Mainframe systems are known for powering through vast amounts of data. In fact, the IBM z15 can handle 19 billion encrypted transactions in a single day, at a rate of approximately 220,000 per second.

But the trend towards digital transformation has many enterprises reevaluating their mainframe systems, and the increased load on IT infrastructures in response to the COVID-19 pandemic has only accelerated these demands.
