The document introduces Amazon Virtual Private Cloud (VPC), highlighting its importance in security and data access within AWS. It covers key concepts such as subnets, route tables, and security measures, as well as the architecture of VPC components like gateways and access control lists. Best practices for securing and managing a VPC, including routing configuration and regular audits, are also discussed.

3. Introduction
● AWS VPC is one of the most popular and widely used services of Amazon Web Services.
● This is generally because Amazon VPC is mostly related to the security concepts in the cloud and
access to the data inside a third-party data center.
● AWS VPC is a private subsection of AWS in which you can place AWS resources such as EC2 instances
and databases.
● You have full control over who has access to the resources that you place inside the AWS Virtual
Private Cloud.

4. Key VPC Concepts
● Subnets
● CIDR Blocks
● Security Groups
● Network Access Control Lists (NACLs)
● Route Tables

5. VPC Architecture

6. ● Region: Amazon EC2 is hosted in multiple locations worldwide. These locations are composed of Regions and
Availability Zones.
● Internet gateway : It is a horizontally scaled, redundant, and highly available VPC component that allows
communication between instances in your VPC and the internet.
● Route tables : It contain a set of rules, called routes, that are used to determine where network traffic is directed. Each
subnet in your VPC must be associated with a route table; the table controls the routing for the subnet. A subnet can
only be associated with one route table at a time, but you can associate multiple subnets with the same route table.
● Network access control list (ACL) : It is an optional layer of security for your VPC that acts as a firewall for controlling
traffic in and out of one or more subnets. You might set up network ACLs with rules similar to your security groups in
order to add an additional layer of security to your VPC.
● Subnetwork or subnet : It is a logical subdivision of an IP network. The practice of dividing a network into two or more
networks is called subnetting.AWS provides two types of subnetting one is Public which allow the internet to access the
machine and another is private which is hidden from the internet.
● Instance : It is a virtual server in the AWS cloud. With Amazon EC2, you can set up and configure the operating system
and applications that run on your instance.

7. VPC Components
● Internet Gateway (IGW)
● Virtual Private Gateway (VGW)
● Peering Connections
● Elastic Load Balancers (ELBs)

8. VPC Best Practice
● Properly configure routing tables.
● Secure your VPC with Network ACLs and Security Groups.
● Use bastion hosts for secure remote access.
● Regularly audit and monitor your VPC.
