General Manager Neverhack Spain at a tech vendor with 11-50 employees

Experience with robust integrator reveals strong performance and potential for interface updates

Based on my experience and my clients' feedback, there are a few points IBM can improve for IBM B2B Integrator. One of these is the graphical user interface. For several years, IBM has been promising to renew this interface, which has an ancient, old aesthetic, though it contains many functionalities. Creating a new interface would incur a very high internal cost with no new profitability for IBM. This is one of the points where customers say it feels like working in the 1990s with this interface. Another significant issue is that the platform is not multi-tenant. It's not possible to have different tenants in the cloud. This creates problems when trying to create SaaS offers based on IBM B2B Integrator, as there is the possibility that some workflow for a customer can be visible to another one. Since it's not multi-tenant, it's running on the same tenant of the platform. This is the main issue that the platform has.

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.

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

Pros

"Out-of-box process orchestration yields quick implementations."

"It can scale horizontally as well as vertically as a cluster."

"It is easy of use and it's easy to maintain. It's also faster to on-board partners."

"When we gauged them, we found the Sterling Integrator is really flexible and is able to support a lot of business use cases when compared with the other technologies."

"B2B Integrator is multi-platform, so it can be integrated with Windows, Unix, or whatever, and it can work with almost all programming languages. It can also transfer a lot of data in a short time. For instance, a system I recently implemented exchanges about 20 million files a day."

"It's a stable solution."

"B2B Integrator's stability is rock-solid; it never goes down, and it's one of the bank's most prized uptime software products."

"It's easy to collect, diagnose, and transform, and to do real-time analytics through that."

More IBM B2B Integrator 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."

"Being a manufacturing company, we are dealing with different customers and catering to different orders, and EDI is very helpful for us because the ordering can be done via EDI and the orders can be processed outright, which is a big advantage."

"If you're in retail domain and are dealing with customers, then this is a good solution for you."

"The B2B Sterling platform is basically managed services, so we outsource our services to IBM and it relieves us of having resources in-house and 24/7 support."

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

"Overall, for how we use it and the way our organization is arranged, this solution works very well for us."

"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."

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

More IBM Sterling B2B Integration Services pros

"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."

"It is the best integration platform for those who are looking to implement or are going for API-based architecture and microservices-based architecture."

"We have seen a significant improvement in our processes: Response time decreased significantly and integration of services became faster."

"It is an ESB that can deploy seamlessly on-premises and in the cloud with strong API management and governance and has a strong integration with open source products like JBPM and Drools if these features are part of your requirements."

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

"Easy connectivity and easy integration."

"The solution improved my company by modernizing the way we offer services and improving the user experience."

More Mule ESB pros

Cons

"The communication logs are very poor. They are not easily understood, and we need to navigate to many places for many reasons."

"It doesn't support the Turkish language now."

"The dashboard is not integrated and should be bundled by the product vendor."

"The initial setup is complex."

"API integration could be improved. The legacy system could be on the cloud."

"They do not have a solid partner ecosystem, and they do not have a clear roadmap for down the line; they're missing that clear roadmap."

"With Sterling Integrator, as it comes out of the box, there's not a lot of things that have been developed; a lot of it you have to develop yourself with BPML and developing APIs and things like that for web solutions and the front end."

"They do not have a solid partner ecosystem, and they do not have a clear roadmap for down the line; they're missing that clear roadmap."

More IBM B2B Integrator cons

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

"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."

"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 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."

"Onboarding on the solution is complex."

"They can improve APIs because they are still lagging behind in API connectivity."

"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."

More IBM Sterling B2B Integration Services cons

"The payment system needs improvement."

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

"It's not easy to troubleshoot and we still can't make it work."

"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."

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

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

"MuleSoft isn't as mature as some other integration technologies out there like IBM WebSphere. There's room for growth, and MuleSoft is working toward that."

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

More Mule ESB cons

Pricing and Cost Advice

"The solution is priced at $20,000 to $30,000 per year with no extra costs."

"The price of IBM B2B Integrator is too high. However, IBM may be willing to give a discount if there are negotiations. If they see that there is a good opportunity for them they can provide a discount."

"We pay an annual fee based on the number of VPUs. It's fairly reasonable. We're in the middle of analyzing other products, and they're all pretty much in the same range."

"The product costs more than 40K."

"The pricing is based on how many cores are used and the type of cores."

"Licensing depends upon the package you opt for within the solution. The solution is a bit costly compared to the other integration tools in the market."

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

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

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

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

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

"The pricing must be improved."

"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."

"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."

"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."
