I set up an EC2-Instances at AWS and SSH-ed into the machine and set up a simple httpd service. On viewing the apache log in which i make multiple concurrent requests to the "index.html" file from my local machine (Google whatsmyip = 218.x.x.182), i realize that the IP address is different and there are 2 (203.x.x.130 , 203.x.x.30). Is there some sort of load balancer working backend or this is an intended behaviour?
