To remain competitive today, many organizations feel the pressure – and, therefore, strive – to be down as little as is possible. This need to have services and applications available to customers and employees alike is so great that downtime itself is now measured in counts of single-digit minutes.
Traditionally, recovery is a function of backup – only maintain a daily backup, and there’s no way you can possibly recover to within minutes of a disaster. No, recovery of this caliber needs a different kind of DR strategy – one where data is replicated, rather than backed up; where standby services and applications are lying in wait, rather than require a lengthy data restore to be operational; and where recovery is more about a single simple network failover than about a complex recovery of multiple systems and applications. A recovery like this is what empowers businesses to recover in mere minutes.
Disaster Recovery as a Service (DRaaS) should be thought of as a means of achieving simplicity in your failover and failback during a disaster event. This is accomplished through the right strategy using a mix of your internal IT and the service provider. The beauty of DRaaS is that it is leveraging a provider, as needed, to ensure recovery is simple, effective, and efficient.
DRaaS as Part of Your DR Strategy
In a typical DRaaS scenario, everything needed for a recovery should already in place – onboarding of data and applications is complete, internal and provider teams are synced up on failover processes, servers and services are replicated, and the recovery environment is configured for failover. The only thing left to be done is the failover itself during a disaster event.
So, to make this happen, your DR strategy is more about helping the DRaaS provider define the scope of the recovery, including which systems and applications are to be included and the expected recovery objective timeframes:
- Recovery Time Objective (RTO) – Your DRaaS provider will be asking you how long will you allow the recovery to take? Or, put differently, how much time are you willing to be down?
- Recovery Point Objective (RPO) – Your DRaaS provider will need to understand how much data are you willing to lose (which determines the recovery point in time).
To ensure a successful DR strategy, defining the recovery process – from defining backups to building the recovery environment, to establishing, testing and executing recovery plans – needs to be handled by the DR provider. Once this is defined, you now have an understanding of how DRaaS (and the chosen provider) will help to achieve your recovery goals.
Eliminating the Confusion: DRaaS
DRaaS is about partnering with a provider to define a plan and an environment that facilitates fast recovery of your organization’s most critical workloads. While truly defined by the gaps in your organization’s expertise or execution ability, the use of DRaaS with a trusted provider does instill within the organization the confidence that, should a disaster event occur, operations will continue within minutes.
