Cloud Service Models

Infrastructure as a Service (IaaS)


Infrastructure as a Service (IaaS) provides users with virtualized computing resources over the internet, including servers, storage, and networking components. Users have full control over the underlying infrastructure, enabling them to deploy and manage virtual machines, storage volumes, and networks as needed.

Use Cases

IaaS is commonly used for various purposes, such as hosting websites and web applications, running development and testing environments, and supporting data analytics workloads.

Platform as a Service (PaaS)


Platform as a Service (PaaS) offers a higher level of abstraction compared to IaaS, providing a platform for developing, deploying, and managing applications without the complexity of managing underlying infrastructure components. PaaS environments typically include tools, frameworks, and middleware for application development and deployment.

Use Cases

PaaS is well-suited for application development and deployment scenarios, enabling developers to focus on writing code without worrying about infrastructure management. It is commonly used for building web and mobile applications, as well as deploying software-as-a-service (SaaS) solutions.

Software as a Service (SaaS)


Software as a Service (SaaS) delivers applications over the internet on a subscription basis, eliminating the need for users to install, maintain, and update software locally. SaaS applications are accessed through web browsers or thin clients, with the provider handling all aspects of software delivery and maintenance.

Use Cases

SaaS is prevalent across various domains, including productivity software (e.g., email, document collaboration), customer relationship management (CRM), enterprise resource planning (ERP), and communication tools (e.g., video conferencing, messaging).
