A stable, flexible, and secure private network space in the cloud that offers a full range of network solutions
Overview
A Virtual Private Cloud (VPC) is a logically isolated private network space on the cloud that provides network services for your cloud resources. As your dedicated network space on the cloud, your VPC can be managed as a software-defined network to implement configuration and management of IP addresses, subnets, route tables, network ACLs, and other features. VPCs also support a variety of methods to connect to the internet, such as the elastic IP and NAT gateway. You can connect a VPC to your IDC via VPN Connection or Direct Connect to flexibly create a hybrid cloud.
VPC uses mature network virtualization technology and employs various techniques such as link redundancy, multi-active/gateway primary and standby, and private network deployment across availability zones to ensure high availability of the network. Comprehensive protection of network security and stability is provided at the link level, network level, and data center level.
VPC uses the overlay technology to help you build a completely isolated private network environment. Different VPCs are 100% logically isolated from each other to meet the security isolation needs of your businesses.
VPCs provide you with a variety of ways of network access to connect your local IDC to cloud resources, such as the Direct Connect and VPN Connection.
VPC enables ultra-high-performance internet access through the NAT gateway which supports up to 10 million concurrent connections. This helps you easily break performance bottlenecks of internet access. Additionally, NAT gateways can be used with products such as elastic IP and Cloud Load Balancer for an improved business access experience.
VPC supports multi-dimensional network security control. Resource access control at the port and instance levels can be achieved through network ACLs and security groups. You can set the permission range of accounts through CAM to enhance comprehensive network security.
VPC supports visualization of network topology. Users can monitor network status in real time, set traffic alarms, and easily manage networks in a comprehensive and intelligent manner.
VPCs can be scaled elastically. You can expand your network resources flexibly as your business increases without complicated steps such as procurement, installation, and debugging. This will give impetus to your business development.
Most features of VPC are free. You can enjoy high-standard IDC-grade network resources without the need to purchase additional dedicated network devices. For optimal configurations, VPC offers a variety of flexible billing methods and packages.
VPCs can be integrated with most cloud services such as CVM, CDB, and TBDS to provide a complete cloud solution.
VPCs enable you to build a VPC-based 2-region-3-DC disaster recovery scheme that meets the security and high availability needs of in-cloud financial services.
Multiple cloud IDCs can be built and then connected to local IDCs through the Direct Connect or VPN Connection. A hybrid cloud that enables cloud-based disaster recovery and elastic business deployment can be created.
