How MuleSoft Works

An Introduction to the technical architecture behind Mulesoft

MuleSoft is a hot topic in the CRM world, and for good reason! The software equips IT teams with the mechanisms they need to orchestrate seamless data transfer, foster holistic visibility across their organisation and provide a 360-degree view of each customer. This article explores the technicalities of MuleSoft in detail. 

If you’re looking for a more entry level introduction to the MuleSoft Anypoint platform and overview of the benefits , take a look at our article ‘So, What Does MuleSoft Actually Do?’.

What is MuleSoft?

The Mulesoft Anypoint Platform is the world’s leading integration platform for APIs, Software as a service (Saas), and Service-oriented architecture (SOA). Essentially an ESB (Enterprise Service Bus), tne of the biggest advantages of] MuleSoft is its unmatched ability to provide exceptional business agility to organisations of all sizes by connecting devices, data, and applications, both in the cloud and on-premises. MuleSoft is middleware that acts as an intermediary between different apps, systems, or components to facilitate communication, data exchange, and integration.

What is an Enterprise Service Bus?

An Enterprise Service Bus (ESB) is a software architecture pattern used for integrating various applications and services within an enterprise. As middleware, it provides a centralised platform that facilitates communication and the exchange of data between different systems, applications, and services.

Key features and functions of an Enterprise Service Bus include:

Message Routing:

An ESB allows for the routing of messages between applications and services. It acts as a central hub that intelligently directs messages based on defined rules and configurations.

Message Transformation:

An ESB can handle the transformation of messages between different formats or protocols, ensuring that systems with varying data structures can communicate effectively.

Service Orchestration:

An ESB supports the orchestration of services, allowing for the coordination and sequencing of multiple services to achieve a particular business process or workflow.

Protocol Conversion:

An ESB can manage protocol mediation, converting messages from one communication protocol to another. This is beneficial when integrating systems that use different communication standards.

Integration with Legacy Systems:

ESBs often provide connectors or adapters to facilitate integration with legacy systems, allowing older technologies to interact seamlessly with modern applications.

Security and Transaction Management:

ESBs often include features for managing security aspects such as authentication and authorisation. They also help in handling transactions across distributed systems.

Monitoring and Management:

ESBs typically offer tools for monitoring the flow of messages, tracking performance metrics, and managing the overall health of the integrated systems.


ESBs are designed to be scalable, allowing organisations to expand their integration capabilities as the volume of data and the complexity of integrations grow.

Loose Coupling:

ESBs promote a loosely coupled architecture, where applications and services are connected without strong dependencies. This flexibility makes it easier to modify or replace individual components without disrupting the entire system.

The beauty of MuleSoft is that it delivers all of the above, and more, applying declarative code for a user-friendly and efficient deployment process. Using repurposed API connectors stored in the software, Developers and other users can easily deploy new integrations in the platform’s ‘Composer’. Leveraging MuleSoft, organisations can swiftly create scalable integrations that harmonise the breadth of data across all facets of the business.
