In a recent survey* of US and UK-based IT decision makers, 60% of respondents said their companies favored a hybrid approach to implementing cloud services.Although public cloud services are relatively easy to implement it seems that because of security concerns, along with a desire to better tailor individual solutions, businesses prefer a mix of cloud-based and on premise storage and software solutions.
Some of the IT specialists who have chosen the pure public cloud route have found themselves in situations where they need to fit square pegs into round holes to meet business needs.
The multi-tenanted nature of public cloud services can create headaches in terms of security and compliance, especially in business sectors where confidentiality, security and non-tampering of data is paramount.
Hybrid cloud offers the best of both worlds. Companies are still free to pick and choose public cloud services that work for them, but can also keep certain parts of their infrastructure completely private, either in the cloud or on-premise.
As an example, a company may be quite happy to use a hosted Exchange provider for email, and to use cloud services for system monitoring and other IT management tasks, but prefer to keep database data and sensitive files on a single-tenant private cloud system, which is physically segregated from other company’s servers at the datacenter.
While the deployment of such a hybrid system requires a little more thought and consideration, it leaves the business with a system that meets their exact requirements. In addition, it will probably result in fewer difficult questions during the next compliance audit.
Protecting your business
Regardless of exactly how an organisation builds their cloud provision, there are certain things they’re going to need to keep their systems secure and operating efficiently. Using public cloud services for these day-to-day operational tasks can make life much easier for the IT department, who can take advantage of such services to centrally manage much of their day-to-day work.
