Você já parou pra pensar que sua stack de desenvolvimento (Apache, PHP, MySQL, etc) consome recursos de sua máquina do trabalho ou pessoal em momentos que você não está desenvolvendo? E quanto ao setup de ambiente e as muitas configurações que precisamos fazer a cada projeto novo que chega ou quando algum membro novo entra no time? Logo depois, como garantir que todos do time estão utilizando exatamente as mesmas versões para garantir máxima compatibilidade entre os diversos ambientes (local, staging, produção, etc)? Venha conhecer como a combinação entre duas tecnologias irá automatizar bastante processo manual economizando tempo e recursos e garantindo maior compatibilidade.

4. Common
Scenario

5. 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

6. "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

7. BUT IT
WORKS
ON MY
MACHINE...

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

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

10. Change
Suggestion

11. Create and
configure
lightweight,
reproducible
and portable
development
environments.
Vagrant up!

12. Boxes
Virtualization
Vagrantfile

13. $ vagrant up
$ vagrant init
$ vagrant suspend

14. Provisioning

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

16. Declarative Language
Modular
Reusable
