The total volume of computing resources allocated to each service is fixed, and they are static. A tenant can exclusively use or share a service to obtain the resources required for running this service.</p>

<p id="admin_guide_000018__a37550a1020454a73969458149b16c472">If fixed resources are allocated to each service, the following problems may occur:</p>
