The IFS Cloud 25R2 Sizing Guide will be part of the technical documentation for 25R2, which is published around the release dates:
Early Availability (EA): October 16, 2025
General Availability (GA): November 27, 2025.
Currently, the Platform & Sizing section in the technical documentation states that the sizing guide is continuously updated as IFS gains more experience and introduces new deployment options. This means the official sizing guide for 25R2 will be available in the IFS Technical Documentation portal once GA is live or shortly before it.
