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. This makes it possible to regain access and functionality to IT infrastructure after a disaster. The as-a-service model means that the organization itself doesn’t have to own all the resources or handle all the management for disaster recovery, instead relying on the service provider.
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
True DRaaS mirrors a complete infrastructure in fail-safe mode on virtual servers, including compute, storage and networking functions. With our services, TSI can help organizations continue to run applications—it just runs them from the service provider’s cloud or hybrid cloud environment instead of from the disaster-affected physical servers. This means recovery time after a disaster can be much faster, or even instantaneous. Once the physical servers are recovered or replaced, the processing and data is migrated back onto them. Customers may experience higher latency when their applications are running from the cloud instead of from an on-site server, but it’s better than nothing running at all.
