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

● Infrastructure provides servers

● Every server boots with one //:14777/

● Auto-register server with Controller

● Controller synchronizes servers with

load balancers

● Controller manages the state of

servers

● Controller automates workflows

● Orchestration becomes automatic

● Relieve from small operation details

● Focus on a higher-level

○ Automation Process

○ Disaster Recovery

○ Failure Mitigation

○ Monitoring
