2. FIWARE
 FIWARE is an innovative, open cloud-based infrastructure for cost-effective
creation and delivery of Future Internet applications and services, at a scale
not seen before.
 These APIs are public and royalty-free, driven by the development of an open
source reference implementation which accelerates the availability of
commercial products and services based on FIWARE technologies.

3. FIWARE Generic Enablers
 Generic Enablers (GE) offer a number of general-purpose functions, offered
through well-defined APIs, easing development of smart applications in
multiple sectors. They will set the foundations of the architecture associated
to your application.
 Specifications of FIWARE GE APIs are public and royalty-free. You can
search for the open source reference implementation, as well as alternative
implementations, of each FIWARE GE in the FIWARE Reference
Architecture.

29. Private Regions Support
 Goal
• Support to private regions that wants to offer part of their Cloud resources to
FIWARE Lab users

30. The scenario
• FL user represent a user with a registered account in FIWARE Lab
• In FIWARE Lab environment, FL OS Services represent the services of all the Federated nodes
• Private Cloud is a Commercial Cloud Provider that wants to offer some of its resources (part of Local OS
Services) to be available in FIWARE Lab as a new node.
• Private Cloud has their own users registered in its local Keystone (Ext User is one of them) and using Cloud
resources deployed in Local OS Services

31. Requirements
• Ext User can continue using his deployed resources in Local OS Services using Horizon
• FL User (if he has the correct rights) can deploy resources in Private Cloud Local OS Services using Cloud
Portal
• In Cloud Portal, Private Cloud node appears as a new node. It is accessible for FIWARE Lab users with quotas
in that node (community users assigned to that node)
• Private Cloud infrastructure owners can assign quotas of Local OS Services to FIWARE Lab users (to their
cloud projects)
• FL User can continue using FL OS Services as before.
• If a Ext User wants to use FIWARE Lab nodes resources, he has to create an account in FIWARE Lab.

32. Solution – FL User using FIWARE Lab resources
Everything works as always
1. Cloud Portal authenticates the user in Keyrock
2. Cloud Portal sends a request to an OS Service
3. OS Service validates the token with Keyrock

33. Solution – Ext User using Local resources

34. Solution – FL User using Private Cloud resources
1. Cloud Portal authenticates the user in Keyrock
2. Cloud Portal sends a request to a Private Cloud OS Service
3. Private Cloud OS Service tries to validate the token in Keystone
4. As the validation doesn’t success (the token is not stored in Keystone), Keystone validates it with Keyrock
acting as a gateway and sending the response to Private Cloud OS Service
*. If the validation success, Keystone stores the token locally (in cache), so the next times the step 4 is
not required.

37. Conclusions
 Evolution and integration between OpenStack and a IDM.
 Evolution in Open Source (development by UPM in the proyect).
 Identity solution widely used among all the startups ( Most used GE ).
 Goal to have it integrated in different susteniable ecosystems:
• Full integration with OpenStack.
