In the past few years Cloud Computing moved from buzzword to a disruptive computing model reshaping all IT landscape. The question today is not "why Cloud Computing?" but how don't get left behind if not in the Cloud. Cloud Computing is a paradigm shift that changed the way computer centers are managed, business operates, applications are written and users interact with devices, services and applications. During the last 2 years CERN also built its own Cloud infrastructure using leading open source tools that is helping scientists around the world to uncover the mysteries of the Universe. This lecture will introduce Cloud Computing concepts identifying and analyzing its characteristics, models, and applications. Also, you will learn how CERN built its Cloud infrastructure and which tools are been used to deploy and manage it.

About the speaker: Belmiro Moreira is an enthusiastic software engineer passionate about the challenges and complexities of architecting and deploying Cloud Infrastructures in very large-scale environments. He works at CERN and during the last two years his main role was to design, develop and build the CERN Cloud Infrastructure based on Openstack. Previously he worked in different virtualization projects to improve the large batch farm at CERN. Belmiro also holds a degree in Mathematics and has several articles about HPC, virtualization and cloud computing..
