A one day sysadmin centric learning and sharing experience

The CentOS Dojo's are a one day event, organised around the world, that bring together people from the CentOS Communities to talk about systems administration, best practises in linux centric activities and emerging technologies of note. The emphasis is to find local speakers and tutors to come together and talk about things that they care about most, and to share stories from their experiences working with CentOS in various scenarios.

The Road Ahead: The CentOS project turned 10 years old in 2013. And even though it's been very productive, interesting and enjoyable - it's the future plans that are the most exciting. In this talk I will speak about some of these exciting goals and discuss the medium to long term efforts being planned and how this might impact the existing userbase, as well as how we create inbound paths for new users to get involved and derive the maximum value from what we do.

Cloud environment with CentOS, OpenNebula and KVM: Moving to a Cloud environment is the next logical step for any Virtualization environment. This step, that is sometimes daunting to undertake, is extremely simple with the powerful combination of CentOS, OpenNebula and KVM. In this talk we will discuss the benefits of moving to a Cloud environment using OpenNebula, and the appropriate workflows to manage the infrastructure while preserving the control and optimization that of Virtualization perspective. We will discuss in more details how to optimize your virtual machines. opennebula.pdf

Yum at Scale: Yum is a powerful package manager, being able to resolve dependencies, find the packages that own a given file and much more. However, it's a tool that runs on each machine, and that could, potentially, give different results on each node of your infrastructure at different points in time. In this talk we'll discuss the different resources in Yum and the open source community to guarantee perfect reproducibility of our software installations in large scale environments. yum-scale.pdf

C12G Labs headquearters are located at the Scientific Park of Madrid in Cantoblanco University Campus, which is approximately 20 km. north to the city center, so the most convenient way to stay within Madrid well connected via subway to enjoy the free time in the city and at the same time not spending too much time every day to attend the training is staying in the north of the city. The best areas in this sense are close to Chamartin (commuter train station). We recommend staying as close as possible to Chamartinstation, as getting to the campus using the commuter train is very fast (line C-4, only two stops to reach Cantoblanco Universidad, about 15 minutes + 10 minutes walk from Cantoblanco Universidad station to the our building).
