What it means
Broad network access, on-demand self-service, resource pooling, rapid elasticity, and measured service work together to create a programmable and consumption-oriented environment.
Why it matters
These characteristics affect architecture, contracts, security boundaries, capacity planning, cost controls, and the evidence an organization needs to manage the service.
Practical focus
- Confirm that services can be provisioned and governed through repeatable interfaces
- Measure usage and allocate cost to accountable owners
- Plan for pooled infrastructure and changing physical placement
- Use elasticity intentionally rather than as an excuse for unlimited growth
Common mistakes
- Calling any hosted system cloud
- Ignoring metering and ownership
- Assuming elasticity automatically produces resilience
