- 1. 1 Kubernetes on Google Cloud Platform ●Use with Preemptible VMs, custom machine types, GPUs ● Live migration and patching ● Best-in-class networking ● Sustained use discounts, committed use discounts, and per-second billing mean you only pay for what you use ● Integration with Google Cloud Platform services such as BigQuery, PubSub, Cloud SQL, and more

- 4. 4 Node Pools A nodepool is a group of nodes that have the same configuration Node pools run in the customer’s project Can configure one or multiple node pools per cluster Allows you to mix-and-match machine configurations (e.g., local SSDs, preemptible VMs, specific node images, larger instance sizes) Controlled by Managed Instance Groups under the hood Google Kubernetes Engine Kubernetes Control Plane Node-pool-n, us-central1-a Node Node Node Node

Editor's Notes
- #2 But let’s pause a second and talk what do you get when you set up a Kubernetes engine cluster? So the whole process takes 3 minutes on average, you click a button and 3 minutes later you get your cluster,
- #3 Fully managed = we take care of backups and repairing the master if problems occur Once you click create cluster, Google creates a hosted control plane for your cluster. For those of you familiar with Kubernetes, it is largely the same as every other Kubernetes deployment but in this case we manage the control plane components and provide a black-box API endpoint to the user. The main benefit is not the cluster deployment but how we manage it for you. We make sure it is available through monitoring, health checks and auto repairs. We are responsible for daily backups. We keep you up to date, and upgrade your control plane to the latest Kubernetes version available in a reliable manner. So this is one less thing to worry about.
