gRPC and Protocol Buffers
In gRPCOpen source remote procedure call (RPC) framework that can run anywhere. It enables client and server applications to communicate transparently, and makes it easier to build connected systems. gRPC uses protocol buffers, Google's mature open source mechanism for serializing structured data — think XML, but smaller, faster, and simpler., a clientA desktop computer, laptop, smartphone or tablet, as well as any other electronic device that sends or receives data from a server. The term implies a connection to a wired or wireless network. application can directly call a method on a serverA computer that provides data to other computers. Many types of servers exist, including web servers, mail servers, and file servers. Each type runs software specific to the purpose of the server. For example, a Web server may run Apache HTTP Server or Microsoft IIS, which both provide access to websites over the Internet. A mail server may run a program like Exim or iMail, which provides SMTP services for sending and receiving email. A file server might use Samba or the operating system's built-in file sharing services to share files over a network. application on a different machine as if it were a local object, making it easier to create distributed applications and services. As in many RPC systems, gRPC is based around the idea of defining a service, specifying the methods that can be called remotely with their parameters and return types. On the server side (Token CloudFunctionality, data and resources running on physical and virtual servers maintained and controlled by Token, and accessed via an Internet connection.), the server implements this interface and runs a gRPC server to handle client calls. On the client side, the client has a stub that provides the same methods as the server.
Here's the best way to think about it (hover to enlarge):
Using protocol buffersSpecifies how serialized information is structured by defining message types in .proto files. Each protocol buffer message is a small logical record of information containing a series of name-value pairs. Protocol buffers have many advantages over XML for serializing structured data, including being simpler, 3 to 10 times smaller yet 20 to 100 times faster, all whilst being less ambiguous, in addition to generating data access classes that are easier to use programmatically. (or protobuffs, for short), serialized information is structured by defining protocol buffer message types in .proto files. Each protocol buffer message is a small logical record of information, containing a series of name-value pairs. A fairly simple example of a .proto file that defines a message containing information about a Token business member might look like this:
member_id = 1;
key_id = 2;
signature = 3;
memberId = 'member_id string',
keyId = 'key_id string',
signature = 'signature string'
