"When it became clear that Google Kubernetes Engine was going to have a lot of support from Google and be a fully-managed Kubernetes platform, it seemed very obvious to us that was the way to go," says Eynon-Lynch.

<p>Recently, the team launched a new single sign-on solution for use in an internal application. "Due to the resource based architecture of the Kubernetes platform, we were able to bring that application into an entirely new production environment in less than a day, most of that time used for testing after applying the already well-known resource definitions from staging to the new environment," says van den Bosch. "On a traditional VM this would have likely cost a day or two, and then probably a few weeks to iron out the kinks in our provisioning scripts as we apply updates."</p> <p>Recently, the team launched a new single sign-on solution for use in an internal application.

<p>Legacy applications are also being moved to Kubernetes. Not long ago, the team needed to set up a Java-based application for compiling and running a frontend. "On a traditional VM, it would have taken quite a bit of time to set it up and keep it up to date, not to mention maintenance for that setup down the line," says van den Bosch. Instead, it took less than half a day to Dockerize it and get it running on Kubernetes. "It was much easier, and we were able to save costs too because we didn't have to spin up new VMs specially for it."</p> <p>Legacy applications are also being moved to Kubernetes.

<p>In addition, Wink had other requirements: horizontal scalability, the ability to encrypt everything quickly, connections that could be easily brought back up if something went wrong.

<p>Once Wink's backend engineering team decided on a Dockerized workload, they had to make decisions about the OS and the container orchestration platform. "Obviously you can't just start the containers and hope everything goes well," Klein says with a laugh. "You need to have a system that is helpful [in order] to manage where the workloads are being distributed out to. And when the container inevitably dies or something like that, to restart it, you have a load balancer. All sorts of housekeeping work is needed to have a robust infrastructure."</p> <p>Once Wink's backend engineering team decided on a containerized workload, they had to make decisions about the OS and the container orchestration platform.

<p>Wink considered building directly on a general purpose Linux distro like Ubuntu (which would have required installing tools to run a containerized workload) and cluster management systems like Mesos (which was targeted toward enterprises with larger teams/workloads), but ultimately set their sights on CoreOS Container Linux. "A container-optimized Linux distribution system was exactly what we needed," he says. "We didn't have to futz around with trying to take something like a Linux distro and install everything. It's got a built-in container orchestration system, which is Fleet, and an easy-to-use API. It's not as feature-rich as some of the heavier solutions, but we realized that, at that moment, it was exactly what we needed."</p> <p>Wink considered building directly on a general purpose Linux distro like Ubuntu (which would have required installing tools to run a containerized workload) and cluster management systems like Mesos (which was targeted toward enterprises with larger teams/workloads), but ultimately set their sights on CoreOS Container Linux.

<p>Wink's hub (along with a revamped app) was introduced in July 2014 with a short-term deployment, and within the first month, they had moved the service to the Dockerized CoreOS deployment.

<p>Using this setup did require some customization. "Fleet is really nice as a basic container orchestration system, but it doesn't take care of routing, sharing configurations, secrets, et cetera, among instances of a service," Klein says. "All of those layers of functionality can be implemented, of course, but if you don't want to spend a lot of time writing unit files manually – which of course nobody does – you need to create a tool to automate some of that, which we did."</p> <p>Using this setup did require some customization.
