These are slides from a class I presented alumni and incoming students at the Austin Center for Design. The goal was to provide an over view of software application development (architecture, languages, frameworks), how to augment your development with other people of shops, and some basic techniques for scaling up.

More Concurrency
Remember hosting?

load balancer
Virtual servers: add more virtual servers
behind a virtual load balancer
App platforms: press a button (in theory)
Failover
Geographic redundancy
Sticky Sessions

Database
Add indices
(or remove them)
Find and optimize slow queries
Avoid the N+1 problem
Eager loading
Add databases:
Master and slave (and slave and slave)
Clusters
Vertical partitioning
Horizontal partitioning (sharding)
