+
+## Authorizations in Microservices
+
+While developing a monolithic application, managing authorizations and permissions is a bit easier, as you can have a single point of control for all the authorizations and permissions. However, microservices have become a bit more complex.
+
+In a microservices architecture, each service has its own database and logic for handling permissions. This can lead to a lot of duplication and inconsistency in the way permissions are managed across services. also, there will be an issue of sharing the permissions across services.
+
+One way to solve this issue is to use an authorization-as-service. This means that you have a separate service that is responsible for managing all the authorizations for all the services in your architecture.
+
+
+### POC
+
+Today I will do a quick proof of concept. I will use an open source that provide this functionality, there are a lot, 
+
+#### Some of Open source solutions
+- perimfy
+- openfga
+- casbin
+- topaz
+
+#### Cloud solutions
+- there are good cloud solutions like [Permit.io](https://www.permit.io)
+
+For today poc I will use [Permify](https://permify.co/).

+---
+
+1. Run the permify service on docker and expose HTTP and GRPC ports.
+
+![step](/images/journey/auth-1.png)
+---
+
+2. Created a new tenant at permify to store our policies
+
+![step](/images/journey/auth-2.png)
+---
+
+3. Created our schema, I used here the traditional RBAC model for simplicity. but in the real world and complex apps, there are a lot of models for complex use cases. Actually, Permify is considered as fine-grained access control service inspired by `Google’s Zanzibar`.
+
+    Permify has a gread article about their solution [Here](https://docs.permify.co/permify-overview/authorization-service)
