The manner in which the Cloud computing has turned the current scenario of businesses could be termed as drastic, unexpected and lovable. Cloud computing is something that’s economical and yet fast and uncomplicated. That’s what accounts for much of the high-tech buzz these days about it. Although this has led to award it a share which is more than its fair share leading to unintended consequence overshadowing its real utility.
The reason why cloud computing is preferred for disaster recovery is that it save the secondary cost of secondary infra that’s idling for most of the time. Plus this alternate usage is well suited for DR. Having DR site in is the cloud reduces the need for data center space, IT infrastructure and IT resources, which leads to significant cost reductions, enabling smaller companies to deploy disaster recovery options that were previously only found in larger enterprises.
Still disaster recovery in the cloud isn’t a perfect solution due to its shortcomings which needs to be explored before you ventures into it. And when you are determinant of the fact that you need a DR strategy, you need to get the best for your organization. The 6 key steps to implement cloud-based disaster recovery:
What’s your need?
The first step to know what would suit you best is to determine your requirements precisely. You just can’t neglect thing as it may all end up with a messed up recovery strategy. Although evaluations of one’s organization may look simple, it is a major factor that helps you determine the infrastructure and configuration that you would have to put to facilitate a cloud-based data recovery or protection. The need of your organization may depend on the type of cloud based data protection they are o provide. Mostly organizations use cloud storage as part of a disk-to-disk-to-cloud backup solution. The primary backups remain onsite, but they’re replicated to cloud storage where they’ll be protected from things that could disable a data center, such as a fire or flood. While some other firms replicate entire virtual machines (VMs) to the cloud so they can be spun up and hosted in the cloud if it isn’t possible to continue to host the VMs in the local data center.
Who’s your cloud provider?
Determination of your needs invites you to determine the cloud provider that could accommodate your need. When some providers allows you to replicate a VM, but won’t host it or provides storage, but little else. If your goal is to build a cloud-based disaster recovery site, you’ll need to find a cloud service provider that offers the specific capabilities you need.
What’s your budget?
Next essential thing is cost estimation of cloud-based disaster recovery which is dependent on the following factors:
Monthly subscription fee
Amount of Internet bandwidth used
Consumed storage space
Number of virtual processor
A bandwidth management strategy
It allow you to limit the overall bandwidth that the data-copying app consumes and may let you increase that limit during off-peak hours. Some organizations may indulge in using quality of service to reserve bandwidth for cloud backups and other bandwidth-intensive services which ensures that each Internet-based service receives the bandwidth it needs without consuming an excessive amount of the available bandwidth.
What’s your logistical requirements?
Logistics planned vary considerably depending upon your company’s existing infrastructure, the cloud service being used and the desired end result. For example, if a company uses cloud solely for its storage capabilities, there will only be a minimal amount of logistical planning that will have to take place. But when the organizations chooses perform full-blown failovers to the cloud will need to take a number of considerations into account.
When to use VM replication?
This is an alternative technique for using the cloud for disaster recovery. If an organization uses this approach, they must determine what they hope to gain from the replication process. To be usable, the VMs will need IP addresses that are local to the cloud-based virtual network subnet on which they will reside during a failover. DNS record modifications are required so the virtual server can be found when it’s running in the cloud.
