Ravikumar Tanvee

Seeburger Lead EDI Developer/Analyst at a tech vendor with 10,001+ employees

Effective business process handling with some room for improvement in mapping ease and user interactions

IBM Sterling B2B Integration Services does not have specific issues that need improvement. While each product, like SeeBurger and IBM Sterling B2B Integration Services, has its own advantages and disadvantages, I do not see any challenges or improvements needed. Although, mapping might be a bit easier in SeeBurger compared to IBM Sterling B2B Integration Services.

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.

Quotes from Members

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

Pros

"IBM Sterling B2B Integration Services is a stable and scalable product."

"The product's most valuable feature is the real-time integration suite."

"We are able to monitor all B2B messages, and we are able to see or track each message on it from an error perspective. That's a good side of it. It is working well, and we're able to do our current job."

"They have best-in-class, quality support."

"The solution is extremely scalable."

"They have multiple features for each kind of task and issue. The company has different channels to give information to the administration. Security and integration capabilities are also important. This product has helped to replace a lot of other solutions, saving time and cost."

"Everything runs in Java, which is a useful feature."

"The solution's drag-and-drop interface and data viewer helped us quite a lot."

"The transformation and the data format are the features that I like the most."

"The product offers a community edition that is free of cost."

"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."

"The most valuable feature of Mule ESB is data transformation, i.e. our interacting with different systems and orchestrating for our business needs."

"The solution offers multiple deployment options."

"It is easily deployable and manageable. It has microservices-based architecture, which means that you can deploy the solution based on your needs, and you can manage the solution very easily."

More Mule ESB pros

Cons

"Onboarding on the solution is complex. It's hard to onboard partners and customer suppliers. It's one aspect that is not that straightforward."

"It can be now classified as a legacy system because there are no more updates. From what I know, there will be no updates for the current version, which is an issue. Therefore, we are looking for a compatible new software that we can use. We're currently researching what is there in the market. We would consider something that would give us better speed on our current processor. There is also room for improvement in terms of its scalability and GUI. It is an old system, and its scalability can be improved. Its GUI can also be more appealing."

"They can improve APIs because they are still lagging behind in API connectivity. With non-API connectivity, they're market leaders, but API connectivity, they're still in the immature space."

"The only weaknesses they have different governance for each task and different channels for communication which are hard to maintain. The relation of the company with other companies can be improved. We have a lot of customers who this platform for the interchange of information which can also be improved. The compliance information about banks can also be updated."

"The price of Mule ESB could improve."

"Community editions need more attention."

"In India, particularly in the banking sector, clients do not prefer cloud solutions due to regulatory and compliance requirements."

"One area that could be improved is the way that policies are propagated when APIs are moved from one environment to another. It's an issue, but when you develop and test the rest APIs in a lower environment and need to move them, there's a propagation process. This process moves certain aspects of the APIs, like the basic features. But when we move them, the policies don't always move with them. The policies should be able to move so we don't have to redo them manually. There are some APIs we use, but it's a bit tedious."

"I would like to see support for BPM in the next release of this solution."

"There are some issues with both stability and scalability."

"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."

"The payment system needs improvement."

Pricing and Cost Advice

"The tool is expensive because of its rich features."

"Pricing is a little bit on the higher side because they give you the best support. Out of ten, I would rate pricing at seven or eight."

"They have a good pricing system, in relation to powerful features."

"The pricing must be improved."

"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."

"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."

"This is expensive. In my next project, we had to go to other vendor."

"Mule ESB is an expensive solution."

"The solution is expensive."

"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."

"The price of the Mule ESB commercial version is expensive. However, they have a free community version."
