The Economics of Mobile and Mainframe

Tags: Proceedings, 2015, SHARE in Seattle 2015

While PC growth has considerably slowed recently, mobile adoption has taken off! There are over 6 billion mobile phones in the world today and over 30% of those are smart phones or tablets fueling the new "App Economy"! Mainframes act as system of record for over 70% of world's transactional data and hence most companies are logically seeing tremendous spikes in demand to serve the mobile channel. Caching does help reduce MIPS usage for read-only mobile workloads, but in this presentation we will demonstrate that it does not pay to build the cache, because costs are twice as much as running the mobile workloads in the existing environment leveraging the newly introduced mobile workload pricing option. Further, we will show that proactively implementing a "push" solution can save more than 50% over a "pull" based solution that causes spikes in consumption due to "sticky finger" users. We will also present a study showing over 60% higher throughput and 10% lower cost achieved by co-locating IBM MobileFirst with the back-end system of record.-David Rhoderick-IBM Corporation
