If you’re running a Kubernetes cluster on Azure, you’re going to want to read this post.
Today, we’re going to cover everything you need to know about AKS system node pools. What are they? How do they work? When should you use them? We’ll answer all of those questions and more. So let’s get started!
An AKS system node pool is a special type of node pool that’s used to manage critical system components in your Kubernetes cluster. System node pools are designed to be highly available and durable, so they can withstand failures and keep your applications running.
System Node Pools
System node pools are different from regular node pools in a few key ways:
– First, system node pools are managed by Azure AKS. This means that they’re automatically kept up to date with the latest security updates and features.
– Second, system nodes in a pool are tightly clustered together. This provides high availability and ensures that your applications can always run even if one or more nodes go down.
– Finally, system node pools are always deployed in a separate subnet from your regular nodes. This ensures that they can’t be impacted by network issues or outages that might affect your other nodes.
Now that we’ve covered the basics of AKS system node pools, let’s talk about when you should use them. AKS system node pools are a great choice for applications that require high availability and can’t afford to have any downtime. They’re also a good choice for applications that need to be highly scalable, as the tightly clustered nodes make it easy to add more nodes to the pool as needed.
So there you have it! Everything you need to know about AKS system nodes.
