Permify API provides various functionalities around authorization such as performing access checks, reading and writing relation tuples, expanding your permissions (schema actions), and more.
We structured Permify API in 4 core parts:
- PermissionService: Consists access control requests and options.
- DataService: Authorization data operations such as creating, deleting and reading relational tuples and attributes.
- BundleService: Facilitates the creation and execution of bundles that perform predefined operations, establishing relationships and attributes based on provided arguments.
- SchemaService: Modeling and Permify Schema related functionalities including configuration and auditing.
- TenancyService: Consists tenant operations such as creating, deleting and listing.
Our software does not include built-in support for service meshes (eg. Istio).
However, since it communicates using standard protocols like gRPC and HTTP, it is compatible with Istio and similar service meshes. Users will need to configure their service mesh setup manually to manage traffic for our software within their deployment environment.
- Configure your authorization model with Schema Write
- Write relational tuples with Write Data
- Read relation tuples and filter them with Read Relationships
- Check access with Check API
- Check entities permissions with Lookup Entity
- Check subject permissions with Lookup Subject
- Delete relation tuples with Delete Tuple
- Expand schema actions with Expand API
- Watch changes in the relation tuples in real-time with Watch API
You can secure APIs with our authentication methods; Open ID Connect or Pre Shared Keys. They can be configurable with flags or using configuration yaml file. See more details how to enable authentication from Configuration Options
To access the endpoints after enabling authentication, it's necessary to provide a Bearer Token for identification. If your using golang or nodeJs client library, an authentication token can be provided via interceptors. You can find details in the clients' documentation.
Availability of the Service
For our dedicated instance service we do have 99.9% level of availability and to assure this level of availability, we employ several strategies:
- Redundancy: We deploy our system across multiple Availability Zones in a region, ensuring that it remains operational even if one zone experiences issues.
- Load Balancing: Load balancers are used to distribute traffic across multiple instances of the service, ensuring that no single instance becomes a bottleneck.
- Auto-Scaling: Our system is capable of scaling automatically based on the incoming load, ensuring that we have sufficient capacity to handle any increase in traffic.
- Data Replication: Our PostgreSQL database replicates data to ensure its availability even in the event of a single-node failure.
- Backup and Recovery: Regular backups are maintained, and our system supports a robust recovery strategy in case of significant failures.
- Monitoring & Alerts: Using tools like Amazon CloudWatch, we monitor the health and performance of our system and can quickly respond to any detected issues.
Service Credits for Availability Failures
In case of availability failures, Permify's Service Level Agreement (SLA) provides for Service Credits which are applied as a discount on your future bills:
- If uptime is less than 99.95% but above or equal to 99.0%, you get a 10% Service Credit.
- If uptime is less than 99.0%, you get a 25% Service Credit.
- If uptime is less than 95.0%, you get a 100% Service Credit.
These credits are your sole remedy for any availability failures under our SLA.
