70% cheaper Kubernetes cluster on AWS
We are running Kubernetes on both sandbox and production for some months now.
Our production cluster is still small, with few services running on it, but,
most of our sandbox environment is running on a Kubernetes cluster on AWS.
Writing cli applications with Golang
Last few months I’ve been using Go to write quite a lot of tools. In this post
I intent to show not why I chose Go over others, but how I architect
those tools, what libraries I use and what kind of automation I have in place.
Measuring production code coverage with JaCoCo
Microservices is the new fancy way of doing applications. Yet, most
companies still have big and old monoliths in production. In fast evolving
software of this size, it’s usual to have lines of code which are never
executed in production. Production code coverage reports can help
us find those lines.
From Travis Enterprise to BuildKite in 50 repositories
At ContaAzul, we use the CI infrastructure a lot. We open
several pull requests in several projects every day, and we block the merge
until the build pass. We consider our
master branches are sacred, and
we can’t afford too much waiting to change them.
Distributed Locking with Redis
At ContaAzul, we have several old pieces of code that are still running
in production. We are committed to gradually re-implement them in better ways.
