Glossary term

Cross-AZ traffic

Data moving between availability zones (separate data centres) in the same region. AWS charges about $0.01 per GB in each direction, GCP about $0.01 per GiB, and Azure has not charged for it since May 2024. Why it matters: Chatty services spread across zones can run up a large, hard-to-see network bill.
