Which type of service provides developer tools over an internet connection?

The correct choice is a service model that specifically focuses on delivering a platform for developers to build, deploy, and manage applications without the complexity of maintaining the underlying infrastructure. In this model, developers have access to a variety of tools and services via the internet, allowing them to focus on writing code and developing applications rather than dealing with server management, storage, networking, and other elements related to the infrastructure.

This service typically includes functionalities such as application hosts, development frameworks, and database management systems, which are essential for simplifying the development process. The ability to scale resources easily and integrate with various development tools creates an efficient environment for continuous application delivery and innovation.

In contrast, other service models do not specifically cater to the needs of developers in the same way. For example, while software as a service delivers fully functional applications over the internet, it does not provide the tools necessary for development. Infrastructure as a service offers virtualized computing resources but does not focus on the development tools; it provides the hardware aspect of a solution instead. Anything as a service is a broader category that encompasses all types of services delivered over the internet, but it is not specific to developer tools.
