RabbitMQ vs. SAP NetWeaver BPM

It is highly recommended that if you have microservices architecture and if you want to solve 2 phase commit issue, you should use RabbitMQ for communication between microservices. It is a quick and reliable mode of communication between microservices. It is also helpful if you want to implement a job and worker mechanism. You can push the jobs into RabbitMQ and that will be sent to the consumer. It is highly reliable so you won't miss any jobs and you can also implement a retry of jobs with the dead letter queue feature. It will be also helpful in time-consuming API. You can put time-consuming items into a queue so they will be processed later and your API will be quick.

It is well suited when we need to integrate business processes with SAP ERP and SAP CRM - the solution can be integrated with business rules/procedures defined in SAP ERP/CRM and NetWeaver can be used to monitor the rules and flag off exceptions. When there are multiple workflows running, it tends to slow down running of these processes. Also, it entirely depends on SAP portal for it to run efficiently.

• What RabbitMQ does well is what it's advertised to do. It is good at providing lots of high volume, high availability queue. We've seen it handle upwards of 10 million messages in its queues, spread out over 200 queues before its publish/consume rates dipped. So yeah, it can definitely handle a lot of messages and a lot of queues. Depending on the size of the machine RabbitMQ is running on, I'm sure it can handle more.
• Decent number of plugins! Want a plugin that gives you an interface to view all the queues and see their publish/consume rates? Yes, there's one for that. Want a plugin to "shovel" messages from one queue to another in an emergency? Check. Want a plugin that does extra logging for all the messages received? Got you covered!
• Lots of configuration possibilities. We've tuned over 100 settings over the past year to get the performance and reliability just right. This could be a downside though--it's pretty confusing and some settings were hard to understand.

• Virtual paper trail. Iterations of process and current documentation are all stored as "artifacts", leaving a great trail.
• Configuration of users. BPM somewhat magically determines which users will be impacted and automates rules.
• A pro (that is also a con) is the design interface. If you know what you are doing, it is incredibly powerful and malleable.

• It breaks communication if we don't acknowledge early. In some cases our work items are time consuming that will take a time and in that scenario we are getting errors that RabbitMQ broke the channel. It will be good if RabbitMQ provides two acknowledgements, one is for that it has been received at client side and second ack is client is completed the processing part.

• Live readings would be nice.
• Easier to maneuver
• Work with all systems with the press of one keystroke

As a big fan of SAP in general, the BPM solution fits right in with all the other things SAP does well, and does it with incredible efficiency

RabbitMQ is very easy to configure for all supported languages (Python, Java, etc.). I have personally used it on Raspberry Pi devices via a Flask Python API as well as in Java applications. I was able to learn it quickly and now have full mastery of it. I highly recommend it for any IoT project.

I gave it a 10 but we do not have a support contract with any company for RabbitMQ so there is no official support in that regard. However, there is a community and questions asked on StackOverflow or any other major question and answer site will usually get a response.

We have our own tech support for systems, I would say they probably could use more training on it, I don't really think it's anything regarding the SAP system, but more the knowledge they have on the system itself. It seems to take longer for them to fix any issues we may come across.

RabbitMQ has a few advantages over Azure Service Bus 1) RMQ handles substantially larger files - ASB tops out at 100MB, we use RabbitMQfor files over 200MB 2) RabbitMQ can be easily setup on prem - Azure Service Bus is cloud only 3) RabbitMQ exchanges are easier to configure over ASB subscriptions ASB has a few advantages too 1) Cloud based - just a few mouse clicks and you're up and running

I found the initial setup of NetWeaver is much simpler than other products especially in an SAP environment where we have SAP ERP/HRM/CRM as it can be well integrated with other SAP products. The only drawback is the need/dependency on SAP Portal. It is better suited in an environment where SAP ERP is running.

• Positive: we don't need to keep way too many backend machines around to deal with bursts because RabbitMQ can absorb and buffer bursts long enough to let an understaffed set of backend services to catch up on processing. Hard to put a number to it but we probably save $5k a month having fewer machines around.
• Negative: we've got many angry customers due to queues suddenly disappearing and dropping our messages when we try to publish to them afterward. Ideally, RabbitMQ should warn the user when queues expire due to inactivity but it doesn't, and due to our own bugs we've lost a lot of customer data as a result.
• Positive: makes decoupling the web and API services from the deeper backend services easier by providing queues as an interface. This allowed us to split up our teams and have them develop independently of each other, speeding up software development.

• Helped us harness integrated benefit from having SAP ERP/CRM by leveraging NetWeaver to define business processes/rules and monitor exceptions
• Did not have any negative experience except for the fact that at times when multiple rules run, it can be somewhat slow
