You operate development processes, methods and tools in a single and consistent way across all types of cloud environments, including those of other public cloud vendors. And sometimes data residing in the cloud and possibly in a different country is an advantage. But emerging public cloud offerings such as virtual private clouds (VPCs) bring many of the same benefits as private cloud computing without imposing the same cost or management burdens. Hybrid clouds allow data and apps to move between the two environments. This type of storage exists on a remote cloud server and is accessible over the internet under a subscription-based utility billing method where the users pay only for the storage capacity being used. The computing functionality may range from common services such as email, apps and storage to the enterprise-grade OS platform or infrastructure environments used for software development and testing.

For example, hybrid cloud enables a company to keep sensitive data and mission critical legacy applications (which can’t easily be migrated to the cloud) on-premises while leveraging public cloud for SaaS applications, PaaS for rapid deployment of new applications, and IaaS for additional storage or compute capacity on demand. It is basically used by the private individuals which are in need of the infrastructure and the security which is offered by the private clouds. The service may be free, freemium, or subscription-based, charged based on the computing resources consumed.
