Google gRPC vs JSON

gRPC 1.0 is Ready for Production @ InfoQ
"gRPC is a platform-neutral RPC system that uses the Protocol Buffers IDL to define end-point services and message payloads to be transferred, then generating stubs for multiple languages. gRPC supports 10 languages - C, C++, C#, Go, Java (including Java/Android), Node.js, Objective-C, PHP, Python, and Ruby – on Linux, Mac and Windows. There are native implementations in C, Go and Java, and wrappers around the C library for the other languages."

"Remote Procedure Calls (RPCs) provide a useful abstraction for building distributed applications and services. The libraries in this repository provide a concrete implementation of the gRPC protocol, layered over HTTP/2. These libraries enable communication between clients and servers using any combination of the supported languages."
"Protocol Buffers (a.k.a., protobuf) are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. You can find protobuf's documentation on the Google Developers site."

"what is behind this improvement. There are two major factors at work here: more efficient data encoding and HTTP/2. gRPC keeps data in binary both in client memory and on the wire by building on HTTP/2 and Protocol Buffers. This eliminates processing and space required for string encoding schemes such as Base64 or JSON. In addition, HTTP/2 itself makes things go faster with multiplexed requests over a single connection and header compression."

Is It Better to Rent or Buy? - The New York Times
"The choice between buying a home and renting one is among the biggest financial decisions that many adults make. But the costs of buying are more varied and complicated than for renting, making it hard to tell which is a better deal. To help you answer this question, our calculator takes the most important costs associated with buying a house and computes the equivalent monthly rent."
