Which of the following is a definition of Hybrid Cloud?
An architecture that uses a combination of services running in public and private data centers, only including data centers from the same cloud provider.
A cloud native architecture that uses a combination of services running in public clouds, excluding data centers in different availability zones.
A cloud native architecture that uses a combination of services running in different public and private clouds, including on-premises data centers.
An architecture that uses a combination of services running in public and private data centers, excluding serverless functions.
Explicación Oficial / Explicaciones de la Comunidad
A hybrid cloud is a cloud computing environment that combines a public cloud, a private cloud, and on-premises infrastructure to create a single, flexible, and cost-effective IT infrastructure. The correct definition is: "A cloud native architecture that uses a combination of services running in different public and private clouds, including on-premises data centers." This definition accurately captures the essence of hybrid cloud: it integrates multiple distinct cloud environments (public and private) and includes on-premises data centers, allowing data and applications to be shared between them.
How it Works
Hybrid cloud architecture enables organizations to leverage the scalability and cost-efficiency of public clouds for non-sensitive workloads while keeping critical data and applications in a private cloud or on-premises data center for security and compliance. It often involves orchestration, management, and application portability across environments using technologies like Kubernetes, VPNs, and APIs.
Why the Correct Definition is Right
The correct definition explicitly mentions "different public and private clouds" and "on-premises data centers," which are key components of a hybrid cloud. It emphasizes that the architecture is cloud native, meaning it is designed to take full advantage of cloud computing models, and it includes on-premises infrastructure, which is a hallmark of hybrid deployments.
Why the Incorrect Definitions are Wrong
- The definition that restricts to "data centers from the same cloud provider" is incorrect because hybrid cloud can involve multiple cloud providers (multi-cloud) and is not limited to a single vendor.
- The definition that excludes "data centers in different availability zones" is incorrect because hybrid cloud can span multiple availability zones and regions; the key distinction is the mix of public and private environments, not the exclusion of zones.
- The definition that excludes "serverless functions" is incorrect because hybrid cloud can include serverless computing; the exclusion of serverless functions is arbitrary and not part of the standard definition of hybrid cloud.
