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.

Effortless integration with REST APIs enhances business process management
The product's capabilities for integrating with REST APIs are valuable. We use API key-based security integration, where API keys are exchanged between the REST APIs. This ensures security. In the future, we might also use OAuth-based integration. Internally, the business process manager allows us to define the process and integrate with it. Additionally, the capability to define processes and seamless integration with APIs enhances our operations.

Quotes from Members

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

Pros

"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 stable solution."
"The most valuable aspect of the Cloud Pak, in general, is the flexibility that you have to use the product."
"Based on the information I have, the solution's most valuable feature is its capability of implementing custom solutions."
"WSO2 API Manager's most valuable features are the simple interface that is easy to use and the APIs lifecycle."
"The capability to define processes and seamless integration with APIs enhances our operations."
"It's a good product."
"We could easily deploy APIs on WSO2 API Manager, and CORS configuration was easy to manage."
"This solution is a little bit faster, easier to use, and has better integration than the other solutions I have experienced."
"WSO2 API Manager is easy to use."
"Its open-source features are very good, especially for your production work."
 

Cons

"Enterprise bots are needed to balance products like Kafka and Confluent."
"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."
"Its queuing and messaging features need improvement."
"The initial setup is not easy."
"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."
"WSO2 API Manager could improve the API approval system."
"Based on our recent large scaling project, the latency needs to be improved."
"The stability is pretty good, but it could be improved."
"They don't have different URLs for administrators."
"I would like to see improvements in the speed of the solution as it can be a bit slow compared to other platforms along with addressing memory issues would be beneficial."
"API Manager is not easy to scale because some of its components lack scalability. It's a difficult point. Especially because companies are so cloud-based these days, microservice scalability is a major thing."
"I can say that user management is not really flexible. So, if I want to create 1,000 store users, I can't do it as a publisher. You have to register as a store user using the store URL."
 

Pricing and Cost Advice

"It is an expensive solution."
"The solution's pricing model is very flexible."
"The solution costs less than 20,000 euros a year. I'm not sure of the exact number."
"My previous company paid about 1.2 million dollars, and my current company pays about 300k. Both companies are at the enterprise level."
"It is an open-source product."
"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."
"It's not expensive, but it could be cheaper."
"I am using the free version."
"For our projects, we found the pricing to be a little high."
"As far as I'm aware, the costs are not minimal but satisfactory."
