Policy Centralization (Erl)
How can policies be normalized and consistently enforced across multiple services?
Policies that apply to multiple services can introduce redundancy and inconsistency within service logic and contracts.
Global or domain-specific policies can be isolated and applied to multiple services.
Up-front analysis effort specific to defining and establishing reusable policies is recommended, and an appropriate policy enforcement framework is required.
Policy frameworks can introduce performance overhead and may impose dependencies on proprietary technologies. There is also the risk of conflict between centralized and service-specific policies.
