![]() ![]() If the results didn't match, they'd raise an alert for further investigation. Once they established that this change was safe, they started reading from the actual external service in "dark mode." In this mode, they read the permission check result from both the new service and the existing web app, but without using the new service's result. They rolled out this change to their internal workspace and then to pilot customers. First, they created a loopback gRPC service that lived inside the Slack web app. To reduce the risk of deploying the permission system in a way that would disrupt users, Slack engineers opted for a staged deployment scheme. ![]() The client reads permission information from this cache to optimize for low latency.īackward compatibility was a significant consideration for the slack engineers. The backend maintains this permission set in Slack's Flannel edge cache and updates it near real-time. On the other hand, the display in the Slack client is based on a non-authoritative copy of the permission set. Slack always makes an authoritative check with the permissions service when a user takes action to ensure that the user can perform that action. Then, they grant users one or more of these roles on a specific context or entity (an organization, a workspace, etc.). Slack opted to create a Role-Based Access Control (RBAC) system, where admins define roles, which are a set of permissions for actions in the system. (.) We needed to build a system that was more flexible and allowed for granular permissions. The standard types of roles we offered to customers were too broad, and delegating a generic admin role can grant someone with too much power - what if you only want a specific user to be able to manage specific channels? When you make them an admin, they can perform a wide variety of actions beyond the scope of the intended purpose. Medina explain the motivation for creating a new role management system: Slack engineers Jake Byman, Aish Raj Dahal, and Jose M. As a result, its customers' admins can now have granular control over what their users can do. It created a custom containerized Go-based permission service that integrates with its existing systems over gRPC. Slack needed to build a system that was more flexible than the one it previously had.
