Stephan Schwarz, DevOps Engineer at iits-consulting, explains why performance testing Kubernetes workloads is more complex than testing isolated applications. He emphasizes that you're never just testing your application - you're testing the entire system chain from client to infrastructure.

Stephan breaks down the components that affect your test results: the testing clients themselves, network infrastructure (firewalls, routers, switches), and Kubernetes-specific shared resources like ingress controllers, CNIs, CSIs, service meshes, plus external dependencies like load balancers and databases.

The key insight is developing awareness of these interconnected components when interpreting performance test results, rather than assuming bottlenecks are always in your application code.

AI container images are getting larger, and pulling them before a workload can run is a real bottleneck. Phil Estes from AWS explains how SOCI (Seekable OCI) tackles this.

SOCI is a lazy-loading technology: instead of pulling the entire image upfront, it starts the container immediately and fetches layers on demand. AWS also built a fast pull snapshotter for ultra-large EKS clusters with thousands of nodes, where even small startup delays compound at scale.

Both are open source and work directly with Containerd — no EKS required.

Artem Lajko discusses strategies for managing observability data costs in Kubernetes environments.

He explains how 95-99% of collected metrics and logs often go unused and shares two key approaches: separating application syslogs from user logs and implementing retention policies. Through a real example from the Hamburg Port Authority, where water level metrics need multi-year retention, Artem demonstrates how domain-specific requirements should guide data retention decisions rather than applying blanket policies.
