Cloud Computing Model	Description
Infrastructure as a Service (IaaS)	Provides virtualized computing resources over the internet
Platform as a Service (PaaS)	Provides a platform for developing and deploying applications
Software as a Service (SaaS)	Provides software applications over the internet

The Three Main Types of Cloud Services

Cloud computing services are divided into three main types: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS)⁴. Each type offers different levels of control and flexibility. This allows users to pick the best services for their needs. The first source states that IaaS, PaaS, and SaaS are the main cloud service types⁴.

Here's what each type offers:

• Infrastructure as a Service (IaaS): gives users on-demand access to resources like storage and computing power⁴.
• Platform as a Service (PaaS): provides a full environment for developing and deploying applications⁵.
• Software as a Service (SaaS): offers software applications over the internet, so you don't need to install or maintain them locally⁴.

Businesses and individuals widely use these cloud services. They are provided by big names like Amazon Web Services, Google Cloud, IBM Cloud, and Microsoft Azure⁵. Cloud technology is popular for its scalability, flexibility, and cost savings. It's a key part of today's computing and technology⁴.

In summary, knowing about the different cloud services is key to choosing the right ones. It helps both individuals and businesses to benefit from cloud technology⁵.

Major Cloud Computing Service Models

Cloud computing solutions offer a range of service models for businesses and individuals. The main models include infrastructure as a service, platform as a service, and software as a service⁶. These models give users options for deploying and managing applications and services.

Infrastructure as a service (IaaS) gives users on-demand access to computing power and storage. This model lets businesses upgrade their infrastructure quickly without needing physical space⁷. Platform as a service (PaaS) provides a complete environment for application development and deployment, including middleware and cloud databases⁶. Software as a service (SaaS) delivers software applications over the internet, eliminating the need for local installation and maintenance⁶.

The benefits of these models include cost savings, enhanced scalability, and increased security. Businesses using IaaS save money compared to upgrading in-house resources⁷. PaaS solutions help reduce development time-to-market⁷. SaaS offerings allow users to access applications at any time from any internet connection⁷.

Cloud computing providers offer various cloud services, including public, private, and hybrid clouds. Public clouds provide resources like compute, storage, and applications over the internet⁶. Private clouds are on-premises and offer more control, customization, and data security than public clouds⁶. Hybrid clouds combine at least one private computing environment with one or more public clouds⁶.
