Cloud Application Integration (On-Premises) : Administering CloudStreams : Overview : About CloudStreams : Inbound Architecture
Inbound Architecture
In the inbound run-time scenario, a SaaS application invokes an on-premise application through CloudStreams as follows:
Step
Description
1
A SaaS application invokes a virtual service that has been deployed to CloudStreams. The virtual service's policy performs security checks and any other user-defined processing before sending the request to the on-premise application.
2
The virtual service invokes a service endpoint (an Integration Server flow service or a Java service) in the on-premise application.
3
The endpoint service then invokes the on-premise application service(s).
4
The on-premise application processes the request against the native service and sends a response back to the SaaS application.
5
The CloudStreams server collects run-time metrics and events, and publishes them to the CloudStreams Analytics facility, which is powered by Software AG MashZone. You can use the CloudStreams Analytics dashboard to monitor the metrics.
6
The virtual service logs the request/response transaction and its payload.
