• When failover isn't safe: building high-availability PostgreSQL on Kubernetes

  Shree Sampath

  This case study shows how a Datadog gameday exposed unsafe PostgreSQL failover on Kubernetes and how they made it safe with synchronous replication and Patroni.

• An 8-minute outage from a dead NLB and a JVM that cached DNS forever

  claire nguyen

• Load Testing Apollo Router

  Yurii Rochniak

  This case study shows how Preply tested Apollo Router with a Rust mock service and Vegeta, found a safe range of 1,200–1,500 requests per second, and chose CPU-based autoscaling.

• Your KV Cache Transfer Is 100x Slower Than It Should Be

  Federico Iezzi

  This case study finds a 100x KV cache transfer slowdown in vLLM on GKE, shows how NixlPushConnector restores about 49 GB/s, and measures the latency tradeoff of disaggregated LLM serving.

More articles

• The missing control plane above vLLM

  Waleed Malik

  This article argues that vLLM in a pod is only the engine, and maps the layers a real LLM platform needs around it:

  • tenant keys and budgets,
  • inference-aware routing,
  • and GPU scheduling.
• Investigating High Memory Utilization in a WSO2 API Manager Deployment

  Dilky Liyanage

  This article explains why a JVM pod can sit at 90% memory and still be perfectly healthy, and how to compare pod memory with real heap usage before hunting for a leak.

• Building a Raspberry Pi Datacenter at Home

  Niki Dokovski

  This article shows how a twelve-board Raspberry Pi lab is put together, from cloud-init provisioning and static networking to a Ceph storage tier and a Kubernetes cluster sitting on top.

• I benchmarked 5 Languages in Kubernetes and here is what your stack actually costs

  Ashok Vishwakarma

  This article benchmarks Go, Node.js, C#, Java and Python on the same Kubernetes cluster and shows how image size and startup time drive scaling speed and turn language choice into a monthly bill.
