RE Cloud Backup as a Service (BaaS) is pleased to announce the launch of disaster recovery supporting infrastructure. RE Cloud BaaS is a cost-effective managed cloud backup and restore solution for physical and virtual environments on customer sites. It provides an easy way to restore critical data in the event of hard drive crashes, power surges, dropped or stolen laptops, accidental deletes and even full-blown disasters.
RE Cloud have BaaS clients with the facility for an on-demand virtual data centre in RE Cloud at no extra cost. Virtual machines are stored on the cloud via RE Cloud BaaS. In the event of a disaster customers can opt to restore service in RE Cloud simply and cheaply via the portal or through a managed recovery provided by the RE Cloud Support Team.
RE Cloud BaaS – Disaster Recovery Supporting Infrastructure:
With the launch of disaster recovery in RE Cloud for their BaaS clients, there is one common question that customers keep asking, and that is ‘Where do they run required supporting infrastructure like Active Directory, DNS, and other services they need?’
Customers may, or may not be aware about how closely RE Cloud IaaS and RE Cloud BaaS work together. RE Cloud now provides its Backup as a Service clients with an on-demand virtual data centre (VDC) in the event of a disaster. Virtual Machines and physical servers with image backup schedule can be restored to a pre-configured VDC in RE Cloud simply and cheaply. The replicated workloads use only storage resources until customers fail them over. There is no compute and memory utilisation until these machines are powered on. Supported infrastructure can of course be included in those recovery groups, however RE Cloud advise against it. So what should you do?
It is general industry practice to run the supporting infrastructure, like for example a Domain Controller, hot and always on in the DR site and there are many reasons why. The DR site will most likely have a different IP address range and therefore it can be treated as simply another ‘site’ in Active Directory with its services running there, waiting for failed over machines to use them. Secondly, running a hot workload in DR can dramatically cut down RTO as clients VCD will be already configured and connected to clients corporate HQ or other sites. The clients DR Run Book will therefore be dramatically thinner. RE Cloud offers a few options for solving the need for these running virtual machines.
VPN between clients physical and RE Cloud resources:
In cases where a company hosts their workloads in their own location or data centre and because of some reasons leased line is not required, an IPSec VPN tunnel can be created. vShield Edge Gateway follows strict IPSec industry standards, therefore it is possible to create a secure communication tunnel with any other 3rd party device.
Private leased line:
Some customers due to bandwidth or compliancy needs may require a leased line or MPLS. This diagram illustrates private leased line.
Cloud to Cloud VPN:
RE Cloud vDC can communicate with any other private or third party cloud provider devices that support IPSec.
As with almost anything in IT, there are some considerations:
- For VPN, the endpoint network cannot be the same
- Define new RE Cloud network in Active Directory as a new ‘Site’ and assign the correct domain controller
- Make sure that VPN endpoints have the correct firewall rules to pass the traffic between sites
- In the above diagrams RE Cloud have tried to show some level of detail of the networking in order to get a basic idea. A correct design will most likely differ from case to case, but that is why clients have chosen RE Cloud as their provider. RE Cloud transformation consultants will engage to help clients with architecting the correct design.
