What is a VPC?
Amazon Virtual Private Cloud (VPC) is a logically isolated section of the AWS cloud where users can launch resources such as EC2 instances, databases, and load balancers. It allows users to define their IP address range, subnets, route tables, and network gateways, providing complete control over their virtual network environment.
Benefits of VPCs:
Enhanced Security: VPCs provide a secure and private environment for your resources, isolating them from other networks.
Customizable Networking: Users have granular control over IP addressing, subnets, routing, and network gateways, allowing them to tailor the network architecture to their specific needs.
Connectivity Options: VPCs offer various connectivity options, including direct connections to on-premises data centers and private connectivity through AWS Direct Connect and VPN.
Scalability and Flexibility: VPCs can be easily scaled up or down based on resource requirements, accommodating dynamic workloads and growth.
Cost Optimization: Users can optimize costs by designing the network architecture efficiently, leveraging features like subnets, route tables, and Internet Gateways.
Step-by-Step Guide to Creating a VPC in AWS:
3.1. Sign in to the AWS Management Console:
Launch your preferred web browser and go to https://console.aws.amazon.com.
Enter your login credentials to access the AWS Management Console.
3.2. Navigating to the VPC Service:
In the search bar at the top of the console, type "VPC" and select "Amazon VPC" from the dropdown results.
You will be redirected to the Amazon VPC service dashboard.
3.3. Creating a VPC:
On the Amazon VPC dashboard, click on the "Your VPCs" option in the left navigation pane.
Click on the "Create VPC" button to start creating a new VPC.
3.4. Configuring VPC Settings
Provide a name for your VPC and specify an IPv4 CIDR block (IP address range) for the VPC.
Optionally, configure additional settings such as IPv6 CIDR block, tenancy, and DNS hostname resolution.
3.5. Creating Subnets within the VPC:
Navigate to the "Subnets" section in the left navigation pane.
Click on the "Create subnet" button to create a new subnet within your VPC
.
Specify the VPC, subnet name, availability zone, and IPv4 CIDR block for the subnet.
3.6. Creating an Internet Gateway:
Go to the "Internet Gateways" section in the left navigation pane.
Click on the "Create Internet Gateway" button to create a new Internet gateway.
Provide a name for the gateway and click on the "Create" button.
3.7. Attaching the Internet Gateway to the VPC:
Select the newly created internet gateway from the list.
Click on the "Actions" button and choose "Attach to VPC".
In the attach internet gateway dialog box, select your VPC and click on the "Attach" button
.
3.8. Configuring Route Tables for Internet Connectivity:
Navigate to the "Route Tables" section in the left navigation pane.
Select the default route table associated with your VPC and click on the "Routes" tab at the bottom.
Click on the "Edit routes" button and add a new route with a destination of "0.0.0.0/0" (all IP addresses) and set the target as the internet gateway attached to your VPC.
