AWS has designed a new method of creating VPC for ease of use. The changes include a new visualization of the resources. In this method of creating VPC, we can see all components of VPC in a single frame as one project with VPC, subnets, route tables, VPC endpoints, internet gateways, and NAT (Network Address Translation) gateway.
This is an extremely useful approach to launching the VPC with its components in one go. In this blog post, I have tried to illustrate this new process of creating VPC with a step-by-step illustration.
Here is the preview:
New AWS VPC Benefits
A wide array of benefits is offered by AWS VPC. Salient ones include:
It provides an isolated environment inside AWS to launch your instances.
Offers a virtual network to define rules and policies for your services.
Functions as a security wall that allows you to control which portion of the infrastructure has to be exposed to the external world.
Provision setting up subnets, IP ranges, and network configurations based on your preferences.
Ensure database and application servers are accessible only to instances acting as web servers inside your AWS.
Functions as a software firewall that authorizes the inbound and outbound traffic from your instances.
AWS VPC: Scenario-based Use Cases
VPC is a software-defined network that provides design flexibility and can integrate and secure the resources available on the AWS cloud. Important use cases include:
Hosting a Public-Facing Website
AWS VPC can be used to build a single-tier web application or a simple website. You can secure the website through instance-level firewalls, called security groups, and regulate the inbound and outbound traffic to the internet (either HTTP or HTTPS traffic).
Hosting Multi-Tier Web Application
If you are planning to host multi-tier web applications then ensuring strict access control and more restrictions for communication between web servers, app servers, and database servers are critical. VPC is an ideal solution for multi-tier web application hosting as it comprises built-in functionalities.
Creating Branch Office and Business Unit Networks
Connecting branch offices with their own interconnected networks is a common requirement for many organizations. VPC provisions this requirement with a separate subnet for different branch offices. By default, all resources within a VPC can communicate with each other with private IP addresses thus enabling the offices to be connected to each other with their own local network within their own subnet.
Extending Corporate Network in AWS Cloud
Provided you have exhausted all data center resources and need to add resources such as compute, storage, or database then you can extend your corporate networking resources in the AWS cloud and reap the benefits of cloud computing features such as elasticity, pay-as-you-go model, high availability, security, etc.
Step by Step Guide to Creating VPC with New Method
2. After clicking on Create VPC, we get two options ‘VPC only’ and ‘VPC subnets etc.’ We have to choose the option VPC subnets etc. to create the VPC using the new method.
3. There is a Name-tag auto-generation feature: Enter a value for the Name-tag. This value will be used to auto-generate Name tags for all resources in the VPC.
4. Availability Zones: We can select the multiple numbers of availability zones we want for the network setup and to achieve high availability.
5. Public Subnets:
6. Private Subnets:
7. NAT Gateways DNS options and VPC Endpoints: Endpoints can help reduce NAT gateway charges and improve security by accessing S3 directly from the VPC. By default, full access policy is used. You can customize this policy at any time.
This new method of creating AWS VPC can save a lot of time and effort to set up the VPC and its components with auto-generated name tagging for all subnets and other VPC resources. In this blog post, I have tried to give a pictorial view of our complete network setup.

1. What is Amazon Virtual Private Cloud?
Amazon VPC helps to create a logically isolated section of the Amazon Web Services (AWS) cloud so that you can launch AWS resources in a virtual network defined by you. With Amazon VPC you have complete control over your virtual networking environment, selection of your own IP address ranges, creation of subnets, and configuration of route tables and network gateways.
2. Why should I use Amazon VPC?
Amazon VPC helps you to build a virtual network in the AWS cloud, further it requires no VPNs, hardware, or physical datacenters. Also, with AWS VPC you can define your own network space, and control the way network and the Amazon EC2 resources inside your network are exposed to the Internet.
