Proxy Servers Reduce load on application servers Content caching Varnish, Squid, even home made Tuesday, June 23, 2009
Heavy Read Loads Replicate for heavy read load Denormalization Collapse data into fewer tables Duplicating data is OK. Cache as needed Tuesday, June 23, 2009
Heavy Write Loads Separate primary data storage (“write” servers) and read servers Write data out of band Tuesday, June 23, 2009
Testing Decide how big you want to scale Benchmark the actual application Test against production environment Determine acceptable load Use a service (Keynote, Gomez) Tuesday, June 23, 2009
