What is a server?
Development
● Um, huh?!
● … pause …
● We deliver to Ops.
● They deploy!
Operations
● What version to install
● What process to start
● Which data to use
● How to access logs
● How to monitor
● How to sync load
balancers

JVM Management with JVM
Service Provider Interfaces (SPI)
● A factory for an installation
● A factory for an running application
instance
● A factory for processes of an instance
● Generic RESTful operations
● Generic and standard endpoints: logs,
monitors, resources
App
java.lang.ProcessSPI

Deployment is a development responsibility
Development
● Does it have //:14777/?

● Tested and Integrated?
● Locally Deployable?
● Deliver to Ops.
● They Deploy!
Operations
● What version to install
● What process to start
● Which data to use
● How to access logs
● How to monitor
● How to sync load
balancers
Does it really matter now what’s beneath //:14777/ ?!
