Efficient data transformation and seamless integration drive successful deployments
As for improvements in IBM Integration Bus, we are getting another feature of the retry mechanism now. Version 8.13 was upgraded, and we started using the retry mechanism itself, and we are using nodes in the development level. They are improving one of the nodes such as the HTTP request node, implementing the indirect retry mechanism itself, and we are getting new features.

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.

Cheif Specialist- Licensing Systems at Roads & Transport Authority
A robust product that needs to improve the functionality it offers related to API lifecycle management
Scalability-wise, I rate the solution a six to seven out of ten. My company consists of around 7000 employees, and we use the solution as an integrated service in around 300 to 400 systems, both internally and externally, making it a huge number. Our company uses the solution every minute and every second, and we can't function without it.

Quotes from Members

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

Pros

"It aligns well with containerized environments, which increases its scalability and high availability."
"I consider the solution to be one of the most stable in the market, in comparison with others such as Oracle and this assessment I maintain on an ongoing basis."
"The product helps efficiently work with different connectors from different back-end systems."
"The most valuable feature is that it is clear and easy to learn."
"I found all features valuable."
"It is very straightforward. It is very user-friendly integration."
"The stability is mostly pretty good."
"The message queue feature is very valuable."
"We suggested that clients switch to Mule ESB due to the lower licensing cost, the availability of cloud connectors, the CloudHub platform supporting iPaaS, and a suite of 110+ connectors to use."
"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."
"It's open source, and there are a lot of community resources. Mule ESB makes it easy to connect to other software applications."
"Mule ESB is the heart of applications that require routing and improvement of messages such as electronic invoicing."
"The solution has helped us to develop more quickly and improve our time to market."
"The most powerful feature is DataWeave, which is a powerful language where data can be transformed from one form into another."
"The solution improved the company by modernizing the way they offer services and improving the user experience."
"Mule ESB helps a lot with our microservice architecture that we're trying to build, and it is still our go-to technology when it comes to that, so it's very promising for us."
"It's very stable and reliable."
"The GUI and IDE features of this solution are easy to work with and to develop, and we find application management easy using this solution."
"The most valuable feature is that it is a service-oriented architecture, SOA-based."
"This is a good platform but in our case, it needs to be updated."
"TIBCO has proven to be far superior, and we later realized that the capabilities that TIBCO had were far, far superior to what Oracle was able to offer so we chose TIBCO instead."
"The product’s most valuable feature is stability."
"The technology is really easy to learn."
"It is easy to develop. It has a very wide range of features. The older versions are very stable, and there are no issues with the product."
 

Cons

"IBM doesn't really have a very strong community surrounding the product. Most of its direct competitors are open source solutions, and those have an excellent and well-developed community around the tech to help users navigate the ins and outs of the product. IBM is lacking in this area."
"I would like to be able to build an Integration Bus cluster that is active-active."
"Some of the runtime properties need to be improved because if you want to load certificates as sales security, you have to restart the server."
"The solution is too expensive for smaller companies."
"The memory footprint needs to be improved; having this solution on-prem is taking more memory and that memory footprint should be minimized."
"One drawback that I have found is that there are issues with using the Java connector."
"Kafka is much faster. The performance is much greater than IIB. IIB is not as fast as Kafka."
"The next versions are moving toward container use. It would be a shame to make the product highly complex just to support one pattern of deployment. It is my hope that IBM continues to focus on practical functionality that is simple and cost-effective."
"The documentation is not extensive and is limited to examples which are too basic."
"It needs more samples. Also, the dependency on Maven should be removed."
"It should have some amount of logging."
"Lacking some connectors that could be included."
"Its licensing or pricing model should be improved. If I compare it to other solutions, it is very expensive for small and medium businesses."
"The Mule IDE (Integrated Development Environment) could be more stable."
"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."
"Limitation on external subscribers to listen to the messages on the bus."
"Issues with the support, the fees, and the termination of the professional services are reasons we are looking for other solutions."
"The initial setup process could be easier."
"The stability of their latest version is not on par with their classic version 5.X."
"The intermediate version that we are using has stability issues. These stability issues should be resolved, but it seems like TIBCO is not focusing on resolving these issues. The resolution timelines are quite high even for high-priority incidents. Its price should be lower. Its licensing cost is considerably high as compared to other ESBs."
"Our version does not have cloud capabilities. Containerization is not supported."
"In the configuration, where we need to customize, it takes more time that we expect it to, ideally."
"If TIBCO could be able to sort the size of their base image in the Container edition, it would be really marvelous. Right now it's around 299 MB. We'd really want it to reduce to a few MBs."
"In the configuration, where we need to customize, it takes more time than we expect it to, ideally."
 

Pricing and Cost Advice

"IBM is expensive."
"The maintenance and support of the product are very expensive."
"I generally do not get involved in the licensing or pricing because I'm a hardcore technical guy, but I'm aware of the fact that IBM is highly expensive, so not everybody can afford it. All the products are licensed."
"The price is reasonable considering the features we receive."
"IBM Integration Bus is expensive."
"The pricing could be improved to make it more competitive."
"IBM Integration Bus solution is expensive and this is one of the reasons we are looking for an alternative, such as MuleSoft."
"IBM Integration Bus is expensive. There are cheaper products in the marketplace."
"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 licensing is yearly, and there are additional fees for services."
"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."
"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."
"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."
"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 various features and components for this solution are no longer free."
"When it comes to cost, TIBCO is much more competitive than a product like Pega."
"Its licensing cost is considerably high as compared to other ESBs."
"Price-wise, I would say that the product is expensive."
"The price is on the higher side. For the same price, if I go to the previous version, I would have got a lot more capacity with similar kinds of features."
"The biggest issue disadvantage of TIBCO is that it is expensive."
"The licensing cost is a challenge for quite a few customers."
