* For Azure Cloud connection, you need to provide your **service key** obtained from Azure Cloud first.\
  A **service key** (s-key) is a standard GUID to uniquely identify an ExpressRoute circuit.\
  A circuit is uniquely identified by a standard GUID called as a **service key (s-key).** The service key is the only piece of information exchanged between Zenlayer, Microsoft Azure, and you. The s-key isn't a secret for security purposes. There's a 1:1 mapping between an ExpressRoute circuit and the s-key.\
  Zenlayer will find a closest location to match according to your service key. Please ensure the format is correct.\
  See [<mark style="color:blue;">**Validate Cloud Connection**</mark>](https://docs.console.zenlayer.com/welcome/cloud-networking/get-started/validate-connection-in-public-cloud) to know how to obtain a service key.
