OPEN ID, OAuth, OPEN ID Connect, Laravel Framework

Simple Terms

1. OpenID is about verifying a person's identity (authentication). (usually returns ID_TOKEN)
2. OAuth is about accessing a person's stuff (authorization). (NO ID_TOKEN but information got pulled)
3. OpenID Connect does both.

All three let a person give their username/password (or other credential) to a trusted authority instead of to a less trusted app.

https://security.stackexchange.com/questions/44611/difference-between-oauth-openid-and-openid-connect-in-very-simple-term

OAuth 2.0 is an authorization framework, not an authentication protocol. You can think of this framework as a common denominator for authorization. ... The big difference between OpenID Connect and OAuth2 is the id_token . There is no id_token defined in OAuth2 because the id_token is specific to federated authentication

Micro Services && RPC

.Net Core is open source:
https://github.com/dotnet/coreclr

MS stack:

IIS (Internet Information Service) ----- Apache equivalent

ASP.net(.net MVC framework with module to SQL db, ASP scripting language)  -------- PHP euqiavalent

IIS && APS.net can be replaced by .net core which runs on windows and Linux like GO replaces Apache and PHP on ubunutu

Micro Services:

In distributed computing, a remote procedure call (RPC) is when a computer program causes a procedure (subroutine) to execute in a different 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. That is, the programmer writes essentially the same code whether the subroutine is local to the executing program, or remote.^[1] This is a form of client–server interaction (caller is client, executor is server), typically implemented via a request–response message-passing system. In the object-oriented programming paradigm, RPC calls are represented by remote method invocation (RMI). The RP
