Disaster Recovery in Cloud Computing

Ensure Business Continuity and Seamless Disaster Recovery

Business Continuity and Disaster Recovery

Organizations must be prepared for all forms of disasters, whether they cause hardware failures, cyberattacks, or natural disasters. A company's business continuity in the case of a disaster is heavily reliant on its capacity to replicate systems and data.
Data loss may have a significant financial impact on enterprises and can even harm their brand through a lack of client confidence. As a result, careful preparation and the development of a plan for coping with possible disasters are critical for reducing the negative impact on a firm in the long run.

Disaster Recovery (DR) ensures that activities continue uninterrupted in the case of a disaster. Most big firms devote 2-4 percent of their IT budgets to disaster recovery planning, with others paying up to 25 percent to reduce infrastructure risks.

The Key Considerations for a Disaster Recovery Plan for Cloud Services

A disaster recovery plan considers how to prepare and respond to a disaster, along with the measures necessary to assure system/operation restoration.
According to Gartner's 2017 Security and Risk Survey, 80% of worldwide IT firms have suffered at least one major outage or system failure in the last few years, prompting them to develop a disaster recovery strategy.

Disaster recovery planning comprises the following factors:
  • Programs and data: DR plans must account for data also the programs independently. Programs include the software that powers an organization's activities, whereas data comprises customer accounts and business-related information.
  • Dependencies: Software dependencies must be determined, as specific applications may require the loading of more software before the present software can function.
  • Personnel: It's also crucial to figure out who will be responsible for recovering the systems and data.
  • Compliance: Before continuing operations with recovered data, organizations in specific industries, such as healthcare, may have to guarantee regulatory compliance and security

Types of Cloud Disaster Recovery

There are three types of cloud-based data protection services:

  • Backup as a Service (BaaS)
  • Recovery as a Service (RaaS)
  • Disaster Recovery as a service (DRaaS)

Utilizing BaaS, the cloud service provider (CSP) backs up and fixes contract data.
RaaS is an extension of BaaS where applications restore from the cloud along with data.
DRaaS is much more comprehensive than RaaS and includes cloud-based failover in addition to backup and recovery services. Adopting DRaaS is essential for organizations that require 100% availability of their critical applications.

Advantages of DRaaS

Disaster Recovery as a Service (DRaaS) contains several features never present in traditional backup and disaster recovery approaches. These are some examples:

  • High performance, resiliency, and flexibility
  • Addressing mobility and portability issues in a way that is both effective and efficient
  • Operational resource use is substantially lower.
  • In the case of a disaster, data recovery is quick and painless.
  • Rapid restoration of regular operations.

Disaster Recovery Options

According to the level of security and services needed, DRaaS can be categorized into three types as follows:

  • Self-service DRaaS: This is the basic version of DRaaS. The organizations work with DRaaS providers to purchase only public/private clouds for data storage and manage the data protection process and recovery.
  • Assisted DRaaS: In this case, enterprises construct and administer the DR plan with the possibility of enlisting the help of the DRaaS provider. The supported DRaaS option is suitable for enterprises that want the advantage of the cloud's flexibility. Because the provider is not monitoring the process from start to finish, the Service Level Agreement does not promise a defined recovery time (SLA).
  • Managed DRaaS: In the managed DRaaS model, the DRaaS provider is in charge of data protection and recovery deployment and monitoring. Managed DRaaS entails full SLAs with enterprises eligible for payment for unfulfilled goals. Because of the additional functions, managed DRaaS is often substantially more expensive than assist and self-service DRaaS models.

Benefits of Implementing Cloud-based Disaster Recovery

There are various benefits to hosting a disaster recovery program on the cloud. Some of the direct uses are as follows:

  • Elimination of disk and tape backups: Cloud disaster recovery entails real-time data backup in the cloud that removes a need for daily backups using disks, tapes, flash drives, and other methods.
  • Storage of mission-critical data offsite: If a production center has permanently or temporarily destroyed, data is retrieved, and the production is restored on time, thanks to widely distributed cloud servers that construct redundantly in remote geographical regions.
  • Cost-cutting: A cloud disaster recovery solution is cost-effective since enterprises don't have to duplicate expensive gear and merely pay for the services provided by the cloud service provider.
  • An implementation that is both reliable and simple: In contrast to cloud restoration, which has dependability of at least 99 percent, data restore operations might cause issues when utilizing physical backups such as tape drives, disks, and so on.
  • Faster recovery: Cloud-based DR decreases the time for the Recovery Point Objective (RPO), the particular duration an organization decides to tolerate data loss, and the Recovery Time Objective (RTO), the highest time an organization may allow system outage, from weeks to days and hours.
  • Scalability: The utilization of Cloud DR services may be scaled up or down based on company needs, with payment due only for actual use.
  • Efficiency: Storing data in the cloud reduces capital expenses and increases disaster management efficiency by eliminating the need for big servers and complicated hardware.
