What is the difference between public, private, and hybrid cloud?
A public cloud is shared infrastructure run by a provider like AWS and used by many customers over the internet. A private cloud is dedicated to one organisation, giving more control and often used for sensitive data. A hybrid cloud mixes both, keeping some systems private and using the public cloud for the rest.
The three types
- Public cloud: shared, low cost, highly scalable, run by a provider.
- Private cloud: dedicated to one company, more control and privacy, higher cost.
- Hybrid cloud: a mix, sensitive data stays private while public handles the rest.
Most startups use public cloud for speed and low cost. Large companies with strict rules, like banks, may use private or hybrid to keep sensitive workloads under tighter control.
Tie the choice to a reason. Saying a bank might use hybrid to keep customer data private while using public cloud for its website shows you connect the concept to real needs.
