To move some applications to the cloud, organizations may be best served by adopting a hybrid model, which combines multiple types of cloud or conventional infrastructure. Hybrid-cloud models include:
Own the base, rent the spike: Under this model, normal day-to-day workloads run on in-house IT infrastructure (which can be either conventional or a private cloud). Off-premises hosted-cloud resources are used only during periods of peak demand to maintain service levels to users.
Cloud as firewall: Under this model, an off-premises cloud environment is used to run customer-facing processes that may support web or mobile applications. Back-end application components such as databases and transaction processing systems remain in-house.
Compliance segmentation: Here, data is split between in-house and off-premises environments. This enables compliance with data-related regulatory mandates, while still allowing the benefits of cloud computing to be applied where appropriate.
