Environments

The solution maintains two isolated environments. Each has its own Azure resources, Pexip nodes, Genesys queues, and API credentials.

Layer	Test	Production
MaxConf API	api.test.vc.maxconf.ca	api.vc.maxconf.ca
MaxConf API (edge slot)	api.test.vc.maxconf.ca/edge	N/A
Pexip Conference Node	conference.test.vc.maxconf.ca	conference.vc.maxconf.ca
Genesys Queue	SBC_VBV_TEST	SBC_VBV_PROD
Genesys Org	maximuscanada	maximuscanada
Azure Subscription	Shared (resource-group isolated)	Shared (resource-group isolated)

Edge deployment slot

The Test environment includes an edge deployment slot on the Function App. Developers push to the edge branch to deploy new API code here before promoting to the main Test slot. This provides a pre-test integration surface without affecting the stable Test environment that IDIM connects to.

Promotion path

edge → Test → Staging (swap) → Production

Production deploys use the Azure Functions slot-swap model: code deploys to a staging slot, is validated, then swapped into the production slot. The previous production code remains on the staging slot for instant rollback.

Environment connections

Each MaxConf API environment connects to specific downstream systems:

MaxConf API	Pexip Infinity	Connected IAS Environments	BCSC Mobile App
Test/Edge	Test	DEV	None
Test	Test	DEV2, SIT, QA, PREPROD, Test	BCSC DEV, BCSC QA, BCSC Test
Production	Production	Production	BCSC Production

Genesys organizations

Maximus maintains two Genesys Cloud organizations, both deployed within Canadian AWS data centres (cac1 region):

• maximuscanada - Production and test queues; IDIM staff may be assigned for testing
• maximuscanada-dev - Internal development only (Maximus staff)

The Genesys web interface is accessed at https://apps.cac1.pure.cloud/.
