Today's demand for data centers is solid and effective, and this should be done first by "reasonable use". While idle resources are a waste of money for an environment. But if you fail to make a reasonable resource allocation to the frequently used data center, it will lead to a dangerous scene. A single hardware failure may cause other physical hosts to fail. The challenge for IT managers is to use and manage computing resources across the entire environment (usually including physical, virtual, and cloud resources). This article will discuss resource planning and problem mitigation as a means to achieve the goal of resource optimization. We will also ...

The author of this article details a rationing performance test method that you can use to determine where the rationing performance lag occurs. This article describes a rationing performance test method that you can use to determine which locations are lagging behind in cloud allocation performance. The purpose of this rationing performance test is to measure the total ration time from the user's perspective in an end-to-end manner. When multiple rationing is present, the trend of rationing time is judged. The entire allocation time is decomposed into several parts to determine which components and steps occupy the most performance overhead. Get component-level queues when there are many rationing requests in the system ...
