GOALS for this course



Lecture Notes of G679 (University of Cantabria)

This couse aims to teach students the required skills for performing tasks of a junior system administrator in computer environments. Students will learn advanced procedures about the design and the management of computer systems for data center environments that will enable them through the integration of the different components of the system, to implement advanced services that will be used in the management of computational resources, distributed storage and networking, in both the Intranet and the Internet environments. Also, we will place special emphasis on the main security mechanisms for these service. Additionally, we will take a look at some of the more relevant “open-source” tools in monitoring and remote configuration.
