They provide on-demand, internet-based computing resources, ranging from raw virtual hardware to fully managed applications, enabling organizations to lower costs and increase scalability.

- **Infrastructure as a Service (IaaS):** Offers raw computing infrastructure (virtual servers, storage, networking) over the internet. Users manage operating systems, applications, and middleware. Examples include [Amazon Web Services (AWS)](https://www.mindstick.com/blog/63534/amazon-web-services-aws) EC2, [Google Compute Engine](https://cloud.google.com/products/compute), and Microsoft Azure Virtual Machines.
- **Platform as a Service (PaaS):** Provides a cloud-based environment for developers to build, test, and deploy applications without managing the underlying infrastructure. Examples include

[**Key Differences**](https://answers.mindstick.com/qa/113654/explain-the-differences-between-iaas-paas-and-saas-with-example)**:**

- **IaaS:** Highest level of management for the user.
- **PaaS:** Balances management between the provider and user.
- **SaaS:** Lowest level of management for the user (fully managed by the provider).
