Beyond Docker 25: Multi-Cluster Serverless Observability with Istio 1.20

The container ecosystem is evolving rapidly, with Docker 25 introducing foundational updates for modern workloads. However, as organizations adopt multi-cluster serverless architectures, traditional container observability falls short. Enter Istio 1.20: the service mesh update that redefines observability for distributed, serverless multi-cluster environments.

The Shift Beyond Docker 25

Docker 25 brought improvements to build speed, image management, and rootless container support, but it was never designed for the complexity of multi-cluster serverless deployments. Serverless functions spin up and down dynamically across clusters, creating ephemeral workloads that traditional Docker monitoring tools can’t track consistently.…
