Who are you?

What is Immutant?

• 1.x: Application server built on JBoss AS
• 2.x: Collection of jars that provide similar services

Why the change?

• a more traditional workflow
  • no install step
  • application server optional
• avoids a plethora of AS issues
• support multiple AS versions
• easier to support
• plays nice with popular libs, e.g. Component

Why use a container?

• Web session replication
• Load-balanced message distribution
• Highly-available “singleton” scheduled jobs
• Highly-available daemons
• Flexible Infinispan cache replication
• Multiple polyglot app deployments

Other changes

• consistent API
• less cruft
• usable as uberjar
• LGPL -> ASL
• lein plugin only required to deploy to application server
• wunderboss
