Messaging & Queuing

Easily connect services and enable asynchronous communication between microservices. Send messages and events without having to manage a message broker.

Enable smooth transitions between systems

Scaleway’s Messaging & Queuing supports various protocols (SNS, SQS, NATS) and is built on open-source components (NATS, Benthos). We support your multi-cloud strategy and make it easy for you to port your applications. Easily transition from other systems.

Create high-performance microservices

Fully managed message broker solution to help you easily create microservices-based applications, send asynchronous messages and events, and simplify application development, especially with Serverless.

Build scalable distributed applications

Achieve higher fault tolerance and resilience by enabling asynchronous service-to-service communication between microservices. Should a system’s service become unreachable, the other services can still continue to interact with the queue.

Popular use cases

Asynchronous communication

Enable async messaging for inter-service communication between microservices, decoupling them and buffering requests to allow independent tasks, making debugging, testing, and scaling easier.

Key features

Multi-protocol support

Based on open standards. Enable a multi-cloud approach to ease your microservice porting. Use AWS SQS, AWS SNS,or NATS API to send and receive messages or configure the queue.

Notifications (Publish Subscribe)

Distribute notifications and events across several consumers using a publish/subscribe pattern.

Queues and Streams Services

FIFO queues with deduplication enabling exactly-once messaging. We provide enhanced queue features such as Dead Letter Queue and Long Polling, and enable replay for messages stored in Stream using NATS JetStream.

Built-in Serverless integration

With the Scaleway Serverless integration, you can trigger Functions or Containers with events stored in SQS queues and NATS Stream.


With Restricted Access and encryption in transit, we ensure secure asynchronous communication between microservices.

Scalable & fully managed

An easy-to-use, fully managed infrastructure, a message broker solution that’s integrated into Scaleway’s console and tools (CLI, SDK, Terraform) to simplify application development, especially with Serverless.
