Operating Linux in Virtual Machines (VMs)

Introduction:

Installing the Linux Operating System on Virtual Machines (VMs) is an effective and flexible approach in modern IT architecture. In this seminar, Linux architecture will be explained, and various installation methods, including graphical installation, will be demonstrated. Learners will become well-versed in basic and advanced Linux commands, assisting them in system administration and operations.

This course will also cover procedures for data backup and restoration, enhancing system availability and promoting business continuity. Participants will learn advanced shell scripting techniques for task automation to improve system efficiency.

Students will explore the possibilities and limitations of VMs in a Linux environment and learn best practices for installing Linux systems in such environments. The course highlights the utilization of VMs for testing, deployment in controlled environments, and using the build and deployment capabilities of Linux.
