A retail platform wants Kafka for microservice events, database replication, logs, analytics, worker tasks, and batch exports. Learn how to separate strong Kafka use cases from workloads that need queues, databases, object storage, ETL tools, or a different streaming platform.
Build a complete Kafka workflow for order events, from serialization and producer retries to consumer groups, rebalancing, offset commits, database updates, and recovery. The focus is preventing silent loss, duplicate processing, broken ordering, and unstable consumers.
Learn how to design Kafka topics for an inventory pipeline that preserves per-item ordering, scales consumer processing, survives broker failures, and retains the right data without treating Kafka like a general-purpose database.
Redesign a synchronous order workflow as a Kafka event flow, assign clear responsibilities to producers, brokers, consumers, controllers, and supporting tools, then test the consistency, retry, replay, contract, and operational risks before production
Learn how tracing, spans, Jaeger, OpenTracing, APM, and service monitoring help Java teams connect user requests to sub-calls, metrics, logs, and business KPIs.
Learn how to define uptime, planned downtime, unplanned downtime, recovery metrics, clustering, quorum, high availability, disaster recovery, backups, and deployment placement.
Learn how to design security into Java applications with input validation, least privilege, sandboxing, firewalls, IPS tools, static analysis, dependency checks, and security standards.
Learn how authentication, authorization, IAM, SSO, user stores, tokens, RBAC, and PBAC fit together when designing secure Java applications.
Learn how to design gRPC services in Go with Protobuf contracts, generated code, streaming RPCs, interceptors, graceful shutdown, secure clients, and production-ready observability.
Learn how to use events to decouple Go services, define stable message contracts, build reusable producers and consumers, handle failed messages, tune broker clients, and observe the system in production.
