What problem does it solve? Connecting on-premises data centers to cloud platforms requires choosing between VPN and dedicated circuits, configuring BGP routing, and ensuring redundancy across AWS, Azure, GCP, and OCI, which is error-prone without structured guidance. ## Core Features & Use Cases - Multi-Cloud Connectivity Options: Terraform examples and guidance for AWS Site-to-Site VPN and Direct Connect, Azure VPN Gateway and ExpressRoute, GCP Cloud VPN and Interconnect, and OCI IPSec VPN and FastConnect. - Hybrid Network Patterns: Reference architectures for hub-and-spoke, multi-region, and multi-cloud hybrid topologies with BGP routing configuration. - HA, Security, and Cost Guidance: Dual-tunnel failover, active-active ECMP routing, encryption best practices, monitoring commands, and cost optimization strategies. - Use Case: An enterprise migrating workloads gradually to AWS and Azure uses this Skill to provision redundant VPN tunnels with BGP failover, then upgrades to Direct Connect and ExpressRoute for production traffic. ## Quick Start Help me set up a redundant site-to-site VPN connection between my on-premises data center and AWS with BGP routing.
