That's 93.6% faster median latency and near-perfect reliability compared to the standard approaches for scaling Node.js applications. These results come from production-grade benchmarks on real Next.js applications running on Kubernetes, comparing three common deployment strategies with identical total CPU resources (6 CPUs each). All configurations were tested under the same sustained load patter

The days of counting bits and clock ticks are history. CPU and memory may be cheap, but not enough to waste them â especially since it would be at our usersâ expense. In this blog post, Iâll explain how we run our services in Kubernetes and manage their resources, how to make the most of them and what to look out for.

stern Stern allows you to tail multiple pods on Kubernetes and multiple containers within the pod. Each result is color coded for quicker debugging. The query is a regular expression so the pod name can easily be filtered and you don't need to specify the exact id (for instance omitting the deployment id). If a pod is deleted it gets removed from tail and if a new pod is added it automatically get
