Federated hybrid clouds allow businesses to distribute their data in accordance with their priorities while leveraging the full advantage of the cloud.
In spite of the obvious benefits of cloud data storage, many small and medium businesses are hesitant to entrust all of their data to the cloud. Cloud storage offers lower management and support burdens, lower capital expenditure, greater scalability, and increased opportunities for collaboration.
Nevertheless, the cloud is not perfect. Managers worry about availability issues: connectivity problems could bring a business to a standstill if mission critical data was unreachable. Some data is considered too important to entrust to the cloud; in spite of cloud providers’ considerable efforts to ensure the security of data, influencers within businesses have IP, security, and privacy concerns.
Hybrid cloud storage offers a solution that helps businesses resolve their cloud concerns without throwing the baby out with the bathwater.
Not all data is equally important. The majority of data that businesses generate does not need to be accessible constantly. Although most cloud vendors do in fact manage to maintain levels of availability that equal or exceed those of in-house solutions, it’s always possible that a natural disaster will knock out connectivity to the data center and render data unreachable.
To handle “expect the unexpected” scenarios, businesses are implementing hybrid solutions that allow them to leverage the benefits of the cloud while also maintaining data availability. A core set of data that must be consistently available can be kept on-site, with the rest moved up to the cloud. The burden on in-house IT staff and infrastructure is slashed while allowing businesses to be confident that their most important data is kept close by.
In other cases, instead of splitting their data between public and private clouds, businesses are using public cloud storage for backup and redundancy. Maintaining adequate numbers of servers on-site to provide a fully redundant system is wasteful when less expensive replication can be achieved by moving data to the cloud. Additionally, backups should be off-site to be truly effective, and the cloud allows for low-complexity automated off-site backup processes.
The cloud is not an all-or-nothing solution. There are significant business benefits to be reaped from implementations that spread data storage across multiple locations. In many cases, it’s advisable to also use different vendors for maximal redundancy.
An ideal scenario might see essential data held on a private cloud within a business’ firewall and replicated onto a cloud vendor’s platform for backup. Less crucial archival data may be placed with another vendor. Data that needs to be available on a short time scale and integrated with logistics or customer relationship management applications may be stored with yet another vendor. Vendor diversification is a powerful strategy for business continuity.
In that scenario, the company’s IT infrastructure moves beyond the simple private-public split of the hybrid cloud and becomes a true federated cloud. In previous years, maintaining a federated multi-cloud environment would have been more work than it was worth for a small business, but since the advent of cloud marketplaces that allow for the comparison and selection of vendors and the management of federated environments from one interface, redundant federated clouds are well within the reach of small and medium businesses.
