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

"Integration and mapping are easy, which is a major advantage."
"This is a very reliable and stable solution that is used for a very large number of transactions."
"It has many interfaces and you can connect to any backend source that has another format, and convert it to the desired format."
"The documentation, performance, stability and scalability of the tool are valuable."
"The solution has good integration."
"Overall, in comparison to other solutions specific to the banking domain, this product is quite good."
"It's reliable for our day-to-day operations, ensuring fast and secure data integration across different systems."
"We are using three or four services in the backend for reformatting messages, and it is straightforward to use."
"Everything runs in Java, which is a useful feature."
"The solution improved the company by modernizing the way they offer services and improving the user experience."
"The most valuable feature of Mule ESB is data transformation, i.e. our interacting with different systems and orchestrating for our business needs."
"We can use Java expressions anywhere in the flow."
"We can do very fast development of the orchestrations of MuleSoft."
"The product offers a community edition that is free of cost."
"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."
"I am impressed with the product's connectors and scalability."
 

Cons

"It is currently a weighty product."
"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."
"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."
"Stability and pricing are areas with shortcomings that need improvement."
"The solution can add container engines such as docker."
"The images and size of the containers are too big and I think that they should be more lightweight."
"Technical support is good but they could have a better response time."
"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."
"The initial setup could be more straightforward."
"Mule ESB is a costly solution."
"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."
"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."
"It's not easy to troubleshoot and we still can't make it work."
"In India, particularly in the banking sector, clients do not prefer cloud solutions due to regulatory and compliance requirements."
"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."
 

Pricing and Cost Advice

"IBM products are generally more stable and have more features, but also come at a greater cost."
"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 licensing cost of IBM WebSphere Message Broker needs to be reduced"
"The price is very high and it's the main reason that we are searching for alternatives."
"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."
"The solution is expensive."
"This product is more expensive than competing products."
"The solution is expensive."
"Mule ESB is an expensive solution."
"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 pricing must be improved."
"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 product is expensive, but it does offer value for money."
"The licensing is yearly, and there are additional fees for services."
"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."
