10 articlesBuilding your own AI SRE moves the toil; it does not remove it
Chronosphere leaders argued in The New Stack that engineering teams should build their own AI SRE to map systems, investigate incidents and support reliable delivery at scale. The operational read is narrower: an in-house AI SRE is a second production system with its own on-call, its own change-management story and its own place in the audit trail.
Aug 2, 2026 · Maya OkonkwoRunners & infrastructureLinkerd federation keeps the app running when a whole Kubernetes cluster dies
A CNCF walk-through by Dominik Táskai wires three GKE clusters into a full-mesh Linkerd multicluster and kills one. The nine-pod frontend rebalances across the surviving six with no application changes, but the setup pays a real price at the VPC, node-count and controller layers.
Jul 28, 2026 · Maya OkonkwoRunners & infrastructureThe 60% idle GPU that turned out to be a network policy
A CNCF write-up walks through a distributed Kubeflow training job whose GPUs sat around 60% idle while every pod reported healthy. The failure lived one layer down, in a Cilium policy enforcing zone boundaries that gradient sync had to cross.
Jul 23, 2026 · Maya OkonkwoRunners & infrastructureGPUs keep falling off the PCIe bus, and standard node health does not notice
AWS engineers write up what running Kubernetes at Amazon EKS scale taught them about GPU node failure, and why the default node health model has nothing to say when the GPU just vanishes from the bus.
Jul 20, 2026 · Maya OkonkwoRunners & infrastructureAWS puts gray zone failures into the EKS control loop
The New Stack details how AWS treats non-obvious availability zone degradation as its own category on EKS, with zonal shift moving traffic away from an impaired zone before the traditional alarms fire. For CI/CD teams, it reframes what a regional resilience test needs to cover.
Jul 12, 2026 · Maya OkonkwoPlatform engineeringetcd v3.7 adds a streaming range API and drops the legacy v2 store
SIG etcd shipped v3.7.0 with a RangeStream API that chunks large read responses instead of buffering them, plus faster lease handling under load and the removal of the legacy v2 backing store. Kubernetes will expose the feature in v1.37 behind a gate.
Jul 9, 2026 · Maya OkonkwoPlatform engineeringAWS reworks the EKS control plane and starts selling it in sized tiers
Amazon EKS engineers detail a set of architectural changes to how the service runs the Kubernetes control plane, including a purpose-built journal that replaces etcd's Raft consensus, and a new tier-priced product, EKS Provisioned Control Plane, that lets customers reserve API and scheduling capacity ahead of bursty workloads.
Jul 1, 2026 · Maya OkonkwoIncident responseAWS wires its DevOps Agent into PagerDuty incidents
AWS has paired its DevOps Agent with PagerDuty so that the moment an incident is created, the agent runs a root-cause investigation across AWS telemetry, deployment history and a short list of third-party observability tools, posting its findings back onto the incident record.

AWS has moved its DevOps Agent from preview to general availability, shipping it alongside the Datadog MCP Server so the agent can correlate monitoring signals with AWS-deployed infrastructure during an incident. The badge change is the smaller story; the bigger one is what SRE teams now have to write down before the agent touches production.

Flipkart's central reliability engineering team won the CNCF End User Case Study contest for a multi-tenant chaos engineering platform on Kubernetes that runs roughly 90% of its experiments in staging clusters and contributed five fixes upstream to LitmusChaos. The next step on the roadmap is to wire chaos testing into the CI/CD pipeline as a mandatory phase.
