"Operational-Hybrid"
- MySQL → Aurora MySQL:storage layer 轉手到 AWS、replication / HA / backup 全部 outsource
自管 MySQL → Aurora MySQL 是 Type C operational hybrid migration — wire protocol 一致、ops 責任轉到 AWS。本文走 6 維 audit(Operational High)、Aurora storage architecture 衝擊、4-phase migration、5 production 踩雷、何時維持原路線。
- 自管 Vitess → PlanetScale:Vitess component ops outsource、加 schema workflow shift
自管 Vitess → PlanetScale 是 Type C operational hybrid — Vitess component(VTGate / VTTablet / VReplication / VSchema)ops outsource + branch workflow。本文走 6 維 audit、4-phase migration、5 production 踩雷、何時不要遷。
- Pyroscope → Datadog Continuous Profiler:profiling deployment lifecycle 各階段 operational ownership 轉手
Pyroscope → Datadog Continuous Profiler 是 Type C operational hybrid migration — pprof data model 接近、profile lifecycle 五階段(install / instrument / ingest / query / cost)的 ops ownership 從 self-host 轉到 SaaS。本文走 6 維 audit(Operational High 其他 Low)、4-phase migration(operational audit + agent parallel + tag reconcile + cutover)、5 production 踩雷(agent 重複 overhead / tag schema 不一致 / trace_id correlation 斷 / cost 突增 / retention 政策變動)、何時保留 Pyroscope(資料主權 / 內網 / OSS-first / cost sensitive)
