What does Sysadmin/DevOps do?
A system administrator, or sysadmin, is a person who is responsible for the upkeep, configuration, and reliable operation of computer systems; especially multi-user computers, such as servers. The system administrator seeks to ensure that
the uptime, performance, resources, and security of the computers they manage meet the needs of the users, without exceeding a set budget when doing so.Heading 2
To meet these needs, a system administrator may acquire, install, or upgrade computer components and software; provide routine automation; maintain security policies; troubleshoot; train or supervise staff; or offer technical support for
projects.*
