auth and authz
  • ceneterlized authentication and authorization server.
  • simple interface to configure clients permision.
  • permision changes should propagated immediately e.g. api_rate_limit
  • no username/password send throw wires, tokens instead
  • token is generated using secret keys, which change automtically. whithout effecting any client
  • should use the right application and have the right permission to do anything
  • no need to hit auth server everytime you need to check the permission of your client rfc7519
  • no more than 25ms for doing authentication, is it to low?
  • easy use solution, proivide shared libraries(based in your programming language to use)
