The meaning of hybrid cloud and its benefits
Over the years, cloud computing has become the focus of many IT policymakers and large corporations. However, many security concerns have been hesitant in moving data and workloads to popular cloud services.
As the technology of the cloud platform has become available to be widely deployed within many organizations, a new form of cloud computing has begun to emerge to improve security and increase the ability to meet needs of diverse information processing. This is hybrid cloud.
What is hybrid cloud?
Currently, there is a lot of confusion around the true concept of hybrid cloud. "Hybrid cloud term seems to have been created by service providers rather than customers," said Forrester Research’s analyst Dave Bartoletti. In addition, Carl Brook, an analyst from 451 Research, agrees that the hybrid cloud term is misleading and has excessive advertisements about it.
"What customers want to do is simply using different clouds," Bartoletti said. From conversations with customers, Forrester Research has come up with a hybrid cloud definition: "One or more public clouds are connected to something in the data center. You could be a private cloud or a traditional data center."
By this definition, hybrid cloud is a combination of cloud computing platforms, including one or more public cloud service providers (like Amazon or Google) with an internal cloud platform designed for an organization or private IT infrastructure.

However, 451 Research has a slightly different definition. According to them, the definition of hybrid cloud is: "Two or more different cloud computing environments are used in combination to solve a workload or an application through a single management facility."
The benefits of hybrid cloud
The most obvious benefit of hybrid cloud is that it only needs to pay for additional computing time when it is really needed. Accordingly, for businesses that need large amounts of computing at certain times of the year (such as the tax season), they can shift to utilizing public clouds in hybrid cloud systems.
"The hybrid cloud allows you to choose the right cloud for your workload," Bartoletti said. "It does not limit you."
In addition, building a hybrid cloud that is directly linked to the private cloud will significantly reduce data access time and latency compared to using the public cloud.
Another benefit of the hybrid cloud model is that it creates an on-premises computing infrastructure to support the workload. In addition, cloud hybridization provides a backup plan for enterprises to use the public cloud if the workload exceeds the private cloud capacity.
Finally, building hybrid cloud also allows for flexibility in server design. This allows companies to have more options in finding a fast, stable, but low-cost storage solution.
