# Hybrid Cloud Networking Configure secure, high-performance connectivity between on-premises and cloud environments using VPN, Direct Connect, and ExpressRoute. ## Purpose Establish secure, reliable network connectivity between on-premises data centers and cloud providers (AWS, Azure, GCP). ## When to Use - Connect on-premises to cloud - Extend datacenter to cloud - Implement hybrid active-active setups - Meet compliance requirements - Migrate to cloud gradually ## Connection Options ### AWS Connectivity #### 1. Site-to-Site VPN - IPSec VPN over internet - Up to 1.25 Gbps per tunnel - Cost-effective for moderate bandwidth - Higher latency, internet-dependent ```hcl resource "aws_vpn_gateway" "main" { vpc_id = aws_vpc.main.id tags = { Name = "main-vpn-gateway" } } resource "aws_customer_gateway" "main" { bgp_asn = 65000 ip_address = "203.0.113.1" type = "ipsec.1" } resource "aws_vpn_connection" "main" { vpn_gateway_id = aws_vpn_gateway.main.id customer_gateway_id = aws_customer_gateway.main.id type = "ipsec.1" static_routes_only = false } ``` #### 2. AWS Direct Connect - Dedicated network connection - 1 Gbps to 100 Gbps - Lower latency, consistent bandwidth - More expensive, setup time required **Reference:** See `references/direct-connect.md` ### Azure Connectivity #### 1.
