SNS and SQS are both managed messaging services developed by AWS and supported by Scaleway Messaging. Although they are two separate services, they are often discussed simultaneously since they are frequently coupled to work together. A Scaleway Messaging SNS/SQS namespace supports both services simultaneously.
SNS (Simple Notification Service) was released in 2010. It enables users to interconnect their applications and systems using a publish/subscribe pattern. Many publishers can send messages to topics, while consumers, e.g. applications, can subscribe to topics to receive all (or a subset) of messages sent to this topic. Scaleway Messaging makes it easy to migrate your SNS-connected applications by providing a dedicated protocol gateway.
SQS (Simple Queue Service) became generally available in 2006. It is a highly scalable queuing service that facilitates the decoupling of software systems. Scaleway Messaging provides a gateway that enables you to connect your existing applications without having to significantly modify your code baseline.
Some SQS features are not yet supported. Refer to the developers documentation for more information.
Once you’ve created your namespace, the next step is to create credentials that give your applications permission to connect to the Scaleway Messaging service.
Credentials are scoped to the namespace (the bearer of the credentials can access this Messaging namespace only). You can choose to give each set of credentials the required level of permissions within the namespace:
- Read: receive messages from queues and topics.
- Write: send messages to queues and publish in topics.
- Manage: create or edit resources (such as queues and topics).
All further actions including creating, listing and managing queues and topics, sending messages etc. can be done using the AWS CLI or AWS SDKs. Check out our documentation to help you get started with the AWS CLI or AWS SDKs.
