As the 2015 Atlantic hurricane season continues to batter the northern hemisphere causing dramatic loss of life and damages, it heightens awareness around the importance of disaster recovery. But where to start?
With all the well deserved enthusiasm around cloud, Disaster Recovery as a Service (DRaaS) is an option worthy of consideration. Simply put, DRaaS is a cloud computing and backup service model that uses cloud resources to protect applications and data from disruption caused by disaster and gives organizations a total system backup in the case of system failure of any kind. The design points should address these seven criteria:
- Do your plans include the possibility of redirecting all customer traffic to the cloud?
- If you plan to restore from the cloud to on-premises infrastructure, how long will that restore realistically take?
- Does the cloud provider meet all regulatory requirements?
- Is data securely transferred and stored in the cloud?
- How are users authenticated?
- What are your RTOs?
- Which applications within your organization can be segregated based on level of importance?
Armed with this knowledge, IT leaders can review the DRaaS options and develop a solution that best meets the organization’s unique needs and budget requirements. The three main DRaaS options are:
- Fully managed cloud DR, where both primary production and disaster recovery instances are placed in the cloud and handled by a managed service provider. They can be 100% managed backup and DR, or something less complex.
- Back up to and restore from the cloud is an alternative in which applications and data remain on-premises, with data being backed up to the cloud and restored on-premises when a disaster occurs.
- Back up to and restore to the cloud, where data isn’t restored to on-premises infrastructure. Instead, it is restored to virtual machines in the cloud, for optimal RTO and RPO. With that said, it can be more complex and must be designed and implemented well.
A deployment of cloud services without clearly defined requirements can result in sub-optimal cloud resources and increased risk. At Sirius, we provide cloud solutions across all deployment models, as well as full consulting services. Our services start with a complimentary Cloud Briefing, in which our cloud engineers and architects work with your team to understand your pain points, cost challenges and future requirements. Based on their findings, they’ll recommend a strategy that includes the optimal combination of on-premise systems (private cloud), third-party services (public cloud), or a mixture of the two (hybrid cloud).
