Multinational enterprises benefits immensely by moving to the cloud. Most enterprises want to connect global offices with the HQ but building a cross-border network is very difficult, especially during the expansion period due to limited resources. Companies require a networking solution that helps them build a global network easily and cost-effectively.
Express Connect (EC) can help you build private network communication channels between VPCs or between a VPC and your local IDC. But Cloud Enterprise Network (CEN) allows you to create a global network for rapidly building a distributed business system with a hybrid cloud computing solution. In this tutorial, we will introduce how to migrate your networking services from Express Connect to Cloud Enterprise Network.
If a physical connection is established for access, no change is needed for the physical connection between your IDC and Alibaba Cloud Virtual Border Router (VBR). You simply need to change the connection mode from the VBR to the VPC instance. In this tutorial, we will introduce how to migrate to Cloud Enterprise Network offline.

This topic describes how to migrate a Virtual Border Router (VBR) that uses a peering connection to a Cloud Enterprise Network (CEN) instance. By using CEN, you can build private network communication channels between VPCs or between VPCs and on-premises data centers. CEN uses automatic route distribution and learning, which can improve the network convergence and the quality and security of cross-network communication, and achieve the interconnection of all network resources.

The procedure involved only three steps: powering on a PC, connecting its WAN port to the Internet, and connecting its LAN port to another PC. The on-site PC successfully connected to the enterprise SAP system deployed on Alibaba Cloud through the VPC without any other operations on this PC.
In addition, the network quality test results showed that the network quality of the enterprise VPC built using SmartAG was improved in aspects of delay and packet loss.
Cloud Enterprise Network (CEN) provides communication channels between cloud resources, and between cloud resources and Internet data centers (IDCs). Through automatic route distribution and learning, CEN also supports fast network convergence and high-quality cross-city communication. CEN is devoted to helping users build a globally interconnected enterprise-scale network with communication capabilities.
This tutorial outlines the necessary steps and highlights the caveats when enabling Alibaba Cloud's Cloud Enterprise Network (CEN) service to support VPN Gateways routes to either connect to an Internet data center (IDC) or another Virtual Private Cloud (VPC).
This document describes the following scenarios:
Cloud Enterprise Network provides a hybrid and distributed global network ideal for enterprise users with high demand on network coverage. With its stable transmission and next-generation network environment, the network provides high transmission speed and low latency for end-users.
Express Connect allows you to establish high bandwidth, reliable, secure, and private connections between different networks. Dedicated physical connections link your on-premise data centers with Alibaba Cloud, which improves the flexibility of your network topology and the performance of cross-network connectivity. Based on Smart Access Gateway and SD-WAN capabilities, Express Cloud Connect offers an all-in-one network service by integrating the high reliability, high performance, and low latency features of dedicated physical connections. The service also supports peering connections between VPC networks across regions and Alibaba Cloud accounts.
