• Version Control
• Time and Money
• Actually Working

Part 1:
Hosting
Friday, June 19, 2009

Open Source Hosting
• LAMP (Linux/Apache/MySQL/PHP) is the
most common
• Webservers: Lighttpd, Nginx, Mongrel
• Databases: PostgreSQL, Firebird, Drizzle,
CouchDB
• Languages: Ruby/Rails, Python, Perl, etc.
Friday, June 19, 2009

4 Types of Hosting
• Shared Hosting
• Virtual Private Server
• Dedicated Server
• Cloud Hosting
Friday, June 19, 2009

Shared Hosting
• Cheap, ready-to-go, no technical expertise
needed
• Often over sold, not much control, not
very scalable
• Distributed vs. Traditional
Friday, June 19, 2009

Virtual Private Servers
• A chunk of a server is virtualized and made
available to you.
• More power/control than shared hosting
without the cost of dedicated server.
• Managed and Unmanaged.
• Many options: verify that resource
allocation, options meets your needs.
Friday, June 19, 2009

Dedicated Server
• You have your own server. More control,
more power.
• Managed and unmanaged.
• Most expensive option.
Friday, June 19, 2009

Cloud Hosting
• Dynamically scalable and virtualized
hosting.
• Pay for what you use. Scale up/down very
quickly.
• Technologies vary.
• Google App Engine (java/python), Amazon
EC2, RackspaceCloud (Mosso).
Friday, June 19, 2009

Local Hosting
• Your laptop/desktop can act as a web host
• Great for developing, designing and testing
• Not really suitable for a live site
• XAMPP an easy way to start

Part 2:
Backups
Friday, June 19, 2009

Keys to Success
• Should have both on-site and off-site
backups.
• Automated (if you have to think about it, it
won’t happen regularly)
• Test your system *before* you need it.
Friday, June 19, 2009

Local Backups
• rysnc to external drive
• Carbon Copy Cloner on Mac
• Other full-drive backups for Linux
• Complete local backup every week

rsync example

Offsite Backups
• option 1: backup to external drive, then
take offsite (storage, office, friend’s house)
• option 2: backup to online storage (s3,
another server, etc.)
Friday, June 19, 2009

Duplicity (+s3)
• Cross-platform (OSX and Linux at least)
• Can use any remote or local store, but I like
Amazon s3
• Duplicity creates encrypted tar-format
volumes and uploads to local or remote server
• Need gpg and other libraries
• http://duplicity.nongnu.org/

Duplicity Example
Friday, June 19, 2009

now automate it
• cron on *nix, osx < 10.4
• put in script in
/etc/cron/{daily/weekly/monthly}
• or use crontab
• launchd on osx >= 10.5
• Lingon, by Peter Borg
• http://tuppis.com/lingon/

Part 3:
Version Control
Friday, June 19, 2009

What is it?
• Stores your project files and manages
changes to those files.
• Makes deploying your projects much easier.
• Maintain a complete history of your
project.
• Just as important as backups.
Friday, June 19, 2009

Version Control Software
• git: http://git-scm.com/
• subversion: http://subversion.tigris.org/
• others: bazaar, mercurial, cvs
• lots of software integrates with VCS
Friday, June 19, 2009

How to Set up
• Server and client components.
• Can set up on own server.
• Or, use one of many hosted options
(github, devguard, unfuddle, etc.)
• git gui clients: git k, git gui, GitX (mac)
• subversion gui clients: rapidSVN, svnX
(mac), TortoiseSVN (win)
Friday, June 19, 2009

Subversion Example
• checking http://svnurl
svn co
out:
.
• commiting changes:
svn commit -m “commit message”
• updating:
svn update .
• get status:
svn status
