There will always be challenges in running an enterprise-wide disaster recovery program, but especially with cloud computing becoming a fixture across multiple organizations, management is a must. Julie Knudson wrote on Enterprise Networking Planet that a hybrid cloud landscape doesn't have to be an obstacle in the way of a good disaster recovery plan – it can actually be an asset. She spoke with cloud professional Mathew Lodge, who said utilizing the hybrid environment can make disaster recovery less expensive and improve a company's flexibility.
Enterprises can save money by stopping the duplication of infrastructure while having replication capabilities with the cloud. There may have to be additional considerations for challenges such as configurations and use of disaster recovery at the primary site, Knudson wrote. Cloud professional Bryan Che told her that there will be some differences in the cloud's infrastructure versus the businesses. Configurations will likely be one of the key issues, so portability of workloads into different environments will likely be a big consideration.
Having a large amount of bandwidth to keep the program running will also be essential, according to Lodge, and there are ways to sidestep any widespread issues across the infrastructure that may affect how the company works.
"The first is having very high bandwidth connections and continuous replication of data and applications, so the application and the data that it requires is already at the recovery site," Lodge said, adding that if a large storm is coming, there may be a way to move data in advance without hitting limits."If you've got large amounts of data, rather than ship it over the network, you can ship a physical disc to the cloud provider."
Works similarly to regular backup, just slightly more advanced
TechTarget's Eric Slack wrote that use of a hybrid cloud computing disaster recovery solution will store images just as it would in a regular solution, but in this case it will go to whichever platform can best handle the data at that time.
Recovery after a disaster can be handled in the same way a simple cloud restoration is, Slack said, as users or managed service providers can initiate the process and restart the most critical servers from the backup cloud.
Testing, much like it was in a non-cloud backup solution, will be essential. Slack said this is the area in which most companies fall short, but it should be done regularly.
"DR testing takes time, especially when it involves a remote site, and like backup testing, it can be ignored without an immediate negative consequence," he wrote. "But restarting a VM is a very simple process, one that also confirms the viability of the backup at the same time."
For Slack, there is little question that more organizations will embrace the cloud as an alternative to on-site infrastructure, and backup could very well be the first step to the enterprise cloud. These solutions, with their ease of testing, provide a solution to a very fundamental problem that companies have and should be given a trial run.
