Disaster Recovery as a Service (DRaaS) for Optimal Failover
Solid disaster recovery is imperative. However, not everyone has the means to employ a traditional disaster-recovery infrastructure, which has given rise to Disaster Recovery as a Service (DRaaS). DRaaS is the replication and hosting of physical or virtual services by a third-party to provide failover in the event of a man-made or natural catastrophe.
Today, DraaS is exploding in the marketplace as a strategic offering. Cloud infrastructure providers are leveraging it to drive demand and create a stepping stone into their public cloud solution sets, and this is actually a very good idea. It creates a win-win for the consumer, and it offers a way for the cloud-based infrastructure market to generate momentum with small-to-medium businesses (SMBs) and enterprise customers. Many customers today want to live in the cloud or experiment with hybrid clouds as a way to augment to their infrastructure, but it’s difficult for them to determine a starting point.
To implement a successful DRaaS architecture, you need three primary components operating as a whole:
- A hosting provider to provide the infrastructure and virtualization platform.
- Software to enables the replication and orchestration of a disaster recovery failover scenario
- A cloud consultant and services team to plan, implement and perhaps manage the solution to maturity and beyond.
Each hosting provider approaches DRaaS differently, with specific goals and offerings that are strategic to their own product suite, which makes the provider landscape very confusing. Understanding what’s offered in a providers’ package is sometimes difficult to quantify and quote properly.
The industry currently only provides estimates—there are just too many variables in the leasing of compute. To make an evaluation, we need to look for some indicator features that swing the price, such as the size of the provider and the virtualization technology architecture. (Are they VMware/HyperV?) As things evolve, there will likely be some consolidation, which is both a risk and a concern. Standards are now emerging that will assist with this, but having experience and relationships with multiple infrastructure providers is always wise. And leveraging experienced cloud architect consultants like those here at ASG can help bring a DRaaS solution together.
