Over time, a system collects state on its root partition. This state lives in assorted directories like /etc and /var , and represents every under-documented or out-of-order step in bringing up the services.
The microservices honeymoon period is over. Uber is refactoring thousands of microservices into a more manageable solution [1]; Kelsey Hightower is predicting monoliths are the future [2]; and even Sam Newman is declaring that microservices should never be the default choice, but rather a last resort [3]. What’s going…
While Kubernetes has many advantages, it also brings new security challenges.
It has only been five years since Jeff wrote on this blog about the launch of the Amazon Elastic Container Service. I remember reading that post and thinking how exotic and unusual containers sounded. Fast forward just five years, and containers are an everyday part of most developers lives, but whilst customers are…
Deploys require a careful balance of speed and reliability. At Slack, we value quick iteration, fast feedback loops, and responsiveness to customer feedback. We also have hundreds of engineers who are trying to be as productive as possible. Keeping to these values while growing as a company means continual refinement…
Docker is pleased to announce that we have created a new open community to develop the Compose Specification.
Announcing Krustlet
The post analyzes how major cloud platforms are faring under pressure and usage spikes caused by COVID-19 during March 2020.
Just over a year ago, we founded Tailscale with a common sense of nostalgia for the “good old days” of LANs. In our collective opinion (then and now) networking and cloud infrastructure has become too complicated. Attempts to increase team connectivity and migrate towards remote work results in a corresponding burden…
Grafana is an open source visualization and dashboarding technology that allows you to explore your metrics, logs, and traces no matter where the data is.
The twit was followed by a very productive discussion, with many nice people trying to figure out even better ways to spend money on AWS. As an Azure user, I felt sad and left out, so I decided to fix this injustice. If you are in quarantine and you have insane amounts of money to spend, I got you covered: you only…
We're pleased to announce the delivery of Kubernetes 1.18, our first release of 2020! Kubernetes 1.18 consists of 38 enhancements: 15 enhancements are moving to stable, 11 enhancements in beta, and 12 enhancements in alpha. Kubernetes 1.18 is a "fit and finish" release. Significant work has gone into improving beta…
This article walks through the technical and cultural reasons why Facebook is not in the cloud business, and whether it will be in the future.
TL;DR: I set up Minikube on an old (2012) MacBook Air and configured it to be able to connect from outside my home network so I would have an always-on Kubernetes cluster at home to experiment with.
Understand the entire Tailscale system, how it works, how we built it, and its benefits compared to legacy VPNs. Use this article as a guide to quickly build your own Tailscale replacement.
1 I usually rely on Minikube , though other solutions exist, like Kind , that can actually emulate multiple nodes. Multi-node support may eventually come for Minikube. A year ago, I decided I would build my own Kubernetes cluster. As a software engineer, I either use a local single-node Kubernetes cluster 1 , or a…

See a real-world example of how Google’s SRE practices can identify and help fix issues, even at the bottom of the hardware stack.
AI Platform Pipelines provides enterprise-ready infrastructure for deploying and running structured ML workflows, and pipeline tools for building, debugging, and sharing pipelines and components.
Learn to predict how your application will behave in times of failure and how to configure every parameter for your Semian circuit breaker.
TL;DR: Azure and Digital Ocean don't charge for the compute resources used for the control plane, making AKS and DO the cheapest for running many, smaller clusters. For running fewer, larger clusters GKE is the most affordable option. Also, running on spot/preemptible/low-priority nodes or long-term committed nodes…
For smaller teams, Kubernetes is usually the wrong solution: too complex, too complicated, and with too much work to keep it running.
The Strangler is an extremely effective technique for phasing out legacy systems over time. Instead of spending months getting a new system up to parity with the current system so that clients can…
A little over a year ago, my employer threw away our VPNs in production and production-like server environments and moved towards a set of new, cutting-edge technologies that make remote access sim…
