Documenting the Experience: Moving Crunchtools to Containers/OpenShift: Part 1

Background Last week, I was in Westford, MA for an engineering meeting. I was chatting with one of our Base Runtime engineers Petr Sabata, and an interesting subject came up. He joked, “I understand containers, I know how to use them, but I still haven’t converted any of *my* services to containers.” This got me

Core Builds in the Age of Service

Core Builds in the Age of Service

Background As legacy applications are redesigned for the cloud, they are converted to run in a stateless manner.
