There are several types of cloud computing models, each with its own characteristics and use cases. Here are the main types of cloud computing with examples:

1. Public Cloud:
   • Description: Public cloud services are provided by third-party cloud service providers and are available to the general public over the internet.
   • Examples: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, IBM Cloud, Salesforce.
2. Private Cloud:
   • Description: Private clouds are cloud computing resources used exclusively by a single organization, either on-premises or hosted by a third-party provider.
   • Examples: A company hosting its own private cloud infrastructure on-site or a cloud hosted by a provider for a specific organization.
3. Hybrid Cloud:
   • Description: Hybrid cloud is a combination of public and private cloud services, allowing organizations to leverage the benefits of both.
   • Examples: An organization using a public cloud for certain workloads while maintaining a private cloud for more sensitive or regulated data and applications.
4. Community Cloud:
   • Description: Community cloud is a cloud infrastructure shared by several organizations that have similar computing needs, requirements, or concerns (e.g., security, compliance).
   • Examples: A group of healthcare organizations sharing a community cloud to meet regulatory requirements.
5. Multi-Cloud:
   • Description: Multi-cloud refers to the use of two or more public cloud services from different providers, often to avoid vendor lock-in and leverage the unique strengths of each provider.
   • Examples: An organization using AWS for some services, Microsoft Azure for others, and Google Cloud for specific applications.
6. Edge Cloud:
   • Description: Edge cloud refers to the deployment of cloud computing resources closer to the source of data, such as at the edge of a network or in IoT devices, to reduce latency and improve response times.
   • Examples: A smart factory using edge cloud services to process data from sensors and devices in real-time.
