#Kafka

A hands-on series on building a complete Microservices system with Quarkus 3.x — the "Supersonic Subatomic" Java framework designed specifically for Cloud Native and Kubernetes. Using PostgreSQL as main database, Keycloak for Authentication & Authorization (OIDC), Apache Kafka for Event-Driven Communication, gRPC for high-performance inter-service. From creating your first project with Dev Services, building a REST API with Panache, to deploying production on Kubernetes with GraalVM Native Image. Includes Fault Tolerance, OpenTelemetry Observability, Contract Testing, CI/CD Pipeline and Production Readiness Checklist. Actual project: E-Commerce Platform system includes 5 microservices.

In-depth course on designing and building a Notification system capable of sending millions of emails at once. You'll learn how to design an event-driven architecture with message queues, build high-performance email pipelines, handle rate limiting, retry, and dead letter queues, ensure deliverability with SPF/DKIM/DMARC, and deploy a production-ready system. Combine theory with hands-on practice using Kafka, Redis, PostgreSQL, Amazon SES, SendGrid. Suitable for Backend Engineers, System Architects who want to solve the problem of sending large-scale emails in practice.

Comprehensive series on Cloud Native Microservices architecture — from container platforms, Kubernetes, microservices design principles (DDD, Bounded Context), communication models (REST, gRPC, Event-Driven), to Data Management (CQRS, Saga, Event Sourcing), Service Mesh, Observability, Resiliency Patterns, CI/CD GitOps and Security. Combine solid theory with practical architecture for production systems.
