AWS MasterClass: Networking & Virtual Private Cloud (VPC)

Learn the AWS VPC fundamentals, including subnets, route tables, security groups, and ACLs, and how private and public subnets, peering, and internet gateways enable secure cloud networking.

Explore subnets, route tables, and VPC peering in AWS, learning how subnets span availability zones, how auto assigned public IPs work, and how routing connects VPCs across accounts.

Explore AWS VPC components, including VPC peering use cases, network ACLs, security groups, VPN connections, and Internet gateways, to connect resources across accounts and central VPCs.

Describe how an internet gateway routes external traffic to resources inside the AWOS VPC and how elastic IPs provide static public addresses attached to a network interface for quick failover.

Explore AWS subnets in a VPC, including public, private, and VPN-only types, their routing to internet gateways or virtual private gateways, and the role of security groups and NACLs.

Explore how security groups attach to EC2 instances and network ACLs bind to subnets in an AWS VPC, delivering a double layer of security with subnet allow and deny rules.

Compare default and non-default AWS VPCs, detailing preconfigured components like default subnets, internet gateway, route table, and security groups, and the manual setup required to enable internet access.

Compare the default VPC with a non-default VPC to see how AWS auto-configures networking, internet gateways, and subnets, while non-default VPCs require manual CIDR, routes, and security groups.

Learn how default VPC provides a default internet gateway and auto assigned public IPs for EC2, while non-default VPCs require subnet, route table, and elastic IP configurations for internet access.

Learn to provision an EC2 instance in a non-default VPC, configure routing tables and internet gateways, and set security groups for SSH access.

Configure NACLs attached to subnets and security groups attached to instances to secure traffic in the non-default VPC.

Learn to create a non-default VPC from scratch in the VPC dashboard, configure public, private, and VPN subnets, and connect them with internet gateways and route tables.

Create subnets in the Vpc with non overlapping cidr blocks across availability zones, then review route tables and subnet associations to enable internal communication while enforcing security groups.

Set up subnets in a non-default VPC by attaching an internet gateway, updating route tables for public and private subnets, and configuring a VPN subnet with a virtual private gateway.

Discover how nat enables internet access for private subnets in aws vpc, using nat gateway or nat instance, and how it masks ip addresses to improve security.

Create a dedicated VPC, add public and private subnets, attach an internet gateway, configure public routes, launch EC2 instances (one public, one private) with NAT connectivity, and disable source/destination checks.

Configure a NAT EC2 instance to route private subnet internet traffic, enabling ip_forward, applying iptables rules, and updating route tables and security groups to direct traffic through the NAT instance.

Configure a NAT gateway to enable private instance internet access via a public subnet, an Elastic IP, and proper routing in AWS VPC.

Configure the private subnet to route internet traffic via a NAT gateway by updating the route table, then explore the VPC wizard for quick public or public-private subnet deployments.

Learn how VPC peering enables private IP communication between two VPCs in the same region, with non-transitive connections, CIDR overlap checks, routing and security updates, and without gateways or VPNs.

Create two VPCs with non-overlapping CIDR blocks, establish a VPC peering connection, accept the request, and configure routing tables to route traffic via the peering connection.

Implement and clean up AWS VPC peering between two VPCs by configuring routes, security groups, and network ACLs, then remove the connection and verify routes revert to local.

Learn to implement AWS VPC to VPC connectivity with OpenSwan by deploying two EC2 instances in public subnets and configuring private subnets, security groups, and IPsec VPN routing.

Create two non-overlapping VPCs, attach internet gateways, and configure public and private subnets with routes to enable internet access for a demo vpn setup.

Launch two amazon linux t2.micro ec2 instances in two vpcs, assign elastic ips, and configure security groups and routing to enable a vpn tunnel.

Configure OpenSwan on two instances to establish a VPN between VPCs by updating route tables with CIDR blocks and deploying IPsec configuration files.

Configure openswan vpn on two instances by applying a base template, inserting elastic ip s and vpc ids, and preserving formatting while setting a demo passkey.

Configure an OpenSwan ipsec tunnel between two instances by starting services, enabling autostart, disabling icmp redirects, restarting network, and verifying with ip set verify and ping.

Learn to use OpenVPN for SSL-based VPC connectivity between two AWS VPCs across regions, enabling disaster recovery and high availability via an AMI from the Amazon Marketplace.

Deploy VPC in Singapore and North Virginia by creating two VPCs with non overlapping CIDR blocks 10.0.0.0/16 and 192.168.0.0/20, then connect them using OpenVPN.

Attach internet gateways to two VPCs, configure routing tables for internet access, and deploy an OpenVPN instance with an elastic IP to enable a site-to-site VPN via a customer gateway.

Establish an OpenVPN tunnel by creating and attaching a virtual private gateway to a vpc, updating route tables with 10.0.0.0/16, and propagating them to connect Singapore and North Virginia.

Deploy an AWS VPC using the AWS CLI and CloudFormation templates, verify configurations in the AWS management console, and learn to create subnets, internet gateways, and other networking resources.

Visualize and deploy AWS VPCs with CloudFormation templates, defining VPCs, subnets, internet gateways, and route tables. Use the designer to manage dependencies, validate, and deploy stacks that rollback on errors.

Explore cloud computing basics within AWS, highlighting on-demand resources, virtualization, scalability, and benefits that drive public, private, and hybrid cloud deployments for modern applications.

Explore the three cloud service models—IaaS, PaaS, and SaaS—and how AWS delivers on-demand, scalable resources with secure, cost-efficient op-ex pay-as-you-go.

Explore how startups and enterprises use AWS for development, data analytics, mobile apps, and hybrid cloud, boosting speed to market while reducing infrastructure and operational costs.
