We enable Key Vault for protecting the keys and making it centralized, although there is no such request from the customer to implement and configure it. The infrastructure is using Key Vault, but inside Azure Stack Hub, not within public Azure. We have certifications such as CSA 270017, 270018, and 27001, focusing on enterprise compliance for other platforms, but Azure Stack Hub usually applies cloud certification from CSA. The pricing is expensive, especially today as most platforms embrace cloud models, promoting different stacks that support heterogeneous hardware and hybrid model environments, offering full multi-tenancy. While the demand is huge in Saudi Arabia with significant requirements, the pricing and product aren't very sellable or profitable. This is partly due to hardware restrictions and Microsoft licensing. GPU as a service is what I'm referring to. If I want to run an in-house application on Azure Stack Hub, I cannot enable it without changing the whole platform and the hardware, as the GPUs are absent and cannot be added to the existing setup. On a scale of one to ten, I would give Azure Stack a rating of seven.
