Unlike the last two enterprise deployment patterns, cloud software vendors will typically use an inverted pattern designed to streamline the creation of a data pipeline to their end-users’ data. It is inverted in the sense that Hybrid Data Pipeline is hosted in the cloud, rather than on-premises or in a DMZ.

Figure 4 represents a typical deployment that a cloud ISV might use when integrating with legacy customer data residing behind a firewall. In this diagram, an OPC is white labeled and deployed at each end-user site, allowing the ISV to access this data from the cloud. Typically, the ISV will use this setup to provide real-time access to on-premises data, as external data objects without duplicating the data. Or, the ISV may want to start ingesting this data for analytics or data management, or to facilitate migration from on-premises systems to a hybrid or pure cloud deployment.
