Cloud Computing Reference Library

This page is a verified index of primary sources for cloud & devops: official documentation, developer and API portals, source repositories, SDKs, downloadable or offline documentation, a two-track learning path, and free-access research literature.

It is a navigation layer, not a tutorial. Where the rest of this book explains a concept, this page tells you which document to open to get the authoritative answer, and in what order to read things. Every link was HTTP-verified on the date shown below; sources that block automated checkers but work in a browser are flagged rather than silently dropped.

Hyperscale and developer-focused providers, infrastructure as code, containers and orchestration, observability, reliability frameworks, and a two-track path from the OCI specs to Kubernetes internals and platform engineering.

93 entries across 10 categories, plus 57 education & reference-implementation resources (26 basic / 31 advanced), plus 10 video resources and 5 conference sources.

Every link HTTP-verified on 2026-10-07.

Papers We Love — distributed systems

Education & reference implementations

Two tracks: Basic builds the foundations, Advanced is about reading and extending real implementations. Everything listed is free and publicly accessible.

Basic

26 resources across 6 topics.

Understand the primitives before the platforms

Kubernetes, learned properly

  • Kubernetes the Hard Way — Build a cluster by hand, component by component, with no automation. The single most effective Kubernetes learning resource.
  • Kubernetes documentation — Work through the concepts section in order; it is well structured.
  • Kubernetes reference — The API reference is authoritative. Learn to read it rather than copying YAML.
  • Helm — Packaging and templating, once raw manifests become painful.

Pick one cloud and go deep

Free structured training from the providers

Infrastructure as code, from the start

  • Terraform documentation — Learn state, modules and providers. State is where every beginner gets hurt.
  • Terraform Registry — The real reference for every resource you will write.
  • OpenTofu — The open-source fork; worth knowing which you are running.
  • Pulumi — If your team would rather write code than HCL.

Finding and reading papers

  • Papers We Love — Start here when you do not yet know which papers matter. Curated by subfield, with recorded talks.
  • The Morning Paper archive — Around a thousand papers summarised in plain language. No longer updated; still one of the best free CS resources.
  • Semantic Scholar — Free citation graph. The ‘highly influential citations’ filter is the fastest way to find what a paper actually changed.
  • Unpaywall — Install the extension. Most paywalls stop appearing, legally, because the author deposited a copy.
  • ar5iv — Read any arXiv paper as HTML instead of a two-column PDF. Swap arxiv.org/abs for ar5iv.labs.arxiv.org/html.

Advanced

31 resources across 6 topics.

Reliability engineering

Observability in depth

  • OpenTelemetry specification — Read the spec, not just the SDK quickstart. The semantic conventions matter more than the API.
  • OpenTelemetry docs — Collector architecture and instrumentation strategy.
  • OpenTelemetry source — SDKs and the Collector; the Collector is a good study in pipeline design.
  • Prometheus — PromQL, recording rules, and the pull model’s consequences.
  • Thanos design docs — How to make Prometheus global and durable; a real distributed-systems design.
  • Grafana Loki — Label-indexed logging — understand the trade-off before adopting it.
  • Jaeger — Trace storage and sampling strategies.

Platform engineering & GitOps

  • Argo CD — GitOps in practice: sync waves, drift detection, app-of-apps.
  • Flux — The other graduated GitOps toolkit; more composable, less opinionated.
  • Crossplane — Infrastructure as Kubernetes resources. Read the composition model carefully.
  • Backstage — Developer portals and software catalogues.
  • CloudEvents — A small spec that removes a lot of integration friction.

Kubernetes internals

  • Kubernetes source — Read the controller pattern first — controller-runtime and one simple controller.
  • Kubernetes reference docs — API machinery, admission control, the resource model.
  • etcd — The Raft store underneath. See the distributed-systems index for the consensus material.
  • Knative — Serverless primitives built as Kubernetes extensions — a good study in extending the API.
  • Nomad — A simpler scheduler. Useful for seeing which Kubernetes complexity is essential and which is incidental.

Serverless & edge

  • Cloudflare Workers — The best documentation of the edge compute model, including Durable Objects and R2.
  • Fly.io docs — Machines API and multi-region deployment, explained unusually honestly.
  • Knative Serving — Scale-to-zero and request-driven autoscaling.
  • OpenFaaS — Functions without vendor lock-in.
  • AWS CDK — Typed infrastructure for serverless architectures.

Video courses, channels & talks

10 resources across 1 group. Every channel and playlist below was fetched and title-verified on 2026-10-09. Handles drift and several plausible-looking handles resolve to the wrong channel, so a 200 response is not proof of identity — the links here were each checked against the channel title.

Channels & conference recordings

  • AWS — Official AWS: re:Invent sessions and service deep dives — a huge, searchable archive.
  • Google Cloud Tech — Official Google Cloud: product talks and architecture series.
  • Microsoft Azure — Official Microsoft Azure channel: Ignite sessions and service explainers.
  • CNCF — KubeCon keynotes and project-maintainer talks across the cloud-native landscape.
  • Kubernetes — Official Kubernetes community channel.
  • The Linux Foundation — The Linux Foundation channel: kernel and LF event recordings.
  • InfoQ — Conference keynotes and architecture talks — good for orientation, verify specifics elsewhere.
  • HashiCorp — HashiConf talks: Terraform, Vault, Consul, Nomad — vendor, but the design talks are real.
  • Grafana Labs — GrafanaCon and observability talks; the open-source telemetry stack is documented here in video form.
  • Tech Field Day — Multi-vendor engineering sessions on cloud and infrastructure; good for comparing implementations.

Note: Cloud video is dominated by vendor marketing; it is worth watching for service mechanics and release behaviour, and worthless for architecture judgment.

Conference videos, notes & archives

5 resources across 2 groups. Conference recordings are the primary-source tier of video: the speaker is usually an author of the paper, and where a talk exists the proceedings entry is often open at the same link. Every URL here returned 200 on 2026-10-09 unless the note says otherwise.

Cloud video is mostly vendor content, with two exceptions: SREcon is practitioner-authored, and the open-source conferences publish everything.

Conference channels & video archives

  • SREcon — The site reliability engineering conference, run by USENIX — practitioner-authored, no marketing.
  • USENIX ATC ’26 — Where the research behind cloud behaviour gets published; open.
  • EuroSys — Proceedings and selected recordings for the systems side of cloud.
  • FOSDEM video archive — Containers, cloud-infrastructure and observability devrooms.

Notes, proceedings & paper-adjacent archives

  • USENIX ;login: — Operations and reliability write-ups; the text equivalent of SREcon.

If you only do three things

  1. Do Kubernetes the Hard Way. Build a cluster component by component with no automation. Nothing else teaches it as well.
  2. Read the OCI image and distribution specs. Two short documents that demystify the entire container ecosystem.
  3. Read the Google SRE book’s SLO and error-budget chapters. Free, and they change how you argue about reliability.

Honest notes

  • Pick one cloud and learn it deeply before comparing. IAM and networking are the hard parts everywhere; the rest is services.
  • Terraform’s licence changed in 2023 (BUSL), which is why OpenTofu exists. Know which one your organisation is actually running.
  • Linode is now Akamai Cloud Computing. Old documentation links redirect; bookmarks will rot.
  • The CNCF Landscape is not a shortlist. Filter to graduated projects, or it is actively unhelpful.
  • Instrument with OpenTelemetry, not a vendor SDK. It is the one decision here that is genuinely hard to reverse.
  • The free tiers of AWS Skill Builder, Google Cloud Skills Boost and Microsoft Learn are substantial. Most people pay for courses that duplicate them.
