We present and compare hardware and system architectures for databases that take advantage of parallelism. First, we state the problem and identify the main comparison criterions (price, performance, extensibility, data availability). Then, we review the major architecture classes (shared nothing, shared everything, shared disks, hybrid) and discuss their advantages and drawbacks for different kinds of workloads.
