Like CPU and ram have a maximum value. If I want to produce this product,
provided to the cloud host users.  The maximum value is set to how much
more appropriate.

If the settings are too small, users want to dynamically add CPU or memory,
and can't meet the needs of users.

If the setting is too large, such as max memory set to 40G, current memory
is set to 2G, the virtual machine memory only 1G more, much less than 2G.
If this value is set too large,  Are there any other effects?

Ask your advice.
