InterSystems Ensemble (legacy product) vs. WSO2 Enterprise Service Bus

• Best suited for fast development with a fundamental emphasis on object orientation
• Prohibitive costs for very small integration projects

WSO2 ESB is an awesome product for companies looking to venture into the world of SOA with an ESB. They have a lot of other products too that can work really well with their carbon infrastructure. The interface is simple for deploying and managing proxy services. You can also write custom modules within the ESB using Java with IDE like Eclipse

• Easy to use: The simplicity of its programming language allows fast learning. Visual environment to generate complex code.
• Robust: A fall of the system will not be a problem. Never again will information of the transactions in progress be lost. Never more messages lost.
• Connect to the world: The most popular connection is possible to implement quickly. FTP, File folder, TCP, SMPT, REST.... all method are ready to use. Only define "where" and "how"

• One of the basic requirement of an ESB product is that it should be able to support transformation. WSO2 ESB provides support of XSLT, so you can transform your request to whatever format. Moreover, transformations like converting your xml payload into JSON and JSON payload to XML are out of the box available.
• WSO2 ESB provides a scheduler feature, by which you can configure your own scheduler to call a proxy service at a particular time of day or or initiate sequence.
• WSO2 ESB provides excellent error handling techniques, WSO2 ESB provides detailed error handling scenarios to tackle all the situations. WSO2 ESB also provides custom error handling by which you can make your own custom error message before sending it back to client.

• Given that Ensemble and Cache are one of if not the only true fully object orientated database/development technologies for massive transactional data systems its customizability is extensive and it just comes down to the creativity of the developer to get the products to pretty much do whatever they want to do with it. However, this is not necessarily obvious to newcomers to the technology.
• The developer community could do with greater participation from the software developers/application specialists and engineers within InterSystems.
• More extensive documentation and greater access to proven working solutions particularly in the realm of some of the lesser known or new and upcoming technologies.

• While it's easy to configure for a quick start, it is not so easy to deploy by yourself in a complex production scenario.
• Not very stable for production usage, we encountered several trivial bugs that make us believe that this product is still not widely adopted.
• Lack of a built in mechanism for auto-restart in case of an application server crash.

Compared to competitors the overall experience has been fine

Lack of auto-restart built-in capabilities. In case of running out of memory there are no built-in methods to recover from a crash, just for example, Oracle WebLogic Node Manager.

The product is performing well and consuming few resources

I have yet to raise an issue with InterSystems WRC that they have been unable to resolve to my satisfaction in the 20+ years that I have worked with their products.

Our experience with the WSO2 support has beent satisfactory

Mirth is another integration platform that we have used but its development, in Java, made us always create new methods every time a new product was integrated. Every connection process had to be developed from the beginning and it was not easy to reuse code. Nor did it allow us to have an extensive catalog of HL7 messaging, having to perform the validation of each and every one of its fields manually.

It's the only one truly open source and free.

Adding a server node is really straightforward, there are just few point in the configuration files.

• We have integrated 5 laboratories in a treatment monitoring system in less than a month of development. Being able to integrate the following in a period no longer than a week.

• Very well documented tutorials and case studies makes it easy to learn.
• It has a really supportive community
• It is fast and it can easily handle 300 tps of average use on a VM with 4Gig RAM
