Authentication, authorization and lifecycle.
Authentication proves who you are; authorization decides what you may do; identity management maintains both over time.
- 05IT Infrastructure
Compute, storage, virtualization and hosting.
The compute, storage, network and platform foundation on which applications and data depend.
- 06Cloud Computing
Service models and the shift to an API driven control plane.
On demand delivery of compute, storage, networking and platform services over a network, billed by consumption and managed through APIs.
- 07IT Operations
How an environment is kept healthy day to day.
The disciplines that keep a technology estate available, secure, documented and improving, day after day, not project by project.
