In today’s dynamic business landscape, organizations must be prepared to mitigate the potential impact of disasters and swiftly recover their IT infrastructure. This is where Disaster Recovery as a Service (DRaaS) comes to the rescue. With an emphasis on cost-effectiveness and flexibility, DRaaS offers organizations a lifeline in the face of natural disasters, equipment failures, power outages, and cyberattacks. Many may wonder what is disaster recovery in cloud computing?
Cloud computing empowers organizations by offering various cloud service models, including IaaS, SaaS, PaaS, DRaaS, BaaS, etc. Discover the power of DRaaS in ensuring business continuity and peace of mind when unforeseen circumstances strike. In this blog post, we delve into the concept of DRaaS, its advantages, and how it differs from Backup as a Service (BaaS). Discover how DRaaS empowers businesses to back up their critical data and IT infrastructure in a secure cloud environment while leveraging expert disaster recovery orchestration.
What is Disaster Recovery as a Service (DRaaS)?
Disaster Recovery as a Service (DRaaS) is a cloud computing service model that enables organizations to back up their data and IT infrastructure in a third-party cloud computing environment. It provides comprehensive disaster recovery orchestration through a Software as a Service (SaaS) solution, allowing organizations to regain access and functionality to their IT infrastructure following a disaster. By adopting the as-a-service model, organizations can rely on service providers to handle the resources and management required for effective disaster recovery.
In recent years, various disasters such as natural calamities (e.g., hurricanes, floods, wildfires, and earthquakes), equipment failures, power outages, and cyberattacks have posed significant risks to IT organizations. As a result, disaster recovery planning has become crucial for ensuring business continuity.
How Does DRaaS Work?
Instead of relying on an organization’s physical location and resources, DRaaS replicates and hosts servers in the facilities of a third-party vendor. In the event of a disaster that incapacitates the customer’s site, the disaster recovery plan is executed at the vendor’s facilities. Organizations can opt for traditional subscription-based DRaaS plans or pay-per-use models, allowing them to pay only when a disaster occurs. As-a-service solutions come in various sizes and price ranges, so businesses should assess possible DRaaS providers according to their individual requirements and spending capacity.
By removing the requirement for businesses to set up and operate their own off-site disaster recovery infrastructure, DRaaS delivers cost benefits and flexibility.
However, it’s essential for organizations to assess and understand service-level agreements. For instance, they should consider the recovery times if both the provider and customer are affected by the same natural disaster. DRaaS providers may have different policies for prioritizing assistance in large regional disasters or allowing customers to perform their own disaster recovery testing.
Benefits of DRaaS
There are several advantages to adopting DRaaS. Some important advantages of DRaaS are listed here:
- Efficient DR planning: Many businesses with limited IT resources find it challenging to dedicate time to research, implement, and thoroughly test disaster recovery plans. DRaaS helps them with efficient DR planning, testing, and execution.
- Offloading the DR burden to specialists: Organizations are relieved of disaster recovery responsibility by offloading it to disaster recovery specialists, thanks to DRaaS. DR specialists are professionals who can handle DR scenarios in a better way.
- Cost-effective & Maintenance-free: DRaaS can be more cost-effective compared to maintaining a separate disaster recovery infrastructure with an on-site IT staff, which may go unused if a disaster doesn’t occur.
- Pay-as-you-go: Most DRaaS providers charge only when their services are required, making it an attractive solution for organizations seeking a remedy to this persistent issue.
DRaaS Strategies
Various DRaaS options exist that cater to different business needs. You must consider all DRaaS options to choose the DRaaS strategy that aligns best with your business requirements. To determine whether DRaaS is the right choice, you can opt to delegate either all or part of your disaster recovery planning to a DRaaS provider. There are three primary DRaaS models available:
1. Managed DRaaS: This model entails transferring full responsibility for disaster recovery to a third-party provider. You must maintain close communication with your DRaaS provider to ensure the plan remains up to date regarding infrastructure, applications, and service changes. Managed DRaaS is a suitable option for organizations lacking the expertise or time to manage their own disaster recovery.
2. Assisted DRaaS: Assisted DRaaS allows you to retain responsibility for certain aspects of their disaster recovery plan. This model is beneficial for organizations with unique or customized applications that might be challenging for a third-party provider to manage. While you implement all or part of the plan, the service provider provides knowledge and direction for disaster recovery procedures.
3. Self-Service DRaaS: Self-Service DRaaS is the most economical option, where you, as a customer, take charge of planning, testing, and managing disaster recovery. You host your infrastructure backup on virtual machines in a remote location. Adequate planning and testing are crucial to ensure instant failover to the virtual servers in the event of a disaster. It is suitable for businesses with seasoned internal disaster recovery professionals who are skilled enough to handle tough conditions by themselves with proper planning and execution.
How is DRaaS different from BaaS?
People often get confused in understanding the difference between Backup as a service (BaaS) and Disaster Recovery as a Service (DRaaS). It’s important to distinguish DRaaS from BaaS. With DRaaS, the service provider moves the computing resources of an organization to its cloud infrastructure when a disaster strikes. This allows the business to continue operating even if the original IT infrastructure is completely destroyed or compromised.
In contrast, BaaS only duplicates the data, not the ability to process it, through a third-party provider. BaaS is generally less expensive than DRaaS since it focuses solely on data protection rather than infrastructure. While BaaS can be suitable for companies needing data archiving or record-keeping for legal purposes, most organizations using BaaS will combine it with another disaster recovery tool to ensure business continuity.
Wrapping Up
Every business must take into account the importance of disaster planning and securing essential resources. Regardless of the strategy used, maintaining company continuity requires a clearly defined disaster recovery plan. Organizations are increasingly using DRaaS as a practical response to these issues. The demand of DRaaS is set to increase over time due to its flexibility, reliability, and cost-effectiveness.
