results = response.json()

3. Service Management

from service_bus import ServiceBus
from network_manager import NetworkManager

# Initialize service bus
service_bus = ServiceBus()
service_bus.start()

# Register service
network_manager = NetworkManager()
service_bus.register_service('network', network_manager)

# Start service with orchestration
service_bus.orchestrate_service_start('network')

# Get service status
status = service_bus.get_service_status_summary()
