Connections provide access to data in cloud and on-premise applications, platforms, databases, and flat files. They specify the location of sources, lookup objects, and targets that are included in a task.
You use connectors to create connections. You can create a connection for any connector that is installed in Informatica Intelligent Cloud Services. Many connectors are pre-installed. However, you can also use a connector that is not pre-installed by installing an add-on connector created by Informatica or an Informatica partner.
