CoreDNS is a DNS server that can also provide service discovery for microservice-based applications. It’s the default DNS server in Kubernetes, providing name resolution and service discovery for the services operating in the cluster. CoreDNS is easily customizable, so you can define how it should act on each request beyond simply executing a DNS lookup.

Containers, along with containerization technology like Docker and Kubernetes, have become increasingly common components in many developers’ toolkits. The goal of containerization, at its core, is to offer a better way to create, package, and deploy software across different environments in a predictable and easy-to-manage way.

One of the many challenges when building an application is ensuring that it's secure. Whether you're storing hashed passwords, sanitizing user inputs, or even just constantly updating package dependencies to the latest and greatest, the effort to attain a secure application is never-ending. And even though containerization has made it easier to ship better software faster, there are still plenty of considerations to take when securing your infrastructure as well.

We’ve all been in the situation where suddenly you are the lone developer on call while everyone is out of pocket. Or in the case of Grafana Labs Director of UX David Kaltschmidt, his then business partner, Grafana Labs VP of Product Tom Wilkie, was checking out for a weekend music fest. “Tom and I founded a company a couple of years ago, and I’m more of a frontend person. Tom did all the backend and devops stuff,” explained Kaltschimdt.

Congratulations Twistlock! One of the best signs of an emerging market is when existing, massive players are willing to put hundreds of millions of dollars on the line to get into that market right now. Given today’s Twistlock acquisition by Palo Alto Networks, and other recent acquisitions like Heptio/VMware, we believe this is happening in the cloud-native market. Congratulations to Twistlock on their success.
