Multi-Cloud Disaster Recovery is Taking Shape: Three Things to Know
The emergence of hybrid cloud models (think Eze Private Cloud + Microsoft Cloud) are allowing firms to get creative in their disaster recovery designs. Here are three reasons a multi-cloud approach to disaster recovery is appealing to some firms:
Match Services and Applications to the Right Cloud Platform
The best disaster recovery strategies are based on careful internal assessments, including application prioritization. When it comes time to configure disaster recovery solutions, this assessment helps firms prioritize which applications require consistent availability and which ones need less persistent support. A firm might opt for dedicated high-performance disaster recovery for mission-critical applications, while selecting a lower-cost option for non-critical applications.
However, businesses with private cloud-only or public cloud-only disaster recovery solutions sometimes encounter difficulties when navigating this process. Companies reliant on the former technology might find themselves spending significant amounts protecting non-mission critical applications, while those with public cloud only may sacrifice performance, security and ease-of-use.
With the hybrid cloud-based disaster recovery strategy, these are non-issues. Firms can easily move less-demanding systems into a public cloud environment and place mission-critical applications, which require constant updates and are subject to ambitious recovery point and time objectives, into a trusted private cloud environment.
A cloud platform will be more scalable than what an individual firm can support themselves as it can be difficult to manage budgets, the procurement process and maintain the appropriate overhead to maximize the scalability of their own infrastructure. With the cloud those decisions are no longer a concern since there is almost limitless scalability built in.
The private cloud often has benefits relative to connectivity. For example the Eze Private Cloud has direct connectivity to many third parties financial services typically use. This can be a cost savings from having to setup these connections. The Eze Private Cloud also facilitates data security and control. On the flip side, the Microsoft Cloud has almost infinite scalability, which allows firms to easily add resources on demand.
A multi-cloud disaster recovery approach can leverage the above scalability and connectivity benefits as well as deliver greater flexibility. For example, as priorities within the organization change, applications can be moved from one cloud to another easily to maximize performance or cost. With the built in flexibility of the hybrid solution changes can be made on demand.
Employ a One-To-Many Replication Approach
Geographic replication is one of the primary tenets of modern disaster recovery. On the surface, it would seem organizations would be wise to store their data information as far away as possible. However, when there is too much space in between operations and the disaster recovery site, latency can become an issue if the design isn’t correct. When there is too little, well, the entire strategy of geographic replication is rendered useless.
Firms can overcome this problem with hybrid cloud-based disaster recovery strategies, as service providers (such as Eze Castle Integration!) offer numerous data center location options.
More firms are also expressing interest in multiple disaster recovery sites leveraging one to many replication. With one-to-many, firms can replicate data across multiple locations for advanced protection and recovery capabilities. This concept has become more financially feasible with the availability of the hybrid cloud since there are more data centers available and costs can be better balanced.
