# Hybrid cloud

> Hybrid cloud is an IT architecture that connects private infrastructure (on-premises servers or a private cloud) with public cloud services into one coherently managed environment, letting workloads run wherever they fit best.

**Hybrid cloud** is an infrastructure model that combines a private environment — on-premises servers, colocation or a private cloud — with public cloud resources, connected and managed as a single system. The point is to place each workload where it fits best: steady, sensitive or latency-critical systems stay on infrastructure you control, while elastic and experimental workloads use the public cloud's pay-as-you-go capacity.

## How hybrid cloud works

Three ingredients make separate environments behave like one platform:

- **Secure connectivity** — a site-to-site [VPN](https://nodea.io/en/glossary/vpn) or a dedicated private link (AWS Direct Connect, Azure ExpressRoute) joining the networks;
- **A common workload format** — [virtualization](https://nodea.io/en/glossary/virtualization) and containers make applications portable, whether as VM images or a Kubernetes cluster spanning both sides;
- **Unified operations** — one deployment pipeline, one monitoring stack, one identity provider and consistent security policies everywhere, typically enforced through infrastructure-as-code.

A classic traffic pattern is cloud bursting: the private environment handles baseline load, and when demand spikes past its capacity, additional instances spin up in the public cloud and are torn down when the peak passes.

## Practical use cases

Hybrid architectures dominate wherever regulation meets ambition: banks, healthcare providers and public institutions that must keep certain data on premises or in-country, yet still want cloud analytics, AI services or developer velocity. Other common scenarios include disaster recovery — replicating the primary environment to the cloud instead of maintaining a second data centre; gradual migration of legacy systems; seasonal e-commerce scaling; and cost engineering, where predictable 24/7 workloads run on owned or leased dedicated servers (often several times cheaper per unit of compute) while variable workloads rent cloud capacity by the hour.

The trade-off is operational complexity: network and identity integration, keeping security consistent across two worlds, and data egress fees between environments. A hybrid design pays off when the placement of workloads is a deliberate architectural decision — not when it merely papers over an unfinished migration.

### What is the difference between hybrid cloud and multi-cloud?

Hybrid cloud integrates a private environment with a public cloud into one system. Multi-cloud means using several public cloud providers side by side — with or without integration, and with or without any private component. Many enterprises end up running both patterns at once.
