To put it simply, hybrid cloud hosting is a solution that uses both local and offsite resources for managing storage. A hybrid cloud consists of a minimum of one private cloud (internal cloud) and one public cloud (external cloud).
The biggest benefit to hybrid cloud hosting is the ability to have data that is accessible both locally and in the cloud. Having data stored in multiple locations gives you redundancy—if there is a disaster, you can go to a local coffee shop and still access all of your data. The advantage of hybrid cloud storage is that you have data stored locally too. If your internet goes down, not everyone has to go to a coffee shop to work. An onsite cloud provides you with in-house security and ensures that you will always have onsite access to your data.
