VMware and HDFC: Collaboration to transform and expand banking facilities

By

Well known Indian mortgage service provider Housing Development Finance Corporation (HDFC) Bank that now offers a wide range of banking facilities, had to manage and maintain 900 physical servers across India besides supplying additional servers at its primary datacenter in 2008. Following the surging demand of banking service from 4 crore rural and regional customers in India, HDFC’s IT team in India deployed a manageable virtual server from VMware to rapidly scale its datacenter resources and minimize its total cost of ownership. HDFC’s Vice President-G S V Surya and his team wanted to run an application in virtual machine in the datacenter from its each branch rather than running its core application on a physical server at its each branch.

The Solution:
Due to increasing burden of managing data, the Bank in 2009 replaced its old physical server of its banking solutions and started the new core banking system by embedding virtual servers. After installation, HDFC bank in 2012 was able to manage 2,300 VMware vSphere virtual machines on 170 physical servers; and out of these 1,300 virtual machines was used to provide branches with the old and new banking systems. Apparently, these virtual machines have delivered HDFC Bank to process all transactions and customer service smoothly.
Hence, the solution offered by VMware has enabled HDFC Bank to cut total cost of ownership by around 30 percent, which has also reduced the datacenter space, in addition to this all resources for new branches was provisioned in seven to ten days. The solution by VMware offered interactive monitoring tools displaying resources and usage rates for each machine.
"The virtualized infrastructure has given us the agility to launch new products and services ahead of the market," says VP of HDFC Bank, G S V Surya. The bank is currently taking the advantage of balancing the workloads across the virtualized cluster while maximizing the performance overall. This virtualized infrastructure is currently catering to multiple branches across India.

Profit and Productivity in Business:
After moving to virtualized infrastructure across India, the bank then opened more 1,700 branches, out of which 1,300 relied on virtual machines between 2008 and 2012. Due to this, the bank has touched over million rural people in India which has enabled them to avail numerous banking products and benefits.
But previously, the bank had to send a local IT technician to fix issues, but can now easily manipulate using virtual machine. This has eased the maintenance load on IT team.
Moreover, after installing VMware’s solution, bank’s average server CPU usage has also surged from 15 percent to 80 percent, ensuring guaranteed ROI in addition to energy saving. “Most importantly, the flexible infrastructure has given us great agility - we can now launch new products and services ahead of the market.” strengthening our competitiveness.” concludes Surya Prasad.
