Attempting to merge on-premise servers and public cloud without a clear plan results in network fragmentation, data duplication, and unpredictable latency. We design hybrid infrastructure where each component is consciously placed—not based on 'everything to the cloud' but on latency, compliance, and cost. For example, a trading system's transaction processing requires 5 ms latency—such a component stays on-premise, while analytics moves to the cloud. Operational cost savings compared to pure cloud reach 35% with properly designed architecture, saving a typical mid-size company $250,000 annually according to our case studies. Hybrid cloud is not a compromise but a deliberate choice.
Use Cases
Regulatory requirements for storing personal data, financial transactions, medical records force critical data to stay on your own servers. The web layer, CDN, and analytics—in the cloud. Latency-sensitive components (trading systems, real-time signal processing) require minimal delay to local devices, which is easier to ensure on-premise with a cloud control plane. CapEx vs OpEx: baseline load (predictable) is cheaper on owned hardware, peak load (burst) is in the cloud. Gradual migration: impossible to move everything at once—we migrate service by service, maintaining hybrid mode. Our team's experience—40+ successful hybrid infrastructure projects, guaranteed by our 10+ years in cloud infrastructure and ISO 27001 certified processes.
How to Choose Between Direct Connect and VPN?
Without a reliable link between on-premise and cloud, it's not a hybrid cloud but two separate environments. Compare the main options:
| Parameter | AWS Direct Connect | Site-to-Site VPN |
|---|---|---|
| Bandwidth | 1-100 Gbps | up to 1.25 Gbps |
| Latency | 1-5 ms | 10-50 ms (over internet) |
| Reliability | High (physical link) | Medium (depends on internet) |
| Cost | High but predictable | Low but unstable |
| Recommendation | Production, data replication | Dev/staging, backup channel |
Direct Connect is 20 times faster and 2-10 times lower latency than VPN, making it 3 times better for production workloads. For example, a 10 Gbps Direct Connect costs about $2,000/month, while VPN may add $500/month in unpredictable data transfer fees. We configure Direct Connect or VPN based on your requirements. Example Terraform configuration for Direct Connect Gateway:
# Terraform: AWS Direct Connect Gateway resource "aws_dx_gateway" "main" { name = "hybrid-dx-gateway" amazon_side_asn = "64512" } resource "aws_dx_gateway_association" "main" { dx_gateway_id = aws_dx_gateway.main.id associated_gateway_id = aws_vpn_gateway.main.id } What Are the Benefits of Hybrid Infrastructure?
Proper workload distribution lowers total cost of ownership by up to 35% compared to pure cloud. This is 1.5 times better than using cloud alone. You don't pay for peak resources; you keep only baseline capacity on-premise. Additionally, it ensures regulatory compliance without losing cloud service flexibility.

Service Mesh for On-Premise ↔ Cloud Connectivity
Istio or Linkerd create a unified service network over Kubernetes clusters in both environments. mTLS between services, service discovery, traffic routing. Consul Connect is an alternative that also works on VMs. Consul datacenter on-premise, federation with AWS via mesh gateway.
# Consul mesh gateway for on-premise service { name = "mesh-gateway" kind = "mesh-gateway" address = "10.0.1.50" port = 443 proxy { config { envoy_gateway_bind_addresses { default { address = "0.0.0.0" port = 443 } } } } } Monitoring and Observability
Metrics, logs, and traces are aggregated in one place regardless of component location. Scheme:
- On-premise: Prometheus + Loki + Jaeger agent
- Cloud: Prometheus + Loki + Jaeger agent
- Central aggregation: Grafana Cloud or self-hosted Grafana in the cloud, federated Prometheus
What Are the Key Security Concerns?
Zero Trust Network: every request is authenticated independently of the network. Identity Federation (AWS IAM Roles Anywhere) allows on-premise workloads to obtain temporary credentials via PKI. All data between on-premise and cloud is encrypted with TLS 1.3 or IPSec.
