We are very excited to announce Calico v3.7. Here are some highlights from the release.

When you’re working with EC2 or containers, VPCs have long been viewed as a must-have. Without them, you will face a constant barrage of attacks aimed at your infrastructure and OS, such as brute force login attacks. But are VPCs still needed when it comes to AWS Lambda? What do you actually get when you put a function inside a VPC? And what are the downsides?

Istio is a hot technology right now. Giants such as Google and IBM have devoted entire teams of engineers to the project to push it to production readiness. Since 1.0 has been released recently, I wanted to write down some of the things that confused me coming from a strictly Kubernetes only world where we have Ingress controllers and Service load balancers and how Istio takes these same concepts but on stimulants.

Docker Compose is a great tool to develop your Ruby on Rails application locally. It allows you to easily isolate your ruby environment, database, and even Redis if you use something like Sidekiq.

Writing Go applications in an isolated environment with Docker comes with some great advantages. You get a clean GOPATH, the bare essentials for developing, and you can easily change which Go version you’re developing against. In this quick tutorial, we’re going to show you how to structure a Go application with Docker Compose as your development environment.

FireHydrant.io has a changelog feature with a Kubernetes integration. Building this integration was challenging because the knowledge about creating an event oriented system with the Kubernetes client-go project was not as easy to understand as I would have hoped.

How many recipes do you have in your cookbook? This isn’t off topic, for today I’ll be exploring the ins and outs of Chef logging to help you maintain the state of your kitchen. (Last of the bad puns.) For those unfamiliar, Chef is a configuration management and platform automation tool that sits in the same space as Puppet (which we wrote about previously).

We’re on the verge of something here, people. A growing number of companies are shipping software in minutes. Yeah, you read that right. Minutes. Not hours, not weeks, months, or longer. Minutes. Often, teams struggle to ship software into the customer’s hands due to lack of consistency and excessive manual labor. Continuous integration (CI) and continuous delivery (CD) deliver software to a production environment with speed, safety, and reliability.
