In today’s cloud-native landscape, managing and observing multiple clusters is a common requirement for ensuring robust, scalable, and reliable service delivery. However, achieving a comprehensive view across these clusters, while maintaining performance and limiting costs presents numerous challenges. Drawing from our customer experience in multi-cluster environments, we have a few critical lessons to guide practitioners toward effective multi-cluster observability. In this session, we delve into practical strategies and best practices covering areas such as centralized monitoring, logging, tracing, visualization, and analytics.
