Lightweight and efficient solution
It's very good and lightweight. But, it does not provide web service communication. But it is excellent for internal connections One valuable feature is the messaging broker. If there is a disruption, it restores the messages. And when the application is running, it delivers all the messages. The…

Transforms enterprise integration with comprehensive platform and excellent support
The best features of this solution are that everything we get into a single platform, whether it's integration, API, or data modeling; everything is available in one platform. It's a hybrid, including cloud and on-premise solutions with good connectivity and good connectors. From the benefits of using Mule ESB, we could reduce the manual tasks to 50% in one to two years. The cost is still something we are trying to make lower because we see some advantages when we move from point-to-point integration to API-led connectivity. We have seen a lot of reusable assets, so the cost is reduced. Ultimately, we want to see how it's transformed into business revenue; that's what we are still looking into.

Decreases the development timeframe and costs
The main issue with the product is pricing. It uses core-based pricing for WSO2 Enterprise Integrator and API Manager. It would be best if you had APIM by default. It provides many connectors for easy integration with third-party systems. Often, customers decide to develop using open-source tools like Spring Boot if there aren't many connectors required to avoid increasing costs. They'll develop this way and then deploy using APIM, the bare minimum needed. It is mainly required for very complicated setups with many connectors. In the implementations I've seen, people often used open-source tools because there weren't many third-party systems involved—just their organization's own systems. From WSO2 Enterprise Integrator, I expect them to bring up more and more connectors in the future. That's the main expectation. Having more connectors in various areas will help us when discussing new requirements. I don't have any specific use case right now, so I can't name a particular connector. But, as new technologies emerge, the relevant connectors should be there for those. WSO2 Enterprise Integrator mainly helps with the integration part, which can be simplified only if you have relevant connectors for whatever you're doing.

Quotes from Members

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

Pros

"SDM: User-friendly tool which allows for a seamless approach to performing hotfixes, if required."
"The solution is highly scalable, this is very important for us. It can handle a lot of messages."
"The features that I have found most valuable are that it is very easy to develop. Most of it is graphical, but we also have the option to add any custom call that you need."
"ESB: Provides all kind of possibilities to resolve business needs. A lot of ready to use services plus custom Java services. I used a lot of them all."
"The solution offers excellent stability."
"The Messenger Broker is a really good feature."
"The solution doesn't require much code writing and we can develop APIs very easily."
"It is one of the best integration tools in the market."
"The connectors help to connect with a variety of applications."
"The most valuable features of Mule ESB are its ease of use, documentation, ease to adapt to newer security and vulnerabilities, and a lot of help available. Additionally, there is a lot of flexibility, many patches available, and they provide APIs. They are a market standard."
"The solution's drag-and-drop interface and data viewer helped us quite a lot."
"It was pretty fast to develop APIs on this platform, which is something I liked about it. So, the time to value was pretty good."
"The solution improved my company by modernizing the way we offer services and improving the user experience."
"The most powerful feature is DataWeave, which is a powerful language where data can be transformed from one form into another."
"The learning curve for this solution is very good."
"The solution's customer service is good."
"It was mostly easy to set up the product."
"The installation process is easy."
"It's a very complete product. It allows us to network security and add more layers of security to the system."
"The solution basically conforms to our standards."
"It's a consolidated product. It works and it does its job pretty well."
"The customer service executives are very responsive."
 

Cons

"I don't know if the last version has the cloud option, but maybe that could be good. That could be something that is included."
"The solution needs to improve support for new, more recent protocols on the API."
"It should include/add more services with the product as per market demand. It should include custom Java services developed by any organization or provide a platform where users/developers can share ideas/custom services, etc."
"You should not hurry with upgrades without testing the whole product completely."
"The improvement is that it should be on the cloud and use web services."
"Aurea CX Messenger could improve by making better use of the new APIs"
"I cannot say that installation with Kubernetes needs to be improved to be less tricky, but more information is needed from MuleSoft. They do not help much with Kubernetes, so we should have a person who is well-versed in Kubernetes to handle this."
"It would be much more beneficial if the solution included AI and business process management."
"From my perspective, Mule ESB is lightweight, but it can be improved when it comes to the agility of the system."
"The solution isn't as stable as we'd like it to be. There are some ongoing issues and therefore Mule has to provide frequent patches. Mule's core IP should be more stable overall."
"It's not easy to troubleshoot and we still can't make it work."
"It should have some amount of logging."
"In order to meet the new trend of active metadata management, we need intelligent APIs that can retrieve new data designs and trigger actions over new findings without human intervention."
"Limitation on external subscribers to listen to the messages on the bus."
"If I have to buy software, then it becomes expensive for me."
"I would like to see them bring back a feature, from earlier versions, that was very useful in debugging and finding issues."
"The integration capabilities need to be improved."
"One of the reasons that we are looking for a replacement is their way of defining integration. The language of the XML structures that I use to describe the integrations are not that standard, and it's not easy to find people who are familiar with this approach."
"The administration side is complex and could use significant improvements to enhance the solution's functionality."
"The customization can be a bit difficult."
"They should introduce better pricing for small companies."
"The setup can be difficult for those not familiar with the solution."
 

Pricing and Cost Advice

"The pricing is not so high."
"Much better than Oracle SOA Suite."
"You pay nothing for licensing, because the commercial model is a subscription. Other environments, such as QA and Development, are included in the subscription"
"Regarding licensing and pricing, I find it somewhat flexible. They are more flexible with larger customers compared to small and medium ones, as their licensing model depends on ports and other factors. Large customers benefit from more flexibility in implementation and renewal compared to smaller ones."
"You will not get any support from Mule ESB's team for the tool's community edition...You can get support with the licensed version of Mule ESB."
"The licensing is yearly, and there are additional fees for services."
"This product is expensive, but it does offer value for money."
"The various features and components for this solution are no longer free."
"This is expensive. In my next project, we had to go to other vendor."
"This product is cheaper than some offered by other vendors, although there is a problem because you have to pay for some third-party adapters."
"Most of the challenges that I had with this solution were for smaller customers. There is not a good licensing model or pricing model. It is more expensive than other solutions, and that's the downside of MuleSoft. I had to be creative to be able to sell it to the business, but we did. This is something they have to work on because for large companies, it's affordable, but for small and medium businesses, it's very hard to sell."
"The pricing of WSO2 Enterprise Integrator for enterprise subscriptions can be considered expensive, especially from the perspective of someone who prefers open-source software."
"The solution costs about 20,000 or 30,000 euros per year, per instance."
"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 cost is better than IBM Cloud Pak."
"It is a low-cost solution."
"The open-source, unsupported version is available free of charge."
