Amazon MQ vs Amazon SNS: What are the differences?

Introduction

In this Markdown code, we will discuss the key differences between Amazon MQ and Amazon SNS. Both are messaging services provided by Amazon Web Services (AWS), but they have distinct features and functionalities that set them apart.

Message Types: Amazon MQ is a managed message broker service that supports multiple messaging protocols like AMQP, MQTT, STOMP, and OpenWire. It enables you to use both queue-based and topic-based message queues for point-to-point and publish-subscribe communication patterns. On the other hand, Amazon SNS is a fully-managed pub/sub messaging service that supports only simple messaging over various transport protocols like HTTP, HTTPS, email, SMS, and mobile push notifications. It facilitates the dissemination of messages to multiple recipients simultaneously.
Message Persistence: Amazon MQ provides durable message storage, meaning it can store messages when the recipient or subscriber is not available to receive them. It ensures the durability of messages even in the event of a broker failure. In contrast, Amazon SNS doesn't store messages persistently. It follows the "fire and forget" model, where messages are not stored and are only delivered to active subscribers at the time of publishing.
Message Ordering: Amazon MQ guarantees the ordering of messages within a single queue, maintaining the FIFO (First-In-First-Out) order. It ensures that the oldest message is consumed first before moving on to the next one. On the other hand, Amazon SNS doesn't guarantee message ordering. Messages published to SNS topics can be delivered to subscribers in any order, and they are not necessarily processed in the same sequence they were sent.
Message Filtering: Amazon MQ supports message filtering at the broker level, allowing subscribers to receive only specific messages based on defined criteria. It provides flexible filtering options using message selectors and header attributes. In contrast, Amazon SNS doesn't offer built-in message filtering capabilities. Subscribers of an SNS topic receive all the messages published to the topic, without the ability to filter based on message content.
Scaling: Amazon MQ enables automatic scaling of broker instances to handle increased message traffic. It automatically adjusts resources based on the workload to ensure optimal performance. On the other hand, Amazon SNS doesn't require scaling since it can handle high message volumes and traffic by design. It automatically provisions resources as needed to deliver messages.
Message Processing: Amazon MQ supports advanced features like message redelivery, dead-letter queues, and message acknowledgement, ensuring reliable message processing and handling. It provides mechanisms to handle failed message deliveries and handle messages that couldn't be processed successfully. In contrast, Amazon SNS doesn't offer these advanced message processing features. It focuses more on the publish-subscribe pattern without extensive handling of message errors or retries.

In Summary, Amazon MQ is a managed message broker service that supports multiple protocols, offers message persistence, ordering, filtering, scaling, and advanced message processing. On the other hand, Amazon SNS is a fully-managed pub/sub messaging service that supports simple messaging over various transport protocols and provides high scalability for message delivery but lacks some of the advanced features of Amazon MQ.

Amazon SNS	Amazon MQ
Amazon Simple Notification Service makes it simple and cost-effective to push to mobile devices such as iPhone, iPad, Android, Kindle Fire, and internet connected smart devices, as well as pushing to other distributed services. Besides pushing cloud notifications directly to mobile devices, SNS can also deliver notifications by SMS text message or email, to Simple Queue Service (SQS) queues, or to any HTTP endpoint.	Amazon MQ is a managed message broker service for Apache ActiveMQ that makes it easy to set up and operate message brokers in the cloud.
In most cases, developers can get started with Amazon SNS by using just three APIs: CreateTopic, Subscribe, and Publish. Additional APIs are available, which provide more advanced functionality.;With SNS you can publish a message once, and deliver it one or more times. So you can choose to direct unique messages to individual Apple, Google or Amazon devices, or broadcast deliveries to many mobile devices with a single publish request.;SNS allows you to group multiple recipients using topics. A topic is an “access point” for allowing recipients to dynamically subscribe for identical copies of the same notification. One topic can support deliveries to multiple endpoint types -- for example, you can group together iOS, Android and SMS recipients. When you publish once to a topic, SNS delivers appropriately formatted copies of your message to each subscriber.;Amazon SNS allows applications and end-users on different devices to receive notifications via Mobile Push notification (Apple, Google and Kindle Fire Devices), HTTP/HTTPS, Email/Email-JSON, SMS or Amazon Simple Queue Service (SQS) queues.;Amazon SNS provides access control mechanisms to ensure that topics and messages are secured against unauthorized access	-
