Today: Advanced Scaling with PaaSautomated app scaling
New Relic integration
performance instrumentation
stress tools
Instant App Scaling
one-click spawn multiple instances
rapid launch by copying existing instance
adjust resource allocation too
scriptable, can be automated
can trigger “autoscaling” events
Automating Scaling
Cloud Controller sits behind REST api
External apps call api in response to events or thresholds
Client can be anything that talks HTTP
Automated Scaling and New Relic
Demo: ab and JMeter
Log Aggregation
collect all logs from all app instances
forward to aggregation service
no SPOF
logs available via web ui, command line, and REST API
log streams can be filtered and formatted
can generate json logs
Demo: Logging to Loggly
