Disaster recovery
as a service(DRaaS) is a cloud computing service model that allows an organization
to back up its data and IT infrastructure in a third party cloud computing
environment and provide all the DR orchestration, all through a SaaS solution,
to regain access and functionality to IT infrastructure after a disaster. The
as-a-service model means that the organization itself doesn’t have to own all
the resources or handle all the management for disaster recovery, instead
relying on the service provider.
Managed Disaster Recovery service (DRAAS) cloud computing service prototype that allows
organizations to recalculate data and IT infrastructure in a third-party cloud
computing environment and provide access to all DR orchestrations through SAS
solutions and functionality. . The model of service for post-disaster IT
infrastructure means that the organization does not have all the resources or
need to manage all the administration for disaster recovery, but depends on the
service provider.
Disaster recovery
planning is important for the continuity of business. In recent years, many
disasters that have damaged the IT business have occurred repeatedly:
·
Natural disasters such as hurricanes,
floods, wildfires and earthquakes
·
Equipment failures and power outages
·
Cyberattacks
Using
DRaaS to prepare for a disaster
True
DRAAS mirrors the entire infrastructure in file-saving mode on virtual servers,
including computing, storage, and networking capabilities. An organization can
run applications - run them in place of a service provider's cloud or hybrid
cloud environment, rather than physical servers causing disasters. This means
that the post-disaster recovery time can be very fast or fast. Once the
physical servers are found or replaced, processing and data are returned to
them. Users may experience significant delays in running their applications
from the cloud rather than on the site's servers, but the total cost of useless
business is very high, so getting a business up and running is essential.
How does disaster recovery as a service work?
DRaaS works by mirroring
and hosting servers that have workloads in the organization's physical space
against the duties of third party service providers. If a customer is separated
from the site, a disaster recovery plan is implemented at third party vendors.
Companies can purchase DRAAS plans through a traditional membership model or
per-use model, which allows payment only in the event of a disaster. As service
solutions vary in scope and cost, companies should evaluate potential DRAAS
providers according to their specific needs and budgets.
DRaaS
saves companies money by eliminating the need to create and maintain its own
on-site disaster recovery environment. However, companies must evaluate and
understand service level agreements. For example, what is the time of recovery
if both provider and customer are exposed to the same natural disaster, such as
a large hurricane or earthquake? Different DRAAS providers have different
priority-based policies that help clients in the event of major regional
disasters or allow customers to retry themselves.
Disaster recovery as a service advantages
Most companies with thin IT teams do not undergo research,
implementation and comprehensive testing on disaster relief plans. DRaaS has
taken the burden of government disaster planning into the hands of disaster
relief professionals. When disaster strikes, it is less likely to host your own
disaster relief infrastructure. When disaster strikes, this value is not used
for second-hand infrastructure or employees. Most DRAAS providers charge only
when the service is needed. For most companies, DRaaS is a convenient way to
solve difficult problems.
