Worldwide public cloud end user spending is forecast to reach $832.1 billion in 2025, growing at a 5.9% CAGR over 2024–2028. Yet adoption is anything but uniform with 62% of organizations having migrated at least one application, while cloud costs are still the top concern for 36% of IT decision makers. Layer in the fact that cloud security services alone are projected to hit $73.2 billion in 2024 and the picture starts to look more complicated than a simple “move to cloud” decision.
