We’re excited to announce Microsoft Azure support for the Kubernetes auto scaling module, an open source system
for automating deployment, scaling, and management of containerized applications. This feature, now available on
the Kubernetes GitHub repository, provides fully-automated integration with Azure.
Auto scaling is an important feature that enables users to maintain application availability while scaling their
Azure capacity up or down as needed to meet spikes in demand. The release marks a step-forward in our commitment
to support integration and production-ready modules in the cloud.
Automatically Integrate Auto Scaling to Azure in Minutes
Until now, auto-scaling has only been available in Amazon Web Services (AWS) and Google Cloud environments. This
release provides now the same support for Microsoft Azure. The acceptance of this patch to the Kubernetes GitHub
repository marks EastBanc Technologies’ first contribution to the Kubernetes codebase open source project.
Auto Scale with Ease
As a software development firm with extensive experience in deploying Kubernetes, we have seen a surge in demand
for this capability from our clients. With this release, we’ve facilitated the deployment process of Kubernetes
on Azure platform. Users don’t need to make an investment in costly developers to take advantage of this
solution. We’ve made it easy. Just a few clicks and you can get it up and running – the solution takes care of
the integration automatically. The feature will be available as part of Kubernetes soon, but can be experienced
How it Works
The auto scaler module automatically adjusts the size of the Kubernetes cluster under specific conditions and
provides the ability to both scale-up and scale-down operations. Scaling-up occurs when a specific pod lacks the
resources (CPU or RAM) to run in the cluster. While scaling-down occurs when certain nodes in the cluster are
underutilized for a prolonged period of time, these nodes are deleted and their pods placed on existing nodes
instead. Full documentation on the cluster auto scaler is available on GitHub.
To get started you’ll need to set-up a scalable Kubernetes cluster using Azure Virtual Machine Scale Sets for
node groups. Currently, Kubernetes setup in Azure VMSS is only supported by kube-up.sh, which is included in
Kubernetes distribution. You may encounter certain Azure limitations issues with Kubernetes in such a set-up due
to limitations with Azure, read more here and here. While Azure support is currently limited, the Kubernetes
team is actively working on improving it, and you can still test Azure Auto-Scaler with the latest version of
Kubernetes. You may notice that the auto-scaler image used in the manifest, which includes the patch, is our
build. This will not necessarily be the case after the next official auto-scaler release.
