HP Cloud Identity Service Overview

Based on Keystone, the OpenStack Identity Service, the HP Cloud Identity Service provides one-stop authentication for all HP Public Cloud offerings. Key terms include:

A digital representation of a person, system, or service who uses HP Public Cloud. The Identity Service validates that incoming requests are being made by the user who claims to be making the call. Users have a login and may be assigned tokens to access resources. Users can scope their authentication to a tenant which then limits where and how their tokens can be used to interact with services. Users are associated with tenants based on roles assigned to them with that tenant.
Data that belongs to, is owned by, and generally only known by a user that the user can present to prove they are who they are (since nobody else should know that data).
In the context of the Identity Service, the act of confirming the identity of a user or the truth of a claim. The Identity Service will confirm that incoming request are being made by the user who claims to be making the call by validating a set of claims that the user is making. These claims are initially in the form of a set of credentials (username & password, or user access keys). After initial confirmation, the Identity Service will issue the user a token which the user can then provide to demonstrate that their identity has been authenticated when making subsequent requests.
An arbitrary bit of text that is used to access resources. Each token has a scope which describes which resources are accessible with it. While the Identity Service supports token-based authentication in this release, the intention is for it to support additional protocols in the future.
A collection of HP service subscriptions and/or resources (Compute, Object Storage, etc).
A network-accessible address, usually described by URL, where a service may be accessed.
A personality that a user assumes when performing a specific set of operations. A role includes a set of rights and privileges. A user assuming that role inherits those rights and privileges. A token that is issued to a user includes the list of roles that user can assume. Services that are being called by that user determine how they interpret the set of roles a user has and which operations or resources each roles grants access to.

So go ahead and jump right in and and start using the service yourself, you should go to the Manage Console. If you have any questions, try our Forums where you can learn from our own internal experts as well as other users in the HP Public Cloud community.
