Agenda
• What is Payara?
• MicroServices Demo from PI to Cloud
• Questions

3.
Payara Server
• Open Source Application Server Derived from GlassFish
• Traditional Domain Deployments
• Drop in replacement for Open Source GlassFish Server 4.x
• Additional Enhancements, Bug Fixes
• Fully Supported

4.
Payara Micro
• Simplified Runtime for Java EE developers
• Small Footprint (<70MB jar; < 50MB Heap)
• Based on Payara Server
• Scales from Raspberry Pi to Large Data Grid
• Designed for Cloud Native and Container Deployments
• Run Java EE applications from the Command Line
java –jar payara-micro.jar –deploy example-app.war

5.
Payara Micro – Key Features
• Elastic Clustering
• Cluster-wide CDI Events
• Embedded Data Grid (JCache Support)
• Web Profile APIs
• Additional APIs
• JCA Inbound/Outbound
• JBatch
• ConcurrencyJCache
