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

"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."
"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."
"Redirection is a key feature. It helps in managing multiple microservices by centralizing control and access."
"It is a scalable solution because it can be scaled horizontally and vertically."
"Its open-source features are very good, especially for your production work."
"Most of the time, we need to install a plug-in without having any lapse in services or restarting the application. The WSO2 platform can do all deployments without any downtime."
"The scalability is fine for our purposes."
"WSO2 API Manager is easy to use."
"WSO2 is very stable."
"Functionality-wise, I like WSO2 API Manager - Publisher API and WSO2 Enterprise Service Bus."
"A complete integration suite and a good platform."
 

Cons

"Enterprise bots are needed to balance products like Kafka and Confluent."
"Its queuing and messaging features need improvement."
"The initial setup is not easy."
"The pricing can be improved."
"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 interface needs to be modernized and made more user friendly so the product continues to have a growing community of users."
"Lacks some new features and updated functionalities."
"The user interface could be a bit better."
"Dashboards for application monitoring of the APIs would be beneficial, allowing us to check for faulty APIs."
"The initial setup can be difficult."
"WSO2 API Manager could improve the API approval system."
"We found WSO2 API Manager to be a bit complex."
"I would like it to be a more stable solution. Maybe in the last version that is approved. For me it would be good if they had a community established version."
 

Pricing and Cost Advice

"It is an expensive solution."
"The solution's pricing model is very flexible."
"It is costly, around ten thousand per year, per instance"
"WSO2 API Manager is a costly solution, and its pricing is not competitive enough compared to other products."
"It is an open-source product."
"It's not expensive, but it could be cheaper."
"I am using the free version."
"I think the other competitors that are providing the same solution are quite expensive. WSO2 API Manager is quite cheap."
"We use the open-source version of WSO2 API Manager, there is no cost."
"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."
