Today, most of our applications are hosted in the cloud. But what if we leveraged multiple providers for a single application or platform?

The theory is attractive: cherry-picking the best services from each provider to build the ultimate architecture. The reality? Cloud providers that are "more equal than others" and a labyrinth of technical complexities—where network latency, fragmented data, and incompatible APIs threaten both your SLAs and your peace of mind.

In this session, we will tackle the challenge of designing a multi-cloud platform based on a real-world use case.

From defining bounded contexts to addressing production hurdles, security, and API design, we will navigate the pitfalls inherent to this architecture while highlighting essential best practices.

Finally, we will explore how a thorough understanding of customer needs and a pragmatic risk analysis can guide design choices to deliver a coherent, end-to-end vision.

Shipping code is good. Shipping a new feature without breaking the rest of the system is even better!

Every release today brings the risk of regressions or bad interactions between existing and new functionality. And what about deploying to only a subset of users? That’s even trickier.

Feature flagging decouples code deployment from feature activation, allowing you to turn blocks on or off at runtime without redeploying.

Fortunately, this practice has been growing with open‑source tools and solid engineering habits. However, beyond simple if‑then‑else, most available solutions are proprietary, heavy or costly to set up.

OpenFeature, a CNCF project, offers an open specification for unified feature flagging, usable both server‑ and client‑side regardless of the backing store.

In this workshop we’ll add a new feature to an existing Java/Angular application and drive its activation through feature flags. Along the way we’ll cover key topics: error handling, A/B testing, progressive rollouts, targeting and observability.

By the end, you’ll know how to deliver faster, safer and with confidence.
