There are three main versions of cloud computing:
1. Public Cloud: A third-party provider delivers cloud services over the internet, available to anyone. Examples include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).
2. Private Cloud: A single organization owns and manages a cloud environment, typically hosted on-premises or in a data center. This version offers more control and security.
3. Hybrid Cloud: A combination of public and private clouds, allowing data and applications to be shared between them. This version offers flexibility and scalability.
Additionally, there are other variations, including:
- Community Cloud: A shared cloud environment for specific industries or communities.
- Edge Cloud: A distributed cloud architecture for IoT devices and real-time processing.
- Multi-Cloud: Using multiple cloud services from different providers to avoid vendor lock-in.
Each version has its advantages and use cases, depending on the organization's needs and goals.
