Most of us already aware about few Disasters recovery solution like SRM, vSphere replication and Zerto to Protect workload (VM's) from Primary Datacenter to Secondary Datacenter.
In these Blog, I want to discuss one of new service launched by VMware for Disaster recovery to protect workload (VM's) between On-Prem Datacenter to VMware Cloud on AWS,which is called as VMware Cloud Disaster Recovery.
VMware Cloud Disaster Recovery (commonly called VMware Cloud DR or VCDR) to protect your vSphere virtual machines (VMs) by replicating them to the cloud and recovering them as needed to a target VMware Cloud Software Defined Data Center (SDDC) on VMware Cloud on AWS.
Service Component in VCDR
1.Cloud Based File System :A cloud component that enables the efficient storage of backups of protected VMs in cloud storage and allows VMs to be recovered quickly, without requiring data rehydration.
2.Orchestrator : This service will provide to automate the disaster recovery process .
3.DRaaS connector : This is virtual appliance which will help to protect VMs using snapshot replication from protection groups.
4.Protection Groups : Protection group where you keep your virtual machine which you want to protect and create regularly scheduled snapshots of VMs which replicate to the cloud file system.
5.Disaster Recovery (DR) Plans : Here you can define the steps required to recover the workload from cloud-based file system to recovery SDDC on VMware cloud on AWS .
In below scetion you can see the component which i explain above and how DRaaS connector connected with SaaS Orchestrator and Cloud based Filed system to protect workload (VMs) .
Now, Let's understand difference between Protected Site ,Recovery Site and Backup Site.
1.Protected Site : Protected Site is where your virtual machine is running primary and which you want to protect and recover on Recovery (Secondary Site ) in case if Disaster hit or any planned activity.
2.Backup Site: Backup Site is Cloud backup where the workload (VMs) is replicated and saved.You can deploy additional backup site also. In case of Disaster or planned activity cloud-based file system on Backup site mount with recovery SDDC as NFS storage recover your VMs.
3.Recovery Site : Recovery Site is where you will recover workload (VMs) during failover action.It comes with two subscription model 1. On-demand 2. Pilot Light.
A) On-Demand : Here, as name already explained that you can deploy SDDC on VMware Cloud on AWS during failover or disaster. It is not Pre-Deployed SDDC on recovery site. Its On-Demand SDDC infrastructure which you can deploy whenever its required .
B ) Pilot Light: Pilot light you can also called pre-deloyed deployment .Its deployed with smaller subset of SDDC hosts to be deployed ahead of time for recovering critical application .
