Cloud infrastructure supports software development by providing scalable resources, enabling rapid deployment, and offering collaborative tools. It allows developers to access virtual machines, storage, and databases on-demand, reducing the need for extensive physical hardware investments. This scalability ensures that organizations can adjust resources to meet variable workloads efficiently. Additionally, cloud platforms offer development frameworks and services that facilitate continuous integration and continuous deployment (CI/CD), accelerating the software delivery process. By supporting collaboration, cloud infrastructure enhances team productivity, enabling developers to work remotely and iterate more quickly, ultimately leading to faster innovation cycles and improved software quality.
