To operate a system effectively, it is essential to regularly monitor the operational statistics of the system you are managing. By routinely examining operational statistics, you can not only plan for future system expansion or upgrades but also react swiftly in case of abnormal situations.

One of the key metrics that is necessary for this purpose is the CPU metric. CPU metrics provide the fastest reflection of the system's load. Since you need to see the overall system status at a glance, the WhaTap Application Server Monitoring service displays it in the form of a histogram chart, as shown below. The chart represents the CPU distribution for customers operating approximately 50 to 100 systems.

Company A has built a stable system, but it appears that they have deployed an excessive number of systems in comparison to the service demand. This is a common occurrence, especially in manufacturing companies with limited IT expertise.

Company B's approach is more typical of traditional service-oriented companies. They maintain systems with a buffer to accommodate scenarios where loads increase. In the case of Company B, their services can experience CPU utilization that goes up to twice the usual level during periods of high demand.

Company C operates a cloud-based system, which differs from traditional systems in that they do not leave much room for excess capacity but rather employ a strategy of scaling up the system in response to additional load.

Traditionally, Company B's approach has been considered the most ideal for system operation. However, in recent times, there has been a shift towards the model used by Company C, especially with the adoption of cloud services. While there may be a perception that the cloud is more expensive compared to dedicated servers, its cost-effectiveness depends on how the operations team utilizes it. The cloud can be the fastest and most cost-efficient option depending on the specific use case and management strategies.

If you're curious about how your own system is being operated, you can use WhaTap server monitoring to check your system's operational status immediately. I recommend conducting a thorough system analysis through a 2-week free trial to gain a better understanding of its performance.
