Building Distributed Event-Driven Architectures Across Multi-Cloud Boundaries

Tuesday Apr 8 / 10:35AM BST, Fleming (3rd Fl.)

Abstract

“Event-driven architecture” is a frequently discussed topic in architectural conversations. However, in today’s multi-cloud landscape, the more pressing question is: “How can we implement these patterns across cloud boundaries without compromising reliability?

While architects can create appealing event-driven designs, engineers face the daunting task of building distributed systems that must seamlessly integrate with numerous third-party services, manage cross-cloud communication, handle varying event delivery guarantees, and ensure consistency across diverse cloud services.

Key Takeaways:

  • Understanding why distributed events behave unexpectedly across cloud boundaries and how to handle it
  • Building asynchronous systems spanning multi-cloud that are resilient and perform predictably under high load
  • Enhancing observability with a focus on health checks and monitoring across cloud boundaries
  • Challenges and approaches to maintain data consistency

Interview

I design cloud-native architectures that help organizations navigate complex digital transformations, with a focus on multi-cloud strategies and event-driven system design.

My motivation behind the talk is to bridge the gap between event-driven architecture concepts and the challenging realities of implementation across cloud boundaries.

Software architects, Cloud engineers, Technical leaders designing distributed systems and multi-cloud infrastructures

Practical strategies and actionable insights for building resilient, observable, and consistent distributed event-driven systems that can seamlessly operate across different cloud boundaries.

Quantum computing. Its potential to revolutionize complex computational problems, particularly in sectors like finance, cybersecurity, and advanced scientific modeling is rapidly emerging.

One interesting thing I have learned is that  QCon isn't just a conference - it's a career accelerator. Though QCon conferences may require you to put your day to day sprint tasks behind and lose your incremental progress at work, attending the QCon conference gives you exponential advancement in your career. It changes your perspective on how to look at the problems.
