GETTING STARTED IN A LINUX CAREER
March 27, 2019 by Oliver Bailey
As I mentioned in my previous article, Linux is used in a number of ways across IT. For the IT pro, that translates to a wide variety of career opportunities. Within computer networking and IT infrastructure alone, this remarkable operating system has seen exciting growth. Linux skills can be applied to any number of IT disciplines, so whether you are looking to grow in your current specialty or branch into something new, there are many rewarding opportunities with Linux. Linux in IT Infrastructure – Then and Now Traditional systems operations and administration jobs still need skilled IT pros. And, as in the past, this is a great place to launch a career in Linux. But given that Linux now runs on such a wide variety of platforms, you could work on small or large systems, on mainframes or embedded Linux systems. The point is, the same Linux is used to do many different things. With the expansion of virtualized and cloud computing centers, IT infrastructure has been forever changed. And a third major new infrastructure category is responsible for that change: cybersecurity. This is creating systems administration, operations, support and engineering positions that previously did not exist. For someone just starting a Linux career, understanding machine virtualization and containers provides an exciting new pathway to a systems administration role or to a more technical role in systems, communications or specialized support of the internet of things (IoT) or embedded Linux. Creating and Administering Virtual Machines and Containers Running an application in a container allows for monitored restricted access to resources and keeps the contained application private from the prying eyes of hackers. IT pros may use Linux to configure containers for one or more of the following applications: • Processing credit cards • Managing health care
• Protecting a factory shop floor • Managing a utility or power grid • Routing mass transit • Securing a public building
