The first two chapters address decision makers: operating models, accountability, and the dependency chain behind a dependable service. Chapters 3 to 5 build the technical foundation step by step, from a single OpenStack IaaS request to a Kubernetes platform with separate environments for different applications. Each technical chapter has a public lab with complete walkthroughs. Agent skills let an AI coding agent apply the chapters to a concrete case or an existing OpenStack project. ## What this series covers
🧭 1. Cloud computing for public services: choosing an operating modelWhere and how a public service should run: describe the workload, separate placement, service layer and operating model, and keep accountability and an exit route with the public authority.Chapter 1: Cloud computing for public services: choosing an operating model
🏛️ 2. How cloud environments support dependable public servicesThe dependency chain behind a dependable public service, from physical conditions and IaaS through containers and platforms to shared capabilities and recovery.Chapter 2: How cloud environments support dependable public services
🖥️ 3. OpenStack and the IaaS technical baselineOne reviewable IaaS request on OpenStack: project, quota, compute, network and storage through Horizon, the command line and OpenTofu, then acceptance and cleanup.Chapter 3: OpenStack and the IaaS technical baseline

--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://experience-digital-transform.gitbook.io/experience-digital-transformation/cloud-for-dpi/gitbook.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
