Cloud computing is a broad term that encompasses a variety of technologies and services. There are three main types of cloud computing deployment models: public cloud, private cloud, and hybrid cloud.

Public clouds are owned and run by third-party cloud service providers like Google Cloud, and they deliver resources such as compute, storage, network, develop-and-deploy environments, and applications over the internet. Private clouds, on the other hand, are built, run, and used by a single organization, typically located on-premises. They provide greater control, customization, and data security but come with similar costs and resource limitations associated with traditional IT environments. Hybrid clouds are environments that mix at least one private computing environment (traditional IT infrastructure or private cloud, including edge) with one or more public clouds. They allow you to leverage the resources and services from different computing environments and choose which is the most optimal for the workloads.

Within these deployment models, there are four main services: infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS), and serverless computing. IaaS provides virtualized computing resources such as servers, storage, and networking to users. PaaS offers a platform for developing, testing, and deploying applications. SaaS provides software applications that are hosted and delivered over the internet. Serverless computing allows developers to build and run applications without having to manage the underlying infrastructure.

There are many other cloud technologies and applications available, and the field is constantly evolving. Cloud computing has become an essential tool for businesses and individuals who need to store, manage, and access data in a flexible and scalable way.
