!!! Overview
[{$pagename}] ([RPC]) is when a computer program causes a [subroutine] to execute in another address space (commonly on another computer on a shared network), which is coded as if it were a normal (local) procedure call, without the programmer explicitly coding the details for the remote interaction. !! Why [{$pagename}] now? ([2017|Year 2017]) [1]
With all of this said, what makes [{$pagename}] and [gRPC] such a promising concept to bring back from the depths of proto-internet [protocols]? 

While much has been made of [REST] and other such frameworks, this work has been primarily in a space where computation power both in the [client] and the [server] has been rising dramatically. Since the advent of [RPC], both sides of the equation have only gotten more and more powerful, and so more power-hungry, large-scale solutions have been acceptable tradeoffs for what power they delivered.

There’s a huge monkey wrench in the mechanism, however — the [IoT], or [Internet of Things]. With so many [small sensors and microdevices|Constrained Nodes] utilizing [microservices] to compute massive amounts of [data], a need for small, power-efficient, yet still powerful [protocols] has given rise to the concept of [{$pagename}] once again.

The rise of the [IoT] actually mimics a lot of the what created [RPC] in the first place. [{$pagename}] was initially conceived of at a time where a mainframe provided more computing power than all the computers that would tie into it combined. The same can be said of the [IoT], where a device has just enough processing power to do a small, microscopic local call.

This is where [{$pagename}] shines — truly microscopic services work well with [RPC], and is what makes the concept poised for a strong comeback. Add this to the strong ability to internally connect cloud resources hosted by [Google] itself, and you’ve got a system of distributed computing that is greater than the sum of its parts, delivering effective, powerful computational weight to even the smallest of devices.
