The core technology behind Disaster Recovery as a Service (DRaaS) has evolved for decades. More recently, DRaaS has linked to the cloud, and finally hit its stride. Today it can provide unprecedented availability options to companies who don’t have secondary data centers dedicated to business continuity. Before now, only IT teams with additional IT budget, staff and geographic locations could effectively hedge against downtime, and disasters.
But today’s DRaaS means that businesses of all sizes have the peace of mind that comes with knowing a replica of their data and systems is hosted at a remote site that they can fail over to—without bearing any of the infrastructure costs or maintenance responsibilities. All infrastructure and maintenance is the responsibility of the DRaaS provider. And the technology ensures that a replica is not only available, but always current and immediately available. This attractive value proposition led Gartner to predict that global DRaaS revenue will reach $3.4 billion by 20191.
As the DRaaS market heats up, end users are finding that different DRaaS providers offer different service levels. While most offer cloud failover, they differ in the degree of self management
required to configure protection, perform recovery and execute test failovers. There are also different levels of dependency mapping and orchestration available, which can
affect the speed of recovery. The challenge for decision-makers is to make sure any solution can, in fact, deliver on the promises of DRaaS.
