MANUEL VALDIVIA - PeerSpot reviewer
Routes messages efficiently across our services, but the features for scalability need improvement
One of the key benefits has been its ability to expose services and securely integrate applications within our architecture. It's been integral in maintaining a stable infrastructure despite its limitations with dynamic service creation and flexibility compared to newer technologies like Kubernetes. The main challenge has been scalability during peak usage times.
Maharsh-Kapadia - PeerSpot reviewer
Transforms enterprise integration with comprehensive platform and excellent support
The best features of this solution are that everything we get into a single platform, whether it's integration, API, or data modeling; everything is available in one platform. It's a hybrid, including cloud and on-premise solutions with good connectivity and good connectors. From the benefits of using Mule ESB, we could reduce the manual tasks to 50% in one to two years. The cost is still something we are trying to make lower because we see some advantages when we move from point-to-point integration to API-led connectivity. We have seen a lot of reusable assets, so the cost is reduced. Ultimately, we want to see how it's transformed into business revenue; that's what we are still looking into.
