About the Authors

Andrea Dalle Vacche is a highly skilled IT professional with over 14 years of experience in the IT industry and banking. He graduated from Università degli Studi di Ferrara with an information technology certification. This laid the technology foundation that Andrea has built on ever since. Andrea has acquired various industry-respected accreditations, which include Cisco, Oracle, RHCE, ITIL, and of course, Zabbix. Throughout his career, he has worked in many large-scale environments, often in roles that have been very complex, on a consultant basis. This has further enhanced his growing skill set, adding to his practical knowledge base and increasing his appetite for theoretical technical studying.
Andrea's love for Zabbix came from his time spent in the Oracle world as a database administrator/developer. His time was spent mainly on reducing ownership costs, specializing in monitoring and automation. This is where he came across Zabbix and the flexibility it offered, both technically and administratively. With this as a launch pad, Andrea was inspired to develop Orabbix, the first open source software to monitor Oracle's complete integration with Zabbix. He has published a number of articles on Zabbix-related software, such as DBforBIX. His projects are publicly available at http://www.smartmarmot.com. Currently, Andrea is working as a senior architect for a leading global investment bank in a very diverse and challenging environment. He deals with many aspects of the Unix/Linux platforms as well as many types of third-party software, which are strategically aligned to the bank's technical roadmap. In addition to this title, Andrea Dalle Vacche is a coauthor of Mastering Zabbix, Packt Publishing.
Stefano Kewan Lee is an IT consultant with more than 12 years of experience in system integration, security, and administration. He is a certified Zabbix specialist in large environments holds a Linux administration certification from the LPI and a GIAC GCFW certification from SANS Institute. When he's not busy breaking websites, he lives in the countryside with his two cats and two dogs and practices martial arts. In addition to this title, Stefano Kewan Lee is a coauthor of Mastering Zabbix, Packt Publishing.
