How-to Video from Zerto – Protect Applications, Not Just Data. In virtualized environments, coordinating the state of the data and the state of the application is challenging. Especially for tier-1 applications, which typically span multiple virtual machines, application protection is not simple. Business-critical applications are more complex in terms of dependencies and infrastructure, have aggressive service-level agreements (SLAs), and require robust and effective recovery processes.
Application-centric Protection:
When a multi-tiered application such as SAP, Microsoft Exchange or an ERP instance has several virtual machines supporting it, those virtual machines can be located across disparate hosts and storage arrays, even different processor chip sets – making replication of the full application quite complex.
Zerto addresses an innovation called “Virtual Protection Groups (VPGs)” in the video below.
A VPG groups together a number of virtual machines, regardless of their physical location from a host or storage perspective, consistently replicating these VMs using a group-level policy. Typically, VPGs are organized by the virtual machines that comprise a multi-tiered application, however they can consist of a single VM or VMs grouped in whichever manner is best for the business.
The key is to insure write-order fidelity of the VPG, so that the data is kept in the same sequence as it was written at the originating source. Write-order fidelity is maintained for all of the VMs within a VPG, even if they are located on a different physical host. For more information on Virtual Protection Groups, you can download the white paper “Protecting Applications, Not Just Data”
