Platform overview
Ably’s platform enables data to be streamed between all internet-connected devices, such as browsers, servers and mobile phones. It offers enterprise-scale messaging that automatically scales to meet demand, a highly-available service, message delivery guarantees, and low latency across the globe. Ably is engineered around the following four key principles to ensure the dependability of its service:Performance
High performance ensures that the end-to-end latency and bandwidth for data sent via the platform is minimized, and maintained at scale.
Integrity
Provides guarantees for the realtime messages sent using the Ably platform so that you don’t need to handle missed, duplicated or unordered messages yourself.
Reliability
A fault-tolerant platform is reliable by ensuring that there is sufficient redundancy at a regional and global level to provide continuity of service in the face of infrastructure failures.
Availability
The Ably platform is designed to be elastic and highly-available so that you can use it at any time, even under high load.
Core capabilities
Enterprise-scale messaging
Ably serves billions of devices monthly and delivers over half a trillion messages monthly. The platform is built to handle massive scale while maintaining consistent performance and reliability.Automatic scaling
The platform automatically scales to meet demand, ensuring that your applications can grow without infrastructure constraints. Resources are provisioned on demand as load changes, eliminating the need for capacity planning.Message delivery guarantees
Ably provides:- Exactly-once delivery semantics: Messages are delivered once and only once to subscribers
- Guaranteed message ordering: Messages arrive in the order they were published
- 100% message delivery guarantee: Through multi-region redundancy, Ably ensures messages are never lost
- 99.999999% message survivability: Statistical guarantee for message availability
Global low latency
Ably achieves a global mean latency of 37ms, with:<30msround trip latency within datacenter (99th percentile)<65msglobal round trip latency (99th percentile)
High availability
The platform is designed for:- 99.999% global service availability: Only 5 minutes 15 seconds of downtime per year
- 50% global capacity margin: For instant demand surges
- Automatic failover: Edge network failure resolution within 30 seconds
