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

"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."

"This product is fairly out there in terms of usability and easy to use, such as you can implement and deploy."

"For us, we've basically outsourced the onboarding and translation of all of our electronic data interchange (EDI) with our customers."

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

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

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

"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."

More IBM Sterling B2B Integration Services pros

"It's open source, and there are a lot of community resources. Mule ESB makes it easy to connect to other software applications."

"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."

"Most of our use cases are for Salesforce. So, the connectors for Salesforce have been really helpful. They've made development two times faster."

"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."

"The product is very stable."

"The connectivity the solution provides is excellent. There are often too many systems that we have to integrate and this helps with that."

"Mule ESB is the heart of applications that require routing and improvement of messages such as electronic invoicing."

"The solution has a good graphical interface."

More Mule ESB pros

Cons

"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 setup is not straightforward, but it is fairly well documented."

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

"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."

"It's probably not as much as they sold us in their value proposition, so be cautious about that."

"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."

"From an improvement perspective, there should be fewer coding challenges for users in Mule ESB."

"Limitation on external subscribers to listen to the messages on the bus."

"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."

"The Anypoint platform consumes a lot of memory, and it would be great for developers if it were more lightweight."

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

"It is getting expensive and I recommend clients to use Camel ESB if enterprise support is not required."

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

More Mule ESB cons

Pricing and Cost Advice

"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 tool is expensive because of its rich features."

"This product is expensive, but it does offer value for money."

"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."

"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."

"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 pricing must be improved."

"The various features and components for this solution are no longer free."

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