AWS VPC

AWS VPC

Amazon Virtual Private Cloud (Amazon VPC) is a virtual network service provided by Amazon Web Services (AWS) that enables users to launch AWS resources into a virtual network that they have defined. This allows users to have complete control over their virtual networking environment, including the ability to create subnets, configure security groups, and assign IP addresses. 
One of the key benefits of using Amazon VPC is the ability to extend your own on-premises data centre into the cloud. This allows you to seamlessly connect your existing infrastructure with AWS resources, enabling you to leverage the scalability and flexibility of the cloud while maintaining control over your data and network security. 


Another benefit of Amazon VPC is the ability to isolate your resources from other users on the same physical infrastructure. Each Amazon VPC is logically isolated from other virtual networks in the AWS Cloud, allowing you to create a virtual network that is completely separate from other networks. This can be particularly useful for security and compliance purposes, as it allows you to create a secure and isolated environment for your resources.


In addition to creating and configuring your own virtual network, Amazon VPC also provides a range of networking services that can be used to connect your resources. 
These services include :

  • Virtual Private Network (VPN) connections: Allows you to create a secure, encrypted connection between your on-premises data centre and your Amazon VPC. 
  •  Direct Connect: This enables you to establish a dedicated network connection between your on-premises data centre and your Amazon VPC. 
  • Elastic IP addresses: Allows you to allocate a static IP address to your Amazon VPC, which can be used to connect to your resources from the internet.
  • Gateway: Provides a connection between your Amazon VPC and the internet. 

Overall, Amazon VPC is a powerful and flexible service that provides a range of options for creating and managing your own virtual network in the cloud. Whether you want to extend your on-premises data centre into the cloud, create a secure and isolated environment for your resources, or simply need a way to connect your resources to the internet, Amazon VPC has you covered. 

Creating your own VPC 

To create a virtual private cloud (VPC) in Amazon Web Services (AWS), you can follow these steps: 

1. Sign in to the AWS Management Console and navigate to the Amazon VPC dashboard. 
2. To start the creation process click the "Create VPC" button 
3. Enter a name and a CIDR block for your VPC. The CIDR block defines the range of IP addresses that will be available to your VPC. 
4. Select whether you want to enable Amazon Elastic Container Service for Kubernetes (EKS) for your VPC. EKS is a service that allows you to run Kubernetes clusters on AWS. 
5. Now to create your VPC click the "Create VPC" button. 
6. Once your VPC has been created, you can create subnets within it. To do this, click the "Subnets" link in the left-hand menu and then click the "Create Subnet" button.
7. Enter a name and a CIDR block for your subnet, and select the VPC and availability zone in which you want to create it. 
8. Click the "Create Subnet" button to create your subnet. 
9. Repeat this process to create additional subnets as needed. 
10.Once your subnets have been created, you can launch resources such as EC2 instances, RDS databases, and more into your VPC. 

By following these steps, you can create your own VPC and customize it to meet the needs of your application or workload. 

Custom VPC: 

A custom Virtual Private Cloud (VPC) in Amazon Web Services (AWS) is a virtual network that you create and configure to meet the specific needs of your application or workload. With a custom VPC, you have complete control over the IP address range, subnets, and network gateways for your virtual network. 


A custom VPC allows you to create a virtual network that is logically isolated from other virtual networks in the AWS Cloud. This can be particularly useful for security and compliance purposes, as it allows you to create a secure and isolated environment for your resources.
