Obrigado aos que deixaram comentários :)

Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

XCode is installed (via the App Store)
XCode command line tools are installed (xcode-select --install will prompt up a dialog)
Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

Typical Ruby on Rails AWS Server Setup

You should be able to start a fresh EC2 instance of Ubuntu and follow the instructions below to get a server with your preferred version of Ruby, nginx ready to delegate requests to Unicorn, and logrotate setup to keep your disk from filling up with log files. You will also have ruby-install for installing new rubies and chruby for switching between them. A .ruby-version file will be added to the home directory of the user that runs this script.

Install

Start an EC2 instance using the latest Ubuntu image (as of 2015-06-18 ami-5189a661 for EBS, 64-bit SSD)
Copy the config files below into /tmp using the file names specified in the title.
Edit /tmp/setup.sh and change the variables at the top to match your setup
Make /tmp/setup.sh executable: chmod +x /tmp/setup.sh

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

AWS Certification notes

Those are my personal notes on AWS Solution Architect certification preparation. Hope you find them usefull.

To pass AWS certification, you should have:

Sound knowledge about most of the AWS services ( EC2, VPC, RDS, Cloudfront, S3, Route53 etc,)
Hands on experience with AWS services.
