Disaster Recovery as a service (DRaaS) is a cloud computing model that enables an enterprise to back up its data and IT resources in a third-party cloud computing ecosystem while enabling DR orchestration— all through a SaaS solution. It is done to restore access and functionality to IT infrastructure after the disaster strikes.
The DRaaS model ensures the business itself does not have to own all the resources or handle the entire disaster recovery management.
What is the need for disaster management?
Disaster recovery planning is decisive to business continuity. Several crises that have the potential to wreak havoc on IT systems have become more prevalent in the modern world; These may include:
- Natural calamities such as floods, tsunamis, hurricanes, wildfires, and earthquakes
- Equipment breakdowns and power blackouts
Employing DRaaS to prepare for a disaster
True DRaaS draws parallels with an entire infrastructure in fail-safe mode, albeit on virtual servers— including computing, storage, and networking functions. As a company, you may continue running apps —it’s just that now they operate from the cloud or hybrid cloud service provider environment instead of the disaster-affected physical servers.
It implies that recuperation time after a crash can be much quicker or even more immediate. Once the physical servers are restored or substituted, data alongside the processing functionality is moved back to them.
Consumers may experience higher latency when their applications run from the cloud instead of on-site servers; However, since the overall downtime expense can be exorbitantly high, it’s vital that the enterprise get back up and running quickly.
How does disaster recovery work as a service?
DRaaS operates by mirroring and hosting servers in third-party provider facilities instead of the company’s physical location. So, the disaster recovery plan is enforced at third-party vendor installations in a crisis situation that blackouts the customer’s site. Organizations can buy DRaaS plans using a regular subscription or a pay-per-use model that enables them to spend only when disaster hits. As-a-service solutions differ in nature and cost — companies can assess possible DRaaS suppliers based on their own specific requirements and budget.
DRaaS will save money by removing the need to house and manage an organization’s own off-site disaster recovery ecosystem. Businesses should, however, review and recognize service level agreements before taking the plunge. For instance, what happens during recovery times when both the supplier and consumer are affected by the same natural disaster, such as a major hurricane or earthquake?
Disaster Recovery as a Service benefits
Many organizations with lean IT teams simply cannot afford to invest the resources required to study, execute, and thoroughly evaluate disaster recovery plans. DRaaS takes the responsibility of emergency planning off the company and places it in disaster recovery experts’ hands. It can also be much more economical than hosting your own disaster relief facilities in a remote area with IT workers on standby.
