multi-cloud-architecture

multi-cloud-architecture is a skill for Claude Code, Codex from NOMARJ/sigil. It costs 50 tokens per session (1,175 once invoked), scanned A, a copy of multi-cloud-architecture, Apache-2.0.

A decision guide for designing systems across AWS, Azure, and GCP instead of relying on one cloud provider. It compares equivalent compute, storage, database, and other services.

In plain words
What is it for?
Use it to plan multi-cloud systems, select equivalent services, prepare migrations, design cloud-agnostic applications, or compare costs and capabilities across providers.
Why use it?
It helps you choose services deliberately when avoiding vendor lock-in, moving between providers, or combining their strengths. It also provides a way to compare options across clouds.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

multi-cloud-architecture scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to multi-cloud-architecture — 42 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Multi-Cloud Architecture

Decision framework and patterns for architecting applications across AWS, Azure, and GCP.

Purpose

Design cloud-agnostic architectures and make informed decisions about service selection across cloud providers.

When to Use

  • Design multi-cloud strategies
  • Migrate between cloud providers
  • Select cloud services for specific workloads
  • Implement cloud-agnostic architectures
  • Optimize costs across providers

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
