Distinguished service models are available through cloud computing, each of which caters to distinct demands and levels of control. Below are the top three cloud computing service models:

Infrastructure as a Service (IaaS):

The essential building blocks of cloud infrastructure are offered by IaaS. Internet users can lease virtualized computer resources including virtual machines (VMs), storage, and networking hardware. Key features of IaaS:

1. The core operating system, apps, and data are all within user control.
2. freedom to customize the virtual infrastructure and scalability.
3. It is appropriate for businesses who wish to control their own software and apps but delegate hardware management to the cloud provider.

Amazon Web Services (AWS) EC2, Microsoft Azure Virtual Machines, and Google Compute Engine are a few examples of IaaS providers.

Platform as a Service (PaaS):

Developers may design, deploy, and manage applications using the PaaS platform and environment without having to worry about the supporting infrastructure. Key features of PaaS

1. Developers concentrate on writing code and creating applications, and the cloud provider takes care of the underlying infrastructure, such as the hardware, operating systems, and runtime environments.
2. Encourages teamwork and quick application development.
3. Perfect for businesses trying to speed up application development and deployment.

Microsoft Azure App Service, Heroku, and Google App Engine are a few examples of PaaS vendors.

Software as a Service (SaaS):

SaaS is a subscription-based method of delivering software programs via the Internet. There is no installation or upkeep required for users to use these programs using a web browser. Characteristics of SaaS:

1. Completely controlled by the cloud service provider, including security, maintenance, and upgrades.
2. Accessibility through an internet connection from any location.
3. Frequently priced per user or per month.

 A few examples of SaaS applications are Salesforce, Microsoft Office 365, and Dropbox.

There are various specialized models and variants along with these basic service models, and they are:

1. Function as a Service (FaaS) or Serverless Computing
2. Container as a Service (CaaS)
3. Database as a Service (DBaaS)
4. Desktop as a Service (DaaS)

Advantages of Cloud Computing:

Cloud computing provides several benefits to people and organizations in a variety of industries. Below are some of the primary advantages of cloud computing.

Cost-Efficiency.

Users of cloud services can avoid making substantial upfront expenditures by only paying for the resources they actually use due to the pay-as-you-go concept. In addition, cloud providers handle security, software upgrades, and hardware maintenance, relieving organizations of infrastructure upkeep and lowering related expenses.
