DRaaS

• DRaaS is the abbreviation for Disaster Recovery
  as a Service. It uses cloud computing and enables
  a company to back up its IT infrastructure and
  data in the cloud computing environment of a
  third party. In it, all the disaster recovery
  orchestration is provided through a SaaS
  (Software as a Service) solution in order to
  re-establish functionality of IT infrastructure
  and regain access to it, post a disaster (natural
  calamity, cyber-attack, equipment failure etc.).
• This service model ensures that a company neither
  needs to own all the resources nor carry out the
  management of disaster recovery, which is taken
  care of, in its entirety or partially, by the
  service provider. Disaster Recovery as a Service
  is beneficial for such businesses that do not
  have the required expertise to configure, test,
  and have in place an effective plan for disaster
  recovery.

Factors to Consider while Opting for DRaaS

• The main factors that need to be taken into
  account while selecting DRaaS are as follows-
• Hidden fees- Since the costs for DRaaS vary
  considerably find out about hidden fees that can
  add up substantially.
• Availability of SLA with regard to performance-
  Ensure the availability of an SLA (Service Level
  Agreement) contract between you and the service
  provider. This helps to predefine performance.
• Availability of payment based on use- Opt for a
  service where you pay for only the resources that
  you use.
• Availability of options- Select a service
  provider that is able to provide different DRaaS
  for different types of applications.

Factors to Consider while Opting for DRaaS,
Continued

• Options for Cloud seeding- When Cloud seeding is
  present, physical media, such as hard disks,
  servers etc., can be used to pre-load data to the
  cloud for restoring a local database that has
  encountered some failure.
• Provides automated test recovery- Opt for a
  service that ensures automated testing,
  especially post making any change to the
  infrastructure.
• DRaaS that protects Cloud applications- An ideal
  DRaaS is well-equipped to serve its purpose for
  Cloud applications.

8
Drawbacks of DRaaS

• The major drawbacks of DRaaS are-
• Availability of limited bandwidth when a
  large-scale disaster happens
• Less control due to outsourcing of services
• Risk related to overpaying
• Security concerns

Three Main DRaaS Models

• Businesses might utilize the services of DRaaS
  providers entirely or partly for disaster
  recovery. The three main models for Disaster
  Recovery as a Service are mentioned below, in no
  particular order.
• Managed DRaaS- A third party service provider is
  responsible for the total disaster recovery in a
  managed DRaaS.
• Self-service DRaaS- In this model for DRaaS, it
  is the users responsibility to plan, manage and
  test disaster recovery. It is the least expensive
  among the three models.
• Assisted DRaaS- In Assisted DRaaS, the service
  provider ensures optimization of the procedures
  for disaster recovery and it becomes the users
  responsibility to implement partially or entirely
  the disaster recovery plan.
