N tier architecture, often referred as Multi-Tier architecture is a client-server architecture model by which developer can create flexible and reusable applications. In a simple language, Tier means layer where N-tier is nothing but an architecture model where N is inconsistent.

This software is engineered to have the application processing and the data management functions which are physically separated. This can help you in adopting new technologies and adding more components without having to rewrite the entire application, making it easier to maintain.

The N-Tier architecture divides this application into three different following tiers:

  • The Logic Tier: To perform operations in the application
  • The Presentation Tier: To view the application
  • The Data Tier: To share & retrieve the data

So let’s get in deep and know more benefits about the N-Tier architecture below:

In the present era, High-volume e-Business transactions are putting new pressures on the corporate computing environment. Functionality and stability are no longer sufficient to provide a competitive advantage. Businesses must be able to utilize and habituate applications quickly to label rising workloads and changing business needs.To improve the efficiency and the highest level of performance in the business, Data and applications must be integrated across the enterprise and to support business-critical processes.

Here are top 5 benefits to using N-tier Architecture for your software offering useful tips for creating a cost effective e-Business infrastructure:

1. Affordable Scalability & Availability

The key to E-Business scalability is that each tier can scale horizontally and the scalability of the system is enhanced since a separate connection from client is not required. This enables businesses to add computing power incrementally, using pools of affordable servers. For example, In short, If you need to add more resources, you can do it per tier, without affecting the other tiers.

2. Enhanced Security

Do you know that you can secure each of the three tiers separately using various unsimilar methods. The N-Tier architecture also takes care of the security of data, protecting the data from unauthorised access. The client will not be having the direct access to the database as the application layer is between the database layer and the presentation layer. It have the ability to provide network-wide authentication. Hence, the database will be more secured.

3. Greater Flexibility

The N-Tier application functions into three independent layers enabling easier integration. The best part is that it expands anyway according to the requirements. It has the ability to redesign existing functions for a new technology and provide access to the existing legacy information very easily and cheaply. This also provides a different transition period from the old technology to the new. The hardware and software for each of the three layers can be improved independently after the proper implementation. This split also makes it easier to integrate new applications into the environment.

4. Simplify Development 

By Inaugurating standardized hardware and software designs at each tier, Businesses can extend the benefits of the N-tier architecture even further. This series leads toward the creation of a menu of shared services that can be used in planning, designing and deploying new applications. In short, the N-Tier architecture is very friendly for development, as different teams may work on each tier without having to share resources or interfering in each other’s tasks or domains. Businesses don’t have to create these standards from the ground up. The selection and deployment of an appropriate middleware stack can provide a robust platform for both off-the-shelf and customized e-Business applications, and contribute significantly toward a more standardized and agile infrastructure.

5. Reusability and Reliability

What’s better than realising that you can reuse the existing software components which works as a key to effective use of valuable software engineering talent.  An N-Tier Architecture allows individual components to restore in case of partial service disruption being it severe or not, hence allowing shorter service recovery times.In Case, if you want to use the same program, but for a different data set, you can just reproduce the duplication of the logic and presentation tiers and then create a new data tier. Hence, Quality design of the object classes and frameworks with an eye to maximizing reuse increases the reliability of the software system.

CONCLUSION

In Today’s Era, The N-tier architecture offers best solution to the unique pressures e-Business places on corporate computing infrastructures. By splitting systems and applications into front-end, middle tier and back-end layers, the N-tier architecture supports a more standardized, building block approach to application design. In short, the N-Tier architecture helps to manage all the tiers (the logic tier, the presentation tier and the Application tier) under the same roof in an effective manner. Instead of working with several tiers its better to use as fewer tiers as possible. It is highly important to make sure that your network bandwidth and the application performance is fast and the each tier you add to your software will add a layer of complexity, higher maintenance and deployment cost. With this approach, businesses can significantly reduce their infrastructure costs to meet their most challenging performance and availability requirements. Such architectural models discover maintaining, scaling up and deploying an application on the Internet effectively.
