Linux System Administrator
Linux being adopted successfully by thousands of companies have a need for Linux Server administration but cannot justify the high cost of a full-time Linux System Administrator. The owners of small to medium enterprises have to pay heavy charges to the Server administrator for jobs like installing, upgrading any application/ package. Unavailability of such administrator when required is a common scenario.
To ensure maximum uptime, you have to proactively monitor your systems to detect any anomalies that might indicate an imminent problem. You also have to do routine upgrades, system tweaking and maintenance. Not every company has the luxury of IT staff they can dedicate to these tasks. And those that do would prefer to have their IT professionals doing more productive work like application development.
