What are the five essential characteristics of cloud computing according to NIST?
Options
- On-demand self-service, network access, pooling, elasticity, measured service (Correct option)
- Cheap, fast, small, secure and free, in that order of priority
- Compile, test, build, deploy and monitor, in that exact order
- Frontend, backend, database, cache and queue, as five layers
Answer
On-demand self-service, broad network access, resource pooling, rapid elasticity, measured service
Why
NIST (SP 800-145) defines cloud computing with five essential characteristics:
- On-demand self-service: you provision resources yourself without human contact.
- Broad network access: available over the network from many devices.
- Resource pooling: the provider's resources are shared among many customers.
- Rapid elasticity: resources grow and shrink quickly with demand.
- Measured service: usage is metered, so you pay for what you use.
Remember
Self-service, network, pooling, elasticity, measured.
