Processflow is a visual representation of a business process integration, which helps you as an user to orchestrate a business process in such a way so that you can modularize and control the complexity of business integration properly. A processflow, under the hood creates a micro-service architecture that can run in cloud servers or on premise getting or pushing data directly to the applications in execution and generate both transactional and data logs. In this article, we will see how the architecture of APPSeCONNECT processflow is laid out such that we can understand the under the hood big picture of the processflow.
When a processflow is getting executed, there are a number of things that can happen. First, an execution can happen on cloud directly on an hosted environment maintained by APPSeCONNECT, or it can generate a call to your own on-premise environment and execute the business flow using our APPSeCONNECT integration tool.
When the user triggers a processflow manually (or APPSeCONNECT Scheduler triggers it for you), the first thing
it tries to do, is to identify the environment(s) on which the processflow needs to be executed on. It can either
execute itself on APPSeCONNECT cloud premise on an hosted agent, or on-premise environment where the agent
is installed. The processflow starts with
Start node and execute each links to find the next node.
The nodes plays a vital role in a processflow determining what action it needs to execute, and passing or delegating
activities to different workloads.
The processflow engine takes care of each and every task or activity that needs to be executed on the platform. The engine takes help of Adapter to call individual Applications to invoke Get or Post actions. The engine calls the adapters, execute storage plugins, triggers notification, generate logs etc.
If there is any cloud involvement from an on-premise execution or an on-premise dependency for a cloud solution, it triggers the call automatically using Service Bus and executes the process.
The repository services takes care of storage and snapshot of the processflow executions which one can investigate later.
