Requirements
Participants should possess familiarity with basic system administration tasks via the Linux command line. Certain topics assume prior programming or scripting experience. When booking, please specify the programming languages you are comfortable with. If you have no preferred languages, the course will focus primarily on using Redis commands via redis-cli.
