VPC design involves planning your network topology across availability zones, configuring subnets for different tiers, and establishing routing rules. This Skill covers subnet segmentation, inter-AZ communication, and traffic routing strategies to isolate workloads and optimize connectivity in cloud environments.

Load balancer configuration requires setting up health checks to monitor backend instance availability, defining routing strategies across targets, and integrating DNS records for traffic distribution. This Skill provides patterns for ALB setup, health check tuning, and DNS management to ensure reliable traffic flow.

Network troubleshooting maps problems across OSI layers, traces routing paths, validates security group and firewall rules, and checks DNS resolution. This Skill provides diagnostic workflows and common checks to isolate connectivity failures in cloud and on-premises environments.

Network security hardening involves configuring TLS encryption for data in transit, defining firewall rules to restrict traffic flows, and implementing least-privilege access. This Skill covers certificate setup, rule design patterns, and security best practices to protect your infrastructure.

Yes. The topology design, load balancing, DNS, and security patterns apply to both cloud and on-premises environments. This Skill addresses common architectural decisions regardless of deployment model, so your infrastructure can follow consistent design principles.

Performance tuning addresses latency and throughput by optimizing routing paths, selecting appropriate health check intervals, and configuring load balancing strategies. This Skill covers OSI layer considerations and configuration trade-offs to meet your application's performance requirements.
