DRJ | The premiere resource for business continuity and disaster recovery

Efficient Disaster Recovery as a Service

The future has been integrated to give utmost importance to business continuity. The various models of data protection and disaster recovery are starting to be prioritized as data generation is growing daily. In order to meet the data protection disaster recovery requirements now and in the future, storage is needed that is automated. Such storage will facilitate disaster recovery and data protection processes and testing, offload IT staff and enable the firms to better support DevOps needs and private cloud. An example of such storage is the efficient cloud storage provided by Microsoft Azure storage.

Technology and DRaaS: Efficiency and Reliability

Cloud service providers have to provide cost-efficient backup which is lined with maximum resource utilization for greatest performance. To offer disaster recovery as a service (DRaaS), however, the service provider may have to over provision storage to satisfy customer needs in case of a failure. Moreover, different demands of customers require a cloud storage service provider to provision different storage systems for each customer.

Modern storage systems with per VM quality of service (QoS) can solve this problem. Per-VM QoS allows for the establishment of tiers of service on a single array; setting maximum or minimum QoS thresholds for groups or even individual VMs. Service providers can hence consolidate data from multiple customers onto a single array and guarantee that each customer will receive the QoS they are contracted for. DRaaS is a fast-growing and increasingly important use case for cloud service providers, but the storage needed should provide customers with policy management and SLAs necessary to manage these advanced services.

DRaaS offerings allow companies to eliminate the complexity and expense of maintaining a datacenter for disaster recovery and shift CapEx to OpEx.

Importance of Storage

Storage is a vital part of data protection and disaster recovery success, a service provider’s storage should integrate with all other elements in the storage environment. Other elements include other data, hardware, hypervisors, protection software, etc. As a customer, storage should be chosen which has wide integration from a company that understands data protection and can support your entire business.

The storage that is chosen should integrate with other elements of disaster recovery and data protection and datacenter environments. The storage solution needs to integrate with the hypervisors that are being run.

  • Microsoft Hyper-V, including ODX support.
  • VMware vSphere, including VASA and VAAI support.

Disaster Recovery and Data Protection Software

  • As a customer, look for vendors that work with data protection/ disaster recovery leaders such as Veeam software or the Veeam cloud connect to Microsoft Azure.
  • In the best case, a customer’s chosen storage vendor should have a good relationship with other vendors whose software are intended to be used.
  • If you’re a VMware Site Recovery Manager (SRM) user, check for integration.

Some storage providers offer plug-ins for direct access to disaster recovery/data protection features and greater levels of integration with the products above.
