In our situation, the app (the Client), needs to access the email account (the Resource Server) to collect emails before it can organize them to create the notification system. Resource Server (RS): where the actual service is stored.Authorization Service (AS): OAuth 2.0 server.OAuth has the following four main actors: Assume we need to access a user’s email account for a simple app that organizes a user’s email - perhaps to send SMS messages as notifications. To understand this process we’ll first lay out a standard OAuth flow for a simple use case. Considering OAuth as a Delegation protocol can assist in the creation of scalable microservices or APIs. In the web realm, the underlying message is there, yet it also means having the ability to offer, accept, or deny the exchange of data. In the real world, delegation is where you delegate someone to do something for you. Jacob Ideskog of Curity believes that to accomplish this OAuth should be interpreted not as Authentication, and not as Authorization, but as Delegation. There is a method that allows one to combine the benefits of isolated deployment with the ease of a federated identity. The Solution: OAuth As A Delegation Protocol This would involve calling an Authentication Service to populate the object to handle the request and respond in every single instance. Having an independent security barrier - or request handler - for each service to authenticate identity is unnecessary. If the same technique were to be applied to individual microservices, it would be grossly inefficient.

In this article we’ll identify how to implement OAuth and OpenID Connect flows using JSON Web Tokens to achieve the end goal of creating a distributed authentication mechanism for microservices - a process of managing identity where everything is self-contained, standardized, secure, and best of all - easy to replicate. There are smart techniques that leverage common technologies to not only authorize but perform delegation across your entire system.

Should each service have it’s own independent security firewall? How should identity be distributed between microservices and throughout my entire system? What is the most efficient method for the exchange of user data? Unlike a traditional monolithic structure that may have a single security portal, microservices pose many problems.

Perhaps the reason is that people are unclear on how these services talk to one another especially tricky is properly maintaining identity and access management throughout a sea of independent services. Everyone’s excited about microservices, but actual implementation is sparse.
