Linux & Unix

Stable, low hardware requirements, feature rich, rapid development, and free – these are just some of the best aspects of a Linux system.  ESI has long been a supporter of Linux and the FOSS movement.  We began using GNU/Linux systems in 1995, and began deploying them in 1997 if it was feasible and could meet our client’s needs.  With a few exceptions in very specialized industries, our Linux deployments are almost always back end solutions – servers for web, e-mail, databases, and large storage arrays.  While the majority of tools are in place to deploy a Linux system to the Desktop, we’ve found that (at least as of right now) the cost in training and re-educating staff mitigates any short-term savings gained by switching from Windows or MacOS to Linux.  That said, we’ve made plenty of clients happy that were told they needed a new Windows server, when we backup their old server, slap Linux on it, and let them extend the life of their existing hardware for another couple of years.  It doesn’t matter to us which “flavor” of Linux you’re running – RedHat, Ubuntu, CentOS, Suse, or any of the others; we’ll be here ready to help with them.

We have worked with most major Unix and Unix-like systems over the years, including System V, Solaris, BSD, AIX, and HP-UX.  While most of these systems can trace their roots all the way back to the original AT&T/Bell Labs UNIX of 1969, they all developed their own little differences and idiosyncrasies over the years.  With ESI’s focus on Small to Medium Enterprises (SME), we’ve found Solaris and BSD (especially it’s descendants – FreeBSD, NetBSD, and OpenBSD) to be the most prevalent Unix systems in this market.  Our staff is competent in supporting and managing these systems, and will even work with your vendor if you’re running a proprietary Unix solution.
