Overview of Virtual Private Cloud (VPC)
Alibaba Cloud's Virtual Private Cloud (VPC) service offers a secure and isolated cloud network environment for operating resources with enhanced security measures. By customizing IP address ranges, network segments, route tables, and gateways, users can create a tailored network setup to meet their specific requirements. Additionally, VPC enables the connection between Alibaba Cloud and traditional on-premises data centers (IDCs) via leased lines, VPNs, or GRE, facilitating hybrid cloud services.
Key Benefits of Alibaba Cloud VPC
1. Secure Isolation: VPC establishes an isolated network environment on Alibaba Cloud, achieving layer-2 logical isolation between different VPC instances, enhancing security.
2. Flexibility: Software-Defined Networking (SDN) allows users to configure networks based on their needs, customize IP address ranges, and manage route tables, ensuring flexibility in network operations.
3. Scalability: Compatible with multiple products, VPC seamlessly integrates with various services and facilitates Internet portal management to support hybrid cloud architectures.
4. Free of Charge: Alibaba Cloud offers a fully isolated VPC environment at no additional cost, providing users with a cost-effective solution.
