Cloud deployment models refer to the various ways in which cloud services can be delivered and managed. The main types include Public Cloud, where services are offered over the internet to multiple users; Private Cloud, which is dedicated to a single organization; and Hybrid Cloud, which combines both public and private clouds for greater flexibility. Each model has its own advantages. Public Clouds are cost-effective and scalable, while Private Clouds offer enhanced security and control. Hybrid Clouds allow businesses to balance workloads between both environments, optimizing resources and meeting specific needs while maintaining data privacy.
