3.2 Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud computing has transformed how organizations deploy and manage IT resources, moving from traditional on-premises infrastructure to more flexible, scalable, and often cost-effective cloud-based solutions. Provide a detailed explanation of the different deployment models, including their characteristics, advantages, and limitations. Additionally, illustrate how each model can be applied in various business scenarios, highlighting the factors that influence their selection and implementation.(20)
