Description
Collaborative services and tools are essential for any (HEP) experiment.
They help to integrate global virtual communities by allowing to share
and exchange relevant information among members by way of web-based
services.
Typical examples are public and internal web pages, wikis, mailing list
services, issue tracking system, services for meeting organization and
document and authorship management as well as build services and code
repositories.
In order to achieve stable and reliable services, the Belle II
collaboration decided after considering different options to migrate the
current set of services into the existing IT infrastructure at DESY.
The DESY IT infrastructure is built to be reliable and highly available
and has been providing sustainable services for many scientific groups
such as CFEL and EXFEL as well as for HEP. It includes fail-over
mechanisms, back-up and archiving options for all services.
As for all computer centers, security is a major issue at DESY which is
thoroughly considered for all services.
In order to make optimal use of the existing services and support
structures at DESY, implementation switches are necessary for some services.
Hence not all services can simply be copied but will have to be adapted
or even restructured.
In preparation for the final migration small groups of experts went through
the details of all services to identify problems and to develop
alternative solutions.
In the future the Belle II collaboration will be visible in web under
the domain 'belle2.org' which is owned and hosted by DESY.
It will also be necessary to equip all Belle II members with credentials
to access DESY services. For this purpose a certificate and VO membership
based portal is set up which allows for authentication and authorization
of users.
After the approval by the Belle II bodies the migration process
started in spring. It must be finished before the KEK summer shutdown
in July.
In the contribution to CHEP2016, at a time when the migration process
must have finished, we will describe various aspects migration process
and the services. Furthermore we plan to share experiences, reveal
details, and give useful hints for similar approaches.
