SanEd consulting

Company profile

SanEd consulting is an IT training company which initiated its services in 2005 primarily as Sun Microsystem's authorised training provider. Our training portfolio was Solaris and Java focused. Later on we upgraded our portfolio and included authorisations from Veritas / Symantec and Oracle after aquisition of Sun. 

As the global IT market is rapidly changing and developing we must have accepted its needs and trends. Thus, beginning of 2014 we decided to "refurbish" our services and included new, young and perspective partners and together prepared number of interesting trainings you can find in our catalogue.

We are looking forward to successful cooperation with you.

Prerequisites

Students should already be comfortable working in a Linux or Unix environment. Fundamentals such as the Linux filesystem, process management, and how to edit files will not be covered in class. An understanding of network concepts, and the TCP/IP protocol suite is helpful. These skills are taught in the GL120 "Linux Fundamentals" course.
