Amazon SQS vs Azure Service Bus: What are the differences?
Amazon SQS: Fully managed message queuing service. Transmit any volume of data, at any level of throughput, without losing messages or requiring other services to be always available. With SQS, you can offload the administrative burden of operating and scaling a highly available messaging cluster, while paying a low price for only what you use; Azure Service Bus: *Reliable cloud messaging as a service (MaaS) *. It is a cloud messaging system for connecting apps and devices across public and private clouds. You can depend on it when you need highly-reliable cloud messaging service between applications and services, even when one or more is offline.
Amazon SQS and Azure Service Bus can be primarily classified as "Message Queue" tools.
According to the StackShare community, Amazon SQS has a broader approval, being mentioned in 497 company stacks & 402 developers stacks; compared to Azure Service Bus, which is listed in 11 company stacks and 8 developer stacks.
Hello dear developers, our company is starting a new project for a new Web App, and we are currently designing the Architecture (we will be using .NET Core). We want to embark on something new, so we are thinking about migrating from a monolithic perspective to a microservices perspective. We wish to containerize those microservices and make them independent from each other. Is it the best way for microservices to communicate with each other via ESB, or is there a new way of doing this? Maybe complementing with an API Gateway? Can you recommend something else different than the two tools I provided?
We want something good for Cost/Benefit; performance should be high too (but not the primary constraint).
Thank you very much in advance :)
There are many different messaging frameworks available for IPC use. It's not really a question of how "new" the technology is, but what you need it to do. Azure Service Bus can be a great service to use, but it can also take a lot of effort to administrate and maintain that can make it costly to use unless you need the more advanced features it offers for routing, sequencing, delivery, etc. I would recommend checking out this link to get a basic idea of different messaging architectures. These only cover Azure services, but there are many other solutions that use similar architectural models.

I want to schedule a message. Amazon SQS provides a delay of 15 minutes, but I want it in some hours.
Example: Let's say a Message1 is consumed by a consumer A but somehow it failed inside the consumer. I would want to put it in a queue and retry after 4hrs. Can I do this in Amazon MQ? I have seen in some Amazon MQ videos saying scheduling messages can be done. But, I'm not sure how.

Mithiridi, I believe you are talking about two different things. 1. If you need to process messages with delays of more 15m or at specific times, it's not a good idea to use queues, independently of tool SQM, Rabbit or Amazon MQ. you should considerer another approach using a scheduled job. 2. For dead queues and policy retries RabbitMQ, for example, doesn't support your use case. https://medium.com/@kiennguyen88/rabbitmq-delay-retry-schedule-with-dead-letter-exchange-31fb25a440fc I'm not sure if that is possible SNS/SQS support, they have a maximum delay for delivery (maxDelayTarget) in seconds but it's not clear the number. You can check this out: https://docs.aws.amazon.com/sns/latest/dg/sns-message-delivery-retries.html
