Which layer in the cloud computing architecture provides runtime environment to virtual machines?a.Backend layerb.Service layerc.Runtime Cloudd.Frontend layer

Breakdown of the Problem

We need to identify which layer in cloud computing architecture is responsible for providing the runtime environment for virtual machines.

Relevant Concepts

1. Cloud Computing Layers: Generally, cloud computing architecture is divided into several layers:
   • Frontend Layer: This interacts with the user and consists of client-side web applications.
   • Backend Layer: This contains the services provided by cloud, including databases, and server-side logic.
   • Service Layer: Often associated with the APIs that facilitate communication between the frontend and backend.
   • Runtime Cloud: This specific term can be somewhat vague, but typically relates to platforms like PaaS which provide runtime environments.

Analysis and Detail

• Frontend Layer: Not responsible for providing runtime for virtual machines.
• Backend Layer: This contains the actual infrastructure which can support virtual instances.
• Service Layer: It facilitates the interaction but does not directly provide runtime.
• Runtime Cloud: This is most likely what provides the runtime environment for virtual machines.

Verify and Summarize

Upon analyzing each layer, the "Runtime Cloud" seems the best fit, as it directly indicates providing environments where applications (including virtual machines) run.

Final Answer

c. Runtime Cloud
