Amazon Virtual Private Cloud (VPC) allows the users to use AWS resources in a virtual network. The users can customize their virtual networking environment as they like, such as selecting own IP address range, creating subnets, and configuring route tables and network gateways.

The list of AWS services that can be used with Amazon VPC are −

Amazon EC2
Amazon Route 53
Amazon WorkSpaces
Auto Scaling
Elastic Load Balancing
AWS Data Pipeline
Elastic Beanstalk
Amazon Elastic Cache
Amazon EMR
Amazon OpsWorks

Features of VPC

Many connectivity options − There are various connectivity options that exist in Amazon VPC.
- - Connect VPC directly to the Internet via public subnets.
  - Connect to the Internet using Network Address Translation via private subnets.
  - Connect securely to your corporate datacenter via encrypted IPsec hardware VPN connection.
  - Connect privately to other VPCs in which we can share resources across multiple virtual networks through AWS account.
  - Connect to Amazon S3 without using an internet gateway and have good control over S3 buckets, its user requests, groups, etc.
  - Combine connection of VPC and datacenter is possible by configuring Amazon VPC route tables to direct all traffic to its destination.

Easy to use − Ease of creating a VPC in very simple steps by selecting network set-ups as per requirement. Click “Start VPC Wizard”, then Subnets, IP ranges, route tables, and security groups will be automatically created.
Easy to backup data − Periodically backup data from the datacenter into Amazon EC2 instances by using Amazon EBS volumes.
Easy to extend network using Cloud − Move applications, launch additional web servers and increase storage capacity by connecting it to a VPC.
