FEATURE: DISASTER RECOVERY
market is expected to grow by a CAGR
of 52.9% from $1.42bn in 2015 to
$11.92bn in 2020.
There are four key arguments in
favour of DRaaS:
Increased flexibility
If an organisation chooses to
have a physical secondary site for
their DR services, then it is essential
that this site be a carbon copy of the
primary production site. This can be
an extremely daunting task in of itself
but even if done properly, there is
the burden of having to continuously
monitor the systems to ensure that they
are synchronised. The advantage of
DRaaS is that this synchronisation can
be abstracted. Another advantage of
DRaaS is that depending on the disaster
mode, the organisation can select from
a variety of options for how to handle
the different business systems.

Since most of the processes are
automated, opting for a DRaaS
solution also frees up IT resources
and gives them the flexibility to focus
on business critical applications, that
can yield tangible business benefits,
rather than on support functions.
2
Reduced costs
Organisations that choose to
deploy physical secondary sites to
support DR services have to make a
significant CapEX outlay associated
with the physical infrastructure,
hardware and software licenses
and regular maintenance. DRaaS
on the other hand works on a
subscription/’pay-as-you-go’ model.
Organisations only have to pay for
the services they uses which works
out to be extremely cost effective,
particularly for smaller organisations
that are cash strapped or for
organisations whose DR requirements
might frequently scale up or down.

More robust testing
Regularly testing the DR system
is a key part of any BC/DR strategy.
Unfortunately given the synchronisation
issues with traditional DR systems,
testing is both extremely expensive
and time consuming which is why
