Digital transformation is the main driver for global enterprises. According to software company ServiceNow, businesses will spend a staggering $7.4 trillion on digital transformation during the next three years. A key reason is that larger enterprises need to remain competitive and relevant. Otherwise, relentless disruption will occur.

Many of these transactions are mission-critical, such as those for banking, insurance, and energy.
