Motivations For AS7 • Improve Usability • Increase Manageability • Simplify Configurations • Highly Performant - GO FAST!Sunday, June 19, 2011

Key Features of AS7Sunday, June 19, 2011

Key Features of AS7 • Fast and Lightweight • Supports domain (multi-node) management • Multiple consistent management interfaces • CLI, Java API, HTTP API, Console • Unified, user-focused configuration • Modular • Only APIs, no AS implementation exposure • True isolationSunday, June 19, 2011

Two Operational ModesSunday, June 19, 2011

Two Operational Modes • Standalone • Traditional JBoss single JVM server • Management facilities IN-VMSunday, June 19, 2011

Two Operational Modes • Standalone • Traditional JBoss single JVM server • Management facilities IN-VM • Domain • Multi-JVM, multi-server model • Management coordinated by Domain Controller Process • Multiple server instances (JVMs) per Host • Full lifecycle managed by Process ControllerSunday, June 19, 2011

Standalone Mode • Standalone is a single AS process for use in development, where the additional management functionality is not required • Provides a similar development experience to previous versions of the AS, allowing for a deployment to be dropped in the deployments folder and automatically deployed • Can still be managed by the same tools and APIs as domain modeSunday, June 19, 2011

Domain Mode • Easy management of multiple AS instances • Managed from a single point, all have access to the same domain configuration • Allows for management and configuration updates to be pushed out to all servers • Domain Mode has three separate processes: • Process Controller • Host Controller • Server InstanceSunday, June 19, 2011

Domain Mode ProcessesSunday, June 19, 2011

Domain Mode Processes • Process Controller • Responsible for managing and starting / restarting processes • Extremely simple, not much that can go wrongSunday, June 19, 2011

Domain Mode Processes • Process Controller • Responsible for managing and starting / restarting processes • Extremely simple, not much that can go wrong • Host Controller • One host controller is the domain controller, the rest are slaves • Domain controller is responsible for pushing out configuration changes over the domainSunday, June 19, 2011
