This is the fifth installment in a blog series focused on the needs of Service Providers. You can find links to all blogs in this series at the end of this article.

 

Because of the expense of maintaining a secondary location for disaster recovery and remote backup, companies of all sizes are looking to take advantage of the cloud for these functions. In particular, small and medium-sized businesses (SMBs), who may not have a second datacenter or be able to afford to duplicate infrastructure, are interested in these services.  With the launch of the Nutanix Xpress platform, this need is growing rapidly.

 

DRaaS and DPaaS providers fill this need. The challenge is to create an infrastructure that can efficiently ingest large amounts of customer data while also providing the necessary compute capacity to bring up customer applications during a system failover, all with low TCO to give you better margins.

 

Flexible Infrastructure

A Nutanix Enterprise Cloud supports flexible platform options to scale compute and storage and the ability to repurpose infrastructure quickly to address failover scenarios. A big advantage of the Nutanix approach is that you can support different types of services using the same infrastructure (IaaS, DaaS, managed services, DR, backup, and so on) so you don’t have to dedicate silos of resources for each service, and you have a lot of flexibility to change the resource mix as you grow.

 

For example, a mixed cluster consisting of storage-heavy nodes for data ingest and a smaller set of compute-heavy nodes to support failover scenarios is ideal for DR and backup. As you grow out your services, you can easily rebalance resources incrementally: more capacity to support a higher proportion of backup customers, more compute to support a higher proportion of DR customers, and so on. Excess compute capacity can be allocated for another service entirely such as IaaS.

 

Building Blocks for Data Protection and DR

Nutanix provides a set of features that are foundational for backup and DR. All services are VM-centric and optimized for virtual environments. All services but synchronous replication are based on Nutanix’ space-efficient snapshot capability.

 

Other snapshot implementations rely on time-consuming data copies or use copy-on-write (COW) algorithms that affect write performance and limit the number of snapshots that can be kept. The Nutanix approach mitigates these limitations. Because Nutanix snapshots have access to all the storage capacity available on a cluster, you can store more snapshots for longer periods without worrying about the complexities of reserving space or maxing out individual LUNs or volumes.

 

For backup, Nutanix provides local and remote capabilities:

  • Local backup uses snapshots protected by the resiliency of the Nutanix architecture.
  • Remote backup replicates periodic snapshots to a second datacenter.

Both services benefit from deduplication, compression, and Nutanix EC-X. With EC-X, erasure coding across nodes provides superior resilience while reducing capacity requirements. This combination of technologies saves significant capacity, allowing you to increase margins—or undercut competitors on price.

 

For disaster recovery, Nutanix provides both asynchronous and synchronous replication.

 

  • Asynchronous replication allows a single data stream to support both backup and DR requirements, saving network bandwidth and secondary storage.
  • Synchronous replication is provided by Nutanix Metro Availability. Data is written synchronously to both sites, so it is available to applications in the event a site fails or needs maintenance. You can non-disruptively migrate VMs between sites for planned maintenance events or other needs.

DR/DPaaS for Existing Nutanix Customers

Nutanix has over 2,500 customers with a rapidly growing installed base across a variety of industries including healthcare, financial services, government, education, media and entertainment and many others.

 

Service providers who deploy Nutanix infrastructure can offer backup and DR services using native Nutanix capabilities as a value add to Nutanix customers. Both asynchronous and synchronous services can be architected to give customers autonomy over their DR environments or to provide managed DR, where your team manages customer services that failover.

With the Nutanix App Mobility Fabric (AMF), customers can run their choice of hypervisor on-premises and transparently failover to a different hypervisor running at your site.  For example, a customer might run ESXi on-premises, but you might run AHV to save on hypervisor licensing costs and simplify management.

 

DR/DP as an Adjunct to IaaS and Managed Services

If you are an Infrastructure as a Service or Managed Service Provider who uses Nutanix infrastructure, you can use Nutanix-native DR and backup to create and offer premium data protection services for your customers without making big investments in additional hardware and software.

 

Even synchronous replication can be offered as a premium service with minimal constraints. The only network requirement is a roundtrip latency between sites of 5 milliseconds or less. These services benefit immediately from Nutanix data reduction, saving you network bandwidth and capacity.

 

DR/DPaaS for Non-Nutanix or Heterogeneous Customer Environments

For customers with on-premises infrastructure other than Nutanix, you can offer DR and backup services utilizing well-known data protection software from industry leaders such as CommVault, Veeam, and Zerto. Nutanix is partnering with industry-leading data protection companies to support a wide range of options.

 

A Nutanix enterprise cloud solution gives service providers a lot of flexibility to architect DR, backup, and other services without creating silos of specialized infrastructure and without having to license a lot of additional software from multiple vendors.
