This document discusses hybrid connectivity options for connecting on-premises resources to Azure, including Azure Relay, Service Bus, API Management, and networking. It provides an overview of WCF relays and hybrid connections in Azure Relay, messaging capabilities in Service Bus, and how API Management and networking options can enable hybrid scenarios with varying levels of required development and network configuration changes. Tables are included comparing features and requirements of the different options.
