Room For Improvement

Mule ESB faces criticism over documentation, setup complexity, pricing, stability, scaling issues, regulatory challenges, and frequent release versioning.
Oracle Service Bus requires improvements in logging, error handling, integration, documentation, installation, security, scalability, and modernization to enhance usability.
More information is needed from MuleSoft.
From my perspective, Mule ESB is lightweight, but it can be improved when it comes to the agility of the system.
This can happen due to legacy systems that might not allow the use of microservices.
 

Setup Cost

Mule ESB is costly, especially for small businesses, but its robust features and integration support offer significant value.
Oracle Service Bus pricing is high with licensing complexity, but valuable in bundles and suitable for large enterprises.
I view both Oracle and IBM products as expensive.
 

Valuable Features

Mule ESB offers user-friendly integration with robust features like connectors, data transformation, cloud integration, and microservices support.
Oracle Service Bus simplifies integration with diverse applications through comprehensive adapters, robust data handling, and a user-friendly interface.
They have their own language called DataWeave, which helps transform data and is efficient enough to handle any kind of transformation.
The best features of Mule ESB are that it's very robust and solid; I find that even our legacy systems go well with ESB.
The main advantage of Oracle Service Bus is the possibility to integrate different systems using workflows and different architectures in the same product.

Featured Reviews

PurbayanSaha - PeerSpot reviewer
Has API-led architecture and provides a unique, user-friendly, and scalable architecture for hosting APIs
There's room for improvement in multi-file transfer functionality. It's not convenient when using MuleSoft, and it should have better capability for handling large amounts of data. For example, applications like GoAnywhere can handle huge chunks of data, so the tool should also have something to facilitate that aspect of integration.
Awa Sri - PeerSpot reviewer
Offers valuable features of API management and protocol definition
The initial setup process of Oracle Service Bus is quite easy. The installation of the product can be completed in one or two hours, but the total deployment time varies from case to case. I believe the entire deployment of Oracle Service Bus can be finished within a day. One engineer is enough to deploy the solution. The solution can be easily maintained.
