Ubuntu Enterprise Cloud provides a minimal web interface to manage user credentials, manage images, administer user accounts, etc.
In our sample setup, the web interface is accessible at:

You have already finished setting up the password for the admin user of the web interface while working on Desktop1 in the chapter on “Installation & Configuration”.
A user trying to access the interface for the first time, would need to sign up and would be able to use the interface after the account is approved by the administrator. The approval of the account by the administrator results in an emal to the user.

Cloud
Cloud Computing is a computing model, where resources such as computing power, storage, network and software are abstracted and provided as services on the Internet in a remotely accessible fashion. Billing models for these services are generally similar to the ones adopted for public utilities. On-demand availability, ease of provisioning, dynamic and virtually infinite scalability are some of the key attributes of Cloud Computing.
An infrastructure setup using the cloud computing model is generally referred to as ‘Cloud’. The following are the broad categories of services available on the ‘Cloud’:
- Infrastructure As A Services (IAAS)
- Platform As A Service (PAAS)
- Software As A Service (SAAS)
This ‘Cloud’ is generally available as service to anyone on the Internet. However, a variant called ‘Private Cloud’ is increasingly becoming popular for private infrastructure that has some of the attributes of the ‘Cloud’ as mentioned above.
Amazon Web Services is one of the major players providing IAAS. They have 2 popular services – Elastic Compute Cloud(EC2) and Simple Storage Service(S3). These services are available through web services interfaces. The client tools can use EC2 and S3 APIs to communicate with these services. The popularity of these APIs have encouraged other Cloud products to provide support for them as well.
