Virtualization technologies

 Not united by networks

When working with a network, it is very difficult to avoid contact with the server infrastructure. That is why you must have at least basic skills in this area. In most organizations, server specialists are assigned to a separate group. At the same time, network specialists are very often forced to contact them and must communicate in “the same language”. Below we describe a few more essential skills for a network engineer:

Virtualization technologies.It's hard to imagine a company that doesn't use virtualization tools. Moreover, not only servers, but also networks go into virtualization. In many organizations, firewalls, routers, and intrusion prevention systems are also represented as virtual machines. Basic VMware ESXi and Microsoft Hyper-V skills are a must. You need to understand what a virtual switch or virtual adapter is. Again, I recommend courses from CBT Nuggets . You can also look at Udemy.

Basics of working with Linux.I think this point is also obvious to everyone. A huge number of routers and firewalls are based on Linux. Proxy, Anti-Spam, IPS, DLP systems ... all of this in most cases is slightly modified Linux. Therefore, it is very important to be able to navigate the file system, execute the simplest troubleshooting commands (ip route, tcpdump, traceroute) and edit configuration files using the built-in text editors (vi). A basic CentOS course is a good place to start.
