A hybrid cloud refers to a storage and computing infrastructure composed of a mixture of private cloud services, a public cloud, and/or on-premises infrastructure. The various resources are orchestrated to work together as seamlessly as possible.
With a hybrid cloud, an organization has the opportunity to obtain the “best of both worlds.” They can use cloud services where it works best while keeping certain operations within their own on-premises network infrastructure or inside a private cloud. This opens the way for greater flexibility. There are several types of hybrid clouds, and regardless of the solution you choose, it is important to ensure the security of your hybrid cloud environment.
The concept underlying hybrid cloud systems is that they are a combination of public and private cloud tools. This enables an organization to enhance their flexibility as they decide the best deployment of their storage and computing power. If, for example, one application requires more computing power than another and the on-premises data center has more resources than the cloud side, the company has the freedom to move that operation into their in-house data center—or vice versa.
A hybrid cloud system may also incorporate Infrastructure-as-a-Service (IaaS). With IaaS, you essentially purchase an off-premises computer, including a central processing unit (CPU), hard drive space, and random access memory (RAM). You can be selective regarding the parameters of your setup, choosing the features you need to achieve business objectives while not overspending on features that would be redundant or excessive.
When linking the facets of a hybrid cloud, resources can be connected using a local-area network (LAN) or a wide-area network (WAN). You can also use a virtual private network (VPN) or application programming interface (API). The various resources and environments are controlled using management software, which enables the IT team to both keep the hybrid cloud system secure and adapt its function to best fit the needs of the organization.
