Mule ESB Valuable Features
The features most impactful for my API management include the low-code, no-code concept. We have batch processing for handling large amounts of dataset. They have policy implementation, which is very easy, along with straightforward API designing.
Mule ESB's data transformation supports integration needs effectively. They have their own language called DataWeave, which helps transform data and is efficient enough to handle any kind of transformation.

View full review »We utilize data transformation capabilities extensively. For complex cases, we employ the SSLi engine, whereas for simpler ones like healthcare or response data, such as EDI 270 or 271. We prefer to use an external XRT engine instead of handling it within the ESB for ease of management. For smaller data transformations, we rely on DSPS.
View full review »It's open source, and there are a lot of community resources. Mule ESB makes it easy to connect to other software applications.

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.
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.
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 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.

IT Consultant at a financial services firm with 5,001-10,000 employees
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.

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.

- 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 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.
- Salesforce connector
- Enterprise JDBC
- SAP connector and other connectors like FTP and SFTP
- Parallel processing support
- JMS integration
- 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
DataWeave: It allows for complex mappings using a simple DSL (Domain Specific Language).

- 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.
