Secure deployment of an application across deployment locations

Methods and systems are provided for secure deployment of an application across deployment locations. Aspects include providing an application for analysis wherein the application is capable of being divided into processing nodes which can be deployed in different locations. The application processes messages based on message models having annotations defining constraints on the deployment of data in given data aspects. The data aspects include the entire message or data fields, data elements or data structures of the message. Aspects also includes analyzing the application to identify processing nodes that reference the given data aspects having deployment constraints and determining a restriction for a processing node based on the deployment constraints of the referenced data aspects. Aspects further include deploying each processing node of the application according to the determined restriction.
