Fills a specific growing need
 10K User Problem
– Huge number of simultaneous connections with high throughput
– Non-blocking, event-driven IO
 Scalable intermediary between device and data
 Glue to assemble other data sources
– Lightweight and efficient for distributed data
 Lets UI developers not have to wait for Java backend team…

Common Architectures & Deployments
 REST APIs used by a separate UI tier
 Often Stateless!
– User session state held in a separate cache
 Many stateless processes share a common stateful backend
 Lots of processes per machine

Cultural Changes
Systems Programmers
 Extensive Change Control
 Big infrequent releases
 “Beta” program, near end
 Test automation culture
Web Developers
 Commit into Prod(!)
 Deploy daily
 A/B testing in prod, always
 Test in the browser culture

Summary
A Few Words to Review
Big Changes with Node in Datacenter
Node in the datacanter brings operational challenges with new tools and technologies but also of cultural
changes involving “web development speeds” into traditional application management. Complex, rapidly
changing deployments are the standard.
