VAST on Cloud enables you to spin up virtual VAST Clusters as ephemeral or persistent cloud resources on a permanent or on-demand basis. It is ideal for providing a wide range of data services in the cloud for both permanent and short-term jobs. With VAST on Cloud, you get access to enterprise-class, high-performance File, Object, and Database capabilities, benefitting from the powerful VAST data reduction capabilities. When needed, you can leverage the VAST DataSpace to transfer data between your cloud and on-prem clusters.
We recommend using the global snapshot clone feature to instantly replicate data from your on-premises cluster to a VAST on Cloud cluster, and to use async replication to periodically replicate your output to your on-premises cluster. This makes the data instantly available for your workloads. Follow the sections below to create a VAST on Cloud cluster and start working.
Once your cluster is installed in the cloud, you can use a global snapshot clone with background sync to fully copy the data to the cloud, or without background sync in which case only the metadata is copied and data is read from the source on demand. You can alternatively replicate the data using VAST async replication. The method described below uses a global snapshot clone with or without background sync.
Limitations
VAST on Cloud clusters do not support expansion or OS upgrade.
Ongoing changes on a data path that you cloned using a global snapshot clone are not synced with the VAST on Cloud cluster. The data you work with is sourced from the specific snapshot that you clone.
