Google expands its container service with GKE Advanced
With its Kubernetes Engine (GKE), Google Cloud has long offered a managed service for running containers on its platform. Kubernetes users tend to have a variety of needs, but so far, Google only offered a single tier of GKE that wasn’t necessarily geared toward the high-end enterprise users the company is trying to woo. Today, however, the company announced a new advanced edition of GKE that introduces a number of new features and an enhanced financially backed SLA, additional security tools and new automation features. You can think of GKE Advanced as the enterprise version of GKE.
The new service will launch in the second quarter of the year and hasn’t yet announced pricing. The regular version of GKE is now called GKE Standard.
Google says the service builds upon the company’s own learnings from running a complex container infrastructure internally for years.
For enterprise customers, the financially backed SLA is surely a nice bonus. The promise here is 99.95 percent guaranteed availability for regional clusters.
Most users who opt for a managed Kubernetes environment do so because they don’t want to deal with the hassle of managing these clusters themselves. With GKE Standard, there’s still some work to be done with regard to scaling the clusters. Because of this, GKE Advanced includes a Vertical Pod Autoscaler that keeps on eye on resource utilization and adjusts it as necessary, as well as Node Auto Provisioning, an enhanced version of cluster autoscaling in GKE Standard.
In addition to these new GKE Advanced features, Google is adding GKE security features like the GKE Sandbox, which is currently in beta and will come exclusively to GKE Advanced once it’s launched, and the ability to enforce that only signed and verified images are used in the container environment.
The Sandbox uses Google’s gVisor container sandbox runtime. With this, every sandbox gets its own user-space kernel, adding an additional layer of security. With Binary Authorization, GKE Advanced users also can ensure that all container images are signed by a trusted authority before they are put into production. Somebody could theoretically still smuggle malicious code into the containers, but this process, which enforces standard container release practices, for example, should ensure that only authorized containers can run in the environment.
GKE Advanced also includes support for GKE usage metering, which allows companies to keep tabs on who is using a GKE cluster and charge them according. This feature, too, will be exclusive to GKE Advanced.
