title: Are the live connections dropped on azure while doing Blue Green deployment
body: <p>I am deploying my java rest services on  Azure App services, I am trying to understand blue green  deployment on azure, I read this official blog on Azure Blue Green : 
  <a href="https://%20https://azure.microsoft.com/en-in/blog/blue-green-deployments-using-azure-traffic-manager/" rel="nofollow noreferrer">https://azure.microsoft.com/en-in/blog/blue-green-deployments-using-azure-traffic-manager/</a></p>
  
  <p>I got the initial idea, but what if there are many live connections on Blue instance and new code is deployed on the green instance and after sanity testing, we swap blue with green. If there is any live connection on blue will it die or will it hold till it serves the meaning full response from the end service</p>
  
  <p>From swap I a mean the control button called Swap available on Azure App services. My main concern will there be any data lost while swapping when there is a live connection            </p>
