Common Scenario

Each developer has its own favorite/predefined stack of technologies.

● OSX/Linux/Windows

● Distros/Versions

● Apache/Nginx

● WAMP/XAMPP/MAMP

● PHP 5.??/Rails/Node.js

● MySQL/MariaDB/SQLite

● Modules/Extensions

● Libraries & Dependencies

● PEAR/PECL/Composer

● Memcache/Varnish

"If you've ever maintained a large application, one of the hardest parts is onboarding new resources."

"Running everything on a home machine and remembering to turn it all off in the end of the day is unfeasible."

"Develop on OSX and deploy on Ubuntu and you’ll be surprised with ugly encoding issues."

● version differences

● platform-related issues

● config and tweaking

● time consuming op.

● home station messed up

BUT IT WORKS ON MY

MACHINE...

It's important to build and maintain a software using the same requirements on all environments it will be deployed.

Forcing developers to use the same OS is going to lead to problems, reduced productivity and promoting nerd-fighting.

ChangeSuggestion

Create and configure lightweight, reproducible and portable development environments.

Vagrant up!

Boxes

Virtualization

Vagrantfile

$ vagrant up

$ vagrant init

$ vagrant suspend

Provisioning

You can easily automate repetitive tasks, quickly deploy critical applications, and proactively manage changes.

Puppet

Declarative Language

Modular

Reusable

Puppet

package { “ruby”:ensure => latest
