Featured Reviews

PurbayanSaha - PeerSpot reviewer
Has API-led architecture and provides a unique, user-friendly, and scalable architecture for hosting APIs
There's room for improvement in multi-file transfer functionality. It's not convenient when using MuleSoft, and it should have better capability for handling large amounts of data. For example, applications like GoAnywhere can handle huge chunks of data, so the tool should also have something to facilitate that aspect of integration.
Ilir Lazaj - PeerSpot reviewer
Consolidated, reliable, and has responsive technical support
There is a minor need to improve the ease of configuration. The configuration of the product is not an easy task for everyone. I agree that it has to be that way, as it's a good technology, however, maybe for people with low experience it can be hard. There can be a higher learning curve. The setup can be difficult for those not familiar with the solution. I'd like to see the possibility of configuring the product via consoles with more elasticity without having the need to go to the single files in the file system, add the files manually, and then restarting. We'd like to make some changes, some tuning of the product, using the administration console. If this is extended to the console, it would be great. We need more operations done by the console. It simplifies the life of the worker.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The product offers a community edition that is free of cost."
"I'm not using ESB directly. It is the integration layer, so it's running under the hood. However, the conversion and transformation performance is excellent. Anypoint Enterprise Security is also solid."
"Once it is started, we don't see any problems on a day to day basis."
"The solution's drag-and-drop interface and data viewer helped us quite a lot."
"Easy connectivity and easy integration."
"The connectors help to connect with a variety of applications."
"The most valuable feature of Mule ESB is data transformation, i.e. our interacting with different systems and orchestrating for our business needs."
"For complex cases, we employ the SSLi engine, whereas for simpler ones like healthcare or response data, such as EDI 270 or 271. We prefer to use an external XRT engine instead of handling it within the ESB for ease of management."
"Currently, I find the configuration part quite valuable, where you can easily configure things."
"The solution basically conforms to our standards."
"The solution has two main parts: integration and transformation. It's very user-friendly and easy to understand for everyone."
"I like the user-friendly system and development of the service-oriented architecture."
"The stability is excellent."
"The drag-and-drop features for connectors are very valuable."
"The connectors have been the most impactful features for handling integrations. I can use these connectors when I need specific connectivity with a third party, like a core banking system in BFSI. I don't need to do all the development. I take the specific connector, put in the IP address and password, and it takes care of everything."
"In my opinion, the most valuable aspect of this solution is its extensive range of adaptors and connectors. This feature holds significant importance and provides great value to users."
 

Cons

"Improvements could be made in performance."
"In the next release, I would like to see improvement in the generator for the DataWeave language so that it's a little more graphic."
"Documentation is cryptic, product releases are far too frequent, and upgrades become troublesome."
"Mule ESB isn't as secure as IBM. Financial companies go with IBM for that reason."
"It would be great to see implementing security modules as a feature."
"From an improvement perspective, there should be fewer coding challenges for users in Mule ESB."
"We would like to have a built-in logging framework in which we can do auditing."
"The current version will not be supported for much longer."
"I would like to see better documentation for the open-source version."
"If I have to buy software, then it becomes expensive for me."
"The integration capabilities need to be improved."
"The customization can be a bit difficult."
"They should introduce better pricing for small companies."
"The micro integrator should be improved. There is room for enhancement considering alternative integration components."
"The setup can be difficult for those not familiar with the solution."
"I would like to see them bring back a feature, from earlier versions, that was very useful in debugging and finding issues."
 

Pricing and Cost Advice

"Mule ESB is an expensive solution."
"This product is expensive, but it does offer value for money."
"Mule ESB is a costly solution. We pay approximately $80,000 annually for the system. The cost of the number of instances, annual subscription, and cloud hosting services are expensive."
"This is expensive. In my next project, we had to go to other vendor."
"The licensing is yearly, and there are additional fees for services."
"The various features and components for this solution are no longer free."
"The pricing must be improved."
"The solution is expensive."
"The cost is better than IBM Cloud Pak."
"It is a low-cost solution."
"The pricing of WSO2 Enterprise Integrator for enterprise subscriptions can be considered expensive, especially from the perspective of someone who prefers open-source software."
"I rate the product price a six on a scale of one to ten, where one is low price and ten is high price."
"The open-source, unsupported version is available free of charge."
"The solution costs about 20,000 or 30,000 euros per year, per instance."
