JBoss Fuse ESB Interview Questions

1: What exactly do you mean by the term integration? How can it be implemented in business?

Well, integration is nothing but attracting two different devices, applications, machines, tools, or anything with each other for achieving a specific result or to accomplish a specific task. It has become vital for businesses because it helps them perform their tasks reliably and quickly and in fact, without investing a lot of money. A lot of business in the present scenario is adopting this technology to keep up the pace.

2: Can the task of a business depend on a single app? What if not or they are present at specific locations?

These days’ businesses are becoming more and more complex to understand and to maintain. It is not possible for any organization to maintain everything with a single application. Of course, there is always a need for a lot. Many times their applications are not present exactly where they want but it remains present in another branch office. During such a situation, the FuseESB approach can be considered as it offers very reliable results to get the most desired results in this matter.

3: What is application integration? What is its significance?

Application integration means accessing a specific application from multiple locations when it is present at a defined location only. In other words, application integration means joining or fixing different application of a business with each other so that they can be accessed anytime anywhere by the authorized users. It saves costs and ensures faster operations. A lot of businesses have started considering this approach due to the diverse array of benefits that they can have. 

4: What exactly is digital transformation according to you?

Digital transmission is a process of sharing information digitally. Any information or data is generally present in its specific format which cannot be integrated or shared as it is. It needs to be converted into digital form so that application and software integration could be achieved. This is achieved generally with the help of digital transformation. Successful digital transformation needs expertise, as well as skills. 

5: When the applications are present in the cloud, Is it possible to integrate them successfully with each other?

Yes, this can simply be achieved. FuseESB is known to offer favorable results in this matter. Because this approach is widely trusted, one can go ahead without worrying about anything.

6: What exactly do you know about the FuseESB approach? How is it different?

It is owned by Red Hat corporations and is basically a flexible, as well as a lightweight integration platform that businesses can consider for quick integration. It has modular integration abilities and this is exactly what makes it best in every aspect. Any form of information from different apps can easily be uncloaked when it comes to integration. 

7: What should be the features of an integration application according to you?

Depending on the need and other similar factors, any integration application has features that let it perform its task simply. A few of them are listed below.
1. It should be compatible irrespective of the technology on which the other apps need to be integrated as based.
2. It must enable organizations to monitor and control all the apps centrally.
3. The bandwidth requirement must match the organization's standards.
4. It must be free from any form of bugs.
5. The integration application should be reliable, have precision, as well accuracy.
6. It must give users access to integrate a large number of apps with each other.
7. The downtime should below.

8: Why it is necessary for businesses to connect all the information sources in the present scenario?

Currently, there are specific tasks that every team has to perform in order to run a business smoothly. There is nothing wrong to say that these tasks and processes are largely dependent on each other. A user must have all the information available to achieve a specific result. Therefore connecting the entire information source is mandatory in any business.

9: What is the Software-as-a-service approach?

It is basically the licensing and delivery model of software which is available online and users can access them based on a subscription. Software or applications in this category are centrally hosted and there is a need to have a web browser to access the same. 

10: What do you mean by the term ESB? What is its significance in data or information integration?

ESB stands for Enterprise Service Bus. This approach is useful when it comes to implementing a channel between the software applications that can easily be interacted with. It can be in any form. Sometimes there is a need to have additional tools and applications to implement this approach. If the applications are simple, they can be connected through a simple channel. However, this method has a limit and thus other approaches such as FuseESB are considered. 

11: During the integration of applications or data, what if they have different formats that are not supported by the other applications with which they need to be integrated?

This problem is common but it has a solution. The first thing a common or a standard format can be considered and all the data needs to be converted into that. It cannot be done manually as it consumes a lot of time and effort. Generally, the integration application which is considered has this ability with it. It converts all the data or information into digital formats that are generally in the form of 0’s and 1’s. 

12: Give three major reasons for application integration in a business?

1. Time and cost-saving up to a great extent.
2. While performing a specific task, users can ensure the availability of all the information and in fact, technology which assures better outcomes.
3. Reliability, efficiency, as well as enhanced productivity at the same time can be assured.

13: What is an API? 

It stands for Application Programming Interface and is basically a set of protocols and important definitions for developing specific software. It plays a significant role in the development of integration and other applications. It can also be considered as detailed information that clearly states the methods and strategies on which different software components communicate with each other. It generally includes specifications for variables, routines, remote calls, object classes, templates, data structure, and so on.

14: What are the factors that you should pay attention to before considering data or application integration?

The data should be of superior quality and is free from any form of bugs. This is necessary because later it can interrupt the functionality of apps and can even lead to providing false information which means losses. Testing the integration apps is also necessary to get the expected outcomes. 

15: How many connectors are present in the FuseESB?

FuseESB contains 150 connectors that are included in the package.

16: Give three advantages of using data or information integration applications?

There are certain advantages of using such an application. The best ones are:
1. The data or apps can be integrated with each other irrespective of their location on a network.
2. It always makes sure of multi-functionality and availability of options for performing a specific task.
3. Apps can be centrally monitored and controlled.

17: What type of integration is considered by the businesses for their applications? Temporary or permanent?

It depends on the needs actually. It is not always necessary that all the apps are to be integrated with each other all the time. Due to factors such as security and confidentiality of the information, some apps need to be run differently. However, apps with similar categories and in fact, those engaged in a similar operation can be integrated permanently.

18: How can you define enterprise application integration?

Well, it is basically a framework that generally composes of an array of services and technologies that aims to enable the process of integration of applications and systems within an enterprise. The aim is to load the data of one application with another. 

19: Can application integration be compared with automation, if so. How?

Both application integration and automation are different approaches although they seem similar. In automation, the processes are controlled and governed without a human interface which is not the case in application integration. All the sub-processes are monitored and controlled by the users in application integration. One similarity between both these approaches is they make the different applications communicate with each other but they are totally different. 

20: What type of business can consider application integration?

Almost every type of business are adopting it but the ones which are at the top are:

1. ERP systems developers
2. Business intelligence application
3. Supply chain management
4. CRM application developers
5. Human resource systems

21: What could be the consequences of lack of communication among the apps or the systems?

It can affect production, efficiency, quality, as well as collaboration up to a large extent. Much straight forwarded process can become extremely daunting. In addition to this, it can largely affect the ability of resources and an organization has to bear losses. Slow performance in every process leads to large-scale losses.

22: Can Application integration lead to automation in a business?

Yes, up to some extent it can contribute to this matter. However, alone application integration can only promote automation but couldn’t lead to the same. The business must pay special attention to keep up the pace if all they want is automation. 

23: What are the common problems that users have to face when it comes to data or application integration?

Generally, this is an error-free approach. However, the problems can declare their presence when the users make sweep changes in the application data, modify data structure or perform other similar actions. Applications must be linked based on their specifications and similarity. 

24: Can application integrations have any drawbacks associated with them, Is possible to eliminate them?

Application integration is a vast approach. It doesn’t just mean connecting the different applications with each other but its motive is to enhance efficiency in the business. The major drawback associated is a data leak. However, this can be avoided up to a great extent. Direct access must not be given to all the apps for other apps until they make a request for the same. Of course, it can avoid a lot of issues related to the same problem.

25: Name any two integration patterns that are common in application integration?

1. Meditation, also known as intra-communication
2. Federation, also known as inter-communication

26: What exactly do you know about an integration module?

There are chances that an EAI system is engaged in more than two integration operations at the same time. Every integration process is controlled by an integration module. 

27: How you can delete session logs on the IS?

These can be deleted by opening the installation folder and clicking the integration server file and then logs. All the files remain present in them with .log format. From there, any file can directly be deleted.
