Just started using “the cloud”
My second dev job
Yay I'm not alone!

I was still "the server person"

Scaling a team
We needed to scale up (and skill up) our team
My second dev job
Scaling a team
Version control is NOT renaming files
Version control EVERYTHING
Trial & Error is ok!
Scaling a team
Stop Editing In Production!
No more edit & uploading!
Everything goes into
version control!
Disable FTP Access*!
# echo troy >> /etc/ftpuser
# echo andy >> /etc/ftpuser
# echo joe >> /etc/ftpuser
Better yet, disable FTP completely*
*If you can
Scaling a team
Development environments
MAMP, LAMP, WAMP, WAT?
Mac/Linux/Windows Apache MySQL PHP
These are all great tools
Do you deploy to MAMP/WAMP?
Why develop on a different configuration?
Catch those environment bugs earlier
Remove the phrase “…It works on my machine…”
From your team
Stop using WAMP/MAMP and start using Vagrant!
Vagrant allows you to:• Create a server• Configure a server• Delete a server
…over and over and over..
Not sure how to create a Vagrant box?
Guided path to create your own Vagrant
Supports common Distributions
Customize users, firewall rules, cron jobs
Add databases, virtual hosts
Supports Ruby, PHP, Python, NodeJS, HHVM
Beanstalkd & RabbitMQ
Elastic Search & Apache Solr

Great for learning HOW to build boxes
Especially useful if you’d like to learn Puppet
Other Provisioners
Shell
Chef - use existing Cookbooks
Docker - used if your app is in Docker
SaltStack

Scaling a team
Test your code!
Testing was the hardest part for us.
The payoffs in catching regression bugs and confidence in our deployments was
well worth it
Is your code testable?
If unit testing is hard, your code may not have been written to be testable.

Continuous Integration Continuous Delivery
Continuous Integration
Frequently integrate code changes into the existing code repository
Merging branches to master/production
Automated build tests to ensure issues found quickly
Does not have to be deployed
Continuous Delivery
Produce valuable changes in code in short cycles to be released at any time.
AKA: Continuous Deployment
Automated build tests to ensure issues found quickly
Deployment happens on successful build
Which is right for you?
Your goal should be Continuous Integration (at least!)
Strive for Continuous Delivery if it makes sense
Applications with a live event component may not be suited for Continuous Delivery
There are a lot of CI solutions out there

What is your process?
Create your workflow
Optimize your time in the console
Work smarter not harder
Stop typing the same commands
git status
git pull origin master
git branch —set-upstream-to=origin/master
vagrant global-status | grep running
redis-server /usr/local/etc/redis.conf
php -S localhost:8000
ssh [email protected] -t screen -dR irc
gs
gpm
gsu
vgr
startredis
startphp
irc
Make use of aliases
alias gs=“git status”
alias gpm=“git pull origin master”
alias gsu=“git branch —set-upstream-to=origin/master”
alias vgr=“vagrant global-status | grep running”
alias startredis=“redis-server /usr/local/etc/redis.conf”
alias startphp=“php -S localhost:8000”
alias irc=“ssh [email protected] -t screen -dR irc"
Use Screen for long running processes
https://www.mattcutts.com/blog/a-quick-tutorial-on-screen/
Think of screen as a detachable window that contains your console

Bash isn’t the only shell!
http://ohmyz.sh
Uses zsh
180+ Plugins
700+ Contributors
140+ Themes
myZsh
Why do I use myzsh over oh-my-zsh?
Why do I use myzsh over oh-my-zsh?
Customize your shell
• Local IPs• Date
Green Text because this is
the local machine
• User• Hostname• Current Path• Current time
Customize your shell
• User• Hostname• Current Path• Current time
• Local IPs• Date
Red Text because this is
a remote machine
Customize your shell
Tab completion on steroids+ Git branch info because we are in a repo
Tab Completion Demo
.zshrc
Automate Common Tasks
Alias long commands
Shell script sequential commands
Use cron to run your scripts at specific times
Create installers for your settings
Version Control Configs
Do NOT version control your SSH keys!
Do NOT version control your API keys!
Recap
Version Control everything you can
Create a process that works for your team
Practice how you play
Test everything you can
Automate everything you can
