Cloud Deployment Models: Explaining and Comparing the 5 Main Models

Cloud deployment models define where servers are located and who manages them. These models include public clouds (owned by a third-party provider), private clouds (dedicated to one user or organization), hybrid clouds (combination of public and private clouds), multi-clouds (use of multiple cloud providers), and community clouds (for specific communities). Each model has its advantages and disadvantages, depending on factors such as cost, scalability, security, and compliance requirements. Additionally, there are three main service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), which determine the level of control and management provided by cloud providers.
