What is Amazon VPC? AWS Virtual Private Cloud (VPC)

What is Amazon VPC? AWS Virtual Private Cloud (VPC) With Amazon Virtual Private Cloud (Amazon VPC), you can launch AWS resources in a logically isolated virtual network that you’ve defined. This virtual network closely resembles a traditional network that you’d operate in your own data center, with the benefits of using the scalable infrastructure of AWS.

The following diagram shows an example VPC. The VPC has one subnet in each of the Availability Zones in the Region, EC2 instances in each subnet, and an internet gateway to allow communication between the resources in your VPC and the internet.

What is Amazon VPC?

With Amazon Virtual Private Cloud (Amazon VPC), you can launch AWS resources in a logically isolated virtual network that you’ve defined. This virtual network closely resembles a traditional network that you’d operate in your own data center, with the benefits of using the scalable infrastructure of AWS.

The following is a visual representation of a VPC and its resources from the Preview pane shown when you create a VPC using the AWS Management Console. For an existing VPC, you can access this visualization on the Resource map tab. This example shows the resources that are initially selected on the Create VPC page when you choose to create the VPC plus other networking resources.

This VPC is configured with an IPv4 CIDR and an Amazon-provided IPv6 CIDR, subnets in two Availability Zones, three route tables, an internet gateway, and a gateway endpoint. Because we’ve selected the internet gateway, the visualization indicates that traffic from the public subnets is routed to the internet because the corresponding route table sends the traffic to the internet gateway.

How VPCs work: virtual networking environments

Each VPC creates an isolated virtual network environment in the AWS cloud, dedicated to your AWS account. Other AWS resources and services operate inside of VPC networks to provide cloud services.

AWS VPC will look familiar to anyone used to running a physical Data Center (DC). A VPC behaves like a traditional TCP/IP network that can be expanded and scaled as needed. However, the DC components you are used to dealing with—such as routers, switches, VLANS, etc.—do not explicitly exist in a VPC. They have been abstracted and re-engineered into cloud software.

Using VPC, you can quickly spin up a virtual network infrastructure that AWS instances can be launched into. Each VPC defines what your AWS resources need, including:

  • IP addresses
  • Subnets
  • Routing
  • Security
  • Networking functionality

Where VPCs live

All VPCs are created and exist in one—and only one—AWS region. AWS regions are geographic locations around the world where Amazon clusters its cloud data centers.

The advantage of regionalization is that a regional VPC provides network services originating from that geographical area. If you need to provide closer access for customers in another region, you can set up another VPC in that region.

This aligns nicely with the theory of AWS cloud computing where IT applications and resources are delivered through the internet on-demand and with pay-as-you-go pricing. Limiting VPC configurations to specific regions allows you to selectively provide network services where they are needed, as they are needed.

Each Amazon account can host multiple VPCs. Because VPCs are isolated from each other, you can duplicate private subnets among VPCs the same way you could use the same subnet in two different physical data centers. You can also add public IP addresses that can be used to reach VPC-launched instances from the internet.

Amazon creates one default VPC for each account, complete with:

  • Default subnets
  • Routing tables
  • Security groups
  • Network access control list

You can modify or use that VPC for your cloud configurations or you can build a new VPC and supporting services from scratch.

Amazon Virtual Private Cloud (Amazon VPC) Benefits

Firstly, Amazon VPC offers advanced security features for performing inbound and outbound filtering at the instance and subnet level. In addition, you can store data in Amazon S3 and restrict access for making it accessible from instances inside your VPC. Moreover, it includes monitoring features for performing functions like out-of-band monitoring and inline traffic inspection to screen and secure traffic.

Secondly, Amazon VPC helps you to spend less time setting up, managing, and validating. And, let you concentrate on building the applications that run in your VPCs. However, you can easily create a VPC using the AWS Management Console or Command Line Interface.

After selecting from common network setups and find the best match for your needs, VPC automatically creates the subnets, IP ranges, route tables, and security groups you need.

  • Lastly, Amazon VPC helps you in controlling your virtual networking environment by letting to,
  • Firstly, choose your own IP Address range
  • Secondly, create your own subnets
  • Lastly, configure route tables to any available gateways

If you are new to Amazon VPC then, these concepts can help you understand the key areas.

How Amazon VPC can be used to launch AWS resources?

Amazon VPC (Virtual Private Cloud) is a service that allows users to launch AWS resources in the virtual network that has been defined by the user. Logically, it is in isolation from other virtual networks that could be present in the AWS cloud. VPC can be used to launch other AWS resources such as Amazon EC2 instances. This virtual network is similar to a traditional network which the user would use in their own data centre. But VPC provides the benefits of provisioning a scalable infrastructure to use the AWS resources.

AWS Virtual Private Cloud (VPC)

The following article provides an outline for What is Amazon VPC? Amazon virtual private cloud allows you to launch AWS resources into a virtual network that is per-defined. It provides commercial cloud computing services where users can access amazon elastic compute cloud over an IP-based virtual network.

The main feature of this is the user chooses his unique IP address range, subnets, a configuration of network paths, and route cables. It is designed to give much more granular security by providing a public subnet for web servers with internet connections and make your backend database or application servers in a private subnet with no internet connection.
