Should organizations interested in edge computing wait for a best-of-breed app to emerge?

No, you should not wait. You might not get the perfect implementation on the first interaction but as long as you improve it and are driving it in the right direction you will be in a better overall sport. A lot depends on what you want to achieve with edge computing. There are lots of examples of a successful edge implementation in various industries and verticals. 

If you have a use case for being at the edge, don’t hesitate to pursue it. It’s a noisy space, and the solution landscape is frightening in its complexity and diversity, but that shouldn’t stop you. When you have a defined opportunity for an IT solution, even a solution that’s less than perfect is often better than not having one at all.
