Multi-Cloud Rosetta Stone

While some terms across the cloud computing industry are standard, such as a firewall or IP address, Aviatrix works with multiple CSPs (Cloud Service Providers) who use different vocabulary for similar concepts. This document gives you, an Aviatrix user, a comprehensive list of common cloud computing terms and their synonyms.
