Deployment
The following diagram illustrates the deployment of the web application

The Deployment of the migrated web application requires the following environments.

Browser - Client Browser to view the HTML pages for data input and view

Web Servers - Deploy HTML/JSP pages to Web server. The web server serves the request from client browser and sends request to application data for data retrieval, validation and updation. Then it returns the generated html from the application server to the client browser.

Application Server - The application server processes the request from the client and does the validation, data retrieval and updation. The server generates the dynamic web pages from the data retrieved in the datastore.

Database - The database server is for storing the data created from various sources. Later on, it helps to retrieve and update.

PDF Viewer - The PDF viewer in the browser client helps to view the reports generated from the application server in a PDF format.

PSR Viewer - The PSR viewer in the browser client is to view the reports generated from the application server as a PSR format.

Excel - Excel is part of Microsoft Office. This helps viewing the text data downloaded from the application server for data manipulations or reports.
