Cloud computing platforms are broadly categorized into Infrastructure as a Service $($IaaS$),$ Platform as a Service $($PaaS$),$ and Software as a Service $($SaaS$).$ IaaS offers virtualized computing resources such as servers, storage, and networking infrastructure on a pay$-$as$-$you$-$go basis, giving users full control over their software environments. PaaS provides a higher level of abstraction by offering a complete development and runtime environment for building and deploying applications without managing underlying infrastructure. SaaS delivers software applications over the internet on a subscription basis, eliminating the need for users to install or maintain software locally. Each type of cloud computing platform caters to different needs and preferences, with IaaS offering flexibility and control, PaaS streamlining application development and deployment, and SaaS simplifying software access and management. Ultimately, the choice of platform depends on factors such as desired level of control, complexity, and management overhead.
