John Cleary

Lead Developer at IntelliCentrics UK

x years PHP (where x > 10)

CONFIGURED FOR DEPLOYMENT OUT OF THE BOX

PLAYS NICE WITH MULTIPLE SERVERS

UNDERSTANDS THAT DIFFERENT BOXES DO DIFFERENT THINGS (ROLES)

NOT JUST FOR DEPLOYMENT

STAGES, ROLES & TASKS

Stages are the environments (can be multiple servers)

Roles are the jobs servers have, i.e. “I’m a database” == :db

Tasks are actions that we can perform on a server, e.g. deploy or restart apache (see cap -T)
