This becomes really important for cache solutions like Redis™. AWS Security Groups and Azure Network Security Groups allow you to lock down access to your servers through advanced virtual firewalls.

Instead, focus on understanding what the workloads exercise to help us determine how to best use them to aid our performance assessment. For the network, we can use Iperf to assess the network bandwidth between the client and the database server to ensure it will be enough to meet our peak requirement.
