The successful CERN openlab concept was formulated in 2001 and stayed basically unchanged throughout the last decade. CERN openlab has been organised into successive three-year phases.
In openlab I (2003–2005), the focus was on the development of an advanced prototype called opencluster.
Before the first phase of CERN openlab started in 2003, the collaboration carried out some intial work starting in 2001. The first CERN openlab annual report covers this period.
The framework of the second phase of openlab was similar to that of the first phase, with the aim of hosting a few major projects with a particular focus on Grid-related technologies and services. The projects were organized in four activities.
The fourth phase (2012-2014) addressed new topics crucial to the CERN scientific programme, such as cloud computing, business analytics, the next generation of hardware, and security for the myriads of networks devices.
The current phase V (2015-2017) is tackling ambitious challenges covering the most critical needs of IT infrastructures in domains such as data acquisition, computing platforms, data storage architectures, compute provisioning and management, networks and communication, and data analytics.
