Extend Scoping to Support Multiple Projects/Target Infrastructures

Overview

The scoping extensions outlined below are relevant to how SEs are monitored in GOCDB and support for hosting multiple projects within a single GOCDB instance.

Extensions

  • Sites, Services, and NGIs will each be able to define multiple 'scope' tags to associate each with different project/infrastructure scopes.
  • 'Site.scope' will be used to identify a site's Target Infrastructure (i.e. Grid/Project) rather than 'Site.Production_Status' value.
  • 'Service.scope'will be used to identify an SE's target infrastructure.
  • The scope value will become multi-selection, allowing a site and service to be associated with more than one project.
  • The PI '&scope' parameter will allow a comma-separated list of scope values rather than a single scope value.
  • The 'Site.Production_Status' value is EGI specific and should be used to represent site's overall quality (Production, Test etc) and *not* to identify the Target Infrastructure.
  • Once we move the GIIS URL from site to SE, it will be possible to define a GIIS Url per target infrastructure using duplicate SEs defined under different scopes.
  • The present certification statuses will remain.


Comment (Tiziana): shall we reconsider the semantics of the Target Infrastructure, and use it to define the target production infrastructure a site (or better: an end-point) belongs to? Examples of Target infrastructures could be: EGI, EUDAT, PRACE, TEST. This would mean replacement of what today is "Production" into "EGI".

  • Advantages. This would allow a single GOCDB site to host services that are part of different infrastructures.
  • Disadvantages. This requires a reconsideration of scoping. Scoping was defined to be a on off (either in EGI or out of it). By having N target infrastructures, not part of EGI would mean being part of another Target Infrastructure).

The impact of this change in production would be small as usage of scoping is still limited in GOCDB.

Comment (DM): Yes I agree with your comments, proposals updated to reflect these.

Definitions

Site.Production_Status

  • Values = Production|Test (PPS, SC obsolete)
  • EGI specific flag which is used as a mechanism to stop all of a site’s endpoints from being monitored.
  • The GOCDB ‘Site.Production_Status’ field is *currently* labelled in the portal as ‘Infrastructure.’ However, the Scope value should be used to identify the TargInfr as described above. We could consider deprecating the ‘Site.Production_Status’ field, but this field is currently used in EGI as a shortcut mechanism to indicate that all of a site’s services should be monitored or not.


Site.Scope

  • Values = EGI|Test|EUDAT|...
  • Lists the names of any Grids or Projects to which the Site belongs (an open enum list).
  • For GOCDB, ‘Local’ means the site is not part of EGI or any other named Project/Grid. This is equivalent to the ‘AdminDomain.OtherInfo.GRID=INFO’ value in the EGI_GLUE2 profile (p16) which means the Grid is unknown and is present for information purposes.


Site.Certification_Status

  • Values = Candidate(temporary, max of 2 months)|Uncertified|Certified(long-term state)|Suspended(temporary state, max of 4 months)|Closed(indefinite state)
  • EGI specific flag which is used to identify the site’s SA1 site certification status.
  • Only Certified sites services are monitored.


SE.Scope

  • Values = EGI|Test|EUDAT|...
  • Allows a Site to define a mix of services for different projects.
  • An extra business rule is necessary: An SE can only select a Scope from its parent Site Scope list.
  • In the EGI_GLUE2 profile there is no corresponding ‘Service.OtherInfo.GRID’ attribute defined for Service (section 2.8).


SE.Production

  • Values = True|False
  • Quality level/maturity level of the service - does the service deliver a production quality service (or not) to its Target Infrastructure/Project.
  • Maps to GLUE2 Service.QualityLevel = development|production|pre-production|testing (open enum)
