Hands-on System Design with Java Spring Boot — Task Scheduler Implementation

Build. Architect. Deploy.

In today's distributed systems, reliable task execution is mission-critical. Whether you're sending millions of scheduled emails, orchestrating complex data pipelines, or managing microservice workflows, a robust scheduler is the backbone of modern applications.

This comprehensive 60-lesson course takes you beyond basic Spring annotations into the world of real-world system design and implementation. You'll architect, build, and deploy a production-ready distributed scheduler from the ground up.

What You'll Build

A complete, enterprise-grade distributed task scheduler featuring:

• Advanced Scheduling: Cron expressions, recurring tasks, dynamic scheduling

• Distributed Architecture: Leader election, cluster coordination, horizontal scaling

• Production Features: Persistence layers, execution history, audit trails

• Observability Stack: Comprehensive monitoring, metrics, and real-time debugging

• Resilience Patterns: Circuit breakers, retry mechanisms, graceful degradation

• Modern Interfaces: REST APIs with optional web dashboard

• Integration Ready: Kafka/RabbitMQ messaging, webhook notifications

• Cloud Native: Kubernetes deployment with auto-scaling and health checks

Who This Is For

Experienced Engineers looking to level up their system design skills Software Architects wanting hands-on distributed systems experience
DevOps/SRE Professionals needing deeper understanding of schedulers they operate Data Engineers building reliable pipeline orchestration Ambitious Developers ready to tackle complex, real-world problems

Why This Course Stands Apart

🏗️ System Design First

Start with architecture decisions, trade-offs, and design patterns before writing a single line of code.

⚖️ Real-World Trade-offs

Navigate CAP theorem implications, consistency models, and performance vs. reliability decisions that matter in production.

🔧 Progressive Construction

Each lesson builds upon the previous one, creating a cohesive system rather than isolated examples.

📊 Observability by Design

Learn to build systems that are not just functional, but debuggable, monitorable, and maintainable.

🎯 Production Mindset

Every decision considers scalability, security, monitoring, and operational concerns from day one.
