GOALS for this course



Lecture Notes of G679 (University of Cantabria)

The main objective of this course is to acquire the required skills for performing tasks of a junior system administrator in computer environments like modern “Data Centers”. We will learn advanced procedures about the design and the administration of computer systems for data center environments. This will allow us, 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. 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.
