Which of the following cloud-computing concepts describes an application that is hosted on the internet but can be used and configured as needed internally per organization?

## Step1: Understanding the Concepts
### In order to answer this question, we need to understand the different concepts of cloud computing. The main types of cloud computing are: Public cloud, Private cloud, Community cloud, and Hybrid cloud.
## Step2: Defining the Concepts
### Public cloud is a type of cloud computing where services are provided over the public internet and available to anyone who wants to purchase them. Private cloud is a type of cloud computing that delivers similar advantages to public cloud, including flexibility and scalability, but it is limited to a single organization. Community cloud is a collaborative platform that is shared by several organizations from a specific community that can be managed internally. Hybrid cloud is a combination of public, private, and community cloud models. It provides the benefits of multiple deployment models and is the most flexible option.
## Step3: Matching the Concepts with the Question
### The question asks for a cloud-computing concept that describes an application hosted on the internet but can be used and configured as needed internally per organization. This matches the definition of a Hybrid cloud, which is a combination of public, private, and community cloud models and provides the benefits of multiple deployment models.
