Hosting Service History
Bought and hosted our own servers, load balancers, firewalls,
etc. at a colocation facility.
First moved to S3 as our CDN late 2008.
Complete EC2 migration in Q109.
All Amazon services combined (S3, EC2) saving us ~30%
month from our previous bandwidth + colo charges (racks,
power, etc).
Would have had to purchase additional rack servers based on
traffic, so we’ve saved an additional $10-20K since then.
EC2/S3 has replaced what was probably $250K in capital
expense.
We get substantial flexibility in scalability to support new big
deals.

Notes from Experience
EC2 has been great, S3 has been a huge win (music
streaming).
Database scalability – even X-large instances are memory.
constrained, especially for large table indexes. (Bring us larger
memory sizes, Amazon!)
There are some great open source tools out there…
S3 Organizer (Firefox plugin)
Elasticfox (Firefox plugin)
Large instances are 4x the cost… but for our app more than 4x
the performance. The reason – I/O.
We ended up using more instances than we thought we
would.
Service reliability has been excellent.
My operations team spends more time on the right things.
