Cloud Computing Architecture

1. Cloud software stack :- integrated software modules that are developed to perform cloud related operations such as,

   • service catalogue to cloud consumers,
   • provisioning requested resources
   • track cloud resource usage

2. Components of cloud software stack?

   • Portal

     corresponds to end user interactions. Similar to an application on a PC.

   • Meter,

     concretizes service measurement in a cloud computing deployment.

   • Orchestrator,

     coordinates infrastructure resources according to user requests issued on the portal. Similar to an operating system on a PC.

3. Cloud infrastructure:- all the software & hardware that the cloud software stack orchestrates and that can also be used in non-cloud data center environments.

4. The importance of standardization for cloud deployments is because,

   Standardization of hardware, software, processes, and offerings facilitate automation and increase predictability in a cloud computing deployment.

5. Characteristics of RESTful application programs?

   • Uses HTTP or HTTPS,
   • Designed for web services,
   • Follows a request-response model.
