SaaS stands for Software as a Service, which is a cloud service offering that allows customers to access a web application that is being hosted, managed, and maintained by a cloud service provider. SaaS applications are typically accessed through a web browser or a mobile app, and the customers do not need to install, update, or maintain any software or hardware on their own. SaaS applications can provide various benefits, such as lower upfront costs, faster deployment, scalability, and automatic updates. Some examples of SaaS applications are Gmail, Salesforce, Zoom, and Netflix123.

IaC stands for Infrastructure as Code, which is a method of provisioning and managing cloud resources using code or scripts, rather than manual processes or graphical user interfaces. IaC can help automate and standardize the deployment and configuration of cloud infrastructure, as well as improve consistency, reliability, and security. IaC is not a cloud service offering, but rather a technique or practice that can be used with different cloud service models, such as IaaS or PaaS45.

IaaS stands for Infrastructure as a Service, which is a cloud service offering that provides customers with access to virtualized computing resources, such as servers, storage, networks, and operating systems. IaaS customers can rent or lease these resources from a cloud service provider, and have full control over their configuration and management. IaaS customers are responsible for installing, updating, and maintaining their own applications and middleware on top of the cloud infrastructure. IaaS can provide various benefits, such as flexibility, scalability, cost-effectiveness, and security. Some examples of IaaS providers are Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform .

PaaS stands for Platform as a Service, which is a cloud service offering that provides customers with access to a cloud-based platform that includes the infrastructure, operating system, middleware, and development tools needed to build, deploy, and run applications. PaaS customers can focus on developing and running their own applications, without worrying about the underlying cloud infrastructure or software. PaaS can provide various benefits, such as faster development, scalability, compatibility, and security. Some examples of PaaS providers are Heroku, AWS Elastic Beanstalk, and Google App Engine .
