What is the AWS Equivalent of Azure Service Bus?
AWS offers a combination of AWS SQS, SNS & EventBridge as an AWS equivalent to Azure Service Bus. These services work together to provide the same features as Azure Service Bus. In addition, AWS offers managed RabbitMQ & Kafka services if an application prefers an open-source solution.
Comparing Azure Service Bus vs. AWS Messaging Services
Azure Service Bus is a messaging service that enables communication between applications and services. It is a vital component for building scalable and reliable distributed systems. In AWS, several services provide similar functionality to Service Bus, such as Amazon Simple Queue Service (SQS), EventBridge, and Amazon Simple Notification Service (SNS).
AWS Simple Queue Service (SQS) is a fully managed message queuing service that enables decoupling components in a distributed system. It allows different components to communicate asynchronously, reducing their coupling.
AWS Simple Notification Service (SNS) is a publish/subscribe messaging service that enables fan-out communication between components. It enables a single message to be sent to multiple subscribers, which is useful in scenarios where multiple components must be notified of an event.
Amazon EventBridge is a serverless event bus service that facilitates the building and managing event-driven architectures and applications. It extends the power of events by making it easy to ingest, filter, transform, and deliver events from various sources to different AWS services and on-premises applications.
| Feature | AWS SQS (Simple Queue Service) | AWS SNS (Simple Notification Service) | Azure Service Bus | Amazon EventBridge |
|---|---|---|---|---|
| Message delivery | Pull model | Push model | Push & Pull model | Push model |
| Persistence | Yes | No | Yes | Yes |
| Message ordering | FIFO queues provide strict ordering | No strict ordering | Yes | No |
| Delivery Guarantee | At least once | At least once | At least once | At least once |

What is Azure Service Bus
Azure Service Bus is a messaging service that enables communication between different applications and services. It provides a reliable and scalable platform for asynchronous communication, which is critical for building distributed systems. Service Bus supports various messaging patterns, including publish/subscribe, request/response, and message queuing.
In Service Bus, messages are sent and received using queues or topics. Queues are used for point-to-point communication, sending a message to a single receiver. Conversely, topics are used for publish/subscribe communication, where a message is sent to multiple subscribers.
Service Bus provides several features to ensure reliable message delivery, including message retries, dead-letter queues, and message expiration. It also supports message ordering and session communication, where a sequence of messages is processed in a specific order.
In addition to messaging, Service Bus also provides Relay, which enables hybrid connectivity between on-premises and cloud-based services. Relay allows external clients to securely access internal services without opening inbound ports or managing firewall rules.
Azure Service Bus is a powerful messaging service that provides reliable and scalable communication between applications and services.
Amazon Web Services (AWS)
Amazon Web Services (AWS) is a cloud-based platform that provides a wide range of services for building and deploying applications. It offers various messaging services that we can use for different scenarios.
One of the messaging services provided by AWS is Amazon Simple Queue Service (SQS), which is a fully managed message queuing service. It enables the decoupling of components and distributed application systems.
Another messaging service is Amazon Simple Notification Service (SNS), a fully managed pub/sub messaging service that enables sending and receiving messages between distributed systems.
AWS also provides Amazon MQ, a managed message broker service that supports multiple messaging protocols such as AMQP, STOMP, and MQTT. It enables the migration of existing messaging workloads to the cloud with minimal code changes.
In addition, AWS offers Amazon Kinesis, a platform for streaming data on AWS. It enables real-time streaming data collection, processing, and analysis. We can use it for various scenarios, such as real-time analytics, data processing, and machine learning.
AWS provides a range of messaging services that we can use for different scenarios. Developers can choose the service that best fits their use case and requirements.
AWS Equivalent to Azure Service Bus
AWS offers various services that can be equivalent to Azure’s Service Bus.

Comparison Between SQS and SNS
Amazon Web Services (AWS) offers two messaging services that are commonly used for building distributed applications: Amazon Simple Queue Service (SQS) and Amazon Simple Notification Service (SNS). Both services are designed to decouple application components and improve scalability, reliability, and performance.
However, some key differences between the two services are worth considering.
SQS
Amazon SQS is a fully managed message queuing service that enables applications to communicate asynchronously by sending and receiving messages. It offers a reliable, highly scalable, and flexible messaging system that can handle any message volume without requiring additional infrastructure. Some of the key features of SQS include:
- Supports both standard and FIFO (first-in, first-out) queues
- Provides at-least-once delivery of messages
- Offers server-side encryption of messages
- Enables message filtering and redelivery
- Supports long-polling and short-polling
SNS
Amazon SNS is a fully managed pub/sub-messaging service that enables applications to send messages to multiple recipients or subscribers. It offers a highly available, durable, and flexible messaging system that can be used for various use cases, such as push notifications, SMS messaging, email notifications, and more. Some of the key features of SNS include:
- Supports multiple protocols, such as HTTP, HTTPS, email, SMS, and mobile push notifications
- Provides fan-out messaging, which enables messages to be sent to multiple subscribers simultaneously
- Offers message filtering and subscription filtering
- Enables message delivery retries and dead-letter queues
- Supports message encryption in transit and at rest
Comparison
Here are some of the key differences between SQS and SNS:
| Feature | SQS | SNS |
| Message Delivery | At-least-once | At-least-once |
| Message Type | Point-to-point | Publish/subscribe |
| Message Protocol | HTTP/HTTPS | Multiple protocols |
| Message Destination | Queue | Topic |
| Message Filtering | Yes | Yes |
| Message Encryption | Yes (server-side) | Yes (in transit and at rest) |
| Message Retry | Yes | Yes |
| Dead-Letter Queue | Yes | Yes |
| Fan-Out Messaging | No | Yes |
SQS and SNS are powerful messaging services that can help improve distributed applications’ scalability, reliability, and performance. SQS is best suited for point-to-point messaging scenarios, where messages are sent to a specific queue and processed by a single consumer. On the other hand, SNS is best suited for pub/sub messaging scenarios, where messages are sent to a topic and delivered to multiple subscribers.

Service Bus Equivalent in AWS: Exploring Messaging and Eventing Services Summary
AWS provides several messaging options and queuing services equivalent to Azure’s Service Bus although there isn’t a single one-to-one match. Combining Simple Queue Service (SQS), Simple Notification Service (SNS), & EventBridge together are the most common services that provide the equivalent functions as Azure Service Bus. Amazon Simple Queue Service (SQS) is the most commonly used service, which provides a highly scalable and reliable messaging service. Amazon Simple Notification Service (SNS) is another option that provides a pub/sub messaging model.
One key difference between Azure Service Bus and AWS messaging services is the support for message ordering. While Azure Service Bus supports message ordering, AWS messaging services do not guarantee message ordering. This can be a consideration when choosing a messaging service for certain applications.
Another difference is the pricing model. Azure Service Bus charges based on the number of operations performed, while AWS messaging services charge based on the number of messages processed. This can significantly affect the cost for applications that perform many operations per message.
Azure Service Bus and AWS messaging services provide reliable and scalable messaging and queuing services. The choice between the two will depend on the specific needs and requirements of the application.
