Understanding the hybrid cloud Most organizations that adopt a cloud-computing strategy discover that a hybrid approach fits well into their IT strategy. A hybrid cloud is an environment that utilizes both private and public cloud services to meet a business need. This environment allows a customer to make use of a combination of resources at the same time through a consistent set of services. For example, a business process may copy the results of a business transaction from a private environment into a public service, such as a sales automation SaaS environment. Through automation, this process can be executed according to best practices and in adherence with compliance rules. In some situations, a process may be established that requires data from a SaaS application to be physically stored in a private cloud within a particular country. The hybrid cloud is a single service that’s deployment agnostic depending on the needs of the business. Well-designed management tools need to be in place to ensure that the hybrid environment works well to support the business objectives.
