Effective and Comprehensive Management of IT Systems Using Open Source Management Solutions

Gain theoretical knowledge and practical skills in the application of open source solutions in the management of IT processes and IT infrastructure in a modern IT company

IT administrators, IT managers, IT project managers of small and medium-sized enterprises that have been thinking about implementing industry-leading open source systems in-house. IT people who want to broaden their knowledge of industry wide open source IT management, automation, monitoring, security software and have little/medium knowledge in this field.

IT solution architects, who have to plan the architecture and implementation of IT systems and IS.

• Assess which open source hypervisors can be used to create virtualisation solutions that meet test and high-availability requirements
• Set up a hypervisor, create a high availability cluster
• Assess the advantages and disadvantages of open source hypervisors and what is needed to implement an open source hypervisor in the enterprise. Create virtual machines and containers
• To create an effective virtual machine backup solution and plan
• Monitor your infrastructure and spot problems early, automate service recovery with open source solutions
• Implement an open source firewall and choose the most appropriate packages for traffic analysis and network security monitoring
• Create a private network without using a VPN solution
• Create open-source network disk arrays and run different types of services on them, which can be used in parallel by users and hypervisors
• Manage different types of scripts using an open source solution on multiple servers, see execution statuses from a single management console and create new execution scripts without ever logging into those servers
• Establish a centralised system for managing log files. Centrally store, analyse and process log files from different systems
• Implement a data visualisation platform to visualise different data sources, types, historical and online information
• To apply the Infrastructure as Code (IaC) approach to your infrastructure

Knowledge of Linux operating system at beginner level, practical skills in using SSH protocol, nano text editor.
