Data Migration Techniques

Summary

Moving large volumes of data into the cloud — online transfer for smaller datasets, offline/physical transfer devices for very large ones, and continuous replication for minimal-downtime cutovers.

• 1Learn when a physical data transfer device becomes faster than transferring over the internet.
• 2Understand the trade-off between a one-time bulk transfer and continuous replication before cutover.
• 3Practice estimating transfer time for a hypothetical dataset size given available bandwidth.
