Disaster Recovery as a Service(DRaaS)

Disaster recovery as a service(DRaaS) is a cloud computing service model that allows an organization to back up its data and IT infrastructure in a third-party cloud computing environment and provide all the DR orchestration, all through a SaaS solution, to regain access and functionality to IT infrastructure after a disaster. Disaster recovery planning is critical to business continuity. Many disasters that have the potential to wreak havoc on an IT organization have become more frequent in recent years: -
* Natural disasters such as hurricanes, floods, wildfires, and earthquakes
* Equipment failures and power outages
* Cyberattacks

How does DRaaS work?

DRaaS works by replicating and hosting servers in a third-party vendor’s facilities versus in the physical location of the organization that owns the workload. The disaster recovery plan is executed on the third-party vendor’s facilities in the event of a disaster that shuts down a customer’s site. Organizations may purchase DRaaS plans through a traditional subscription model or a pay-per-use model that allows them to pay only when disaster strikes. As-a-service solutions vary in scope and cost—organizations should evaluate potential DRaaS providers according to their own unique needs and budget.

Benefits

DRaaS is especially useful for small-to-medium (SMB) sized businesses. For the SMB, DR often just consists of doing daily backups and storing the backup media offsite – which covers the basics but makes for poor Recovery Point and Time Objects (RPOs and RTOs). DRaaS is affordable because it allows businesses to forgo the need for a second physical site. With DRaaS, the cloud can be your DR site. Plus, you only pay for the infrastructure in the cloud that you use. Storing backups or VM images is far less expensive than running them.
