About the Author

Gabriel Cánepa is a Linux Foundation certified system administrator (LFCS-1500-0576-0100) and web developer from Villa Mercedes, San Luis, Argentina. He works for a worldwide leading consumer product company and takes great pleasure in using FOSS tools to increase productivity in all areas of his daily work. When he's not typing commands or writing code or articles, he enjoys telling bedtime stories with his wife to his two little daughters and playing with them, which is a great pleasure in his life.

I would like to thank God for the many blessings and the growth opportunities in personal, family, and professional life that He has given throughout my life.

I would like to thank my mother, who always encouraged me to get as much education as possible and to excel in everything I do. I'd also like to thank my wife, Monica, and our two daughters, Camila and Francesca, for their support, understanding, and patience during the long hours of troubleshooting and writing this book.

Next, I'd like to thank Andrea de Ampalio and Diego Cordoba from Carrera Linux Argentina (www.carreralinux.com.ar), who helped me learn and love Linux in the best Linux training academy—their people and Linux skills are without match, and Subho Gupta, Manasi Pandire, Zeeyan Pinheiro and Vivek Pala from Packt Publishing for their remarkable talent and support while we worked together on this book.

Last but not least, I'd like to thank Andrew Beekhoff and the team at Cluster Labs (http://clusterlabs.org/) for putting together the best and most complete cluster resource information guide out there, which served as the main source of my research.
