Challenge to Triumph: Exploring Real-World High Availability in SQL Server Environments
summary
A large Canadian customer migrates ~3–400 SQL servers into AWS and builds ~300 two‑node EC2 clusters across two availability zones using SIOS DataKeeper to do block‑level, synchronous or async replication and Windows failover clustering for HA The setup replaces Always On with DataKeeper Cluster Edition and standard edition SQL instances, cuts SQL licensing and instance costs dramatically — typically up to 70% license savings and one project showing ~90% saved — and runs with 24/7 support and a 97% satisfaction rating
