Hybrid Cloud Architecture

Design hybrid topologies that put latency-sensitive workloads on dedicated hardware and burstable workloads on cloud — with secure networking between them.

Overview

Pure cloud is expensive for predictable heavy workloads. Pure dedicated is rigid for spiky traffic. Hybrid cloud — dedicated hardware for the steady baseline, cloud for bursts — gives you the economics of dedicated with the elasticity of cloud. But getting the architecture right is hard: networking, security, data sync, failover, and observability all need to span both worlds.

CB4UHost designs hybrid cloud architectures that actually work in production. We place workloads based on their characteristics — databases on dedicated, web tier on cloud, batch processing on spot — and design the networking, security, and failover to tie it all together.

We're vendor-neutral on both sides. Dedicated can be Hetzner, OVHcloud, Equinix colocation, or your own datacenter. Cloud can be AWS, GCP, Azure, or a regional provider. The right combination depends on your workload, region, and budget.

Every engagement ends with reference architectures, network diagrams, an IaC codebase, and a 60-minute walkthrough so your team can operate the hybrid stack.

What's included

Workload placement strategy

Each workload is placed on dedicated, cloud, or hybrid based on its characteristics and economics.

Network architecture

Site-to-site VPN or dedicated interconnect, subnet design, routing, and firewall rules.

Security + identity

Federated identity, secret management, encryption in transit and at rest, compliance mapping.

Data sync + replication

Database replication, object storage sync, and cache invalidation across dedicated and cloud.

Failover + DR

Failover runbooks for dedicated-to-cloud and cloud-to-dedicated scenarios, with RTO/RPO targets.

IaC + runbooks

Terraform or Pulumi codebase for the entire hybrid stack, plus operational runbooks.

How we work

1

Workload analysis

We analyze each workload for placement — steady/bursty, latency-sensitive/burstable, predictable/spiky.

2

Architecture design

We design the hybrid topology — dedicated and cloud components, networking, security, data flow.

3

IaC build-out

We build the entire stack as code — Terraform/Pulumi for cloud, Ansible/Python for dedicated.

4

Failover testing

We test failover in both directions and document RTO/RPO.

5

Handover + runbooks

We hand over the IaC, runbooks, and a 60-minute walkthrough.

FAQ

When does hybrid make sense?

When you have a predictable baseline (good for dedicated) plus spiky traffic (good for cloud), or when compliance requires some data on hardware you control. Pure cloud is simpler; hybrid is cheaper at scale but operationally more complex.

How do you handle networking between dedicated and cloud?

Three options: site-to-site VPN (cheapest, ~100Mbps), dedicated interconnect like AWS Direct Connect or Equinix Fabric (1-10Gbps, pricier), or SD-WAN overlay. We recommend based on your bandwidth and latency needs.

Can you do multi-cloud hybrid (e.g. dedicated + AWS + GCP)?

Yes, but we usually advise against it unless you have a specific reason (e.g. region coverage, compliance). Multi-cloud adds operational overhead — Kubernetes helps, but it's still more to manage. We'll show you the cost/benefit.

How do you handle failover between dedicated and cloud?

We design failover in both directions: dedicated-to-cloud (if dedicated fails) and cloud-to-dedicated (if cloud has an outage). We test both scenarios and document RTO/RPO. Database replication is the hard part — we use read replicas or log shipping depending on the database.
