Software installation, updates and maintenance
SysAdmin is responsible for defining policies and procedures to keep up with the installation and updating of the software. If errors occur with new updates or dependencies between new versions of the system, SysAdmin should be able to recognize and resolve these problems.
Redundancies, rollovers and recovery plans
System administrators should have active and updated plans for redundancies, rollovers and incident recovery. Effective monitoring, alarms and cross-functional communications should allow the system administrator to quickly identify errors and correct IT incidents.
Security
Security should be at the center of all the work a system administrator works on. Regardless of whether it affects your rights or how the team manages the documentation, system administrators must perform all actions safely. When setting up networks, policies and servers, SysAdmin knows how to do it technically flawlessly and securely.
Retain documentation and update runbooks
System administrators often have the task of keeping documentation and keeping runbooks up to date. In an CI / CD world, this can be a daunting task. System administrators need to know how automation can help them keep runbooks and documentation accurate and up to date without slowing the development lifecycle.
Detection, response and resolution of incidents
System administrators cannot simply join their IT and security environment. You have to build it thinking about visibility and speed. How can you set up a system that allows you to quickly detect, respond and resolve incidents in case of problems? What kind of monitoring and warning should be available? What is the communication strategy if you find an error? System administrators must answer all these questions to get the most out of their incident management practices.
