To protect your company against IT system and force majeure disasters, employ disaster recovery as a service (DRaaS), which offers the ability to instantly switch to a replica of your infrastructure created in CROC’s cloud. As a result, your business processes will not stop, even for a single minute, and neither customers, nor employees, will notice any IT failures.
- Any combination of physical, virtual and cloud infrastructures
- Infrastructure backup in any distance
- Guaranteed IT infrastructure recovery time
- Own data centers with TIER III Gold Certification of Operational Sustainability
КCROC’s DRaaS portfolio
Depending on the customer’s tasks and the priority of applications, CROC offers two DRaaS approaches:
- High availability (HA): CROC’s cloud acts as a backup site where a replica of the customer’s infrastructure is created and kept updated and active, with the customer being able to switch to it in only a few seconds in the case of any local infrastructure failures. This is a good option for the recovery of mission-critical services.
- Disaster Recovery (DR): Turning a stopped replica on takes a bit more time — several minutes. This is a good option for the recovery of business-critical services,. while the cost of the service is less than that for active replica use.
Technical aspects of service provision
HA vs. DR
An active infrastructure replica (HA) is created via service clusterization and app-enabled replication.
Disaster recovery using a stopped replica (DR) employs Zerto, Veeam, and Double-Take software.
Zerto solutions perform agentless replication: as replication is at hypervisor level, there is no need to install agents on each VM. While much easier to configure and administrate, this option is only for the VМware vSphere and Microsoft Hyper-V virtual environments. The Zerto solution does not employ VM snapshots and thus can be used for high-loaded VMs. Veeam is ideal if this solution has already been used in the customer’s infrastructure: in this case, the replication system is administered via a familiar backup system console.
The solution performs replication at the operating system level. To that end, a Double-take agent should be installed on each system being protected. While slightly more complicated in terms of administration (compared to agentless), this approach can be applied to any infrastructure configurations, including physical non-virtualized environments.
CROC’s VMware vCloud based cloud segment already includes Zerto Virtual Replication and Veeam Cloud Connect. Combined with the disaster-tolerant architecture of the cloud, which is distributed between two sites, this ensures that virtual machines stay protected, even after complete failure of the main data center.
How to use DRaaS
CROC offers several cloud options for the creation of disaster-tolerant infrastructures:
- Customer operates its own data center and uses CROC’s cloud as a backup site
- Customer deploys a business-critical app in the cloud and backs it up to two cloud platforms
- Customer builds a disaster-tolerant infrastructure based on CROC’s data centers
