It is the most cost-efficient cloud model as it reduces the development and maintenance costs of the companies. The pay-as-you-go option by the cloud service providers requires the companies to pay for what they use in the cloud, nothing more, nothing less.
Generally, the private cloud computing system is developed and maintained by a single organization with sole authority over the infrastructure. Huge enterprises and government organizations utilize this cloud model to avoid security incidents. It helps implement strict security and compliance measures and control computing resources. Private can be in both on-premise or on a third-party cloud server.
It is a combination of private and public cloud infrastructure that facilitates organizations to utilize the benefits of both models. Sometimes, the same organization can use the public cloud for non-sensitive workloads like emails and file storage while securing critical applications and data on a private cloud. A major advantage of this model is that it allows seamless data transfer between public and private cloud systems. Hybrid clouds are becoming popular as it has the benefits of both scalability for public data and security for sensitive data.
It is a deployment model in which several cloud infrastructures are integrated to address the needs of a specific community, industry, or business. Thus, the community cloud is shared by organizations with similar needs and interests. It can be owned and managed by third-party vendors or the community in the public cloud or on-premise infrastructure.
Organizations can use multiple cloud features from different vendors to meet business requirements in the multi-cloud model. It can also use a combination of public and private clouds for operational convenience. Thus, all the multi-cloud can be hybrid clouds, but all hybrid clouds cannot be multi-clouds. Multi-clouds reduce the dependency on a single vendor for all business operations, facilitating scalability, flexibility, and redundancy. Organizations can leverage the best features of different cloud providers to customize their cloud structure.
