Disaster Recovery as a Service (DRaaS) in its entirety offers the full suite of components of disaster recovery by a third-party vendor. It consists of a replication product (continuous data protection), an offsite backup product (point-in-time recovery), a disaster recovery plan and vaulting that plan so you can access it in an emergency. A DRaaS provider should also work with you to test your infrastructure, workloads, and all associated components of your applications, including the applications themselves.
Building your own infrastructure can take a vast amount of time and resources and many businesses may not have access to those types of resources. Investing in a DRaaS provider can reduce the costs associated with this type of undertaking. The technology and infrastructure a provider has can offer peace of mind when it comes to backing up your business.
However, as with any outsourced IT project, there is a certain level of trust you have to place in your provider. With DRaaS, your provider must be able to implement the disaster recovery plan and meet the specified recovery point and time objectives without incident. That can be a sizable undertaking, so be sure to thoroughly vet your vendors.
DRaaS is just that—a service. Providers across the board can offer the same or similar technologies, but it’s the people who provide the service that will make the biggest difference when comparing companies. Do they claim to be compliant? Confirm that by checking their reports to make sure they’re practicing what they preach. If you have specific recovery point and time objectives, your DRaaS provider should work with you to achieve them, outlined in a service level agreement.
If you are looking to save money but already have a disaster recovery site in place, you can use a concept called reverse DRaaS. Reverse DRaas allows the customer to host their production environment with a cloud service provider, and in the event of a disaster, fail over to their own infrastructure. This particular service can be useful because it allows clients to use the latest technology for their main site, and then their own site for disaster recovery.
In the end, DRaaS is a good idea for businesses of all sizes looking to put at least part of their infrastructure in the cloud, and it can help give you and your organization a sense of relief when you have to face the unexpected. When researching DRaaS providers, don’t forget to do your due diligence by making sure they are compliant with whatever controls you need, whether that’s SSAE 16, SSAE 16 or PCI. Finally, while the DR portion is key, don’t forget that the “S” stands for service – your provider is there to work with you to help your business whenever you need them! This is what will set each company apart from the other.
