12-8: Database Strategy & Polyglot Persistence
The engineering fragmentation cost of running 6 different database technologies vs the efficiency of standardization.
🎯 What You'll Learn
- ✓ Quantify Polyglot Persistence overhead
- ✓ Model the migration CapEx of leaving Oracle
- ✓ Determine Read Replica economics
The Fragmentation of Data Stores
Polyglot Persistence—using the "right database for the job" (MongoDB for documents, Redis for cache, Neo4j for graphs, Postgres for relations)—is architecturally beautiful but operationally ruinous.
Every new database technology introduced to the enterprise requires a specialized Site Reliability Engineer (SRE) to manage patches, backups, and failovers. The payroll cost of maintaining expertise in 6 disparate databases far outstrips the latency benefits.
Standardization drives margin. An organization that mandates PostgreSQL for 95% of workloads structurally minimizes its Operational Expense (OpEx) for DevOps and training.
The total cost of licensing, cloud instances, and SRE payroll per DB technology.
The time required to enact a breaking data schema change without downtime.
Consolidate the enterprise database sprawl.
