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

"Redirection is a key feature. It helps in managing multiple microservices by centralizing control and access."
"Cloud Pak for Integration is definitely scalable. That is the most important criteria."
"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."
"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."
"It is a stable solution."
"We have been extremely happy with WSO2 API Manager as it helped us quickly publish our Microservice APIs with features like security and throttling policies, provides complete access to customize APIs which saves development effort and time, and offers a very stable, scalable, and easy-to-configure platform that is also affordable and simple to use overall."
"WSO2 is very stable."
"The advice I have for any of the organizations or companies looking for an API manager is that they, first of all, verify the building block before selecting a product."
"I definitely recommend this solution."
"One of the great things about WSO2 API Manager is that it is so easy to adopt. And because it's an open source solution, we're able to extend the implementation any time to suit our company needs better."
"The most beneficial feature of WSO2 API Manager is its capability to use Swagger to define and then populate the API."
"Most of the time, we need to install a plug-in without having any lapse in services or restarting the application, and the WSO2 platform can do all deployments without any downtime."
"It handles millions of transactions of API calls per month in our reality, in the Lombardy region in Italy."
 

Cons

"The pricing can be improved."
"Enterprise bots are needed to balance products like Kafka and Confluent."
"Its queuing and messaging features need improvement."
"What needs to be improved is the restriction that they have on the product."
"The initial setup is not easy."
"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."
"For fresh graduates and engineers, the setup process can be very difficult."
"The initial setup can be difficult."
"They don't have different URLs for administrators. They should have one in place like Kong."
"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."
"The documentation could be stronger and maybe the community support could be stronger."
"Providing easy configuration for email and SMS notifications, layout and customization of admin and developer landing pages."
"The professional support and licensing aspects of WSO have been a challenge."
"I wouldn't actually recommend this to anyone. Personally, I wouldn't recommend this solution at all."
 

Pricing and Cost Advice

"The solution's pricing model is very flexible."
"It is an expensive solution."
"WSO2 API Manager is an open-source solution."
"We use the open-source version — the free version."
"As far as I'm aware, the costs are not minimal but satisfactory."
"It is an open-source product."
"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."
"For our projects, we found the pricing to be a little high."
"I am using the free version."
"The solution costs less than 20,000 euros a year. I'm not sure of the exact number."
