The most valuable features of Mule ESB are its ease of use, documentation, ease to adapt to newer security and vulnerabilities, and a lot of help available. Additionally, there is a lot of flexibility, many patches available, and they provide APIs. They are a market standard.

Most of our use cases are for Salesforce. So, the connectors for Salesforce have been really helpful. They've made development two times faster.

Mule ESB has a user-friendly design, and everything is in one place. The API and architecture are popular right now. Also, MuleSoft has a large and supportive online community. 

The HTTP, SAP and RabbitMQ connectors that we use are very easy to connect. The language for writing the transformations is also very simple. This is a useful solution. The solution doesn't require much code writing and we can develop APIs very easily. 

The connectors help to connect with a variety of applications. We have used connectors for Salesforce and Dynamics CRM. The file processing features are useful.

The solution's drag-and-drop interface and data viewer helped us quite a lot.

We can do very fast development of the orchestrations of MuleSoft. The design patents which we use for integration patents are also a nice feature. 

The solution also offers multiple deployment options. I like the endpoint time manager and the access policies. 

It's open source, and there are a lot of community resources. Mule ESB makes it easy to connect to other software applications.

I'm not using ESB directly. It is the integration layer, so it's running under the hood. However, the conversion and transformation performance is excellent. Anypoint Enterprise Security is also solid.

It is easy to use and easy to understand. 

It is easily deployable and manageable. It has microservices-based architecture, which means that you can deploy the solution based on your needs, and you can manage the solution very easily.

This tool has exceptional API management and integration connectors in addition to multiple out of the box connectors. 

The UI is good. From a development perspective, it's pretty easy and pretty intuitive for the developers to work with. We have fresh graduates who have started picking up MuleSoft. Its user interface is pretty intuitive.

• Deployment strategies: Mule supports a wide variety of deployment strategies.
• SOA architectural style: Mule can embrace the architectural style and SOA practices in place where it’s deployed.
• Focused on higher-level concerns: It deals extensively with all the details of integration and provides a wide range of connectors. It has the ability to be an integration framework open to all sorts of protocols.
• They have comprehensive and up-to-date documentation, a subject on which the vendor has made huge progress recently.

The most valuable feature is DataWeave. It allows for the transformation of data, for example to JSON or from JSON. It's very powerful.

There are also many connectors available, which is nice.

When we bought the solution, it was an in-the-cloud or PaaS solution. Because of that, I didn't have to take care of the infrastructure, which was a big plus.

It was pretty fast to develop APIs on this platform, which is something I liked about it. So, the time to value was pretty good. 

The most valuable feature of Mule ESB is data transformation, i.e. our interacting with different systems and orchestrating for our business needs. 

For example, a customer has liabilities in loans and credit cards, maybe some other mortgages, like four liabilities which are split into four systems. 

I need to expose an API that can tune the data from four systems and expose it into one single API. For that, I have to call our services and complex security policies.

Mule ESB loads complex web service security policies. Sometimes, we have some FLAC files or maybe some messaging services. We need to consume those components and expose them as an API, which is nothing but some adjacent format, i.e. a REST API.

Mule ESB is a very easy-to-use and user-friendly solution.

The connectivity the solution provides is excellent. There are often too many systems that we have to integrate and this helps with that.

The platform itself is very good.

• We can use Java expressions anywhere in the flow
• Provides API support out-of-the-box
• API management can be done using RAML

The best feature for me was the easy connectivity and easy integration. In comparison, if you go through code license for APN, it will require more configuration or more code but if you're going to Anypoint Studio and using Mule ESB, you just drag and drop the connectors, configure the credentials and complete your process as per your requirements. The product helps me a lot to integrate quickly. 

The most valuable feature is the Salesforce integration.

The drag and drop feature makes it very easy for transformation, and to use the Anypoint platform.

It is very easy to manage the flow using Anypoint.

The cloud and integration abilities are most useful allowing us to use applications such as Salesforce and DataWeave. Additionally, the exception handling is good. We have experienced zero downtime since moving to this solution.

There are many already defined endpoint components such as HTTP, JMS, FTP, etc., and these are the main tools for communicating with various services. By having these, developers just need to concentrate on the functionalities instead of making modules to talk to other services.

The transformation and the data format are the features that I like the most.

The most powerful feature is DataWeave, which is a powerful language where data can be transformed from one form into another. 

• Salesforce connector
• Enterprise JDBC
• SAP connector and other connectors like FTP and SFTP
• Parallel processing support
• JMS integration

Flexibility and high performance.

I can perform integrations with any environment and scenery as well as growth in apps integration, is an agnostic tool architecture ie can generate components on different architectures are JEE or .Net.  

Mule ESB has a lot components and tools that apply integration patterns making it easier to development without much knowledge of patterns

I am impressed with the product's connectors and scalability. 

• Writing your complex business logic as a simple workflow which can be understood by not so technical people
• Hot deployment of those workflows, which helps in automation and self-learning/healing.
• Provides a variety of connectors: SalesForce, Twitter, SAP, Facebook, and WebService consumer. Most of them come for free with the Community Edition.
• Async/concurrent execution of services within a flow
• Logging

The most valuable feature is that it's programmer-friendly, so it's very easy to develop APIs.

• Routing
• Enrichment
• DataWeave
• Choice of connectors
• Light weight containers
• Packaging and deploying
• API management
• Scalability and load balancing

I like that it's user-friendly. Compared to other ESBs, I find it easier to use. I like it better than other ESBs. I like the connectors, which make calling the APIs through the routers easier.

I like the graphical interface and the number of connectors. The solution is easy to maintain. 

The most valuable features are the connectors, DataWeave, and the way it simplifies the application development and deployable files.

Connectors:

• Being a Java developer, I have experienced how much logic and coding one needs to put in while accessing the database.
• With the DB Connectors developer, I just need to place the query, and in some cases the drivers, if Mule doesn't provide out-of-the-box support.
• With the HTTP Connector and the APIkit router with RAML, managing the resources and handling is made easy.
• With Mule's expected release in Q3 of 2017, generating RAML would also be made easy.

DataWeave:

• With good knowledge of DataWeave operators, anything can be achieved in a couple of lines of code, which otherwise would be time consuming in Java.

• Service Mediation: This is an abstraction layer in between the service consumer and the service provider.
• Message Routing: This feature consumes messages. It filters, enriches, and performs necessary operations on a message. It redirects them to the appropriate target endpoint, based on a certain decision making criterion.
• Data Transformation: The process of converting/transforming data or information from one format to another.

I like that Mule ESB provides fast and good technical support.

The features that I have found most valuable are that the product is updated regularly and Mule's framework. Overall the performance is good.

For our current solution, I think what Mule provides out-of-box is a sufficient product.

The most valuable feature for Mule is the number of connectors that are available. There are a lot of connectors to different systems so if you want to connect to SAP or Salesforce, there are readily available connectors that are of great help. It saves a lot of time using this system.

The level of integration that this product offers is quite far ahead of the competition.

They have a very strong developer community, interacting at an informal level on a daily basis.

Mule ESB is quite lightweight.

Everything runs in Java, which is a useful feature.

In order of importance:

- Connectors

- Data Weave

- Mule Expression Language

DataWeave: It allows for complex mappings using a simple DSL (Domain Specific Language).

Connectors: It has many connectors and components that really help to complete the development very quickly.

The architecture based on events: It has several connectors which allow integration from external and internal applications of the company.
