Today I want to talk about metric queries. More specifically, I want to talk about an important concept that is going to make your queries run faster, give you more accurate results, and make your Grafana Loki operators (like me) much happier.

Maximize Your Serverless Success with the Complete AWS Lambda Monitoring Guide

etcdadm is a command-line tool for operating an etcd cluster. It makes it easy to create a new cluster, add a member to, or remove a member from an existing cluster. Its user experience is inspired by kubeadm.

Launchpad is a command-line tool that lets you easily create applications on Kubernetes.

In practice, Launchpad works similar to Heroku or Vercel, except everything is on Kubernetes.

In this post, we describe the motivation, advantages, and development of ClickHouse Keeper and preview our next planned improvements. Moreover, we introduce a reusable benchmark suite, which allows us to simulate and benchmark typical ClickHouse Keeper usage patterns easily. Based on this, we present benchmark results highlighting that ClickHouse Keeper uses up to 46 times less memory than ZooKeeper ​​for the same volume of data while maintaining performance close to ZooKeeper.

A modern way to building a complete workflow from Local to Production, with Skaffold and Gitlab on a Kubernetes cluster, to reduce cognitive load and operational complexity in application stacks.

Run kubectl commands in all/some contexts in parallel (similar to GNU xargs+parallel)

Etcd-backup-restore is collection of components to backup and restore the etcd. It also, provides the ability to validate the data directory, so that we could know the data directory is in good shape to bootstrap etcd successfully.

Deploy DynamoDB and a client app using cdk8s along with AWS Controller for Kubernetes

In this benchmark we compared initialization time across 8 managed Kubernetes providers.

Kubernetes v1.25 introduced Container Checkpointing API as an alpha feature. This provides a way to backup-and-restore containers running in Pods, without ever stopping them.

This feature is primarily aimed at forensic analysis, but general backup-and-restore is something any Kubernetes user can take advantage of.

So, let's take a look at this brand-new feature and see how we can enable it in our clusters and leverage it for backup-and-restore or forensic analysis.

eBPF-based auto-instrumentation of HTTP/HTTPS/GRPC Go services, as well as HTTP/HTTPS services written in other languages (intercepting Kernel-level socket operations as well as OpenSSL invocations).
