RE Cloud Backup as a Service (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.

1. RE Cloud BaaS
Disaster Recovery Supporting Infrastructure
RE Cloud Backup as a Service (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.
We provide our 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.

2. RE Cloud BaaS – Disaster Recovery Supporting Infrastructure
With the release of disaster recovery in RE Cloud for our BaaS clients, there is one common
question that customers keep asking me, and that is ‘Where do I run required supporting
infrastructure like Active Directory, DNS, and other services I need?’
You may, or may not be aware about how closely our main offerings RE Cloud IaaS and RE
Cloud BaaS work together. RE Cloud provides our 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 you 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
we advise against it. So what should you do?
It is a 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 your RTO as your VCD will be already configured and connected to your corporate HQ
or other sites. Your DR Run Book will therefore be dramatically thinner. RE Cloud offers a few
options for solving the need for these running virtual machines.

3. VPN between your 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.

4. Private Leased Line
Some customers due to bandwidth or compliancy needs may require a leased line or MPLS

5. Cloud to Cloud VPN

RE Cloud vDC can communicate with any other private or third party cloud provider devices
that support IPSec.

6. Other Considerations

As with almost anything in IT, there are some considerations:
• For VPN, the endpoint network cannot be the same
• You should define your new RE Cloud network in Active Directory as a new ‘Site’ and
assign the correct domain controller
• Make sure that your VPN endpoints have the correct firewall rules to pass the traffic
between sites
In the above diagrams I have tried to show some level of detail of the networking so you can
get the basic idea. A correct design will most likely differ from case to case, but that is why
you’ve chosen RE as your cloud provider. Our transformation consultants will engage to help
you with architecting the correct design.
