Azure limit on maximum IaaS instances per cloud service

Hi,

We have a situation where we need 100 VMs inside the same cloud service. I have few doubts:

1.  We have hit the limit of maximum number of IaaS instances per cloud service (50). Is this a soft limit that can be increased by contacting Azure support?

2. Is there any limit on maximum total outbound data throughput (or total internet connectivity speed) for a cloud service that we should be aware of?

Thanks,

Vijay
