Solution 01 — IaC Governance

Multi-Account IaC Governance Pack

Available

One hub, dozens of accounts. Every infrastructure change flows through code and PR approval — no more manual deploys.

Problems this solves

  • Manual deploys no longer scale with account count
  • Cannot answer who changed what, when
  • Only seniors can touch production safely

What's included

  • Hub design + cross-account roles rolled out to all accounts
  • Two-repo split: juniors touch parameters only
  • PR-gated CI/CD with auto-lint and diff-based deploy
  • Naming, tagging, and account registry (SSOT)
  • Runbooks for both senior and junior roles
Generalized from a ~40-account retail group deployment Proven twice, incl. a PCI DSS estate
150万円〜 Est., tax excl. Varies by account count / 1–2 months
ハブアカウント テンプレート シニア担当 パラメータ 若手担当 自動検証(構文・参照チェック) push のたびに実行 プルリクエスト承認ゲート シニア承認なしに本番へ届かない 差分検知デプロイ 変わった分だけ自動配布 AssumeRole 本番アカウント 検証アカウント ログ集約 セキュリティ … 数十アカウントへ横展開 導入後にできること 全変更がコードとして履歴に残る 監査対応が「リポジトリを見せる」で済む 若手が安全に本番作業へ参加できる アカウント追加が台帳1行+数分
Simplified architecture
Provenance: generalized from a governance platform we designed and still operate across ~40 AWS accounts (including a PCI DSS estate) at a major retail group — with all client-specific information removed.
Solution 02 — Transparent Operations

Managed AWS Operations with Transparency Portal

Early Access

The real complaint about outsourced ops is opacity. Our managed service ships with a customer portal — monitoring status, work history, and change approvals, visible to you.

What's included

  • Full managed ops: monitoring, alerting, first response
  • Customer portal: monitoring, work log, change approvals
  • Cross-account visibility over your AWS estate
  • Monthly reports and improvement proposals
Built on our zero-major-incident practice Private network, SSO (Keycloak)
月額 30万円〜 Est., tax excl. Portal rolling out to early customers
お客様のAWS 本番アカウント 検証アカウント …複数アカウント 読み取り専用ロールのみ付与 (書き込みは承認フロー経由) EMW運用基盤 (閉域・マルチテナント) 収集・監視エンジン テナント分離を強制 お客様 ポータル SSOログイン 閲覧はいつでも

Solution 03 — Private File Exchange

Private File Exchange Build Pack

By Consultation

For organizations that can't push file exchange to external SaaS: a file-sharing platform that lives entirely inside your own AWS.

Capabilities

  • S3-backed storage with expiring guest links
  • SSO / MFA integration (e.g., Keycloak)
  • Full audit trail of every transfer
  • Outlook add-in / mobile, as required
Data never leaves your AWS No per-seat fees
個別見積もり Scoped per requirements — free initial consultation

Good fit if

  • Regulations or contracts block external file SaaS
  • Trying to retire password-zip emails
  • Per-seat SaaS pricing doesn't scale for you

All solutions are anonymized generalizations of architectures we've built and operated in production. No client-specific code or data is included.
