I'm really looking forward to have FaaS on the OVH cloud and even proposed it last year but I have one concern.
Since those functions are stateless, it's required in most cases to interact with a database or, much more scalable, an object storage.
OVH already offers one but the latency is horrible (~200ms vs 30ms on Azure/AWS) and therefore a huge disadvantage. On the other hand, no competitor currently provides an object storage built on NVMe SSDs. So if OpenStack isn't the problem I highly suggest to launch a low-latency option together with OVH Functions. It would still be attractive at multiple times of the current price.
