Inflexible infrastructure

Modernizing apps with legacy edge delivery services moves app services to the cloud — but creates fragmented networks that hamper business and developer agility.

AI management overhead

Modernizing apps with hyperscalers means gaining AI’s business value — but also having to manage its infrastructure headaches.

Cloud lock-in

Modernizing apps with hyperscalers can accelerate cloud migration—while locking you into one cloud, increasing risks and costs, and reducing flexibility.
