Use case : load balancing - easysoa/EasySOA GitHub Wiki

<<< Back to [Final soa model design](/easysoa/EasySOA/wiki/Final-soa-model-design)

Description

A company exposes an Endpoint for a web service, which is meant to be consumed by several Organizations. This endpoint is only a front-end that acts as a load balancer for multiple Endpoints that expose the same underlying web service.

Goals:

• Make EasySOA check the URLs configuration for the front-end, to ensure that all URLs lead to the same webservice, only on different endpoints?
• Be able to list all endpoints hidden behind the load-balancer, and make sure that they match the same service
• Monitor these endpoints to check their availabilty and the front-end respect of the SLR

Mapping to the model

• 1 Service "MyService"
  • 1 Deployable "MyServiceCode"
    • n DeployedDeployables on Production, that:
      • Exposes 1 "MyServiceCode" endpoint per deployed deliverable (total: n Endpoints)
  • 1 Deployable "LoadBalancer"
    • 1 DeployedDeployable on Production, that:
      • Exposes 1 "LoadBalancer" endpoint
      • Depends on n "MyServiceCode" endpoints
      • (EITHER not EasySOA-managed) Has the mappings specified by import/by hand on the DeployedDeliverable
      • (OR, EasySOA Integration) Has the mappings specified by import/by hand on the DeployedDeliverable, with the mappings being used to configure the load-balancer
      • 1 tailor-made ModelConstraint to make sure all endpoints we depend on are of the same implementation "MyServiceCode" of the Service
      • 1 (scheduled) SLR Validator to check for the quality of the service
