Infrastructure as a Service (IaaS)

Overview

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)

Overview

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)
