Neelima Golla - PeerSpot reviewer
Senior Software Engineer at NessPRO Italy
A hybrid integration platform that applies the functionality of closed-loop AI automation
I recommend using it because, in today's context, the cloud plays a significant role. Within the same user interface, you can develop applications and manage multiple applications, making it a more user-friendly option. Moreover, you can explore various other technologies while deploying on the cloud, broadening your knowledge of cloud technologies. In my case, the transition led to my learning of Kubernetes, enabling multi-scaling and expanding my technical skills. It was a valuable experience, and I had the opportunity to learn many new things during the migration process. I can easily rate it an eight or nine 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."
"In general, the solution works very, very well."
"Redirection is a key feature. It helps in managing multiple microservices by centralizing control and access."
"The flexibility is definitely a highlight. We have flexible mapping capabilities, allowing us to provide common mappings or create custom ones as needed."
"It's very scalable, which is one of the best features."
"It is a scalable solution because it can be scaled horizontally and vertically."
"I think the best part about WSO2 API Manager is that it's highly customizable because it's open-source."
"It handles millions of transactions of API calls per month in our reality, in the Lombardy region in Italy."
"WSO2 API Manager's most valuable features are the simple interface that is easy to use and the APIs lifecycle."
"The most interesting feature is its Mac-based function."
"Functionality-wise, I like WSO2 API Manager - Publisher API and WSO2 Enterprise Service Bus."
 

Cons

"The initial setup is not easy."
"The pricing can be improved."
"Enterprise bots are needed to balance products like Kafka and Confluent."
"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."
"What needs to be improved is the restriction that they have on the product."
"Its queuing and messaging features need improvement."
"The solution’s interface should be more user-friendly."
"The technical support must be improved."
"The documentation could be stronger and maybe the community support could be stronger."
"WSO2 API Manager should improve its marketplace subscription model and documentation in order to reach a higher level in the market."
"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."
"They don't have different URLs for administrators. They should have one in place like Kong."
"For fresh graduates and engineers, the setup process can be very difficult."
"From a product perspective, the first thing is that although the documentation provided by WSO2 is good, it could be much better. We're in the middle of a complex migration, moving away from VMs to Kubernetes with the latest version of WSO2 and good documentation is essential to us right now."
 

Pricing and Cost Advice

"It is an expensive solution."
"The solution's pricing model is very flexible."
"WSO2 API Manager is a low-cost solution. It is one of the most affordable solutions."
"The solution costs less than 20,000 euros a year. I'm not sure of the exact number."
"I think the other competitors that are providing the same solution are quite expensive. WSO2 API Manager is quite cheap."
"It is costly, around ten thousand per year, per instance"
"We use the open-source version of WSO2 API Manager, there is no cost."
"It is an open-source product."
"It's not expensive, but it could be cheaper."
"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."
