Manages APIs and integrates microservices with redirection feature
IBM Cloud Pak for Integration includes monitoring capabilities to track the performance and health of your integrations. You can quickly roll back to a previous version if an issue arises. Additionally, it supports incremental deployments, allowing you to shift traffic to a new version of an API gradually. For example, you can start by directing 10% of traffic to the new version while the rest continue using the legacy version. If everything works as expected, you can gradually increase the traffic to the new version over time. IBM Cloud Pak for Integration has a client base that includes numerous organizations using AI and machine learning technologies. We leverage an open-source machine learning framework and integrate it with Kafka to help create and manage various products and data retrieval processes. For companies with private data, the framework first retrieves relevant data from a GitHub database, which is then combined with the final request before being sent to a language model like GPT. This ensures that the language model uses your specific data to generate responses. Kafka plays a key role by streaming real-time data from file systems and databases like Oracle and Microsoft SQL. This data is published to Kafka topics, then vectorized and used with artificial intelligence to enhance the overall process. It's like an old-fashioned approach. The best way is to redesign it with products such as Kafka. Overall, I rate the solution an eight out of ten.

Middleware integration has become smoother and manages API lifecycles and scopes effectively
Regarding WSO2 API Manager, I have no drawbacks or areas for improvement. However, regarding the Micro Integrator, I had some issues while developing complex services because it was mainly designed to be used for simple services, not complex ones. While using complex services, I encountered some issues. I communicated this with WSO2, and they released other products that solved everything related to my concern. These products were released before my concern was raised. When I explored them, they were pretty good, and I did not see the same issues I had experienced. WSO2 is enhancing themselves, and their products are fine. The previous concern was about the previous product, so it is resolved now since there are new products available. I would like WSO2 to improve quality or response time in support, or both.

Quotes from Members

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

Pros

"Redirection is a key feature. It helps in managing multiple microservices by centralizing control and access."
"It is a stable solution."
"The most valuable aspect of the Cloud Pak, in general, is the flexibility that you have to use the product."
"In general, the solution works very, very well."
"The most preferable aspect would be the elimination of the command, which was a significant improvement. In the past, it was a challenge, but now we can proceed smoothly with the implementation of our policies and everything is managed through JCP. It's still among the positive aspects, and it's a valuable feature."
"Cloud Pak for Integration is definitely scalable. That is the most important criteria."
"The user interface is easy to navigate, and the documentation is extensive. It's open-source, so everything is available, and we can create what we need. That's not necessarily a feature, but it's an advantage."
"The solution is open-source, fully containerized with a micro-gateway, scales up and down easily, is not a monolith, and offers a flexible stack with components like a micro-integrator, analytics, streaming integration, and identity access management that fit well to my requirements."
"This solution is a little bit faster, easier to use, and has better integration than the other solutions I have experienced."
"Yes WSO2 API Manager is scalable"
"There are a lot of tools to help the manager. WSO2 is very easy to install. It has all the principal functionalities that you think about when you want to put up the management solution. It's a very friendly tool."
"It is possible to scale up and scale down with the solution...I can say that I have not seen any issues related to scalability."
"The capability to define processes and seamless integration with APIs enhances our operations."
"Functionality-wise, I like WSO2 API Manager - Publisher API and WSO2 Enterprise Service Bus."
 

Cons

"Enterprise bots are needed to balance products like Kafka and Confluent."
"The pricing can be improved."
"Its queuing and messaging features need improvement."
"What needs to be improved is the restriction that they have on the product."
"Setting up Cloud Pak for Integration is relatively complex. It's not as easy because it has not yet been fully integrated. You still have some products that are still not containerized, so you still have to run them on a dedicated VM."
"The initial setup is not easy."
"For fresh graduates and engineers, the setup process can be very difficult."
"WSO2 API Manager could improve by adding external API security features, which is one area where there is room for enhancement. Internally, API security is strong, and all other necessary features are already available. It has a solid marketplace, supports both Docker and standalone setups, and offers great enterprise integration. The developer portal has greatly improved the user experience, making it simple and user-friendly wherever we’ve implemented it. Overall, it’s not as complicated as other API gateways."
"I would improve the product documentation. There are some gaps, and it can be difficult to find the proper documentation for the product if you need to solve something."
"The user interface provides all functionalities to configure and manage the product, however its usability, especially for first-time users, is a little bit rough compared to the UI of other commercial API Managers."
"WSO2 API Manager could increase their security compliance."
"I'd like to see some new features and updated functionalities."
"Based on our recent large scaling project, the latency needs to be improved."
"The solution could be more user friendly for engineers."
 

Pricing and Cost Advice

"It is an expensive solution."
"The solution's pricing model is very flexible."
"For our projects, we found the pricing to be a little high."
"It is costly, around ten thousand per year, per instance"
"My previous company paid about 1.2 million dollars, and my current company pays about 300k. Both companies are at the enterprise level."
"The challenge is the increasing pricing, which has led some customers to consider alternatives, like using Spring Boot solutions instead. The rising costs, especially as cores and usage increase, have been a concern, prompting some to migrate to other products."
"We use the open-source version — the free version."
"We have not opted for the paid version of WSO2 but we have implemented the free and open source WSO2 software to a great extent and it is working as per our expectation."
"WSO2 API Manager is a low-cost solution. It is one of the most affordable solutions."
"We use the open-source version of WSO2 API Manager, there is no cost."
