Why Hosted Solution?
The concept of cloud has significantly evolved the global computing space making
people, processes and technology to be more converged than ever. The days of worrying
over whether the ISP has gone down or generator is faulty are fading away; thanks
to the commitment of collocation organization whose resolve is to remove the burden
of concerns away from organization IT team.
Business continuity, uptime and reliability, disaster management and cost are probably
the salient reasons why organization would want to would consider positioning server
infrastructure in a managed cloud environment.
Hosting as a Disaster Recovery and Business Continuity strategy
There is no formula to predicting when disaster will occur. There are no fool-proof ways to
preventing them. Human is yet to invent the technology to subside or stop the raging
wing, the hurricane, the tsunami, earth quake, thunder and lighting. Even the disasters
that have logical inferences like server crashing, data centre inferno, war, unrest
and vandalism are still very much out of human’s control.
Reliance Infosystems hosting solution presents the confidence of data survivability
in any instant of disaster. When your server crashes, we are giving you an automated
solution that brings up a new server with your most recent data within minutes and
with no effort. When your data centre gets gutted by fire, we are giving you the
peace of mind that your fully-functional and up-to-the-minute secondary data centre
is ready to continue to serve your users with all the servers already in place.
These “miracles” are only achievable through virtualization technology and our unique
cloud computing solution.
Depending on your requirement and environment, we recommend one of the following
Remote Branch Hot Site
This model allows companies with hot site-capable facility to be used for DR and
BSC site thereby allowing users to either manually or automatically failover to
hotsite location when the production site has issues. This solution is wholly-owned
by the customer.
Private Cloud Hot site
The DR and BSC solution is totally outsourced to third party facility. The third
party is responsible for hardware, power, data and cooling. The replication technology
can be owned by the customer, reseller of platform provider. Reliance Infosystems
partners with Rackspace (UK) to provide this solution.
Public Cloud Hot Site
This model involves the use of Microsoft Azure services to provide site and server
replications. The platform and technology is wholly-owned by Microsoft while Reliance
Infosystems is involved in the implementation and maintenance of Windows Azure data
replication from On-premise locations.
Hosting and Virtualization Technology
By virtue of our competency status on Hosting, Reliance Infosystems leverages Windows
2012 R2 HyperV role to implement hosting solution for our customers.
Windows Server 2012 Hyper-V Role introduces a new capability, Hyper-V Replica, as
a built-in replication mechanism at a virtual machine (VM) level. Hyper-V Replica
can asynchronously replicate a selected VM running at a primary site to a designated
replica site across LAN/WAN. The following schematic presents this concept.
Here both a primary site and a replica site are Windows Server 2012 Hyper-V hosts
where a primary site runs production or the so-called primary VMs, while a replica
site is standing by with replicated VMs off and to be brought online, should the
primary site experiences a planned or unplanned VM outage. Hyper-V Replica requires
neither shared storage, nor a specific storage hardware. Once an initial copy is
replicated to a replica site and replication is ongoing, Hyper-V Replica will replicate
only the changes of a configured primary VM, i.e. the deltas, asynchronously.
