DevOps?

A „natural“ roles conflict

Architects

Managers

The shift

Application

A complex application ismuch morethan just the sum of itscomponents. Its code,configuration, environments,infrastructure, security,nodes, databases, services

Fences hurt

infrastructure=code

Pick one

You pick the general strategy:- hosted Chef- own Chef server- Chef solo (mini)

hit the road

You decide where to keepconfiguration JSON/Ruby DSL„code“:- file based under own version control- in Chefs configuration database

play god

You decide whichenvironments you need / haveand configure / manage themseparately:dev, test, QA, team, preprod,integration, load test, prod,whatnot

play cook

You pick necessarycookbooks and their includedrecipes from:- OpsCode repository- community sources- GitHub- own ones

play theatre

You define roles andcorresponding run-lists (includingtransitive dependencies) andassign them to machines:- web-server- app-server- queue server- whatnot-server

Further abstractions for that are: - providers / resources - templates - data bags - files - attributesYou can use all of them to tweakyour deployment / config

Knife is yourweapon

ohai is your oracle

rastru cture=codeinf

ip ts, sc r r o ld y o u a n dru n a rn n le the ract st ab

And isnt excessive abstraction what really makes agood Enteprise Java solution? ;)

let it run

again and again

and Java?

You use same stuff, e.g.:- your environments- application, JDK, tomcat, DB cookbooks- adjust your attributes- configure infrastructure same way (load-balancer etc.)
