The choice and the eventual deployment of an operating system is only the first step an organization takes in configuring and building a network infrastructure. Except in the most rudimentary networks, IT professionals need to take into account the types of network management tools that they intend to utilize to manage, monitor, maintain, analyze, and secure the network. IT professionals must also provide infrastructure services to the organization, such as directory and certificate services. Red Hat and other commercialized open source distributions tout the notion that Linux frees users from vendor lock-in, and they paint a picture of users easily moving from one Linux distribution to another. However, the reality of moving from one distribution to another is not without concerns, as Linux distributions differ in package managers, supported packages, and installed libraries, resulting in work to change distributions. In addition, some commercialized open source distributions, such as Red Hat, provide additional software that is supported only on their platforms. If organizations use this software, as many do, the problem of changing distros is compounded.
