The technical support of Mule ESB can be rated from nine to ten.
I rate the technical support from Oracle a nine out of ten.
 

Scalability Issues

Sentiment score
7.6
Mule ESB is scalable, ideal for cloud deployments, and suits medium to large enterprises with proper configuration.
Sentiment score
7.0
Oracle Service Bus is scalable, excelling in enterprise scenarios but facing challenges with memory, complexity, and cloud scalability.
Sentiment score
7.2
webMethods.io is praised for its scalability in cloud and on-premises environments, with some licensing constraints noted.
Mule ESB is a scalable solution.
There are dependencies on the Java version and application being used.
Whenever more resources are needed, they become available automatically without any human interference.
Vertically, scalability is fine, however, I have not expanded horizontally with the product yet.
 

Stability Issues

Sentiment score
7.2
Mule ESB is generally stable and reliable, but improvements are needed in clustering, large files, and CloudHub stability.
Sentiment score
7.9
Oracle Service Bus is highly stable and reliable, often rated 8 or 9 for stability by users.
Sentiment score
7.6
webMethods.io is generally stable and reliable, with minor issues in specific modules and cloud version maturity needed.
I rate the stability of the product as eight out of ten.
We provide support to our clients, and the minimum calls I receive are for webMethods.io; it's very stable.
There are some issues like the tool hanging or the need for additional jars when exposing web services.
 

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.
webMethods.io needs clearer documentation, better scalability, intuitive interfaces, and improved integration and cost-effectiveness for enhanced user experience.
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.
webMethods.io lacks advanced monitoring and analytics capabilities, so my customers need to use something additional.
A special discount of at least 50% for old customers would allow us to expand our services and request more resources.
 

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.
Enterprise buyers find webMethods.io costly but valuable, offering flexibility and comprehensive solutions, particularly beneficial for large-scale enterprises.
I view both Oracle and IBM products as expensive.
Regarding the pricing and licensing of webMethods.io, I don't think it's expensive when compared with the features.
 

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.
webMethods.io excels in seamless integration, user-friendliness, robust security, and scalability, offering efficient tools and reliable management for diverse needs.
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.
It facilitates the exposure of around 235 services through our platform to feed various government entities across the entire country.
I believe data transformation is exceptional in webMethods.io because they have an online database that can cache the database online.

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.
