This API is applicable for providing multi-site, multi-cloud network connection for customers, and provide virtual private network services for industries and applications such as education, medical, Internet of Things (IoT), cloud desktop, cloud conference, cloud recording and etc. For example, the first use case is a digital exhibition application that needs to render a digital model in the central cloud and use the rendering model in the edge cloud. The digital exhibition application deployed in local site subscribes the Site To Cloud VPN API service between local site and edge cloud, thus the customers to the digital exhibition hall in the local site can access rendering application with large bandwidth and will enjoy good experience. The second use case is for cloud court application which requires secure and large bandwidth to deliver trial video materials to the central cloud since these video materials need to be stored for a long time, so cloud court application is suitable to call the Site To Cloud VPN API to achieve elastic, private and secure data delivery and storage.

• Easy use/invocation: The Site To Cloud VPN API enables users to create and configure site – to – cloud network services with just one click, which significantly reduces the operation complexity and saves time.
• Fast service provisioning: When users demand non – public cloud leased network services with certain SLA requirements, telecom operators can quickly set up the service by coordinating the IP VPN connections of relevant networks, ensuring rapid service deployment.
• Flexibly expanded connection of customers’ branch sites: This API offers great flexibility in expanding customers’ branch – site connections. It supports multi – site and multi – cloud network connections, allowing enterprises to easily add new branches or upgrade network bandwidth as needed.
