Accessing information in its raw format is a big task for the business users. Many other enterprise customers do not gain a deeper understanding of data models or write code; they obviously require perspectives from data analysis. Without even a credible method of getting data from data sources and converting it into an easy-to-use format, the data has little meaning for the users who are in need.Among the most common enterprise service buses (ESB), Mule has the characteristics of being Java-based, lightweight, and acts as the runtime engine of a full hybrid enterprise integration framework for SOA, SaaS and APIs called the Anypoint platform. In this tutorial, we are going to cover the concepts like what is mulesoft, mulesoft ESB, ESB guidelines, ESb components, Mulesoft architecture, configuration, how to download and install mulesoft applications, mulesoft anypoint studio, etc.
Mule is a flexible enterprise service bus supported by the MuleSoft integration platform. This is a full JAVA-based framework, and this can bind to every other platform and APIs, such as Facebook, Twitter, LinkedIn, and several others.
MuleSoft enables designers to interact and communicate for any application, regardless of the language that is used to construct the application in a very versatile manner. Focuses on building an active line of communication between an integrated system to send and share data over a stable and secure network.

The data is geared at the developer who wants to create and incorporate APIs, servers and other frameworks into the advanced ecosystem. The main focus of this tutorial will be the developer working on ESB and the company looking to move their current application to the Mule world. Along with these two, this tutorial is useful to students and researchers who are interested in technology.
Now let's have a look at the core concepts in depth.
MuleSoft ESB (Stands for Enterprise Service Bus) is a web application tool developed by MuleSoft to incorporate N application numbers across linear bus-like infrastructure. It is a productive network that facilitates reliable exchange and collaboration of data across various applications. aThis ESB allows you to link the N number of the application over the Mule Bus and to maintain communication from one application to another without any interruption.
The intention of the Mule ESB is to distinguish applications from one another and to enable them to communicate in a fully managed and fast Bus network. It is a fully-tested controllable network device that also minimises the possibility of data loss. ESB can be incorporated using the Adaptor and the BUS as shown below.
Mule uses JMS and AMQP messaging servers that allow BUS communication to be introduced by dividing the application from each other. Bus implementation can only be accomplished by Mule Servers.
Adapters are responsible for behaving in a manner similar to a telephone network that enables you to connect from one person to another. In the same way, the adapter allows you to create a communication network to share data between applications.
ESB Bus enables a seamless transfer of information from one application to another. That way, Mule improves the overall degree of application communication over a single platform. Instead of just using several different apps and APIs across multiple channels to handle the application, Mule provides cloud-based application interpersonal communication networks to enable application interactions.Adaptors are not a single-end operation controller, but they also manage security, network failures, monitoring and message routing activities.
The principle guidelines of ESB are:
ESB has a large integration architecture that allows us to incorporate and run a variety of applications on a single platform. Let's see some of the essential places where ESB functionality can be included.
For a mid-level or relatively high framework, the quantity of implementations is increasingly growing with the need to include applications, web hosting, messaging, network manipulation, storage, as well as many other related concerns. With the P2P integration technique, you can create an application support architecture, but at the same time, the architecture will become more complicated as the number of applications increases. Even, P2P has allowed limitations on the accessibility of the platform and the language support.
Let us understand with this example.

Restricting access to a various platforms and the difficulty of multiple device integration generates the need to use Mule ESB. Mule ESB offers word-class flexibility to implement without any reservations about language support and compatibility problems with various device architectures. It improves the reusable capability of the framework by encapsulating the features of a single platform together. Applications can be easily integrated in a coordinated way.
The two components of mule ESb are service registry and centralized administration.
The major functionalities of the Mule ESB are:
1. Validate(V): The validation of the scheme is done by Validate. ESB uses a validation parser and a modified schema to verify the outlines of the schema. For example, you can examine the XML document to confirm the schema.
<?xml version="1.0" encoding="UTF-8"?>

2. Enrich(E): The intention of the enrichment is to add additional data to the message. Simply add more sense to the destination customer.
3. Transform (T): The process of transforming data to a sequential format that is readily available to the requester is called transformation. For example, when travelling abroad, you need to swap your currency in the country of destination currency, which makes the currency easily moveable to that country. Likewise, data also needs to be converted into a specified format for the acceptance for the requested application.
4. Routing (R): We can consider it a gateway or decision-maker of a service that offers a path to a service that allows you to switch between the source and the destination.
5. Operate (O): The word itself determines the functionality of the part. It either invokes the services needed or interacts with a particular request for service processing.
Mule ESB provides a wide variety of support features for applications, such as
MuleSoft includes the three-layer architectures for the integration of software and data processing. Application Layer, Integration Layer, Transport Layer. The architecture can be seen in the diagram below.

Mule Architecture can be designed and personalized in three types of tasks.
The mule configuration architecture consists of the following components. You can see them in the below diagram.

Up to now, you had gained the fundamentals of the mule, its operation, and the basic configurations required.
Let's get started by understanding the configuration of the machine and the framework needed to run the Mule code.
First, you need to confirm if your machine has JAVA JDK installed in it. You can download JDK 8.1.0 to support the setup of the Mule.
Mule supports a wide variety of operating systems to search the list below to know if your system includes all of them.
The different OS supported by mule are Windows 10, Windows 8.1, Windows 2016 Server, Windows 2012 R2 Server, macOS 10.11.x, , Ubuntu Server 18.04, Linux Kernel 3.13+, HP-UX 11iV3, Solaris 11.3, AIX 7.2 and RHEL 7, etc.
Now you need to check with the database that is required for the mule applications.
Database: Mule runs its standalone server so you don't need any extra support for this database use. But if you need to process or access data storage in Mule, you need to configure the server below. This will allow you to use the application server. You can use the following list such as Oracle 12c, Oracle 11g, MySQL 5.5+, IBM DB2 10, PostgreSQL 9, Derby 10, Microsoft SQL Server 2014, and System configuration to run Mule, etc.
