Guide To Disaster Recovery As A Service
DRaaS or disaster recovery as a service refers to a cloud computing service model that lets a company backup IT infrastructure and essential data in a cloud computing environment that is regulated by a third-party group. DRaaS allows an organization to get back its functionality and access to IT infrastructure following an unfortunate disaster. A service model simply means that the company itself does not need to own all of the resources or deal with all of the management needed for disaster recovery.
Instead, they can simply rely on a managed IT service provider. Disaster recovery planning is crucial to business continuity. A lot of disasters that have the possibility to cause damage to an IT organization have become more prevalent over the past few years. These include:
- Power outages
- Equipment failures
- Natural disasters (earthquakes, wildfires, floods, and hurricanes)
DRaaS For Disaster Preparation
A genuine DRaaS replicates an infrastructure that is in the fail-safe model on a virtual server, which includes networking, storage, and computing functions. A company could continue to run an application – it simply runs them from the cloud or the hybrid cloud environment of the IT service provider rather than from physical servers that can be affected by disasters. This means that the recovery time after an unfortunate event will be faster and in some cases, instantaneous. When the physical servers are replaced or recovered, the data and the processing will be migrated back onto them. Clients may experience much higher latency if their applications are running right from the cloud rather than from an on-site server. However, it is better than having not even a single application running at all.
How Does DRaaS Work?
DRaaS work by hosting and replicating servers using the facilities of a third-party vendor versus the in-house physical location of the company that has ownership of the workload. The third-party group will set in place a disaster recovery plan in case a disaster closes down the site of the client. Companies can buy DRaaS plans using a pay-per-use model or a conventional subscription model that lets them pay only if a disaster happens. The cost and scope of a service solution are different.
Companies must assess the possible DRaaS providers based on their unique budgets and needs. DRaaS could save companies a lot of cash by getting rid of the need for maintaining and provisioning a company’s very own offsite disaster recovery environment. But there are certain risks.
You won’t have a guarantee that an IT consulting and DRaaS provider would be able to fulfill the agreed-upon RTO in case the provider, as well as the client, are impacted by the exact same natural disaster like an earthquake or hurricane. Different IT outsourcing companies follow different policies when it comes to prioritizing which clients to provide help to first especially when a large disaster happens in a region or lets clients do their own disaster recovery testing.
A lot of companies with lean IT teams just cannot afford to spend time to research, execute, and thoroughly test their disaster recovery plans. Disaster recovery-as-a-service eliminates the burden of disaster planning and hands it over to the IT service providers instead.
