IFO4
Loading...A grouping of compute instance types that share a common architecture and target workload profile, typically labelled by a letter prefix in the SKU naming. Instance family is the principal axis of compute pricing, performance characteristic, and reservation flexibility. The federation requires every Tier-1 service to publish its dominant instance family quarterly with sizing rationale and any cross-family migration plan under UFMS-001:2.4(d). Family migrations driven by price-performance ratio improvements are recorded in the architectural debt register where they require code change.
A taxonomy term from cloud provider documentation; the AWS instance family naming was the dominant influence on the broader vocabulary.
Federation members publish dominant instance family per Tier-1 service. Migration plans across families are tracked in the architectural debt register. Family-by-family fleet distribution is reported quarterly under MEV-Annex:3.2.
