Srinivas-Kanduri

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.

It allows you to deal with any mediation situation based on messages using concepts like proxy services and APIs.

The Data Services Server is a beautiful product which allows you to "expose" your data as REST and/or SOAP services secured or not using any of the databases you might to keep your business data. Using with the Identity server it gives you the possibility to manage all the identity subjects in your Organization, it connects out of the box to any corporate user store you have through LDAP or JDBC, it allows you to manage different mechanisms to implement authentication / authorization using Web SSO, SAML2, OAUTH2, federated authentication, among others. Also, it allows you to control all this through its administrative interface which could be exposed out of the box as SOAP services and also you can use it to implement role based access controls using XACML policies and business claims.

Quotes from Members

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

Pros

"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."

"Mule Expression Language"

"Technical support is superb."

"There are many already defined endpoint components such as HTTP, JMS, FTP, etc., and these are the main tools for communicating with various services."

"This tool has exceptional API management and integration connectors in addition to multiple out of the box connectors."

"The scalability is amazing, and you can increase the horizontal perspective or increase the vertical perspective depending on your business needs."

"It has changed our approach towards integration, making plumbing functions such as HTTP/Messaging listener services, data transformation and connection handling redundant."

"Mule ESB is quite lightweight."

More Mule ESB pros

"The Enterprise Service Bus is really fast and flexible, it allows you to deal with any mediation situation based on messages using concepts like proxy services, APIs, and it has lots of connectors that facilitates its interaction with other products."

Cons

"It should have some amount of logging."

"There are limitations with the subscription model that comes with the product."

"We would like to have a built-in logging framework in which we can do auditing."

"Support, and with respect to licensing cost. Many of the customers feel that the licensing cost is much."

"The current version will not be supported for much longer."

"Documentation is cryptic, product releases are far too frequent, and upgrades become troublesome."

"In an upcoming release, I would like to see more additional concept for exception handling, batch processing, and increased integration with other application."

"MuleSoft is not so strong in method-based integration, so they're not so functional in that regard."

More Mule ESB cons

"In a general sense, the documentation of these products should be improved."

Pricing and Cost Advice

"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."

"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."

"Mule ESB is an expensive solution."

"Plan your licensing model (cloud or on-premises or hybrid) that will allow seamless integration with new partners."

"The pricing must be improved."

"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."
