Rather than centralizing more telemetry, the answer is to move intelligence closer to where the data lives.Sun, 27 Sep 2026 00:00:00 GMTObservabilityObservabilityAI for SREInfrastructure Economicshttps://rajithattapattu.com/writing/kubernetes-cost-management-series/https://rajithattapattu.com/writing/kubernetes-cost-management-series/An overview of a three-part series on Kubernetes cost management: where the spend comes from, how to optimize it as a feedback loop, and how to run that loop as a FinOps practice with SRE Agents inside human-set boundaries.Sun, 27 Sep 2026 00:00:00 GMTEngineeringEngineeringKubernetesCostFinOpshttps://rajithattapattu.com/writing/kubernetes-cost-management-finops-practice/https://rajithattapattu.com/writing/kubernetes-cost-management-finops-practice/Once you can find optimization opportunities, human attention becomes the bottleneck. This piece applies the Crawl, Walk, Run maturity model to Kubernetes and looks at where SRE Agents fit.Sat, 05 Sep 2026 00:00:00 GMTEngineeringEngineeringKubernetesCostFinOpsAI for SREhttps://rajithattapattu.com/writing/kubernetes-cost-management-continuous-optimization/https://rajithattapattu.com/writing/kubernetes-cost-management-continuous-optimization/Kubernetes cost optimization fails when it is treated as a one-time cleanup.

Which one depends on the team you already have.Fri, 23 Jun 2023 00:00:00 GMTCompany BuildingCompany BuildingKubernetesStartups
