A Guide to Effective Dashboard Design for DevOps and SRE

Distributed tracing is crucial for monitoring complex systems. This article covers the three most popular open-source tracing tools: Jaeger, Zipkin, and Grafana Tempo.

Fundamentally, Dagger is a really awesome set of language bindings on top of buildkit – the library that tools like docker and buildah use to build container images. What is this means is that there is an easy way to build code in an isolated fashion with great caching, easy to write parallelism, remote execution, ability to spin up on-demand side car services, and portable abstractions.

Start running Terraform with cost estimation, security alerts, drift detection, access controls, and OPA policy testing. All within GitHub's UI.

Terrap - a powerful CLI tool that scans your infrastructure and identifies any required changes.

This repo includes prescriptive workflows that implement best practices when interacting with Terraform Cloud. These starter workflow templates provide a entrypoint to integrate your CI/CD pipelines with Terraform Cloud.

TLDR; Need a cluster up and running fast? Take a close look at eks-blueprints, I got started in minutes and have been working with it for almost 2 years now.

My team at Zendesk look after around 30 Kubernetes clusters. These are all self managed, meaning we maintain the API servers, and as you may guess: etcd.

Recently, I had a task to do some performance analysis on our etcd clusters. It had been a while since we ran any sort of benchmarking. Plus I wanted to get my hands dirty as I haven’t got much experience in tuning databases.

While I ended up getting about a 30% increase in performance, I learnt a lot about how databases, and by extension; how disks work together.

CoreDNS is a DNS add-on for Kubernetes environments. It is one of the components running in the control plane nodes, and having it fully operational and responsive is key for the proper functioning of Kubernetes clusters. Learning how to monitor CoreDNS, and what its most important metrics are, is a must for operations teams.

We’ve all done it — deleted a graph from a dashboard, realised we still need it but have forgotten the query. Use Terraform to go back in time and save yourself the headache

The greatest irony is that DevOps aimed to help developers talk with operations, and vice versa, yet developers are even further away from understanding how their code operates at runtime.
