Virtual Private Cloud

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


Overview

Alibaba Cloud Virtual Private Cloud (VPC) is an isolated cloud network built for your exclusive use only. VPC provides you with the utmost control over data, security and resources, including configuring route tables, network gateways and selecting the range of IP addresses. You can even augment your resources by connecting your on-premise own network to Alibaba Cloud VPC and create an extension of your private cloud to develop a hybrid cloud. This also provides you with the ability to do external backups that are required by certain regulatory needs.



Product Details

Alibaba Cloud VPC allows the flexibility to build your cloud architecture in a logically isolated and secure environment. This means you can control your virtual networking environment, including the selection of your IP address range, the creation of subnets and configuration of route tables and network gateways. You can also segregate VPC instances into different security domains using security group features.

In addition, you can build layers of security into your managed private cloud network architecture. For example, you can create a public-facing subnet for your web server hosting and place your backend systems such as database or application servers in a private-facing subnet with no Internet access. Furthermore, you can launch different Alibaba Cloud products such as ECS, SLB and RDS within a VPC.

VPC supports VPN software and dedicated data line connections, as well as multi-line connections which can be connected with private, physical or other proprietary networks.



Benefits

  • Segregates VPC instances into different security domains using security group features.

  • Compliant with security isolation regulations set by the Chinese Government for financial users.


Easy Access Control

  • Easy and flexible access control solution for each security domain.

  • Quickly create and access Alibaba Cloud VPC services using the console.


Multiple Connectivity Options

  • Easily connect to the Internet by creating public-facing subnets.

  • Securely connect to your corporate data center and route all incoming and outgoing traffic of your instances.

  • Securely share resources across multiple virtual networks by connecting privately to VPCs of other Alibaba Cloud accounts.


Rich Network Connectivity

  • Supports VPN software and dedicated data line connections.

  • Supports multi-line connections which can be connected with private, physical or other proprietary network.

  • Supports VPN gateway customization. Set up your own VPN gateway or access a variety of VPN products offered on Software Marketplace.


Easy Payment Options

  • Offers flexible billing where you pay only for the resources used such as bandwidth, storage, compute, etc.



Features

Ease of Use:

Virtual LAN (VLAN)

Any broadcast domain which is partitioned and isolated in a computer network at the data link layer.

  • Alibaba Cloud uses VLAN to divide the range of private IP address into several VSwitches.

  • Helps easy deployment of applications and other VPC services.

Customize Routing Rules

  • Easily customize and manage VRouter routing rules.

  • Configure forwarding routes of traffic.

  • Define routing rules between source and destination in route tables.


Dedicated Resources:

  • Offers dedicated Elastic IP addresses (EIPs) which you can attach to the ECS instances within the managed private cloud and access them publicly.

  • Offers dedicated line access service which helps you to establish a private and direct connection from your office, local data center or co-hosting location to Alibaba Cloud data center bypassing the public Internet.

  • Dedicated line access reduces network latency and provides you with a more consistent network experience compared to other Internet connections.


Secure:

Security Groups

Security Group is a logical segregation of instances with the same security requirements and mutual trust.

  • Alibaba Cloud VPC divides ECS instances into different security domains with the help of security groups.

  • You can control network access to ECS instances using security groups.

  • Each security domain enables you to customize access-control rules for different ports and IPs.

  • Allows you to specify inbound and outbound network traffic for each ECS instance.

Network ACLs

A network access control list (ACL) is an optional layer of security that acts as a firewall for controlling traffic into and out of a subnet.

  • Operates at the subnet level which evaluates traffic entering and exiting a subnet.

  • Enables you to configure allow and deny rules.

  • Performs stateless filtering while security groups perform stateful filtering.


Hassle-free VPC Management:

  • Flexibly allocates IP addresses using CIDR (Classless Inter-Domain Routing) blocks as opposed to original allocation system based on IP address classes.

  • Replaces the old class A, B, C system and enables a single IP address to designate many unique IP addresses.

  • You can easily define traffic in route tables.


Cost-Effective Service:

  • Free components such as VSwitches, VRouter, route tables, and route entries.

  • You only pay for resources used such as ECS, RDS etc.
