What is cloud calculation?

Cloud computing is a computing mode that can obtain highly available computing resources anytime and anywhere through the network. Cloud calculation virtualised hardware and software resources to turn primary resources into scalable "pools". Therefore, cloud providers can implement the fair allocation of resources and provide pay-as-you-go services; customers can adjust the required resources according to business needs. Cloud service providers can also efficiently allocate their resources to reduce service costs and provide users with computing, storage, and data business support through different service models.
