What is MuleSoft?
MuleSoft is a middleware, API Integration platform that allows enterprises to build robust integrations to alleviate their business needs and introduces various innovative solutions to expand the business.
- As per my understanding, MuleSoft introduced an architectural paradigm that combines SOA, some aspects of the MVC pattern, and Enterprise Integration patterns called API-Led Connectivity.
- It allows developers and architects to divide the APIs into specific layers such as Experience, Process, and System API.
💡 What is Middleware? What is API?
What is an API?
An API is like a blueprint/code that acts as an access point, a blueprint to all types of Systems. Assume that it is a black box that will execute and performs the specified function.
- MuleSoft provides us with these APIs for developers to implement their business logic using MuleSoft. The advantage of API is that we do not need a deep dive into how a system works internally.
- In the MuleSoft world, they are called Connector / Modules / Operations. Each connector provides a specific function that it will perform on the system.
What is Middleware?
A Middleware is software that acts as a software glue between systems by providing common ways to interact with systems via connectors.
- Enterprise Service Bus (ESB) is the architecture that allows us with a set of rules and principles over a bus-like infrastructure.
- The core concept of ESB is connecting to different systems by putting a communication bus or a software glue between them, decoupling various applications, and allowing them to communicate without any dependency.
- MuleSoft developed a runtime engine called Mule, a flexible ESB solution that will act as the glue between systems by providing pluggable connectors.
MuleSoft provides various connectors such as
There are many connectors by MuleSoft and other community developers. The below are few examples.
- Core: Few core connectors enable developers to build integrations in MuleSoft:
- Flow: A flow is a top-level component in a Mule application. It is the starting point of any integration in Mule.
- Transformers: Transforms and stores data.
- Async: Enable asynchronous processing.
- For-Each: The For Each scope is similar to a "for each" or "for loop" in most programming languages. Iterates through a collection. If a particular item in a collection throws an exception, the For Each scope will stop processing and invoke an error handler.
- Parallel For-Each: Splits the message into parts and processes each message part in parallel.
- Batch: Enable batch processing of records.
- Database: Connect to JDBC-compliant Databases
- Salesforce: Connect to Salesforce System.
- HTTP: A module to create HTTP(S) server or call an API via HTTP(S).
