EGEE service baseline list

  • Objective:

    • To limit the lifetime of middleware service versions

      • To manage the amount of support needed

      • To reduce the security risks


Which versions to support
Which versions to support?

  • Rules for selecting which versions to support must be as simple as possible:

    • all versions released during the past x months

      • Where x depends on a subjective analysis of the frequency of updates to the service

        OR

    • all versions since the last “high priority” update for the service

      whichever is the more recent

  • The list of supported client versions can be found here:https://twiki.cern.ch/twiki/bin/view/EGEE/SupportedClientVersions

  • The list of supported service versions can be found here:https://twiki.cern.ch/twiki/bin/view/EGEE/SupportedServiceVersions


What s actually in production
What’s actually in production?

  • We need a way to identify the middleware service versions which are in production.

  • Currently using the various service interface version numbers that are published in the information system

    • This is too coarse a view

    • Stephen Burke has developed an info provider to publish the version of the metapackage (Patch 3214). Certified but not in production yet.


Monitoring
Monitoring

  • Plan to have a machine readable version of the list of supported service versions

    • This will allow automation of the flagging of “out of date” services in the production infrastructure

  • In the meantime, will have to do this manually

  • Sites with outdated versions will be warned and eventually suspended

    • Unless they give a good reason why they can’t upgrade – then they’re on their own
