Likelihood to Recommend If you need a cloud-based service bus or a simple to use queue/topic/routing/pub-sub service, then Azure Service Bus is a very good choice at a reasonable price and performance. Typically on-premise we'd use RabbitMQ because it "just works", but if you're building a "cloud-first" application, then this is the one to go with. It's especially easy to integrate with if you're already embedded in the Microsoft ecosystem.
Read full review JBoss Enterprise SOA Platform is great when you are looking at building more or less pure Java applications and SOA micro-services that may integrate with multiple external data sources. It is less useful when you are looking to build simple SOA applications that are simple in nature since the overhead associated with deploying as well as learning BPEL.
Read full review Pros Acting as a basic queuing service it works very well. One of the best parts is that Azure Service Bus can work over HTTPS which helps in strict firewall situations. There is a performance hit if you choose to use HTTPS. The routing capabilities are quite good when using topics and subscriptions. You can apply filters using a pseudo-SQL-like language though the correlation filters are quick and easy options. Costs are very reasonable at low-ish volumes. If you're processing 10's of millions of messages a month... it may be a different story. Read full review JBoss is open source so the cost overhead to deploy and build application is very low. JBoss Enterprise SOA Platform and its parent Redhat are reputed and well adapted in the industry so it is easy to find best practices documentation for complex deployments of JBoss middleware. Read full review Cons The SqlFilter could be a little easier to use, but it's not terrible. The performance while using HTTPS for the connection is a little slow compared to direct connections using AMQP ports. There is a size limit to the message - unlike RMQ for instance, Azure Service Bus caps messages to 256kb on the standard tier. Read full review JBoss Enterprise SOA Platform is dependent and build for JEE/Java application so using a different programming paradigm will be much harder. There is still a learning curve to get familiar with BPEL making it harder to get an SOA micro-service up and running compared to a fully cloud-based service Read full review Support Rating Redhat support generally is great and that is true for the JBoss Enterprise SOA Platform as well. Even if you do not buy support from Redhat, you can reply on the discussion board and bug fixes via the open-source JBoss without much trouble.
Read full review Alternatives Considered RabbitMQ is simple and awesome... but so is Azure Service Bus. Both accomplish the same thing but in different environments. If you're building a cloud-native application - especially one that is serverless by design - Azure Service Bus is the only real choice in Azure. It works well, it's performance, and it's reasonably priced in the Standard tier. From our testing, RMQ is more performant, but it's hard to compare service-based implementations vs RMQ installed on VMs.
Read full review Oracle SOA Suite (Oracle BPM +
Oracle BPEL + other components) and IBM WebSphere middleware is most costly and suited if you are already using applications and other middleware components from these vendors. Mulesoft (Salesforce
Mule ESB ) is best when you need deep integration with one of Salesforce's existing products. JBoss and
Apache Web Server are best when you do not want to invest infant CapEx/OpEx on license fee.
Apache Web Server based middleware is best for simple SOA applications.
Read full review Return on Investment Compared to open-source free software like RMQ, Azure Service Bus does have some costs to it. But the cost is reasonable. Also unlike RMQ, Azure Service Bus doesn't require you to stand up any hardware - so it's very easy to use and saves time/money from that perspective.

Positive ROI due to no license cost for JBoss Enterprise SOA. Read full review ScreenShots
