Figure 2 shows the four strategies for DR that are highlighted in the DR whitepaper. All requests are now switched to be routed there in a process called “failover.” For tighter RTO/RPO objectives, the data is maintained live, and the infrastructure is fully or partially deployed in the recovery site before failover.
Easily perform failover and backup testing quickly, without disruption. Whitepaper. Lower risk with instant, non-disruptive testing. Test often, test anytime. Zerto allows you to take the guesswork and risk out of the process with instant, non-disruptive testing. Get out of ransomware jail and try the Zerto Free Edition. Sophos Ltd.
Application-consistent points in time will be indicated as a checkpoint in the Zerto journal of changes to ensure visibility when performing a move, failover, or failover test in Zerto. Read the full whitepaper on Protecting Oracle databases on VMware with Zerto.
The Availability and Beyond whitepaper discusses the concept of static stability for improving resilience. What if the very tools that we rely on for failover are themselves impacted by a DR event? Failover plan dependencies and considerations. Relying on an automated health check to control Regional failover can be tricky.
Perform an entire site or application failover, failback, and move without data loss or impact to production. Also, read our technical comparison whitepaper on Zerto vs. traditional periodic backup technology. This all happens from a local journal on the production site. See links below: Zerto Free On-Demand Labs.
Check out the IDC whitepaper The State of Ransomware and Disaster Preparedness. In the event of an outage due to a ransomware attack completely taking your primary site down, Zerto for Kubernetes helps users fight back by performing a failover live operation. The Zerto for Kubernetes failover test workflow can help check that box.
This architecture pattern follows the option of the “Multi-Account Decentralized” model as described in the whitepaper Hybrid Cloud DNS options for Amazon VPC. Failover routing policy is set up in the PHZ and failover records are created. This architecture involves three key components: 1. Considerations.
By using the best practices provided in the AWS Well-Architected Reliability Pillar whitepaper to design your DR strategy, your workloads can remain available despite disaster events such as natural disasters, technical failures, or human actions. Failover and cross-Region recovery with a multi-Region backup and restore strategy.
The left AWS Region is the primary Region that is active, and the right Region is the recovery Region that is passive before failover. When a disaster occurs, successful recovery depends on detection of the disaster event, restoration of the workload in the recovery Region, and failover to send traffic to the recovery Region.
With a multi-Region active/active strategy, if your workload cannot operate in a Region, failover will route traffic away from the impacted Region to healthy Region(s). Alternatively, you can use AWS Global Accelerator for routing and failover. Disaster recovery options in the cloud whitepaper. It does not rely on DNS.
Minimum business continuity for failover. To meet these goals, we developed a long-term business continuity plan per the Disaster Recovery of Workloads on AWS: Recovery in the Cloud whitepaper that consisted of the following: We accepted data loss for the data that’s not persistent in the database.
