+What is a VPC?
+
+An Amazon Virtual Private Cloud (VPC) is a logically isolated section of the AWS cloud where you can launch AWS resources like EC2 instances, databases, and storage. It's essentially a private network within the AWS cloud that you have complete control over.  [AWS Training in Pune](https://www.sevenmentor.com/amazon-web-services-training-institute-in-pune.php)
+
+Key Components of a VPC:
+
+Subnet:
+
+A range of IP addresses within a VPC.   
+Can be public or private.   
+Public subnets allow instances to communicate directly with the internet.   
+Private subnets are isolated from the public internet and typically used for internal services.   
+Route Table:
+
+A set of rules that determines the path network traffic takes.   
+It specifies the destination IP address range and the target gateway or instance.   
+Internet Gateway:
+
+A gateway device that enables instances within a public subnet to communicate with the internet.   
+Network Access Control Lists (NACLs):
+
+Security layer that filters traffic at the subnet level.    [AWS Course in Pune](https://www.sevenmentor.com/amazon-web-services-training-institute-in-pune.php)
+Can be used to control inbound and outbound traffic based on IP address, port, and protocol.   
+Security Groups:
+
+Security layer that filters traffic at the instance level.   
+Can be used to control inbound and outbound traffic based on port and protocol.
+Virtual Private Gateway (VPG):
+
+Enables you to establish site-to-site VPN connections between your on-premises network and your VPC.   
+NAT Gateway:
+
+Enables instances in private subnets to access the internet without having public IP addresses.   
+Elastic IP Address:
+
+A static IP address that can be associated with an instance or a Network Load Balancer.   
+VPC Peering:
+
+Allows you to connect two VPCs, enabling private communication between instances in different VPCs.   
+Why Use a VPC?
+
+Enhanced Security: You can create highly secure environments by controlling network traffic and access.   
+Scalability: You can easily scale your VPC to accommodate growing workloads.    [AWS Classes in Pune](https://www.sevenmentor.com/amazon-web-services-training-institute-in-pune.php)
+Flexibility: You can customize your VPC to meet your specific needs.   
+Cost-Effectiveness: You can optimize resource utilization and reduce costs.   
+By understanding these core components and their interactions, you can effectively design and manage secure and scalable VPCs to meet your business requirements.
