    We have built a PASoe OE 11.7.7 with SCL app in Windows container based on windows server 2019.
    It runs OK but very slowly compared with a VM deployment of same same app.

    Has anyone successfully deployed a PASOE application in a windows container?

    Dear Raymond,

    When it has anything to do with Docker and OpenEdge I am mostly involved at Consultingwerk. 
    To my knowledge no-one has ever deployed a Windows based docker Image with a PASOE for anything else than research if the concept works. 

    In general, any type of virtualization implies between 20% and 40% performance loss compared to running on bare metal. 

    What is the main reason you would like to use a Windows based image?
    To me there are a number of advantages to execute the PASOE in a Linux based VM environment. One of the most important being, the ability to use the standardized and fully supported Pasoe Docker Image from dockerhub. 

    The SmartComponent Library back-end itself is platform independent so it runs both on Windows as on Linux without any issues. 

    BR Daniel

    Thanks Daniel.

    We need a windows container because our code is very old, and lax with regard to case of references. The Linux pas container works but we have not done enough testing with our codebase to be happy with it.  

    The problem we were/are having is to do with performance, but we have just realized that we are referencing large amounts of our code, and SCL code from Azure blob storage. Our containers run in Azure with Kubernetes. I will be rebuilding shortly with all code copied intoo the image.

    Thanks, and I will let you know how we get on

    We do not recommend the use of Windows containers - as it's not a supported platform for OpenEdge/PASOE.

    But maybe someone of the other customers present in this forum has experience. 

    If you isolate specific issues, we _may_  look into those. 

    With regards to your legacy codebase, you could contact us and we can provide you with an estimate for fixing that (semi-)automated based on Proparse. I'm pretty sure that being on a supported platform will have a strategic value for your business too.
