How do you authenticate a micro service?
Through mutual SSL, mutual authentication between microservices can be achieved, and data transmission between microservices can be encrypted through TLS. A certificate needs to be generated for each microservice, and the microservices are authenticated with each other’s certificates.
JSON Web Tokens: overwhelming advantages ared to SAML applications. JSON Web Tokens thus appear to be the most appropriate option for user authentication in microservices environments. More information on JSON Web Tokens can be found at http://jwt.io and in RFC 7519.
Should authentication be its own microservice?
Each microservice needs to implement its own independent security and enforce it on each entry-point. Each microservice depends on user authentication data, which it doesn’t own. It’s hard to maintain and monitor. Authentication should be a global solution and handle as a cross-cutting concern.
Is microservices are independently deployable?
Microservices solve these challenges of monolithic systems by being as modular as possible. In the simplest form, they help build an application as a suite of small services, each running in its own process and are independently deployable.
What is the microservice authentication strategy in Stack Overflow?
In this strategy, the authentication app is one service among other. But each service must be able to make the conversion session_id => user_id so it must be dead simple. That’s why I thought of Redis, that would store the key:value session_id:user_id.
What does Auth-Z mean in microservice architecture?
Auth-Z refers to what the user is authorized to do. The diagram below is a conceptual diagram of a Single-Page Application (SPA) that is driven by a Microservice architecture. This architecture utilizes an “edge” service, that provides “security” and “routing” in front of the microservice infrastructure downstream.
How does a microservice authenticate a user on Redis?
User will be authenticated by IDP and will get the JWT token from authorization server. Now API gateway system can store this token in Redis database and set the cookie on the browser. API gateway will use the cookie to validate the user request and will send the token to the Microservices.
What is single sign on in microservice architecture?
The only SO post I found on the topic is this one: Single Sign-On in Microservice Architecture My idea here is to have in each service (eg. authentication, messaging, notification, profile etc.) a unique reference to each user (quite logically then his user_id) and the possibility to get the current user’s id if logged in.
