Secure DR as a Service (Server Replication)

Exponential-e DR as a Service (Server Replication) is a fully managed DRaaS service providing geo-replication of protected virtual server workloads running on VMware, Hyper-V, and public cloud environments. RPOs of as little as five minutes can be achieved and RTOs from just 30 minutes.

Features

  • Multi-Hypervisor DRaaS: VMware, HyperV, and Public Cloud
  • Predictable billing models
  • Low RTPOs: Near Continuous Replication
  • Application Groups provide Consistency for Multi-Tier Applications
  • Storage and Application Agnostic
  • Defined Failback Process
  • Isolated Testing facility provides no-impact failover testing

Benefits

  • UK Sovereign: Data is retained in the UK
  • Eliminates the need for a private DR server estate
  • Improved Business Continuity and Disaster Recovery
  • Can be used to effect server migration between platforms

Support levels The DRaaS service is subject to an invocation start time target of 30 minutes. RPO and RTO (combined, RTPO) will depend upon a number of Customer-specific factors. For VMware environments replicating to our IaaS platform, typically RPO will be less than five minutes.

Customer responsibilities include:
- Decision to invoke failover of services.
- Activating software in a failover scenario.
- Requesting the use of test days.
- Ensuring compatibility of all licenses with the target platform.

Our responsibilities include:
- Ongoing management of the Service.
- Invocation of replicated servers.
- Verifying network access to the replication server(s).
Support available to third parties Yes

Onboarding and offboarding

Onboarding and offboarding
Getting started For environments replicating to the Exponential-e IaaS platform, customers are able to seed virtual machine images in order to reduce network bandwidth requirements during the set-up phase.

On-net customers replicating between private or IaaS environments can also benefit from seamless workload transition, without the need to change protected server IP addresses during the recovery process, made possible by our investment in Software Defined Networking (SDN). These techniques can also eliminate risk from permanent workload migration between platforms.
Service documentation Yes
Documentation formats PDF
End-of-contract data extraction If customised data transportation, data extraction or full virtual machine export services are required, for example in the example of a post-invocation off-boarding scenario, these services shall be charged at the prevailing time and materials day rates.

In order to action these customised services, an off-boarding service request must be raised via the Exponential-e Service Desk. Due to those services have not been not included within Exponential-e’s G-Cloud catalogue entry, and thus do not fall within the Framework Agreement and Call Off Agreement, Exponential-e’s standard terms and conditions for professional services would apply.
End-of-contract process At the end of the term and/or if the contract is terminated, the Service Migration provisions will apply.

Energy-efficient datacentres Yes
Description of energy efficient datacentres Critical to our core operation is our national network infrastructure and Data Centres, which house our server and switching equipment, as well as our cloud Infrastructure. Exponential-e recognises that energy efficient practices, and reducing our carbon footprint, are paramount in achieving our corporate sustainability goals.
• All our Data Centres are ISO14001 accredited organisations with robust environmental management systems
• Procuring consumed energy from sustainable energy sources wherever possible
• Ensuring the use of hot/cold aisle cooling design in our Data Centres, which reduces energy consumption as the cooling is more efficient and helps our customers to reduce their carbon footprint
• Use the latest virtualisation (VDC) technologies to ensure the most efficient utilisation of hardware resulting in the overall optimization of our client’s infrastructure. Our VDC delivers dedicated processing instead of having multiple, underutilised physical servers, which helps minimise our environmental impact
