In my last post I wrote about general concepts behind Function as a Service (FaaS) and my view on this application development style. As an example I used the basic pipes and filters concept implemented by Unix Shells and many shell commands. Within this post I will use the same example and implement it using a Function as a Service platform. To recap the scenario, we had a simple JSON file containing booking records. From this file we identified certain records based on purchased products. Afterwards we extracted customer emails which could be used as a list for targeted marketing.

Some see FaaS as an addition to today’s lightweight architectures, others see it as next step within the evolution of Cloud and IT.

The worklist application is the out of the box user interface of the human workflow engine. It allows users to view their pending tasks and work on them with the help of custom ADF Views. One important additional feature of the worklist application is the possibility to define rules that change automatically the task assignment if some conditions are met.
