     Cloud Computing is defined as on-demand delivery of computing power like Servers, Storage, Network, Database, and other services over the Internet and the Pay-as-you-go Pricing Model. Cloud Computing Cloud service providers like AWS, Microsoft Azure, GCP, and Alibaba Cloud, would be maintaining their Data Centers which consist of Servers, Network Devices, and Storage Devices. Customers who are utilizing cloud services will be utilizing these services without maintaining and managing them. Data Security and Privacy are also assured by Cloud Service Providers.

As per the National Institute of Standards and Technology (NIST) based on the cloud service operation mode, the Cloud Deployment Models are classified.

  • Hybrid Cloud

    The Cloud Computing services are operating in a combination of two or more distinct cloud models like Public Cloud, Private Cloud, or Community Cloud which remain as unique entities but are bound together by a standardized or proprietary technology that enables data and application portability.

  • Community Cloud

    Exclusive provisioning of Cloud Infrastructure for a specific community from organizations that share a common concern like security requirements, compliance, and policy considerations.
