New Upgrades & Visible Improvements2021-01-29

  • We upgraded Kubernetes to version 1.19 and bumped Cilium up to version 1.9. Take it for a spin here.
  • If you’re creating a new cluster with Azure as one of the providers, it will now use non-burstable Azure instance types.
  • Get more control if you see the need: interrupt and add a Spot Instance Node right from your Node list.
  • And, as always, we've shipped some bug-fixes and performance improvements.

CAST AI welcomes the beloved Developer Cloud!2021-01-22

  • You asked, we've delivered: DigitalOcean is now part of our ever-growing list of supported cloud service providers. Starting now, you can stretch your Kubernetes clusters across DO, AWS, GCP and Azure. Sign up here !

Support for Spot/Preemptive Instances added2021-01-22

  • Spot instances, if applied correctly, can yield up to 60-80% cloud savings and are really useful for stateless workloads (think, micro-services). So, starting now, if you want to, we can tell our optimization engine to start purchasing Spot (Preemptive on GCP) instances for you. And if these instances are interrupted by the cloud provider, we automatically replace them! GCP & Azure instances will follow very shortly. Read more in our documentation.
