For a hybrid cloud to work, integration between several different types of infrastructure is key.

A hybrid cloud is a combination of two or more different types of infrastructure: a public cloud, and either a private cloud or on-premise infrastructure. Hybrid cloud deployments are increasingly common; many companies want to combine the power of public cloud computing with more tightly controlled private infrastructure.
Hybrid cloud architecture can vary quite a bit. A hybrid cloud deployment could combine on-premise infrastructure with a public cloud:
It could also combine a public cloud with a private cloud:
Or it could combine multiple public clouds, private clouds, and on-premise infrastructure. Regardless of the specific setup used, all hybrid cloud architecture will have some traits in common:
*An API, or application programming interface, allows an application to "call" a feature or functionality from another application – or in this case, a cloud service – and incorporate that feature or functionality into the application's own service.
**An "SLA" is a service-level agreement, and it defines the services that a cloud vendor will provide.
For hybrid clouds, the network connections between the different infrastructures are very important. If they are not connected, an organization isn't truly running a hybrid cloud. Instead, they are running several clouds in parallel with each other, and data may not be aligned across all clouds.
Public clouds, private clouds, and on-premise infrastructure can be connected via these methods:
Cloudflare makes it easier to manage hybrid cloud deployments in addition to other types of cloud deployments such as multi-cloud. The Cloudflare cloud network, which is distributed across 310 cities in 120 countries, sits in front of any cloud infrastructure and handles DNS, DDoS protection, content acceleration, TLS encryption, and other essential functions. Cloudflare also helps with user access control, a crucial aspect of any cloud deployment.
