This project provides a middleware service for monitoring the execution of individual functions of a serverless application. It supports monitoring of functions on all widely-known FaaS systems AWS Lambda, IBM Cloud Functions, Google Cloud Functions, and Microzoft Azure Functions.
FTjFaaS is an integrated part of the xAFCL Enactment Engine (xAFCL EE), which can simultaneously execute individual functions of a serverless workflow application (Function Choreographies - FCs) across multiple FaaS systems and define and apply fault tolerance for each function of the FC.
FTjFaaS integrates the component jFaaS for portable execution of individual FC functions (supported all widely-known FaaS systems AWS Lambda, IBM Cloud Functions, Google Cloud Functions, Microzoft Azure Functions, and Alibaba).
FTjFaaS introduces a single InvokeMonitor interface, which is implemented in LambdaMonitor, OpenWhiskMonitor, GoogleFunctionMonitor, and AzureMonitor classes for each FaaS system respectively.
