Working in the cloud
We are from the internet — we know the
value of open source. Hardware and storage
is unfortunately real, but you can outsource it
all. This talk will guide you through how to
exploit cloud computing today to make you
happier and more efficient.

Amazon
Elastic Compute Cloud getting better
Elastic IPs
Dropped bandwidth price recently
New status page
Simple Storage Service pretty good
Net::Amazon::S3 retry => 1
Almost a CDN

Amazon S3

Scaling
Premature scaling is the root of all evil
EC2 + S3 annoying to scale
Best thing about App Engine is the data store
For big deployments, the cloud may not help

Data Protection
Uh-oh
Especially if your data is stored in another
country

Issues
Availibility
Reliability
Customisation
Keep everything inhouse
Worried about lock-in
SLA

Remember
Electricity is no longer a competitive advantage
All you need is a credit card
