Hybrid cloud combines your own infrastructure with cloud services. For many companies it is the pragmatic path because not everything has to move to the cloud.
Parts of the systems run in your own data centre or server room, others with cloud providers, connected through secure network links and shared identities. Where which workload lives is decided by data protection, performance, cost and flexibility requirements.
Typical reasons
Data that must or should stay local.
Legacy applications that cannot easily be moved.
Load peaks you flexibly shift to the cloud.
Gradual migration instead of one big move.
Avoiding too much dependence on one provider.
What matters
Identity: uniform sign-in for on-premises and cloud.
Network: secure, performant connection.
Security and backup: the same standards in both worlds.
Cost: weigh ongoing cloud costs against investment and operation.
Operation: clear responsibilities so nothing falls between the worlds.
Limits
Hybrid means more complexity than "on-premises only" or "cloud only". Without a clear architecture, duplicate administration and security gaps arise. Planning up front pays off.

Frequently asked questions
What is hybrid cloud?
The combination of your own infrastructure and cloud services, connected through network and shared identities.
Who is hybrid cloud suited for?
Companies with legacy applications, data protection requirements or the wish for gradual migration.
Is hybrid more expensive than pure cloud?
Not across the board. It depends on load, operation and requirements. An economic assessment in the individual case is sensible.
