Managing Microsoft Hybrid Clouds (2015)
Appendix A. Configuration Maximums
This appendix provides an overview of the configuration maximums of Microsoft Azure. The information in this appendix is useful for designing and managing an infrastructure running on Azure.
For some parts of the Azure subscription, soft limits are effective. If you want to increase a soft limit, contact Microsoft Azure support.
The limits are adjusted by Microsoft on a regular basis. Check this Microsoft article for the most up-to-date limits: http://azure.microsoft.com/en-us/documentation/articles/azure-subscription-service-limits/.
