Abstract
Windows Terminal Servers provide application gateways for various parts of the CERN accelerator complex, used by hundreds of CERN users every day. The combination of new tools such as Puppet, HAProxy and Microsoft System Center suite enable automation of provisioning workflows to provide a terminal server infrastructure that can scale up and down in an automated manner. The orchestration does not only reduce the time and effort necessary to deploy new instances, but also facilitates operations such as patching, analysis and recreation of compromised nodes as well as catering for workload peaks.
Highlights
The CERN Windows Terminal Servers service has two major functions: provide access to CERN network from outside; and, control the access to critical or key parts of the accelerator complex
Extensibility Because the Service Management Automation (SMA) is based on PowerShell scripts and workflows, it can be integrated into existing systems like System Center Operation Manager with PowerShell integration modules and automation connections
Managing continuously growing systems with the same manpower requires the solution of arising issues in a fast and automated way
