Cloud Computing Essentials - 2026 Version

Learn the AWS VPC concept using a mansion analogy. Select a CIDR block, create subnets as rooms, and apply security groups and NACLs to control traffic.

Explore how a virtual private cloud uses public and private subnets, with network access control lists as doors and security groups as resource locks to control traffic and access.

Plan and assign AWS VPC CIDR blocks to manage capacity and subnet organization using private ranges. Avoid overlaps and oversized blocks to enable scalable internet access and secure networks.

Explore how IP addressing and CIDR blocks drive scalable, secure cloud networks in AWS VPC, guided by RFC 1918 and the private IP ranges it defines.

Provision a VPC in AWS using the Management Console, configure CIDR blocks, subnets, and naming conventions across two availability zones.

Test the VPC by provisioning an EC2 web server in a VPC, using a Linux 2023 AMI on a t2.micro, with a web server key pair, subnets, and security groups.

Explore how a running EC2 instance in a VPC uses a /16 CIDR block to assign private and public IPs within a subnet and how security groups allow port 22.

Map the traffic path from internet to an EC2 instance via subnets and NaCl, then security group rules, ports 22, 80, 443, and 0.0.0.0/0 access.

Learn how network security groups control inbound and outbound rules to expose a Linux web server on port 80, while safely documenting changes for scalable cloud environments.

Explore how network ACLs control subnet traffic in AWS with ordered inbound rules and numbers; learn why lower numbers win and how this differs from security groups.

Explore NACL configuration basics, including type, protocol and port range for common traffic like HTTP and HTTPS, and how source and action control inbound and outbound rules in stateless NACLs.

Compare stateless and stateful firewalls using a party host analogy, showing stateless checks packets against rules while stateful tracks connection state and allows return traffic via security groups and ACLs.

Explore how route tables direct VPC traffic and control internet access using CIDR block destinations and targets like internet gateways, VPC peering, and NAT gateways.

Understand how the internet gateway links a VPC to the internet, enabling internet-bound traffic via the VPC's route table, so subnets reach external resources.

Explore VPC peering, a private AWS connectivity between two VPCs that uses private IP addresses over the AWS backbone, enabling 1-to-1, non-transitive networking and hub-and-spoke architectures with on-premises links.

Launch two ec2 instances in the default vpc and workloads vpc, enable public ip assignment, and test vpc peering connectivity by pinging the other’s private ip.

Open inbound icmp rules on both ec2 security groups to allow traffic from each vpc cidr block and configure routes via the vpc peering to enable bidirectional ping.

Leverage VPC peering troubleshooting with Amazon Q to trace traffic between EC2 instances using Reachability Analyzer, highlighting ENIs, security groups, NACLs, and route tables for quick problem diagnosis.

Explore Google Cloud Platform's public cloud services, featuring compute, storage, networking, AI and ML, and security and operations. Leverage global infrastructure, on-demand resources, and scalable solutions for diverse applications.

Explore Google Cloud compute offerings from Compute Engine virtual machines to container services like GKE and Anthos, plus serverless options App Engine, Cloud Run, Cloud Functions, and migration capabilities.

Explore Google Cloud Storage for structured and unstructured data, with standard, nearline, coldline, and archive classes, bucket storage, and NoSQL options such as Firestore.

Explore Google Cloud networking, including vpc with subnets and firewalls, cloud vpn, interconnect, and direct peering, and use load balancers, cloud armor, cloud dns, and cloud cdn for scalable traffic.

Explore Google Cloud's AI and ML services, featuring Vertex AI, AI platform notebooks, and deep learning virtual machines. Leverage vision, speech, natural language, translation, and Dialogflow for AI solutions.

Explore Google Cloud security services like Cloud Armor, VPC Service Controls, DLP, and encryption with KMS and Cloud HSM to protect perimeters, prevent data exfiltration, and safeguard sensitive data.

Master proactive threat detection and incident response with Google Chronicle and Security Health Analytics. Use Security Command Center, cloud logging, monitoring, and trace to investigate, contain, and improve security posture.

Explore the virtual private cloud (VPC) in Google Cloud, including subnets, routes, and firewall rules, and learn how IP addressing enables intercommunication across VMs, GKE, VPN gateways, and databases.

Learn how a virtual machine hosts a public web frontend and a private backend inside a cloud VPC, with security controls, public-private separation, and subnet CIDR concepts.

Explore the concept of a virtual private cloud (VPC) and its isolation of public and private networks. Learn how CIDR blocks and subnets define IP addressing in Google Cloud.

Explore VPC key features, including ipv4 and ipv6 support, private ip communication, firewall rules, custom routes, and regional subnets, plus hybrid connectivity via cloud vpn or interconnect.

Explore Google Cloud VPC features and capabilities, including private networks for compute resources, internal load balancing, hybrid connectivity, and flow logs.

Learn to create and configure a Google Cloud VPC, including default networks, regional subnets, MTU settings, private Google access, flow logs, hybrid subnets, and firewall rules for cloud networking.

Deploy a Windows compute instance in a asia east 1 vpc, then configure firewall rules to allow RDP on port 3389 from the internet, using public and private IPs.

Define and test GCP firewall rules to govern ingress and egress in a VPC, targeting instances by tags or service accounts, with optional logging and priority-based evaluation.
