Hybrid cloud is a computing environment that connects a company’s on-premises private cloud services and third-party public cloud into a single, flexible infrastructure for running the organization’s applications and workloads.
The principle behind hybrid cloud is that its mix of public and private cloud resources—with a level of orchestration between them—gives an organization the flexibility to choose the optimal cloud for each application or workload (and to move workloads freely between the two clouds as circumstances change). This enables the organization to meet its technical and business objectives more effectively and cost-efficiently than it could with public or private cloud alone.
The benefits of hybrid cloud are easier to understand once you know more about the capabilities, limitations, and uses of private and public clouds.
Benefits of hybrid cloud
Security and compliance
Hybrid cloud lets your organization deploy highly regulated or otherwise sensitive workloads in private cloud, while still being able to deploy less-sensitive workloads to public cloud services.
Scalability and resilience
You can’t always predict when workload traffic will spike, and even when you can predict spikes, you can’t always afford to purchase additional private cloud capacity for those spikes only. Hybrid cloud lets you scale up quickly, inexpensively, and even automatically using public cloud infrastructure and then scale back down when the surge subsides—all without impacting the other workloads running on your private cloud.
Resource optimization and cost saving
Hybrid cloud gives your IT more options and flexibility for deploying workloads in a way that makes the best use of your on-premises investments and your overall infrastructure budget. It also allows you to change that deployment in response to changing workloads or new opportunities.
