This is a hands-on lab with limited capacity.

"What if the secret to faster, simpler, and more domain-aligned delivery isn’t microservices—but modular monoliths?"

In the race to scale, microservices often feel like the inevitable choice. But for many teams, they introduce unnecessary complexity, slow down delivery, and create operational headaches. What if you could deliver just as fast—if not faster—while maintaining domain alignment and simplifying your architecture?

In this talk, we’ll challenge the microservices-first mindset and explore the power of modular monoliths: monolithic applications designed with clear domain boundaries and modular architectures. By aligning your application’s structure with Domain-Driven Design (DDD) principles, modular monoliths enable teams to:

  • Deliver features faster without the overhead of distributed systems.

  • Build scalable, maintainable systems with clear domain boundaries.

  • Delay—or even avoid—the transition to microservices until it’s truly necessary.

We’ll dive into real-world strategies for designing modular monoliths using DDD concepts like bounded contexts, context mapping, and domain events. Along the way, you’ll see case studies of teams who embraced modular monoliths to achieve faster development cycles, smoother deployments, and long-term scalability.

Why Attend?

  • Learn a Simpler Path: Discover how modular monoliths can simplify your SDLC while delivering domain-aligned results.

  • Master DDD Principles in Practice: Get practical tips for applying DDD to your architecture and development workflows.

  • Avoid Common Pitfalls: Understand when modular monoliths work—and when it’s time to consider microservices.

  • Gain Real-World Insights: Hear success stories (and hard lessons learned) from teams that balanced speed, simplicity, and scalability.

Who Should Attend: This talk is for software engineers, architects, and technical leaders who want to:

  • Reclaim simplicity without sacrificing domain alignment.

  • Deliver faster without drowning in operational complexity.

  • Rethink their approach to architecture with a focus on real-world outcomes.

Whether you’re building a new application or rethinking an existing one, this session will inspire you to make smarter architectural choices—without chasing trends.
