Lavik swaps Redis's DRAM for NVMe SSDs and cuts a 300-node cluster to 3 machines
Migrate Your 300-Node Redis Cluster to Just 3 Lavik Nodes
Lavik keeps application values on NVMe SSD while holding keys and metadata in DRAM, and its published benchmark reports 1.14 million GETs per second — 12.5% faster than Redis on DRAM. The pitch: replace 300 Azure Redis VMs with two storage-dense L16as_v4 data nodes plus a small voter, cutting the monthly bill from $27,594 to $2,101, a 92.4% drop, for workloads where retained state grows faster than request volume.
This is the architectural result that makes consolidation worth considering: NVMe-backed capacity can come with higher throughput than an in-memory server, rather than forcing the application to exchange performance for lower storage cost.
