Optimization of integration flows in cloud environments

An integration flow is monitored to determine a processing location of a message. The integration flow includes a route, one or more nodes, and one or more secure connectors. A first message is received by the integration flow. A central processing unit serialization load is received including a serialization of the first message on a first secure connector and a deserialization of the first message on a second secure connector. A processing load of the first message running on a first node of the one or more nodes is received. A first threshold of a processing load of the first message is received. The first threshold is determined to have been reached. Based on the first threshold being reached, a processing location of the integration flow is altered such that the first message is processed on a second node of the one or more nodes.
