4.1 DRaaS (Disaster Recovery as a Service) Service

 For technical or sales support contact our team of experts.
Disaster Recovery as a Service (DRaaS) allows you to protect your Aruba Private Cloud infrastructure with a quick, professional, simple and safe Disaster Recovery service.
By using the self-service Web Panel via secure connection, users can create Disaster Recovery directives and policies, by choosing the source (primary site) and destination (secondary site) between your VMware on-premise virtual infrastructures and/or the Aruba datacenters enabled for the Private Cloud service. Within just a few minutes it’s possible to create self-consistent replicas between remote sites and activate a perfectly functional Disaster Recovery process.

When defining a Disaster Recovery solution, it’s important to consider two key measurement parameters: the RPO and RTO.
  • the RPO (Recovery Point Objective) represents the maximum misalignment you are willing to tolerate between the production environment (primary site) and replica environment (secondary site). It therefore describes how much data is left unsynchronized in case of disaster.
  • the RTO (Recovery Time Objective) represents the time required in order to restore your  services on the secondary site, following a disaster. It therefore indicates how long it takes to complete the disaster recovery process in order to reactivate your services.
The replication system used by the service is based on Zerto technology (state of the art in  virtualized VMware Disaster Recovery solutions) which optimizes, deduplicates and compresses the data to be protected guaranteeing minimum impact on the required bandwidth, and reducing the obtainable RPO. In particular the system reduces the RTO to periods which can vary from a few seconds to a few minutes, even for international distances.

A low RTO is ensured by easy use, guaranteed by a simple and safe self-service control panel which, with a single button, allows you to automatically start the recovery (Failover) process. Within a few seconds the system is able to switch the production workload to the Disaster Recovery site.

To test the Disaster Recovery process it's possible, at any time and very easily, to run a DR test. The test attempts to restore the system after a disaster, by activating the servers on the secondary site, without interfering with the production servers (primary site), allowing you to check that the replication and Disaster Recovery process are working correctly.

Like with all Aruba services, this also comes with the "Managed" option to let the Aruba qualified technical team fully manage your Disaster Recovery solution.
