+The **Cloud** refers to servers located worldwide that are accessed over the Internet, and the software and databases that run on those servers.
+
+Instead of storing data or running programs on a local computer or server, users can access cloud resources to perform tasks: this is known as {{glossary("Cloud computing")}}.
+
+### Key features of the cloud
+
+- Remote Access: Data and services are accessed remotely.
+- Scalability: Resources can be scaled up or down based on demand.
+- Availability: Services and data are typically accessible from anywhere with internet access.

+
+**Cloud computing** refers to the on-demand delivery of a wide range of computing services such as servers, storage, databases, networking, analytics, and intelligence via the Internet — also known as **cloud services**.
+
+This model enables faster innovation, flexible scalability, and significant cost savings. Users can use cloud-based services through a _pay-as-you-go_ pricing model, ensuring they only pay for what they use, making them highly efficient and adaptable solutions for businesses and individuals alike.
+
+### Cloud Services
+
+Cloud services are infrastructure, platforms, or software that are hosted by third-party providers and made available to users through the internet. Users can access cloud services with nothing more than a computer, operating system, and internet connectivity.
+
+### Cloud Service Providers (CSP)
+
+**Cloud service providers** are companies that provide cloud services, such as Google (Google Cloud Platform), Amazon AWS (Amazon Web Services), and Microsoft (Azure).
+
+### Types of Cloud computing
+
+The three main types of cloud computing are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Each type of cloud computing provides different levels of control, flexibility, and management.
+
+#### Infrastructure as a Service
+
+IaaS provides virtualized computing resources over the internet, including servers, storage, and networking, allowing users to manage their infrastructure. This gives users a high level of flexibility and control over the resources.
+
+- **Use case:** A company needing to scale its server infrastructure rapidly without owning physical servers.
+
+- **Examples:** Amazon Web Services (AWS EC2), Microsoft Azure Virtual Machines, Google Compute Engine (GCE).
+
+#### Platform as a Service
+
+PaaS provides a platform allowing customers to develop, run, and manage applications without worrying about the underlying infrastructure (like servers, storage, and networking).
+
+- **Use case:** A developer who wants to focus on writing code and application logic, without managing servers or operating systems.
+
+- **Examples:** Google App Engine, Microsoft Azure App Service, Heroku, AWS Elastic Beanstalk.
+
+#### Software as a Service
+
+SaaS delivers software applications over the internet, which users can access via a web browser. The underlying infrastructure, platform, and data are all managed by the provider.
+
+- **Use case:** A business using SaaS doesn't need to install or manage software locally. Instead, they access the software (like email, CRM, or collaboration tools) directly from a web browser.
+
+- **Examples:** Google Workspace, Microsoft 365, Slack, Github, ChatGPT.
