AWS Virtual Private Cloud

AWS Virtual Private Cloud (Amazon VPC): The Virtual Private cloud of Amazon allows the client to provide an isolated part of the Amazon Web Services cloud, where the client can launch and run various Amazon resources in a user-defined virtual network.

In the virtual private cloud, the client has absolute control over the networking environment contained within, including but not limited to defining the range of the network IP address, subnet creation, and route table and network gateway configuration.

Both IPv4 and IPv6 can be used in the virtual private cloud for more secure and easier access to various resources and programs the user may require. The client can easily configure the network as they wish for their virtual private cloud.

For example, the client may choose to create a subnet that is public-facing for their web server instances that have access to the internet as a whole but can keep their backend systems, their servers, and databases in a private subnet, with no internet access, in order to maintain security and control.



Multiple layers of security can be leveraged in order to help control access to EC2 server instances in various subnets. The client can also create a hardware-based virtual private network in order to facilitate a connection between their own data center and their virtual private cloud, and use the Amazon Web Services Cloud as an extension of their own data center.

AWS Virtual Private Cloud Benefits

Simple

The Amazon Management Console helps to create Amazon VPC quickly and simple. For that, you need to select from common network setups to find the best match as per you needed. The IP ranges, subnets, security groups, and route tables are automatically created. So that you can spend more time on building your application rather than setting up and managing.

Customizable

If required you can control your virtual networking environment that includes selecting your own IP address range, subnets creations, network gateways, and route table configuration. You can also customize the network configuration by creating public-facing subnets that have access to the internet. The private facing subnet which has no internet access specifies backend systems like databases or application servers.

Secure

The AWS Virtual Private Cloud defines the advanced security features like security groups and network access that enables inbound and outbound filters at the instance and subnet level. You can also store data in Amazon S3 and make authenticated access inside your Virtual Private Cloud  (VPC). To get additional security, you can create a dedicated instance that can be isolated from other AWS Accounts at the hardware level.
