Function, Feature, and Design of Cloud Computing Virtual Machines(Combined)

Cloud computing is an on-demand service that provides data storage, servers, networking, and software in a virtualized environment. Organizations can access, manage, and store data off-site using the internet. It allows companies to be more efficient, agile, and scalable while reducing costs. There are different types of cloud computing services. They include:

• Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet. Customers get physical and virtual servers, storage, networks, and operating systems. The service is scalable and flexible, allowing businesses to rent any resources they need. Examples include Google Compute Engine, Amazon Web Services (AWS), and Microsoft Azure.
• Platform as a Service (PaaS): Offers hardware and software tools over the internet. The tools are usually needed for application development and are available on a subscription basis. It provides a platform for developers to create applications without managing the underlying infrastructure. Examples include Heroku, Google App Engine, and Microsoft Azure App Service.
• Software as a Service (SaaS): Delivers software applications over the internet. Users access the software through an internet browser without downloads or installations. SaaS applications are hosted on the cloud, and data is stored in the cloud. Examples include Google Workspace, Salesforce, and Microsoft 365.

Cloud computing has deployment models. These models determine the environment in which cloud computing operates. They include:

• Public cloud: A public cloud model provides services to multiple customers. It is owned by third-party cloud service providers. These providers offer resources such as servers and storage to anyone willing to pay for them. Examples include Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform.
• Private cloud: A private cloud model provides services to a single customer only. A private cloud can exist physically on its data center or be hosted off-premises.
