Reserved capacity packages are pools of virtual machine resources. You can provision and de-provision any combination of virtual machines within your reservation package pool limits for a 6- or 12-month period. A pool consists of one or more units of capacity. One reserved capacity unit includes:

64 virtual CPUs

96 GB of memory

9,600 GB of storage

You may order as many reserved capacity units as you like. You pay a monthly fee for the reservation, but get discounted usage rates on the virtual machines you provision within the pool limits. You are not committed to use or pay for a fixed number of virtual machine hours during the 6- or 12-month period.
