Having had a brief introduction to GNU/Linux systems, the following step is to integrate them in the work environment as production systems. According to the current system in use, we can consider either a full migration to GNU/Linux systems or a coexistence through compatible services.
Migration to the GNU/Linux environment may be done progressively by replacing services partially or by substituting everything in the old system by GNU/Linux equivalents.
In current distributed environments, the most relevant concern is the client/server environments. Any task in the global system is managed by one or more dedicated servers, with the applications or users directly accessing the offered services.
Regarding the work environment, whether in the simplest case of the individual user or the more complex case of a business environment, every environment will require a set of services that we will need to select, later adjusting client and server machines so that they can access them or provide their use.
The services may encompass different aspects and there tend to be various types for sharing resources or information. File servers, print servers, web servers, name servers, e-mail servers etc., are common.
The administrator will normally select a set of services that need to be present in the work environment according to the needs of the end users and/or the organisation; and must configure the right support for the infrastructure, in the form of servers that support the expected workload.
