But just as we were getting comfortable with this, enterprises and startups everywhere have started promoting the hybrid cloud. So what exactly is this hybrid cloud!?
However purely storing all data on a cloud still has lots of disadvantages (at least for now)- cloud access tends to be slower, lacks essential security features, comes with high bandwidth requirements, and requires sharing proprietary data with a third party. Hence most businesses are reluctant to completely rely on cloud storage.
The Hybrid Cloud approach combines the best of both worlds- on-prem storage (which is often referred to as the private cloud) and public cloud storage. Enterprises typically classify their data as hot and cold data and to understand the hybrid cloud approach we need to understand the differences between these two types of data.
The Hybrid Cloud is a combined solution that provides enterprises the ability to use on-prem (mostly traditional data storage arrays) to store hot data and cloud storage to store cold data. The on-prem storage provides the necessary security, access times, and data services essential for handling hot data. The off-prem cloud storage is slower but provides a cheaper option to store cold data. Today traditional storage companies such as EMC, HP, NetApp, and new emerging upstarts such as Nasuni and Panzura provide customers the ability to implement a hybrid environment for their storage needs.
