Described are software stacks for accepting and implementing portable packages containing encodings of processes. The packages are portable and distinct from the technology stacks. The packages may be in the form of declarative code for configuring the technology stacks and can be plugged into the technology stacks to allow the technology stack to play the packages, thereby automating the processes encoded by the packages. The technology stacks have components that are declaratively configurable such that they can provide their functionality autonomously and yet can also, as a unit, in performing their respective functions, cooperatively perform the processes encoded by the packages.
