Cloud migration significantly affects IT infrastructure by transitioning data, applications, and services from on-premises systems to cloud environments. This shift leads to enhanced scalability, flexibility, and cost management, allowing organizations to adjust resources dynamically based on demand. However, it may also require a reevaluation of security protocols and reliance on third-party providers. Additionally, cloud migration can foster innovation by enabling access to advanced services such as AI and machine learning, accelerating digital transformation efforts for businesses.
