A. B. C. D.Correct Answer: B.
The service model that offers application deployment and development tools as a service is Platform as a Service (PaaS).
PaaS is a cloud computing service model that provides a platform for developers to build, deploy, and manage applications without the complexity of infrastructure management. PaaS offers a complete development and deployment environment in the cloud, including the operating system, programming language execution environment, web server, database, and other tools required to develop, test, and deploy applications.
PaaS is a step up from IaaS, which only provides the infrastructure resources such as servers, storage, and networking, allowing users to build their own applications on top of the infrastructure. PaaS offers a more comprehensive service, providing not only the infrastructure but also the tools and frameworks needed to build and deploy applications.
Product as a Service (PaaS) is not a recognized cloud service model, it's likely a misnomer or a mistake, so option C can be eliminated.
Software as a Service (SaaS) is a cloud service model that delivers software applications over the internet. SaaS offers ready-to-use software applications that are hosted and managed by a third-party provider. Users can access these applications from anywhere with an internet connection, without needing to install them on their local machines.
In summary, PaaS is the cloud service model that offers application deployment and development tools as a service, while IaaS provides infrastructure resources, and SaaS provides ready-to-use software applications.
