HDFC Bank about their DBaaS Implementation in India

HDFC Bank in India (2nd largest private sector bank) went live recently on a combination of Exadata and Enterprise Manager 12c, to run their internal Databases as a Service (DBaaS) cloud. They were very successful in this venture and presented on the same at the recent Oracle Open World (OOW). You can download their very interesting presentation from either of the following links:


The presentation speaks for itself. One of the main reasons for them to go the DBaaS way, was to increase business agility and the presentation is very effective in establishing the DBaaS solution as crucial to their agility. The drivers for DBaaS for them were:

- the need to be more agile as the business wants to launch new schemes all the time which require some changes to the DB / Application.

- each time they have to launch such a scheme, they have to create a copy of the DB and test the changes

- this takes time because setting up a DB from scratch takes some effort (not to mention expensive third-party SI resources which get charged to the bank of course, and human errors which can delay the test)

- this is a dynamic market where even a few days make a big difference so time to market is crucial

- such companies need a solution to provision databases on demand automatically for testing changes in the shortest possible time.

The Oracle DBaaS solution helps them cut the time from 56 days (if testing hardware is not ready available. It is 3.5 days even if h/w is available) to 3 hrs. This solution therefore saves critical Go To Market time in addition to reducing third-party SI costs, and improving hardware utilization. They have used the Cloud Management pack in EM12c to manage the DBaaS in addition to tracking usage by each department so that they can be charged for the use of the same.

This is a story that would impress most large companies that have a large number of databases and have to make frequent changes to them to be more agile. Let me know if you want more details.

I am pleased to say that 6 years ago, I had introduced Enterprise Manager 10g Grid Control to the DBA team in HDFC Bank to set up their RMAN backups, and also demonstrated cloning of databases to them using Grid Control. Nilanjay of HDFC bank has graciously acknowledged that their Enterprise Manager journey started with me, all triggered post working with me 5-6 years back. Thanks Nilanjay for your graciousness.
