Virtual Private Cloud

A virtual private cloud service that provides an isolated cloud network to operate resources in a secure environment.

ConsoleContact Sales

VPC helps you build an isolated network environment based on Alibaba Cloud including customizing the IP address range, network segment, route table, and gateway. In addition, you can connect VPC and a traditional IDC through a leased line, VPN, or GRE to provide hybrid cloud services.

Features

Common Scenarios

On-cloud Intranet

Fully isolated network environment

The service system can be deployed in both local and on-cloud IDCs. Different service modules are built on Alibaba Cloud VPC to create fully isolated on-cloud environments. On-cloud and off-cloud services are interacted with each other through the Internet.

Advantages

Flexible Configuration

VPC is an SDN that enables you to customize network settings as required. Management operations take effect in real time.

Secure Isolation

VPC instances of different users are fully isolated from each other and do not share the Internet.

Integrations and Configurations

Hybrid Cloud Architecture

High-speed data interconnection on and off the cloud

An on-cloud IDC is built on Alibaba Cloud VPC and connected to the off-cloud IDC over a leased line. This protects the user's core data, perfectly copes with service surges and fast data synchronization, and implements a hybrid cloud solution.

Advantages

Enhanced Data Security

Core data is stored in the off-cloud IDC to ensure security.

Service Surge Protection

The on-cloud IDC is used to handle surge of real-time service access.

Fast Data Synchronization

By using leased lines, on-cloud and off-cloud data can be fast synchronized in batches.

External Service Provision

Multiple services share Internet bandwidth

If you create multiple applications based on Alibaba Cloud VPC, where each application must provide external services and their traffic fluctuations are inconsistent, you can share bandwidth among multiple IP addresses to minimize the effect of these fluctuations and reduce costs.

Advantages

External Service Provisioning

Port mapping and IP address mapping are provided, allowing VPC ECS instances to provide external services.

Low-cost

Multiple VPC ECS instances can share Internet bandwidth to optimize costs.

High-performance

NAT Gateway provides the large-bandwidth throughput and a large number of connections.

Proactive Internet Access

Flexible Internet access for multiple VPC ECS instances

If you create on-cloud interactive modules on VPC and deploy other systems in multiple off-cloud physical IDCs, the on-cloud VPC ECS instances must be able to proactively access the Internet to synchronize content processed on the cloud to the off-cloud IDCs, providing users with reliable HD video services.

Advantages

Easy to Configure

Multiple VPC ECS instances can use the SNAT function to proactively access the Internet, ensuring convenient management.

Security

VPC ECS instances do not need their own public IP addresses, avoiding management hassles and security risks.

Multi-region High-speed Interconnection

Widely spread services and high-speed data interconnection

On-cloud services can be built fully based on VPC with users spread across all regions. To speed up user access, networks of the service systems in different nodes must be interconnected with each other at high speed.

Advantages

Secure Isolation

Services are deployed on Alibaba Cloud VPC, which is secure and reliable.

High Reliability

Express Connect is used to connect different VPC instances, ensuring the quality of cross-region interconnection.

High Reliability

VPC with Express Connect provides the maximum interconnection bandwidth of 10 Gbit/s, easily meeting the needs of massive applications.
