VO Services
Goals
Setting up and operating a VO is a complex task that requires an important effort for ensuring a high quality of services. Many tools and services are available in EGI that rely on the VO information, and sometimes, procedures are neither easily available nor complete. The EGI VO Services subtask aims at supporting VOs in the whole process of start-up, management and operation, pointing out to tools, services, documentation and procedural guidelines to maximize the usage of the resources.
The VO services activities are summarized in four main points:
- VO Management Support: To set up a central documentation point with procedures, FAQ and a single contact point.
- Promote VO activities: To ease the access to tools and services to foster production quality by the users of a VO.
- VO Infrastructure Monitoring: To aid setting up tools for monitoring the resources under the point of view of the VO.
- VO Infrastructure Usage: To support the monitoring on the usage of the resources by the users from a VO or a VRC.
VO Management Support
Consultancy and Support
The GGUS VO Services Support Unit is one of the official communication channel at VO Managers diposal to receive support regarding procedures, services and tools they operate in their daily work. It has been established to provide a closer link with the technical services staff so that VO managers can:
- ask for consultancy services regarding tools and services
- ask for support while operating their VO
- ask for clarification of procedures or documentation improvements
- provide feedback regarding specific tools and/or services
The established workflow assumes that, while interacting with the VO managers, VO Services staff can involve different experts in the discussions, and bridge VO managers requests with the appropriate support units.
Through the interactions with the VO managers, tools, services and middleware requirements can emerge. It is the VO Services Support Unit responsibility summarize the discussion as a requirement, and insert in | EGI Request Tracker, the tool used in EGI to track the follow up of requirements.
Procedures, protocols and documentation
This page contains links to documents that will guide new emerging communities on selecting the services and tools they would need in the daily operation of the VO.

Services
In this frame, one of the needs that new communities have is the support of core services. Among those core services, we can identify:
- EGI central VO services: Those services already in place by the infrastructure, hold centrally and which will be automatically supported. Examples are the new VO monitoring database (evolution of CIC), accounting portals or information systems.
- EGI distributed VO core services: Those services set-up at the NGI level by previous agreements with users. Those services require dedicated hardware resources and continuous monitoring. Among those services we can list VOMS, WMS, LFC, PxServer, UI.
- VO local services: Services that require lower hardware resources, are less critical and can be operated at the VO-side from the very beginning. Among them we can cite thematic Wikis, monitoring visualization portals, etc.
Resources at point 1 are provided by default by EGI-InSPIRE. Resources at point 3 are provided by the user communities. Resources at point 2 are quite critical and cannot be easily provided by the VO community. Since there are some commitment from NGIs in this activities, we will start to claim for NGI effort in order to support such services.
In order to ask for access of a VO to a given catch all service, please open a ticket on the VO Services Support Unit in GGUS (also see Support section)
