Highlights from CNCF’s First Open Observability Summit - OpenObservability Talks S6E02

We are overdue for a vendor neutral industry wide event dedicated to our favorite topic - open observability. Last month (June 2025) the Cloud Native Computing Foundation (CNCF) ran the first-ever Open Observability Summit, bringing together the world’s best experts in the field in a day packed with talks from project maintainers, end users and practitioners. We’re proud partners of the event, and are here to bring you the highlights from this industry-shaping event. This special episode has two parts, one recorded onsite before the event, covering conference goals, and insights from the talk submissions, and the other recorded after the event, covering the highlights of the events and the talks. The guests for is episode are two observability veterans: Alok Bhide, member of the event’s content committee and head of product innovation at Chronosphere; and Henrik Rexed, developer advocate at Dynatrace, CNCF Ambassador, and host of Is It Observable podcast. Catch up on everything you need to know from the first-ever Open Observability Summit.
