Hi All, When we deploy API micro-gateway without complete container management system we do not have way to track all running instance details from central place. Sometimes all the deployments will not have enough resources to deploy container management system. In that case if we have some mechanism to run simple ballerina code within gateway itself that would be helpful. If we have something like that then when server starts up it can call some external service and confirm gateway existence. Also over the time it can do periodic call to external system and update it with aliveness. We can implement this feature in different ways. Push model and pull model both should work in this case.
Pull Model - The external system can call some API and based on the response trigger an action. In this case external system need to know IP address and port of each micro-gateway running in system. If we have controlled environment with fixed known number of gateways this will be good option. Push model - The external system opens some API to call to do an action. So in this case micro-gateway will call external and update about its aliveness. Advantage with this approach is central system do not need to know anything about gateways and running locations. We can start gateways anywhere and they will inform status to central system. In this case external system can be some monitoring tool, control point, service registry, management server or anything like that. We can see use-cases related to each of these. Having generic support with extension capability would be much useful here. Shall we let users to engage some kind of ballerina file when generate microgateway artifact? So when gateway runs it will call some init function and it can do some background work while gateway running. This capability will help us to do some additional stuff when we implement solutions. As example we can think of generating UUID during server startup and send it to some external system for tracking purpose.
