The two sets of graphics show the RPC and SOAP connections respectively.

In the animation, two computers labeled Application 1 and Application 2 are connected with a pair of arrows. The first arrow is labeled Request and the second arrow is labeled Response. These arrows are enclosed within a block labeled RPC.

On the right are two blocks, each of which contain two servers. The two blocks are labeled Site A and Site B. The servers are connected by arrows that pass through a cloud that has SOAP written in it.
