We are developing the application which supports both mobile and web application in google app engine. Most of the things are developed using google cloud endpoints, is there any performance effect using the endpoints in web applications. As an average we are using 10-15 endpoints in browser web page using google javascript endpoint library. these endpoints need to refresh data from server for certain interval of time. Is it causes performance effect.
Could you please suggest us, is there any better and securely implement applications which support both mobile and web application.
