DEPLOYMENT

?

DEPLOYMENT is all of the activities that make a

software system available for useSoftware deployment

copy/clone code base to serverrun composer commandsmigrate your databasereload the web servernotify about the deploymentand so on...

DEPLOYMENT GOALS

One-click / command deployment

Source: devopsreactions.tumblr.com

Anytime & Anywhere

Anyone (with permission) can deploy

Nominal/No downtime (ZDD - zero downtime deployment)

Reliable Rollbacks

Pushed code to production, recalled there was a critical bugSource: devopsreactions.tumblr.com

Reusable and should be reproducible (repeatable)

Scalable

BENEFITS OF AUTOMATED DEPLOYMENT

Deployments become much less error-prone

compared to this...

This simulates a manual deployment

Anyone in the team with permission can deploy software

Engineers will spend most of their time developing software

and not have to face this kind of situation...

Problematic deployment is over

Deploying to somewhere new is not a headache

You can release features more frequently as its easy,automated and reproducible
