Fuse ESB tutorial

What is Fuse ESB?

ESB stands for Enterprise Service Bus. The Enterprise Service Bus is a platform that is designed and developed as a middleware that is used as a scope of communication between multiple applications. The main goal of the Enterprise Service Bus is to rectify the problem of integration by acting as a hub that is situated in between all the applications and facilities message routing between them. The enterprise service bus acts as a mediator, which acts as an information highway, providing it support to the radio transformation routing, allowing the developer or the coder to focus on his own application logic. 

Each application would need the input and output data in their own format and this approach will work the best if the number of applications is less. But we know that there is a high demand with applications and hence we will need an application that would be able to meet the business changes, enhancements, and integrate with a better approach. 

The enterprise service bus does not require any application to be directly communicated with the other application. Instead, the applications will need to communicate with the enterprise service bus and the enterprise service bus will make sure and handle the routing of the information and the internal data format conversion that is needed.

Why fuse ESB? 

Fuse ESB is known for its importance and popularity because of the immense support that is provided to the users. Let us gain an understanding of the most important points that need to be considered to explain that the enterprise service bus is essential. 

1. The primary goal of the enterprise service bus is to simplify the problem of integration with the different or variant compatible applications. 

2. The enterprise service bus accesses a middleware, serving as a mediator for all the applications that facilitates message routing between them. 

3. It provides flexibility to users as it does not require every application to interface with every other application directly, and can utilize only one interface which is ESB. 

4. The enterprise service bus is also responsible for message transformation which helps in transforming the messages or translating the messages from a common format and then route the messages accordingly to their destinations. 

5. The most important objective or goal using this enterprise service bus approach is that it allows you to utilize only one interface when you would like to replace any of your existing applications instead of writing the whole bunch of the new interfaces. This includes a feature of reusability which helps saving time and efforts.

Components and architecture of Fuse ESB: 

Let us gain an understanding of the different components involved in the architecture of Fuse ESB. 

1. Apache CXF: Apache CXF is one of the components of Fuse USB that is considered as an open-source Web Services development framework. It provides extensive support in the development of the SOAP and Rest Web Services. 

2. Apache camel: This is one of the most important components or frameworks which is really based on EIP integration. EIP here refers to Enterprise Integration patterns which help in identifying the solutions for the recurring problems that occur in the enterprise integration. It allows you to write the routing logic in several different domain-specific languages like Java, DSL, Scala, Spring, etc. 

3. Apache AMQ: Apache MQ is a JMS that provides a reliable messaging system as per JMS standards. It does not provide the support only to the JMS specifications but also provides extensive support to some exciting and useful features which are not included in the part of JMS specifications. 

4. Apache karaf: Apache karaf is considered as a lightweight OSGi container that helps in acting as a runtime for the artifacts. Apache karaf is more dynamic in nature than the Java Virtual Machine. The deployment of all the artifacts in the fuse is done in karaf

5.Fabric: Fabric is one of the components that help in managing the deployments of the artifacts in a distributed and large environment, and also provides its extensive support via centralized management from the multiple fuses instances.

Benefits of using Fuse ESB:

Fuse SEB has come up with many benefits. Let us have a brief understanding of the benefits of Fuse ESB.

• It provides a faster solution to the business organization as it is based on the commonly used enterprise integration pattern which is based on Apache Camel Framework.
• It is a platform that helps in integrating all the enterprise assets with additional features like extensive connectivity options.
• It is a foundation that helps in running the integration capability in the cloud. It is easier to configure, monitor, manage, and maintain the systems easily.
• It provides multiple deployment options which are a lightweight, smaller IT footprint, etc, along with the low cost of ownership. It allows the users to get started easily with an easier set of the pricing available for startups as well.

Conclusion:

It is important for the organization to maintain a platform that helps in collaborating with multiple applications and provide business functionality as a whole, based on the client requirements. The integration part of these applications is one of the most occurring problems that is being faced by organizations and it has been difficult in the current times because of the increase in the applications. The Fuse ESB is the platform that has been solving recurring solutions. I hope the above information is helpful to you. I would recommend you to get trained and certified in Fuse ESB  for a great opportunity ahead.
