Cloud computing provides access to infrastructure and managed capabilities without requiring an organization to build and operate every platform layer itself. Serverless removes hardware and operating-system management, while other parts of a system can still use lower layers. section 13.4.3
The practical choice is evolutionary rather than binary: combine curated cloud offerings with capabilities built or managed in-house, selecting each layer according to developer experience, security, and team cognitive load. section 13.4.3
Use cloud computing deliberately by asking:
- Which layers can a cloud provider manage more effectively than the organization? section 13.4.3
- Which existing services should be curated together instead of rebuilt internally? section 13.4.3
- Will the selected services reduce cognitive load and improve developer experience rather than merely lower apparent costs? section 13.4.3
A serverless platform
An organization adopts a serverless-based platform so the cloud provider manages hardware and operating systems. Security benefits from a smaller attack surface, while selected workloads may still access lower platform layers. section 13.4.3
Use the platform-layer diagram to compare shared capabilities, delegated services, and the boundaries between products and platform responsibilities. section 6.1.4
