Many institutions have been adding Linux machines to their existing infrastructure: perhaps to give developers a platform of their choice, to provide an alternative to a network server, or perhaps to introduce an additional piece to the security jigsaw. Linux systems are also being introduced as part of virtualisation environments (for example, with the use of VMware or XEN, KVM or VPC), allowing access to a mixture of operating systems from a single workstation or server. This course will give the delegates the skill set preparing them for a successful future with Linux technology, by discussing a hybrid of topics that span user and administrator tasks and activities.
