e-Hr Solution has been designed to generate, manage and look after the Customer requirement, for this business need, we design the solution with following approach.

Approach is to create a single instance of web server in cluster mode, Single instance of application server in High availability mode with the single data base server in clustered mode, There are separate instance of the data base instance created on same DB server as per bank requirement. When the approx. 10,000 employee access to the application, request lands on web server identified the Application server instance and redirect the request appropriate instance of the application

The advantage of a single instance is that

• It uses less resource to server the same requests as multiple instances
• quite simplified and easily manageable
• Reduced hardware cost
• Reduced resource consumption
• Reduced maintenance
• Reduced physical space requirement
• Application is deployed at single place, all instance are linked with same binaries , only configurations are different for each instances
• HTTP based routing decisions built using rules that examine HTTP request information
• Management and monitoring of all configuration settings and aggregated runtime statistics through IIS Manager interface
• Intelligent live request routing
  for redirect the request our approach is use to the ARR algorithm. The purpose is to attain optimal resource utilization, maximize request throughput, minimize response time, and avoid server overload

Application Request Routing (ARR) is a proxy-based routing module that uses HTTP headers, server variables, and load balance algorithms to determine how to forward requests to content servers. ARR leverages the URL Rewrite module to incoming requests which comes from RRBs web browser

ARR is able to cache on disk any HTTP traffic that passes through the server. By combining the disk caching capabilities along with a hierarchy of IIS Web servers running ARR

The solution consist of following major parts

• Private cloud ( Intranet Zone)
• Internet cloud (Employee using HRMS application through public network)
• Firewall and routers
• DMZ (consist of web server in load balance mode)
• Militarized Zone

2) E Hr uses two key strategic enabling technologies that substantially improve the effectiveness of reporting solutions and enable institutions to achieve better results for senior management and employees

OLAP Technology – providing speed, easy to use and powerful analytics. Data is load with the various data transformation algorithm in the cube for showing the instantly data. Data cleaning is also applied on various attribute like Gender, special category etc., and gender the various MIS Reports for management purpose.

Dashboards – providing intuitive and simple access to key performance indicators, Scorecards, trends and key management information. Various dash boards like No of leaves ,Claim ,Travel etc. pending show on the employee login ,

In the manual system for pay the employee salary bank people post the one by one voucher or give the cheque for all employee it is very time consuming process, to overcome this problem, E Hr Solution offer the text file for region wise, branch wise, Head office wise which is instantly post the salary on the salary accounts, apart from the salary E Hr also post the every claim amount which was approved by the management is post the employee account.

• Reduce technical complexities related to data
• Single port enabled
• Reduce the manual work
