Kubernetes and the many projects under the Cloud Native Computing Foundation (CNCF) umbrella are advancing so quickly that it can sometimes feel as though the benefits of the open hybrid cloud are, perhaps, not yet evenly distributed. While systems administrators and operators are having a blast modernizing legacy applications and automating highly-scalable, container-based systems, sometimes developers can feel a bit left out in the cold.

That’s because there’s a disconnect between the velocity increase that IT is experiencing through the adoption of containers, and the agility increase offered to developers. The benefits that Kubernetes offers to IT operators are in service of simplifying the lives of their developers. Developers and IT administrators want different things, right? Or do they?

Back in 2016 when I was at CoreOS, we saw this disconnect beginning to form. We worried that while enabling developers was job one for IT, it wasn’t necessarily easy when developers had to relearn their entire stacks from the ground up in order to adopt containers. It was also tough for IT administrators to provision compliant, governed services at the pace expected in cloud development.

To fix this, CoreOS introduced the concept of Kubernetes Operators. Soon after, we produced a set of tools known as the Operator Framework to help users build, ship and discover their own Kubernetes Operators. While a lot has changed for myself and CoreOS since 2016, most notably the fact that we are now both a part of the Red Hat family, Operators remain an important part of our strategy for helping developers and administrators focus on using Kubernetes — rather than tweaking its various knobs and configurations.

Naturally, all of the work on Operators was done as open source, and as a result we recently contributed the Operators Framework to the CNCF, to become an incubated project. We did this for a few reasons, including that it was the right thing to do in this open ecosystem. But we also did it so that Operators will become a ubiquitous path to distributing servers into Kubernetes clusters. With Operators available to every Kubernetes distribution, the entire open hybrid cloud ecosystem will benefit from greater compatibility, simplicity and easier management.

Operators are a big part of helping us reach this automated, on-demand, container-based future. Operators are operational procedures and best practices that are codified into software. They make automated day two operations possible on Kubernetes, and model the complexities of today’s distributed systems.

For example, there isn’t a concept of data rebalancing in Kubernetes, but that can be built on top of the Kubernetes APIs with the Operator Framework. These types of applications are required for running what we call the third wave of applications on Kubernetes: complex distributed systems.
