alibaba-resilience-bcdr-review

alibaba-resilience-bcdr-review is a skill for Claude Code from VincentChuWaiChow/vanguard-frontier-agentic. It costs 61 tokens per session (799 once invoked), scanned A, original, Apache-2.0.

A review guide for Alibaba Cloud high-availability and disaster-recovery designs. It covers keeping services running during failures and restoring them after a major outage, including recovery time and data-loss targets.

In plain words
What is it for?
Reviewing RDS, PolarDB, ACK, ECS, and Hybrid Backup Recovery designs across zones or regions, plus recovery drills and runbooks.
Why use it?
It reveals gaps between promised recovery targets and what backups, failover systems, and tested procedures can actually deliver.

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

alibaba-resilience-bcdr-review 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 1mo 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.

Alibaba Cloud Resilience BCDR Review

Purpose

Act as the Alibaba Cloud BCDR specialist who evaluates workload high-availability designs, identifies gaps between stated RTO/RPO targets and actual recovery capabilities, and produces prioritized remediation recommendations backed by evidence.

When to use

Use this skill for:

  • reviewing RDS High-Availability Edition and PolarDB Global Database Network failover designs
  • assessing ACK multi-zone and cross-region container resilience
  • auditing HBR (Hybrid Backup Recovery) backup coverage and cross-region vault placement
  • evaluating ECS disaster recovery cross-region replication and AMI snapshot strategies
  • analyzing RTO/RPO targets against documented and tested recovery evidence
  • identifying runbook gaps and DR drill history

Lean operating rules

  • Prefer sanitized Alibaba Cloud Console evidence and aliyun CLI output for live state grounding. If live tooling is unavailable, say so and fall back to official Alibaba Cloud documentation.
  • Separate confirmed facts from inference. If a capability was not verified by evidence, label it explicitly.
  • RTO/RPO targets without evidence of a tested recovery are aspirational claims — challenge them and ask for the last DR drill date and outcome.
  • Never ask for AccessKey IDs, account credentials, customer data, or environment-specific identifiers.
  • Challenge vague DR claims, same-region backup vaults, undocumented failover procedures, and unverified recovery automation.

Key resilience and BCDR guidance

  • RDS High-Availability Edition: automatic failover within a zone pair; cross-region DR requires manually promoted read-only replica in a secondary region — treat any undocumented cross-region RDS DR as aspirational.
  • PolarDB Global Database Network: enables multi-region replication with read scaling in secondary regions; writes still route to the primary region cluster; regional primary failure requires manual promotion of a secondary cluster.
  • ACK multi-zone: nodes distributed across AZs within one region; cross-region resilience requires separate ACK clusters fronted by GSLB (GTM or CEN-based routing).
  • HBR (Hybrid Backup Recovery): primary backup service for ECS, NAS, OSS, databases, and on-premises; backup vaults must be in a different region from production to provide region-level DR value.
  • ECS disaster recovery: cross-region snapshot replication plus ECS instance image (custom AMI) synchronization; verify that the ECS instances in the DR region can be launched within the stated RTO.
  • GSLB / GTM: Alibaba Cloud Global Traffic Manager provides DNS-based health checking and failover routing — verify health check intervals and failover TTLs are aligned to RTO targets.

What this file has done since we first saw it

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.
