Google Virtual Private Cloud (VPC)
A single VPC can span multiple regions without communicating across the public internet. For on-premises, you can share a connection between VPC and on-premises resources with all regions in a single VPC. With a single VPC for an entire organization, teams can be isolated within projects, with separate billing and quotas, yet still maintain a shared private IP space and access to commonly used services. Google Cloud VPCs let you increase the IP space of any subnets without any workload shutdown or downtime. This gives you flexibility and growth options to meet your needs. VPC can automatically set up your virtual topology, configuring prefix ranges for your subnets and network policies, or you can configure your own. You can also expand CIDR ranges without downtime.

Tencent Cloud Virtual Private Cloud (VPC)
Virtual Private Cloud (VPC) helps you build an independent network space in Tencent Cloud and allows you to customize network segment classification, IP addresses, and routing policies. You can establish VPN tunnels through the public network/Direct Connect to connect the private network to other cloud resources and flexibly deploy hybrid clouds. Tencent Cloud supports VPC elastic scaling, eliminating the need to purchase, install and debug additional network devices, allowing for the flexible scaling of network resources as business scale changes and enhancing business development. You can implement resource access control at the port and instance levels through network ACLs and security groups and grant minimum account permissions through CAM to comprehensively improve your network security. Network ACL is a stateless virtual firewall that can filter selected packets and control the inbound and outbound data traffic on a subnet at the protocol and port levels.

Alibaba Virtual Private Cloud
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. 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.

Amazon Virtual Private Cloud
Amazon Virtual Private Cloud (Amazon VPC) is a service that lets you launch AWS resources in a logically isolated virtual network that you define. You have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets, and configuration of route tables and network gateways. You can use both IPv4 and IPv6 for most resources in your virtual private cloud, helping to ensure secure and easy access to resources and applications. As one of AWS's foundational services, Amazon VPC makes it easy to customize your VPC's network configuration. You can create a public-facing subnet for your web servers that have access to the internet. It also lets you place your backend systems, such as databases or application servers, in a private-facing subnet with no internet access.
