Eloqua has many apps that can be installed to extend the functionality of the application. These apps can be developed by our internal Eloqua labs team, but they can also be created by any third party (including by Eloqua partners, and by our clients). The Eloqua AppCloud, which can be found at Appcloud.eloqua.com is a marketplace of apps, covering a wide range of functionality, such as events, data augmentation or social.
Although Apps are deeply integrated within Eloqua, they are outside of the code of the Eloqua application. As such, they need to be hosted and managed somewhere. Apps that are created by Eloqua labs are housed and managed at cloudconnectors.eloqua.com. Currently, cloudconnectors.eloqua.com houses Cloud Connectors and Cloud Feeders. It is free, but does require a separate login.
