    Part of the Managed Cloud Kubernetes Ledger (edition 2026-10-13). How the scores work: methodology.

    1. Snapshot

    • Tier: Asian hyperscaler
    • Owner: Alibaba Group Holding (listed in New York and Hong Kong), cloud unit Alibaba Cloud Intelligence
    • Licence model: ACK Pro hourly cluster fee (example USD 0.09 per hour), Basic free for testing only; nodes and serverless pods billed as ECS / ACS resources
    • Products scored: ACK managed Pro with Auto Mode, ACK One fleets, ACS serverless pods, Lingjun AI node pools, on Kubernetes 1.34 to 1.36
    • Latest release: Kubernetes 1.36 on ACK (May 2026); 1.37 CNCF-certified 2026-09-14
    • Next signal: Kubernetes 1.37 in the ACK version table; ack-mcp-server lifecycle tools promised as near-term in 2025, no date
    • Archetype: Fast-moving Asian AI-infrastructure cloud
    • Evidence grade: A. Nearly every score rests on the English yearly release notes, version policy, limits, fee and SLA pages read this run; say-do and compliance evidence is thin and fee history was not recovered.

    5. Credibility: 18.0 / 25

    CriterionScoreBasis
    Cadence4.5Monthly English release notes since 2017 and a published version table with end-of-support dates
    Roadmap transparency3Dated release notes but no public roadmap; some detail only on Chinese pages
    Say-do3Few dated promises: version-timing policy kept for 1.31 to 1.36; MCP server near-term tools still missing after 12 months
    Velocity4.5Several substantive features most months: Auto Mode, DRA, inference gateway, hybrid node pools, Argo cluster
    Lifecycle stability312-month windows from 1.31, forced updates, no extended support; dedicated clusters retired and serverless renamed twice

    Say-do record, 2023 to 2026: 3 items 2023-2026: version policy (new minors about two weeks after the first patch) kept for 1.31 to 1.36; ack-mcp-server lifecycle tools promised as near-term in 2025-09 still pending; enterprise RBAC for the MCP server open-ended. No public roadmap; first-pass ledger of 9 shipped items (7 routine versions with invented dates) removed.

    Cost of staying supported2.512 months per minor from 1.31, forced updates one month after notice, no paid extended support

    Security record of the product itself: No ACK-specific cross-tenant or managed-control-plane flaw found for 2023-2026 (NVD, ACK advisories, web search); upstream add-on issues such as IngressNightmare (CVE-2025-1974) have ACK advisories requiring customer upgrades. No deduction.

    AI say-do: 2 announced (MCP lifecycle tools, MCP RBAC), 0 GA, 2 pending, 0 dropped; the AI assistant, its agent mode and the MCP server shipped without prior promises, and inference routing on Gateway API is the strongest AI workload feature.

    10. Reading

    Alibaba is turning ACK into an automated, AI-centred platform: Auto Mode nodes, Lingjun AI clusters, inference routing on Gateway API and an LLM assistant with an MCP server. The release notes show a feature or more almost every month and new Kubernetes minors within weeks, but there is no public roadmap and support windows were cut to 12 months with forced updates. Buyers get very broad capability and fleet tooling at low control-plane cost, weighed against regional reach outside Asia, sparse compliance evidence and a provider whose roadmap is opaque.

    11. Open questions and evidence caveats

    • Exact ACK release days are not published (months only); version lag is approximate and cross-checked with CNCF certification dates.
    • ACK Pro fee history and the commercial date after the 2020 preview were not recovered.
    • Compliance programmes covering ACK (C5, ISO, MLPS) were not verified in this run.
    • Region-wide incidents (Hong Kong Zone C 2022-12-18; global console and API 2023-11-12) affected cloud operations; ACK impact not stated.
    • Several AI and product details exist only on Chinese pages, including the MCP server README.
