Measure Infrastructure Performance

Step No. 3: Measure infrastructure performance

Do you know how well your mission-critical business services are being delivered? The job of the network infrastructure is to take an IP packet from one end of the network and move it consistently and reliably to the other.

Do you have metrics for that process for all your key applications and remote sites? For instance, how is SAP performing across the network for your remote users? The question is not just, "Is it available or not?"

Calculating application response times across the network to users is a good starting point for understanding the before and after impact of change. This should include how much time an application is taking between tiers of a multitier application so you can determine whether a slowdown is in the network, server or application. In addition, establishing baselines for all critical applications is essential to understanding what "normal" performance is for each (and thus, being able to know when deviations occur).

Step No. 4: Monitor VOIP and video

Will voice and video traffic between the new entities impact data applications? Is your network prepared for a convergence of unified communications (UC) and data services? The addition of streaming application services such as voice over IP (VOIP) and video can negatively impact the performance of data applications. Your IT organization must constantly monitor response times, bandwidth consumption and service quality.
