Simple to start with
Able to grow
Easy to replace
Know what you are doing
Specific Technologies

Load balancing HAProxy, Pound, nginx
DB Clustering PgPool II, MySQL Proxy, Oracle cluster, Slony
Specific Technologies
Distributed Storage S3, Nirvanix
Computing EC2, GoGrid, AppEngine, Morph AppSpace/AppCloud
CDNAkamai, CoralCDN,Amazon CDN (coming soon)
How do you plan scaling?
No “one size-fits-all” solution - depends on the specific application
Check, measure, test and repeat
Start from real bottlenecks - not from assumptions
Choose the path of least resistance!
Easy vs. ComplexDo you know what’s easy?
Better code and caching covers 90% of scaling needs!
Web servers
Application servers
Messaging
Storage
Database
Don’t overdo itDo you really need the “it”?
20 machine DB cluster?
CDN for 10,000 pages a day?
Mirrored Messaging servers?
?
Future Proofing?
Can you estimate your future needs now?
Do you have time to test and analyze all scenarios?
Proven technology
Embrace Change
Repeatability - Testing
