The rapid adoption of cloud-based applications by the enterprise, combined with organizations’ desire to integrate applications with mobile technologies, is dramatically increasing application integration complexity. Oracle SOA Suite 12c, the latest version of the company's unified application integration and SOA solution, offers a simplified cloud, mobile, on-premises and Internet of Things (IoT) integration capabilities within a single platform.

RabbitMQ, an open source message broker, is part of Pivotal Software, a VMware company acquired in 2019, and supports message queue, multiple messaging protocols, and more.
RabbitMQ is available open source, however VMware also offers a range of commercial services for RabbitMQ; these are available as part of the Pivotal App Suite.
Oracle service bus is great to quickly proxy any legacy services exposed as soap service. It's well suited for aggregating multiple services on a single endpoint. We can point to multiple endpoints on the business service and use a round-robin approach to access the endpoints. It's not well suited for data transformation and quick preview of mappings and transformations. It's not great on path to cloud transformation.
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.
The Oracle Service Bus makes the management of web services extremely easy. Through its point and click interface, the web service endpoints can be easily modified.
The administration console provides useful dashboards to diagnose any service issues.
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.
Message reporting tied to a database seems counter productive. Better options to eliminate that would not only minimize the maintenance hassle but also gives more ease to manage the product.
Polling feature isn't very efficient where the end point JMS queues may still have JMS connections despite not enabling the corresponding poller proxy services.
Unable to deploy multiple web services in one go from the OSB Web console.
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.
We have had not many issues with Oracle Service Bus and it's very stable for our requirements. It's highly available and helps us implement Tier1 applications on it.
It's an excellent enterprise service bus and has very stable features. We have been using it since 2008. We did hit into some issues. But, recreating the service helped fix many issues. Also, deployment to various environments was easy. Also, the plugin on Eclipse helps to build proxy and business services quick and easy.
RabbitMQ is very usable if you are a programmer or DevOps engineer. You can setup and configure a messaging system without any programmatic knowledge either through an admin console plugin or through a command-line interface. It's very easy to spin up additional consumers when volume is heavy and it's very easy to manage those consumers either through automated scripting or through their admin console. Because it's language agnostic it integrates with any system supporting AMQP.
We had some issues with MQ connectivity through OSB and our experience was poor with the support team. They do respond. But, it felt like we are ignored and we had bad support. We had to escalate and things used to get dragged for weeks before we get more quality questions on how to pursue investigation.
RabbitMQ is more software than service so there's no real customer service to speak of unless you go with a provider such as CloudAMQP. So I'll just speak on CloudAMQP. Their customer support is only okay: they only do it over email. They frequently gloss over our support tickets and half answer them without delving deeply or investigating our issues. Their response times are pretty reasonable though.
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
Earlier we had a problem with missing work items with our own implementation but later using RabbitMQ is solved a problem. Now our job processing mechanism is highly reliable.
We also had a problem with scaling, processing 1k work items per second. RabbitMQ helped us to scale well with increasing work items.
