Cloud, DevOps & System Design for Java Backend with LogicBrace

Cloud, DevOps, Databases & System Design for Java Backend Engineers is a 401-page PDF guide covering everything a senior Java backend candidate is expected to know beyond the language and framework itself. It's 200 fully explained interview questions across 20 chapters, and — like every Logic Brace guide — every single answer includes a working, commented code example or config file, not just a definition.

The guide starts with Docker (fundamentals, multi-stage builds, image optimization for Spring Boot) and JVM tuning inside containers, then moves into Kubernetes — both general fundamentals and a dedicated chapter on running Java workloads well (probes, graceful shutdown, HPA, ConfigMaps). From there it covers AWS deployment (EC2, ECS, Elastic Beanstalk, serverless Java on Lambda with GraalVM native images), CI/CD pipelines, and Terraform for infrastructure as code. The second half goes deep on database engineering: SQL design and query optimization, transactions and isolation levels, database scaling patterns (replication, sharding), caching architecture at scale, and NoSQL/polyglot persistence. It closes with a full system design section — 10 high-level case studies (design a URL shortener, a rate limiter, a notification system) and 10 low-level, class-design problems (design a parking lot, an LRU cache, a vending machine) — plus a final chapter of realistic senior-level scenario questions that tie everything together.

This is the guide for candidates who already know Java and Spring but keep getting caught out by the "everything else" a senior interview loop tests: how you'd actually deploy and run a service, how you'd design its data layer to scale, and how you'd architect a system from a blank whiteboard. Every example is grounded in a real Java/Spring Boot context rather than generic, language-agnostic DevOps trivia.

Every question is level-tagged (Intermediate/Advanced), every chapter ends with revision-ready key takeaways, and the guide includes a clickable table of contents with bookmarks for quick navigation.
