Data resiliency is all about ensuring that data is always readily available, regardless of status or disruptions.

In essence, an organization can recover its workload from disruptions or mitigate them. For an organization to retain good data resiliency, they must understand what sort of disruptions their application can experience and how broad of an impact these disruptions can have as well, with solutions varying depending on whether the data is in the cloud, on-prem or both.

“The big contrast in the cloud comes with how we think about capacity,” said Ashish Palekar (pictured, left), general manager of EBS Snapshots and EBS Edge at Amazon Web Services Inc. “The infrastructure complexity and the cost associated with that are also just a function of how infrastructure is built in the cloud. But all that starts with the bedrock of how we design for avoiding single points of failure.”

Palekar and Cami Tavares (pictured, right), head of product, Elastic Block Store at AWS, spoke with theCUBE industry analyst Dave Vellante at AWS Storage Day, during an exclusive broadcast on theCUBE, SiliconANGLE Media’s livestreaming studio. They discussed the core pillars of data resiliency, the importance of snapshots, what action organizations can take to improve resiliency and more. (* Disclosure below.)

Resiliency through preparedness

EBS is a large distributed system with many components that are built with resiliency in mind, according to Tavares. This allows all components to operate and fail independently. Snapshots are a core pillar of resiliency in EBS, enabling organizations to restore volume from a point in time.

“Snapshots are actually a regional service. That means, internally, we use multiple Availability Zones … to replicate your data so that the snapshots can withstand the failure of an Availability Zone,” Tavares said. “Thanks to that Availability Zone independence … customers can use that snapshot and recreate an EBS … even in another region if they need to. “

The conversation closed with the trio discussing what methods organizations can adopt to build more resilience into their applications with minimal anxiety.

“We recommend that customers take the snapshots at least daily. And we have features that make that easier for you,” Tavares  said. “And then the other pillar we talked to customers about is data replication. Just another very important step when you’re thinking about your resiliency and your recovery plans.”
