The term used to describe when a company chooses to use a third-party vendor to host and administer a critical application is "PaaS," which stands for "Platform as a Service."

PaaS is a type of cloud computing model where a third-party vendor provides a platform for customers to develop, run, and manage their own applications without having to invest in and maintain their own infrastructure. The vendor manages the underlying infrastructure, including servers, storage, and networking, as well as the operating system, middleware, and runtime environment, leaving the customer to focus on developing and deploying their applications.

In this scenario, the customer is outsourcing the hosting and administration of their critical application to the PaaS provider. This can be beneficial for several reasons, such as reducing costs, improving scalability, and increasing flexibility. The PaaS provider can also handle tasks such as security, backups, and updates, which can relieve the customer of some of the burden of managing their own IT infrastructure.

In contrast, SaaS (Software as a Service) refers to a cloud computing model where a third-party vendor provides access to software applications over the internet, without the need for the customer to install or maintain the software. IaaS (Infrastructure as a Service) refers to a cloud computing model where a third-party vendor provides access to computing resources, such as servers, storage, and networking, over the internet. CASB (Cloud Access Security Broker) refers to a security tool that helps organizations secure their use of cloud services by providing visibility and control over user activity, data, and applications.
