Hybrid cloud hosting is a model that allows organizations to provision dedicated servers and storage and shared cloud servers and storage on the same network. A hybrid cloud consists of a minimum of one private cloud (also known as an internal cloud) and one public cloud (or external cloud).
With hybrid cloud hosting, companies can keep mission-critical applications and information in-house behind the corporate firewall on dedicated servers safe from third-party access, while applications with fewer security concerns are available on the shared web platform.
Companies can also reduce their storage costs using hybrid cloud hosting because they can scale shared server access up or back as needed, which means they do not have to pay for unused capacity.
Organizations will need to consider the following points in any service-level agreement (SLA) they sign with a cloud storage provider: high-availability (HA) failover contingencies, data throughput, recovery point objective (RPO) and recovery time objective (RTO).
