In addition to aging servers, software, and storage, some organizations may have dozens of combinations of software infrastructure stacks, multiplying the complexity and cost of maintaining the environment. It’s the complexity that occupies so much of IT staff's time, effort, and budget. For instance, labor costs climb as the number of configurations increases. You need different teams to operate, integrate, and maintain disparate infrastructures and configurations.
Standardizing on a single, modern infrastructure lets you do far more by reducing labor, maintenance, and other operating costs while freeing up staff to deliver new applications and services.
"Reduced complexity improves speed, agility, and availability. Worry less about lock-in and more about ways to accelerate orchestration and automation of IT tasks. Administration costs (not hardware or software costs) are often the biggest contributor to escalating IT operations costs."
