@Aleksejs Buzdins , Thanks for your patience and collaboration on this. To benefit the community, summarizing our offline discussion.
Azure Container Apps is not PCI DSS certified; this is a new service that is currently in Public Preview.
That said, that we’re always looking to increase the scope of Azure’s PCI certification and are continually reviewing services for inclusion into future assessments.
Please note that; as mentioned in this doc: - “It is important to understand that PCI DSS compliance status for Azure, OneDrive for Business, and SharePoint Online does not automatically translate to PCI DSS certification for the services that customers build or host on these platforms. Customers are responsible for ensuring that they achieve compliance with PCI DSS requirements. “
