The latency between two servers located in two regions is normally higher than the latency between two servers located in the same data center or the same rack. High latency between application servers has a direct impact on the overall performance of the application. By placing applications servers in the same physical location, we can reduce the latency. When it comes to Azure VMs, we can…
