Description

FIELD OF TECHNOLOGY

Embodiments of the present invention relate to the field of computer applications. More particularly, embodiments of the present invention relate to scalability of n-tier computer applications.

BACKGROUND

Existing, n-tier computer application infrastructures typically consist of logical blocks that are, referred to as interface, application server, data store, and the like. Generally, all these blocks are tightly coupled together in the n-tier computer application infrastructures. However, with the existing n-tier computer application infrastructures, it is difficult and cumbersome to scale an n-tier computer application to support as the users, transactions and/or complexity increases over time as the volume of the user base increases, the number of transactions grows, and/or the complexity significantly increases. While the n-tier computer application can use more powerful machines to scale (referred to as ‘Vertical Scaling’), there is a natural limit to the power of the machine that can be used. Furthermore, the cost of upgrading the machines can be significant. Another existing technique to scale is by adding more machines and computing power, especially at the bottleneck areas of the n-tier computer application. This is referred to as ‘Horizontal Scaling’. However, the existing n-tier computer application infrastructures require considerable software development effort and time to rewrite the n-tier computer application to scale to support these Horizontal Scaling efforts. The reason being, that one has to read and understand the current code in the n-tier computer application and then rewrite the code in the application and may also require changing the computer application architecture to provide the needed horizontal scalability, which can require significant software development effort and time. Further, this development effort may need to be repeated as and when new functionalities are added, which requires scaling as well.

DETAILED DESCRIPTION

A system and method for providing automatic scalability for n-tier computer application infrastructure is disclosed. In the following detailed description of the embodiments of the invention, reference is made to the accompanying drawings that form a part hereof, and in which are shown, by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

The term “web service” refers to an application that can be accessed over a network, such as IP network. The web service receives inputs, conducts operations and computations as needed and returns the results. The web service is not restricted to any particular machine and can be located anywhere as long as it can be accessed via the network.

The term “web application” is considered to be a collection of one or more “web services”. The term “n-tier” refers to greater than or equal to one tier. The term “refactoring” refers to the web services, such as rewriting services, joining services and/or separating services.

The present invention automatically decouples, service enables and scales a tightly coupled n-tier computer application infrastructure based on policy control, self-correcting scheme, computer application usage and the like to adopt itself based on user base needs. The present invention provides automatic scalability for n-tier computer application infrastructure.

FIG. 1 is a block diagram 100 illustrating an n-tier computer application infrastructure 110, in the context of the invention. Particularly, the n-tier computer application infrastructure 110 includes an interface 120, an application server 130 and a data store 140. The application server 130 further includes an n-tier computer application. The interface 120 may include a web page, which allows a user to interact, enter data or queries, edit data and perform similar actions on the n-tier computer application. The application server 130 processes the data entered by the user via the interface 120. The data store 140 stores any data associated with the n-tier computer application.

The operation of the above n-tier computer application infrastructure 110 is described, for example, using a billing application of a consulting company for keeping track of the payments. For example, a vendor enters the name of a customer, number of hours spent with the customer, the hourly rate for the customer, the due date and the current status (sent, overdue, paid) of the payments and so on using the interface 120. The application server 130 then collects the information provided by the vendor, calculates the total payment due, stores the information and the calculated payment due in the data store 140 and generates a printable invoice. The data store 140 may also include a procedure to check the due date of each payment every morning, and creates a list of overdue invoices.

FIG. 2 illustrates a system view 200 of the n-tier computer application infrastructure 110 (also shown in FIG. 1) connected to a remote server 210 via an IP network 260, according to one embodiment. Further, the remote server 210 includes a cloud engine 220. The cloud engine 220 further includes a code analyzer 230, a data store refactoring engine 240 and a service factory 250.

Further, the cloud engine 220 also identifies major database aspects of the data store 140 and generates a reconfigured automatically scalable n-tier computer application infrastructure that is horizontally and vertically scalable based on the identified major functional aspects and the major database aspects.

In operation, the code analyzer 230 analyzes the n-tier computer application to identify major functional aspects of the n-tier computer application residing in the n-tier computer application infrastructure 110. In one embodiment, the code analyzer 230 identifies the major functional aspects of the n-tier computer application by analyzing code of the n-tier computer application. Exemplary major functional aspects can be bottle necks associated with most used parts of the code in the n-tier computer application and the like.

Exemplary major database aspects can be bottle necks associated with most used parts of the data store 140 in the n-tier computer application infrastructure 110 and the like.

Furthermore, the service factory 250 generates a reconfigured automatically scalable n-tier computer application infrastructure that is horizontally and vertically scalable based on the identified major functional aspects, the identified major database aspects and the n-tier computer application usage needs.

Further, the data store refactoring engine 240 may analyze the data store 140 to identify the major database aspects, such as storing the actual data such as the invoice data and invoice value, running a daily process to check for overdue payments, generating a list of overdue payments every day, providing a list of existing invoices as requested and the like. Furthermore, the service factory 250 may generate services for reconfiguring automatically scalable n-tier computer application infrastructure using the above identified major functional aspects and the major database aspects.
