Editor's Notes

  1. Azure Container Service focusses on the configuration and management of the hosting infrastructure. We also provide key open source orchestration technologies. ACS does not provide an application development model. This has some advantages (e.g. more flexibility in application architecture) but some disadvantages (e.g. stateful applications need to be designed to manage their own state)
