Manager
• Entry point for clients and containers• Provides “information” about services and
components (references)• At least one manager per system, but could
be more• Implemented in Java• start: acsStartManager• stop: acsStopManager

• Instances are numbers: 0 - 9
• Resources (ports) configuration for:– services
– manager
