Featured Reviews

MANUEL VALDIVIA - PeerSpot reviewer
Senior Manager at a financial services firm with 1,001-5,000 employees
Routes messages efficiently across our services, but the features for scalability need improvement
One of the key benefits has been its ability to expose services and securely integrate applications within our architecture. It's been integral in maintaining a stable infrastructure despite its limitations with dynamic service creation and flexibility compared to newer technologies like Kubernetes. The main challenge has been scalability during peak usage times.
Srinivas-Kanduri - PeerSpot reviewer
Enterprise integrator at a tech vendor with 10,001+ employees
Integration architecture has enabled reliable multi-channel messaging and secure API management but now needs better analytics and simpler development
In my opinion, the real-time analytics part of Mule ESB is not up to the mark for the decision-making process. While there are some analytics features, they lack the standards needed for enterprise use. Compared to other analytics tools such as Power BI, MuleSoft falls short.Points for improvement in Mule ESB definitely include enhancing the analytics capabilities because currently, they rely on external logging tools such as Splunk or ELK, which is lagging behind compared to other tools such as Workato that offer more analytical features. Additionally, issues arise with AI-based use cases due to dependencies on Salesforce tools such as agent force, making development more complicated when it should be more independent. Developing AI-based agents without being tied to Salesforce applications could also enhance functionality.

Quotes from Members

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

Pros

"Before the cloud, it was very easy for us to build and it was quick to integrate."
"It has many interfaces and you can connect to any backend source that has another format, and convert it to the desired format."
"Integration and mapping are easy, which is a major advantage."
"We have a large number of use cases for this product, and it is built into the underlying infrastructure for most of our applications."
"The solution has good integration."
"Straightforward development and deployment."
"It's reliable for our day-to-day operations, ensuring fast and secure data integration across different systems."
"The documentation, performance, stability and scalability of the tool are valuable."
"There are many already defined endpoint components such as HTTP, JMS, FTP, etc., and these are the main tools for communicating with various services."
"Mule ESB has a user-friendly design, and everything is in one place. The API and architecture are popular right now. Also, MuleSoft has a large and supportive online community."
"I like that Mule ESB provides fast and good technical support."
"We can use Java expressions anywhere in the flow."
"Mule ESB is the heart of applications that require routing and improvement of messages such as electronic invoicing."
"It is the best integration platform for those who are looking to implement or are going for API-based architecture and microservices-based architecture."
"The solution offers multiple deployment options."
"The most powerful feature is DataWeave, which is a powerful language where data can be transformed from one form into another."
 

Cons

"It is currently a weighty product."
"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."
"Technical support is very slow and needs to be improved."
"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."
"I know that Message Broker was a very tightly copied product with another IBM product, that is, IBM MQ. I would like to have a little bit more decoupling from the IBM MQ because it should not be a prerequisite for IBM WebSphere Message Broker usage."
"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."
"My biggest complaint about this product is the price."
"Technical support is good but they could have a better response time."
"I think there are some connectors that are not available that should be included."
"There are some features on the commercial version of the solution that would be great if they were on the community version. Additionally, if they added more authorization features it would be helpful."
"From my perspective, Mule ESB is lightweight, but it can be improved when it comes to the agility of the system."
"In India, particularly in the banking sector, clients do not prefer cloud solutions due to regulatory and compliance requirements."
"In respect of the UI or the interface, a concept such as that offered by Microgateway would be preferable."
"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."
"Mule ESB is more into the latest REST APIs, not much into the SOAP web services. Developing is all about web services and not easy with Mule."
"It needs more samples. Also, the dependency on Maven should be removed."
 

Pricing and Cost Advice

"IBM products are generally more stable and have more features, but also come at a greater cost."
"The licensing cost of IBM WebSphere Message Broker needs to be reduced"
"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."
"I feel with IBM, when you want certain functions or features, you have to continuously purchase add-ons. There are always additional fees."
"The solution is expensive."
"The solution is expensive."
"The price is very high and it's the main reason that we are searching for alternatives."
"This product is more expensive than competing products."
"The solution is expensive."
"Mule ESB is an expensive solution."
"This product is expensive, but it does offer value for money."
"This is expensive. In my next project, we had to go to other vendor."
"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."
"I think the price is very high. If you use TIBCO BW, the license is for the CPU usage, then the IPS, and support. I also think the license for the product is a one-time expense."
"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."
"The various features and components for this solution are no longer free."
