Cloud Disaster Recovery also familiar to known as Cloud DR is a combination of strategies and services that are intended to back up the process of data, application, and other resources to the public cloud or dedicated service providers. When any kind of disaster occurs, the data that is affected, or application, or other resources that can be easily restored to the local data center– or cloud provider– and with that resume to the normal operational work for the enterprise.
It is not at all wrong in saying that in todays’ modern-day organization’s data is one of the most valuable and important assets. The loss of data that occurs here can result in irreversible damage to the business. This further includes the loss of productivity, revenue, reputation, and even to the clients and customers. Moreover, the prediction of the occurrence of the disaster is hard and along with that is also hard to say how serious the impact will be.
However, one thing that we can control here is the way the response is been shared with the disaster, and with that also how successfully we can have it organized to recover from it. Get to discover post how you can use disaster recovery in cloud computing for your benefit. Also, the process of cloud DR has its own importance as that compared to traditional DR strategies.
- Pay-as-you-go: It is that the organizations that are being deployed with the facility of DIY, DR facilities, are being faced by an significant cost of capital. This is also working when it is engaging managed colocation providers for off-site DR services. It is often locked into the organizations that are on a long-term service agreement basis. One of the major advantages of cloud disaster recovery service is that you need to pay the amount on the go and also a recurring monthly charge which is for the resources and the services being used. As resources are added or removed, the payments change accordingly.
It is in effect, that the service of the cloud model delivery turns out to be having upfront capital costs that which is into recurring operational expenses. However, it is that the cloud providers do offer frequent discounts for long-term resource commitments, which is more attractive to larger organizations and that with static DR needs.
- Flexibility and Scalability: The approach of traditional DR is usually implemented in local or remote data centers. This is thus imposed with the limitations and thus makes the process flexible and scalable. The business had to buy the servers, storage, network gear, and software tools needed for DR, and then design, test, and maintain the infrastructure needed to handle DR operations — substantially more if the DR was directed to a second data center. This typically represented a major capital and recurring expense for the business.
Cloud DR options, such as public cloud services and disaster recovery as a service (DRaaS) providers, can deliver enormous amounts of resources on-demand, enabling businesses to engage as many resources as necessary — usually through a self-service portal — and then adjust those resources when business demands change, such as when new workloads are added or old workloads and data are retired.
- High-reliability and geo-redundancy: One essential and important hallmark of a cloud provider is a global footprint, ensuring multiple data centers to support users across major global geopolitical regions. It is that the cloud providers always make sure that the Cloud providers use this to improve service reliability and ensure redundancy. Businesses and industries can and will readily take advantage of geo-redundancy to place DR resources in another region — or even multiple regions — to maximize availability. The quintessential off-site DR scenario is a natural trait of the cloud.
- Easy testing and fast recovery: Here comes another benefit of the service. This is the Cloud workloads that routinely operate with VMs, and with that making it easy to copy VM image files to in-house test servers to validate workload availability without affecting production workloads. In addition, businesses can select high bandwidth and fast disk I/O (input/output) options to optimize data transfer speeds to meet recovery time objective (RTO) requirements. However, data transfers from cloud providers impose costs, so testing should be performed with those data movement — cloud data egress — costs in mind.
Above mentioned are some of the core benefits of the services. Now let us take the discussion further and check on the difference between Cloud DR vs Traditional DR.
Cloud DR v/s Traditional DR
Cloud-based DR services and DRaaS offerings can provide cost benefits, flexibility and scalability, geo-redundancy, and fast recovery. But cloud DR might not be appropriate for all organizations or circumstances. Consider some of the situations where more traditional DR approaches might be beneficial, even essential, for the business.
- Compliance requirements: The demand for cloud services is increasing day-by-day and with these industries and enterprises are accepting the service with all its open hands. It is a usage where well-established regulatory oversight is required such as HIPAA (Health Insurance Portability and Accountability Act) and PCI DSS. However, some organizations might still face prohibitions when storing certain sensitive data outside of an immediate data center — or in any resource or infrastructure that isn’t under the organization’s direct control, such as a third-party infrastructure like a public cloud. In these cases, the business might be obligated to implement local or owned off-site DR to satisfy security and compliance demands.
- Limited connectivity. Cloud resources and services depend on WAN connectivity such as the internet. DR use cases put a premium on connectivity because a reliable, high-bandwidth connection is critical to quick uploads/synchronization and fast recovery. Although reliable, high-bandwidth connectivity is common in global urban and most suburban areas, it’s hardly universal. Remote installations such as edge computing sites often exist — at least, in part — because of limited connectivity, so it might make perfect sense to implement data backups, workload snapshots, and other DR techniques at local sites where connectivity is questionable. Otherwise, the business risks data loss and problematic RTOs.
- Use existing investments. DR needs have been around much longer than cloud services, and legacy DR installations — especially, in larger businesses or where costs are still being amortized — might not be so easily displaced by newer cloud DR offerings. That is, a business that already owns the building, servers, storage, and other resources might not be anxious to abandon that investment. In these cases, the business can adopt cloud DR more slowly and cautiously, systematically adding workloads to the cloud DR provider as an avenue of routine technology refresh, rather than spending another round of capital.
