Cloud Services
Cloud services refer to the delivery of computing resources—such as servers, storage, databases, networking, software, and analytics—over the internet (“the cloud”) rather than through on-premises infrastructure. They provide flexibility, scalability, and cost-efficiency for businesses of all sizes.
