System topology describes the layout of applications, how they are connected to each other, and how they are currently performing in your system. A topology review enables companies to monitor the performance of all services, network devices, connections and applications. The seven types of topologies are as follows: bus, star, ring, point-to-point, tree, mesh and hybrid.
