I wish I did. I've spent a lifetime coming up with solutions including languages, app environments and service models that abstract away the difficulties. There exist such models now (didn't 15 years ago) that do some of the work, but they're always designed around some particular problem (clustering and provisioning for instance) and do only part of the job.

The whole job, eg for a service model, includes RAS stuff like failing over and restarting client requests transparently, WITHOUT requiring the service code itself to deal with any of that. I guess Ehrlang and kin are the most recent take on that, meaning an app environment that completely abstracts the parallelism and fault recovery.
