Working with microservices can be challenging when it comes to shared capabilities like authorization. The domain of authorization is messy, with logic intertwined with domain-specific details and application data. Extracting a clean authorization service becomes complex due to overlapping data and messy separation. The ideal authorization capability should integrate easily with minimal overhead. This is where Polar, a logic language for expressing authorization, comes in. Polar allows multiple teams to build and run authorization models over multiple data stores. It simplifies authorization logic and removes redundancy, making it easier to implement complex authorization scenarios for applications like GitHub with a service-oriented architecture.
