Welcome to the StorageMinute series where we deliver key topics via bite-size content. In this edition, we will demonstrate how Stretched Clusters powered by vSAN deliver on-premises levels of availability and resiliency within the AWS cloud.

 

 

One of the primary inhibitors to leveraging public cloud as an extension of existing infrastructure is the need to rethink and at times rearchitect applications to account for cloud failure semantics.  Amazon commonly refers to this process as The 6 R’s. Stretched Clusters within the VMware Cloud on AWS service remove this complex and time-consuming process by providing on-premises levels of availability and resiliency inside the AWS cloud.

 

 

How does it work?

 

This powerful capability is powered by vSAN Stretched Cluster technology. Which enables a single vSphere Cluster to span multiple AWS availability zones. This dramatically reduces the complexity of public cloud by removing the need to undergo costly Refactoring or Replatforming activities.  By leveraging Stretched Clusters, customers can rehost their existing vSphere infrastructure directly inside the AWS fleet; using policy-based management to control what data is being synchronously replicated between availability zones.  With a copy of the data in each AZ, vSphere HA is empowered to recover from any failure using a simple restart. In summary, Stretched Clusters simplify the cloud by providing the same trusted controls and capabilities in addition to the scale and flexibility of the AWS infrastructure.
