Differences vs Huawei
- Capability scope differs: Glue provides serverless ETL jobs, crawlers, and catalog integration, while CDM is migration-oriented data movement/ETL often paired with other Huawei analytics services.
- Pricing model differs: Glue pricing is resource/time and request based (for example job capacity runtime and catalog operations), while CDM pricing is tied to purchased migration compute specifications and duration.
Migration to Huawei
- Map discovery/assessment, replication pipeline, and cutover checkpoints with rollback criteria. For AWS AWS Glue, the direct Huawei equivalence layer is CDM; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.
- Use a composed Huawei migration pattern where needed: CDM + DLI + DWS. Treat CDM as the core equivalent capability and use the additional services to cover integration, security, observability, and governance gaps.
- Pricing model difference: AWS usually bills migration task/runtime and transferred data plus source/target infrastructure costs; Huawei usually bills MGC governance plus SMS/OMS/CDM/DRS runtime, migrated volume, and network/resource consumption. Recalculate TCO with peak load, request volume, retention period, and cross-region/interconnect traffic before production migration.
