Which benefit of network monitoring can lead to reduced AWS costs?

Network monitoring can lead to reduced AWS costs by focusing on the reduction of cross-availability-zone traffic. When applications are deployed across multiple availability zones (AZs) in AWS, inter-zone data transfer can incur significant costs. By using network monitoring tools to track and optimize traffic flows, organizations can identify and minimize unnecessary data transfer between these zones. This optimization not only improves performance by reducing latency but also significantly lowers operational expenses associated with data transfer charges.

On the other hand, improved application code quality, streamlined deployment processes, and increased server capacity do not directly address cost savings related to network traffic. Improved application code quality may enhance performance and reliability but does not necessarily impact AWS costs directly. Streamlined deployment processes focus on efficiency and speed of deployments rather than on the costs of data transfer. Increased server capacity could lead to more resources being provisioned, potentially raising costs rather than reducing them. Therefore, reducing cross-availability-zone traffic through effective monitoring is a specific benefit that can provide a tangible reduction in AWS expenditures.
