LPAT302 Advanced Administration of Virtualised and High Availability Systems - A Level 3 Advanced Specialisation

Duration: 5 Days

Background and Intended Audience

This course is based to a large extent on the syllabus of the LPIC 304 exam. It is focused on administration of virtualised and high availability systems. This is a relatively new certification syllabus, inspired, no doubt by the positively stellar developments in cloud computing, software defined networking and virtualisation technologies. This specialisation has to be learned experientially, following in the footsteps of those who have gone before, experimenting and trying out various approaches and designs. Cloud computing and the Internet of Things can be thought of as "The Wild West" of Internet Technology developments. Configuring and managing large cloud based operations is an area where those with the required skills and inventiveness can thrive. For those that are good (or about to become good once they have mastered the various technologies) the rewards are very great.


Attendees are assumed to have considerable Linux system admin knowledge equivalent to that required for LPIC Level2 such as might have been acquired by completing LPAT201 and LPAT202 training or equivalent and several months practical experience involving Linux system administration. Attendees are also expected to have experience of admin tasks such as setting up user accounts, configuring tailored linux builds and setting up a wide variety of applications. Some knowledge of hypervisors and virtualisation will be helpful, though this is not essential as the course will cover this topic.l For those contemplating taking this course as a distance learning course the number of hours of work involved is from 150 to 250 hours, and, possibly, even longer, with much of the time being spent setting up and configuring virtulised network systems, clusters of computers and trying out the various scenarios and challenges provided.
