AWS: Cloud Servers

Describe the Web-Request-Response-Cycle

The messages sent by the client, usually a Web browser, are called requests and the messages sent by the server as an answer are called responses

Explain what a “server” is, as it relates to the WRRC

A server is a computer program or device that provides a service to another computer program and its user, also known as the client. In a data center, the physical computer that a server program runs on is also frequently referred to as a server. That machine might be a dedicated server or it might be used for other purposes.

What does it mean to “deploy” an application?

Application Deployment (also referred to as Software Deployment) is the process of installing, configuring, and enabling a specific application or set of applications, usually through an application manager (app manager) or software management system, to a specific URL on a server.
