VPC enables the creation of a secure and isolated network environment within Alibaba Cloud, allowing for customization of elements like IP address ranges, network segments, routing tables, and gateways. Furthermore, you can link your VPC with a traditional IDC via leased lines, VPNs, or GRE, facilitating hybrid cloud solutions. This service framework can be implemented in both on-premises and cloud-based IDCs. Various service modules are constructed on Alibaba Cloud VPC to establish completely isolated cloud environments. Interaction between on-cloud and off-cloud services occurs seamlessly over the Internet, ensuring smooth communication and integration. Such flexibility allows organizations to tailor their network configurations to meet specific operational needs.
