Serverless Functions

[Wan Li]

Hello,

I am wondering if anyone has utilized the IPF library to run as a serverless functions in the cloud? I am experimenting with the idea of utilizing AWS Lambda to receive the IHE SOAP messages using the IPF library to parse the XML into other formats, then sending that parsed data to another AWS Lambda for further processing and business logic.

Currently I have done so by having a class method implement the Lambda handler, then within that handler, call back via localhost to a spring boot app running within the lambda to query the CXF SOAP endpoint defined by IPF and have the IHE library perform the SOAP/XML processing. 

While it works, it seems like a hack and I'd much rather have the lambda handler trigger the SOAP processing directly rather than use localhost. I'm wondering if anyone else has used the IPF library in a serverless function and had good success?
