Here are supported footprints of Communication Manager ISO on:
  • Amazon Web Services (AWS)
  • Microsoft Azure (Azure)
  • Google Cloud Platform (GCP)
Note:
Specifications for Avaya Aura® applications on IBM Cloud for VMware Solutions is same as that of the Virtualized Environment offer.
For IBM Cloud for VMware Solutions, instance type is not applicable.
Avaya Aura® Communication Manager supports VMware hosts with Hyperthreading enabled at the BIOS level.
Note:
The partitions size can be larger than the values listed in the following table.

GCP ISO instance type
  • E2-custom-2- 5120 (2 vCPUs, 5-GiB memory)
  • E2-standard-4 (4 vCPUs, 16-GiB memory)
  • E2-custom-4 (4 vCPUs, 16-GB memory)
  • N2-custom-4 (4 vCPUs, 16-GB memory)
Note:
In Microsoft Azure, you must provide an additional 16 GiB of disk space as the Communication Manager does not fully utilize the existing /usr partition, and the installer also ignores the /usr partition.
A gibibyte = 10243 and gigabyte = 10003
The terms mebibyte and megabyte are closely related and often used as synonyms, though they don't technically refer to the same amount of capacity. However, they are close in size, One mebibyte equals 1.048576 megabytes.
