Understanding the value of migrating from on-premises to AWS for application performance and security

Nucleus studied enterprise organizations’ journey to the cloud with AWS to understand how moving applications from an on-premises to public cloud environment affects the security, performance, and availability of those applications. Nucleus interviewed executives and development team leaders from 33 global enterprises spanning a wide range of industries who migrated a collective 351 applications from on-premises environments to the AWS cloud. We found that migrating to AWS substantially improves application availability, reducing both planned and unplanned downtime by 29% and 69%, respectively, and decreasing application latency by 38%. Further benefits of migrating to AWS include a reduction of IT costs, typically falling within 20 to 40 percent annually, a 55% reduction in the mean time to detection (MTTD), a 64% decrease in the mean time to resolution (MTTR), and improvements in application security, including a 43% decrease in security events.
