Comparing “New Big Data” with IMS on the Mainframe

with 2 comments

While it does not come up often in today’s data management conversations, the IMS database software is at the heart of many major corporations around the world. For many people, it is the undisputed leader for mission-critical, enterprise transaction and data-serving workloads. IMS users routinely handle peaks of 100 million transactions in a day, and there are quite a few users who report more than 3,000 days without unplanned outages. That’s more than 8 years without an unplanned outage!

IBM recently announced IMS 12, claiming peak performance at a remarkable 66,000 transactions per second. The new release features improved performance and CPU efficiency for most IMS use cases, and a significant improvement in performance for certain use cases. For instance, the Fast Path Secondary Index means that workloads that use this secondary index are 60% faster.

It is interesting to compare the performance of IMS with the headline-grabbing “big data” solutions that are all the rage today. For instance, at the end of August this year, we read how Beyonce Pregnancy News Births New Twitter Record Of 8,868 Tweets Per Second. I am not saying that IMS can replace the infrastructure of Twitter. Far from it. However, I am saying that, when you consider that IMS can handle 66,000 transactions per second, the relative performance levels of the “new big data” solutions when compared with IMS are food for thought. Especially when you consider the very significant infrastructure in place at Twitter, and the staff needed to manage that infrastructure. And don’t forget that IMS supports these performance levels with full read-write capability, full data integrity, and mainframe-level security.

I appreciate that many of today’s Web-scale businesses begin with capital investments that preclude the hardware and software investments required for something like IMS. These new businesses need to be relatively agile, and depend upon the low barrier of entry that x86-based systems and open source/inexpensive software afford. However, I still think it interesting to put this “new big data” in perspective.
