authentication, JWT validation, mTLS, secrets management and least privilege with practical examples.6 min read

10

Architecture Interviews 1 tutorials

The system-design questions microservices roles ask.

beginnerMicroservices Interview Questions and AnswersA structured walkthrough of the microservices interview questions freshers actually face, grouped by topic with crisp answers, code and the follow-up traps to expect.6 min read
