In the last section of the chapter, we dealt with the various aspects of the subject of connectivity,  symbolically, the traffic network (or the road network) between the individual corner points of our VNets.

In this section, we will take a step forward and deal with topics such as routing and load balancing, and stay in the picture with traffic planning or traffic control.

The section itself is divided into two parts:

• Some theory about routing and so on
• Three specific offers of the Azure platform (Azure Load Balancer, Azure Traffic Manager, and Azure Application Gateway)
