Cloud computing is sold as magic. Operationally it is rented infrastructure with APIs: servers, storage, databases, identity, and networks. You gain speed of provisioning. You do not gain a free pass on backups, IAM, or application design.
What you rent vs what you still own
| Usually the provider | Still you |
|---|---|
| Hardware failure in the data centre | Who can delete the production database |
| Physical security of the facility | Application bugs and leaked keys |
| Optional managed database patches | Whether you actually turned backups on |
| Global network | Data residency and encryption choices |
Choosing a vendor is next: AWS vs Azure vs Google Cloud. Moving existing systems is where teams get hurt — ten migration mistakes.
FAQ
Is cloud always cheaper than a server in the office?
Not always. It is often cheaper when you need elasticity, geographic reach, or you cannot staff a data centre. It is more expensive when you lift a always-on server and never right-size it.
If you need software built around a real workflow — not a stack of disconnected tools — see Devzin application development or start a conversation.
