  33. 33

    Note · Glossary

    VM — Virtual Machine

    Virtual machine; an IaaS boundary closer to operating-system ownership.

  34. 34

    Note · Glossary

    IaaS — Infrastructure as a Service

    Infrastructure as a Service; the user owns more runtime and patching responsibility.

  35. 35

    Note · Glossary

    PaaS — Platform as a Service

    Platform as a Service; more runtime is managed, but identity, network, and data still need design.

  36. 36

    Note · Glossary

    RBAC — Role-Based Access Control

    Role-Based Access Control for least-privilege authorization.

  37. 37

    Note · Glossary

    Network Security Group controlling inbound/outbound rules at subnet or NIC scope.

  38. 38

    Note · Glossary

    Domain Name System; Private Endpoint success often depends on correct private resolution.

  39. 39

    Note · Glossary

    RPO — Recovery Point Objective

    Recovery Point Objective; the acceptable data-loss window measured in time, not the time needed to restore service.

  40. 40

    Note · Glossary

    RTO — Recovery Time Objective

    Recovery Time Objective; target time to restore a usable service.

  41. 41

    Note · Glossary

    RU — Request Unit

  42. 42

    Note · Glossary

    RAG — Retrieval-Augmented Generation

    Retrieval-Augmented Generation; retrieval hits do not equal authorization or answer correctness.

  43. 43

    Note · Glossary

    STT — Speech to Text

    Speech to Text; language, noise, and privacy boundaries matter.

  44. 44

    Note · Glossary

  45. 45

    Note · Glossary

  46. 46

    Note · Glossary

  47. 47

    Note · Pitfall

    Stopped is not deallocated

    A stopped VM may still keep billable resources; verify deallocation plus disks, IPs, and backup costs.

  48. 48

    Note · Pitfall

    Budgets are not hard caps

    Budget alerts do not replace quotas, policies, automated shutdown, and cost review.

  49. 49

    Note · Pitfall

    Private Endpoint does not automatically close public access

    Also check service public-network settings, DNS resolution, authorization, and client paths.

  50. 50

    Note · Pitfall

    Replication is not backup

    Replication can sync deletion or corruption; backup, retention, and restore drills are separate capabilities.

  51. 51

    Note · Pitfall

    Vector indexes are not transactional databases

    Retrieval indexes serve recall; they do not replace systems of record, authorization, or audit logs.

  52. 52

    Note · Pitfall

    RAG is not authorization

    Apply permission filters before and after retrieval; a citation does not mean the user may view it.

  53. 53

    Note · Pitfall

    Model confidence is not a security threshold

    Security decisions need verifiable policy, audit, and escalation paths, not model tone.

  54. 54

    Note · Pitfall

    Offline F1 is not business outcome

    Explain offline metrics separately from drift, cost, false positives, UX, and online experiments.

  55. 55

    Note · Decision note

    Draw identity boundaries first

    Mark people, service principals, managed identities, data-plane permissions, and audit points before compute choices.

  56. 56

    Note · Decision note

    Review cost and resilience together

    Availability zones, backups, and queues can support resilience when failure modes and recovery are validated. Caches primarily improve performance and add invalidation and consistency risks; they do not automatically improve availability.

  57. 57

    Note · Decision note

    AI needs a data contract

    RAG, evaluation, and agent tools depend on clear sources, fields, permissions, retention, and failure modes.

  58. 58
