The total number of machines fluctuates with autoscaling throughout the day, but is always at least many thousands, across ten AWS regions. Our entire production environment exists on AWS and currently nowhere else. What does Ably do instead?Ībly is a public cloud customer.
With namespaces, built-in resource management, as well as built-in virtual networking features, or services meshes, or both, it also allows deploying multiple interacting services maintained by different teams without stepping on each other’s feet. Developers are already comfortable with Docker, and Kubernetes makes it easy to get the same container running in production. The public cloud is where a major motivation comes in for many organizations deploying Kubernetes today: it is seen as a unifying API layer that makes multi-cloud deployments transparent for your DevOps people.Įven in a single cloud, the Kubernetes developer experience is commonly cited. Most Kubernetes deployments today seem to happen on virtual machines, most often on public cloud providers. Somewhat surprisingly, not a lot is left of the original purpose Kubernetes inherited from its inspiration, Borg – that being turning a large pool of baremetal machines into a private cloud environment. It has endless vendor support, and you don’t launch a software product these days without official Docker images and a Kubernetes deployment guide. It was developed by engineers with serious large scale production workload experience, applying real-world proven techniques from Google’s Borg orchestration system. Mesos is rapidly fading in popularity, the less said about Docker Swarm the better, and if you are still deploying to plain EC2 instances, you might as well be feeding punch cards. While dissenting voices exist, it is still very much at the peak of its hype cycle – it can frequently feel like everybody’s running on Kubernetes, or at the very least everyone is talking about how they want to move everything over to Kubernetes. Kubernetes is the most widely known system for large scale orchestration of containerized software. This is also a question we ask of ourselves when planning our longer term infrastructure road map: should we use Kubernetes as our primary deployment platform at some point? Why Kubernetes? We have even had interesting candidates walk away from job offers citing the fact that we don’t use Kubernetes as the reason! This has been asked by current and potential customers, by developers interested in our platform, and by candidates interviewing for roles at Ably. Like in most tech companies, this infrastructure is largely software-based also like in most tech companies, much of that software is deployed and runs in Docker containers.Īs you might expect if you’ve been following the technology scene at all, the following question comes up a lot: At Ably, we run a large scale production infrastructure that powers our customers’ real-time messaging applications around the world.
