Hybrid Cloud: A New Paradigm in Cloud Computing

Hybrid cloud computing is basically a combination of cloud computing with on‐premise resources to provide work portability, load distribution, and security. Hybrid cloud may include one public and one private cloud, or it may contain two or more private clouds or may have two or more public clouds depending on the requirement. Public clouds are generally provided by third party vendors like Amazon, Google, and Microsoft. These clouds traditionally ran off premise and provide services through internet. Whereas private clouds also offer computing services to selected user either over the internet or within a private internal network and conventionally ran on‐premise. But this scenario is changing nowadays. Earlier distinction between private and public clouds can be done on the location and ownership information, but currently, public clouds are running in on‐premise data centers of customer and private clouds are constructed on off premise rented, vendor‐owned data centers as well. So, the architecture is becoming complex. Hybrid cloud reduces the potential exposure of sensitive or crucial data from the public while keeping non‐sensitive data into the cloud. Thus, secure access to data while enjoying attractive services of the public cloud is the key factor in hybrid cloud. Here, we have done a survey on hybrid cloud as it is one of the most promising areas in cloud computing, discuss all insight details. Security issues and measures in hybrid cloud are also discussed along with the use of artificial intelligence. We do not intend to propose any new findings rather we will figure out some of future research directions.
