Just as applications moved from monoliths to microservices, modern frontend architecture is evolving towards micro frontends, often leveraging frameworks like Next.js. This shift allows teams to deliver better experiences and iterate faster by combining traditional components with server-side rendering and server components. However, this creates "gray zones" in visibility, as traditional client-side monitoring struggles to identify whether performance bottlenecks come from the user's browser or the backend infrastructure.

Changhyeon Yoon, a DevOps Engineer at MIRI D.I.H and Datadog Ambassador, will share how his team eliminated these blind spots by implementing APM directly on frontend servers to establish true end-to-end observability. He will dive into how they unified infrastructure metrics, server-side APM, client-side RUM, and Browser Profiling into a single view to get a holistic understanding of the user experience.

By the end of this session, you will be equipped with a blueprint for monitoring the entire lifecycle of modern web applications, ensuring stability and performance across both client-side interactions and the underlying server layers.
