Cloud computing eliminates several traditional IT infrastructure challenges, notably the need for hardware purchase and maintenance, capacity planning, and scalability limitations. Instead of relying on physical servers, organizations leverage virtualized resources hosted in data centers. This model transforms capital expenses into operational expenses, allowing for more efficient resource allocation. Additionally, cloud services enable rapid deployment and scaling of applications, facilitating agility and flexibility. Overall, cloud computing streamlines IT management, reduces costs, and enhances organizational responsiveness to changing demands.
