Disaster Recovery (DR) Architecture on AWS, Part I: Strategies for Recovery in the Cloud

AWS Disaster Recovery

Active/passive and active/active DR strategies. Active/passive DR. Figure 2 categorizes DR strategies as either active/passive or active/active. In Figure 3, we show how active/passive works. All requests are now switched to be routed there in a process called “failover.”

The Storage Architecture Spectrum: Why “Shared-nothing” Means Nothing

Pure Storage

I use these examples to illustrate the huge difference between a simple active-passive database running on two servers and a scalable cloud-native database that gets lost when you describe a system merely as “shared-nothing.” And with Pure Storage’s shared-NVRAM approach, this makes controller failover events completely non-disruptive.

Delivering Multicloud Agility with Software-defined Storage

Pure Storage

In the cloud, everything is thick provisioned and you pay separately for capacity and performance. Controller 1 is actively using those resources while controller 2 is in a standby configuration. You can update the software on controller 2, then failover so that it’s active.
