How Yieldmo Cut Database Costs and Cloud Dependencies
Summary
Yieldmo, an online advertising platform, migrated its core database infrastructure from Amazon DynamoDB to ScyllaDB to address escalating costs and achieve multicloud flexibility. Initially, DynamoDB provided simplicity and stability for processing hundreds of billions of daily ad requests with sub-second latency. However, as Yieldmo scaled, DynamoDB's expense became unsustainable, and its regional limitations hindered multicloud deployment, particularly for ad servers in Amsterdam needing to access data in Dublin. After evaluating alternatives like caching layers and Aerospike, Yieldmo chose ScyllaDB due to its DynamoDB-compatible API (Alternator), cross-cloud support, and lower operational costs. The migration involved moving multiple terabytes of data across five AWS regions over several weeks, resulting in a 50% reduction in database costs and modest latency improvements, while maintaining reliability and gaining crucial deployment flexibility.
Key takeaway
For AI Architects and MLOps Engineers designing high-throughput, low-latency systems, consider ScyllaDB as a viable alternative to DynamoDB. If your organization faces escalating DynamoDB costs or requires true multicloud deployment flexibility, ScyllaDB's DynamoDB-compatible API can significantly reduce migration effort while cutting database expenses by approximately 50% and improving latency. Evaluate i4i EC2 instance types for optimal performance with ScyllaDB.
Key insights
Migrating from DynamoDB to ScyllaDB can halve database costs and enable multicloud flexibility for high-throughput, low-latency workloads.
Principles
- Geographic latency dictates database placement for optimal performance.
- Database indexing strategy impacts memory requirements and cost.
- DynamoDB API compatibility simplifies migration to alternative databases.
Method
Yieldmo migrated historical data using ScyllaDB's Spark-based tool, paused ML batch jobs, and replayed recent writes via Kafka, then validated performance across regions before promoting ScyllaDB to primary status.
In practice
- Evaluate database alternatives for multicloud support and cost efficiency.
- Utilize DynamoDB-compatible APIs to minimize code changes during migration.
- Plan for data storage needs and TTLs when scaling self-managed databases.
