Let’s make it work for you
Overview
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 and Unix 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 and Unix technology, by discussing a hybrid of topics that span user and administrator tasks and activities.
Target Audience:
The course is aimed at existing IT professionals with little or no UNIX/Linux experience, who require a quick start in Linux and Unix environments, enabling them to control a Linux and Unix based systems swiftly, efficiently and with full understanding of the underlying principles.
Typical delegates would be current users of Windows, Mac OS, or other professionals (such as software developers, system or network administrators) who need to gain a solid understanding of the environment of LInux and Unix and facilities provided by them.
Prerequisites
