PARTING THE CLOUDS: THE RISE OF DISAGGREGATED SYSTEMS (47 MINUTE VIDEO)

Summary from the TLDR Data newsletter

Cloud databases are increasingly separating stateless compute from shared storage to improve elasticity, failover, and pay-per-use economics. The tradeoff is remote I/O latency and bandwidth, so systems such as Aurora, AlloyDB, DSQL, PolarDB, and TaurusDB lean on buffering, prefetching, pushdown, RDMA/CXL, and careful log/storage design.
