What is the problem anyway?

Setting up a development environment is not a fun way to spend an afternoon. Options:

• Using a remote server
• Installing everything locally
• Creating a virtual machine

Let's take a look at each of these...

Using a remote server

Pros:

• It's separate from your machine
• No divergence of environments
• You can rebuild your own machine at will

Cons:

• You have to push code to it
• You probably have to share it with others
• It's just inefficient at best
• What if you're out of the office?

Installing everything locally

Pros:

• You have complete control over it
• Nobody else is breaking using it

Cons:

• It's time-consuming
• It's not easily repeatable
• Barrier to rebuilding your machine
• No standards among teammates

Creating a virtual machine

Pros:

• It keeps your own machine cleaner
• VM's can be snapshotted
• VM's are portable (sort of)

Cons:

• Initial installation is time-consuming
• Virtual machine images are big
• There's still configuration when copying them

Enter Vagrant!

Pros:

• Can be run entirely on your machine
• Defines all configuration externally
• Consistent, repeatable, and reliable
• Can standardize environments for your team
• Keeps your own machine cleaner
• You can rebuild your own machine at will

Cons:

• Expectation of increased productivity?

What is Vagrant?

Vagrant is a tool that allows developers to...

"Create and configure lightweight, reproducible, and portable development environments."

• Available for Linux, Mac, and Windows
• Also available as a Ruby Gem
• Uses Oracle's VirtualBox
• Uses Puppet or Chef for provisioning

Examples!

What is Puppet?

"Puppet is IT automation software that helps system administrators manage infrastructure throughout its lifecycle, from provisioning and configuration to patch management and compliance."

• Define all your configuration in text files
• Apply the configuration to machines
• Modify the configuration at will
• Ensure that all machines are up-to-date
• Simple yet powerful technology

More examples!

Simulating production architecture?

A single VM is all well and good, but we need to simulate production. No problem!

• Create as many types of VM's as you like
• Spin up one of each or entire clusters
• The only limit is your hardware

Even more examples!

Integration with Amazon EC2

• Yes. Several possible workflows. Here's mine...
• 1. Define all configuration in Puppet
• 2. Test the configuration with Vagrant
• 3. Create EC2 instances
• 4. Run a setup script on each instance
• 5. Run headless Puppet on each instance

Tools are evolving rapidly, so this approach is probably already kludgy... but it works.

One more example!
