In a cloud environment, the Virtual Private Cloud (VPC) is the backbone that connects your resources to the Internet. A VPC is a logically isolated network within Amazon Web Services (AWS), allowing you to launch Amazon Elastic Compute Cloud (EC2) instances, Amazon Relational Database Service instances, and other Amazon Web Services resources in a virtual network. By default, your VPC is created without any internet connectivity. This means that the resources launched in the VPC do not have access to the internet.<\/p>\n
In this tutorial, you will learn how to connect your VPC to the Internet using NAT Gateway. NAT Gateway is a highly available AWS managed service that makes it easy to enable Internet access for your instances within your VPC. With NAT Gateway, your instances remain private, and only the traffic that you choose is routed through the Internet Gateway.<\/p>\n
Before we get started, you need to ensure that you have the following:<\/p>\n
The first step involves creating a VPC. Follow the steps below to create a VPC:<\/p>\n
After creating your VPC, the next step is to create subnets. A subnet is a range of IP addresses in your VPC. AWS recommends that you create at least two subnets in each Availability Zone (AZ) to provide high availability and fault tolerance for your resources.<\/p>\n
Follow the steps below to create two subnets:<\/p>\n
Follow the same steps to create a private subnet. However, use a different CIDR block for the private subnet (e.g., 10.0.2.0\/24).<\/p>\n
The next step is to create an Internet Gateway (IGW). An IGW is a horizontally scaled, redundant, and highly available virtual appliance that allows communication between instances in your VPC and the internet.<\/p>\n
Follow the steps below to create an IGW:<\/p>\n
The next step is to create a NAT Gateway. NAT Gateway is a highly available AWS managed service that makes it easy to enable Internet access for your instances within your VPC.<\/p>\n
Follow the steps below to create a NAT Gateway:<\/p>\n
After creating a NAT Gateway, the next step is to update the route tables for your subnets. A route table contains a set of rules, called routes, that determines where network traffic is directed.<\/p>\n
Follow the steps below to update the route tables:<\/p>\n
Follow the same steps to update the route table for your private subnet. However, use a different target for the private subnet – a network interface of a NAT Gateway.<\/p>\n
Now that you have completed the necessary configurations, it’s time to test connectivity between your instances and the internet.<\/p>\n
Follow the steps below to test connectivity:<\/p>\n
sudo yum install httpd -y\n<\/code><\/pre>\n\n- Start the Apache Web Server by running the following command:<\/li>\n<\/ol>\n
sudo service httpd start\n<\/code><\/pre>\n\n- In your web browser, enter the public IP address of your NAT Gateway. You should see the Apache default page.<\/li>\n<\/ol>\n
Congratulations! You have successfully connected your VPC to the internet using NAT Gateway.<\/p>\n
