AWS re:Invent 2022 - Build scalable multi-tenant databases with Amazon Aurora (DAT318)

Summary

Anam Jangshe, a product manager on the Aurora team at AWS, and Peter Fine, a software engineer at VMware, discuss building scalable multi-tenant databases with Amazon Aurora.
Aurora is a fully managed MySQL and Postgres compatible relational database built for the cloud, offering high performance, availability, and cost-efficiency.
Key considerations for multi-tenant databases include isolation, scale, cost, and operational complexity.
Aurora provides various isolation levels, from single-tenant clusters to multi-tenant clusters with schema or table-level isolation.
Aurora's architecture allows for scaling storage and compute independently, with up to 16 low latency read replicas and Aurora Global Databases for cross-region deployments.
Aurora Serverless V2 offers auto-scaling between minimum and maximum capacities, reducing costs and operational complexity.
Fast database clones in Aurora allow for quick tenant redistribution with minimal cost.
Aurora offers monitoring capabilities through CloudWatch metrics, RDS enhanced monitoring, Performance Insights, and DevOps Guru.
VMware's experience with Aurora involved consolidating 166 self-managed MySQL databases into 92 Aurora clusters, resulting in cost and operational efficiency.
Peter Fine shares VMware's journey, challenges, and benefits of migrating to Aurora, including improved performance, reliability, and cost savings.

Aurora's separation of storage and compute layers provides high availability and durability, as well as cost savings by scaling storage automatically and only charging for used capacity.
Aurora Serverless V2's in-place scaling and fine-grain increments ensure databases are not over-provisioned, aligning closely with workload demands.
Amazon RDS Proxy helps manage high connection environments by pooling and sharing database connections, improving database performance and reducing failover times.
VMware's migration to Aurora showcases real-world benefits, such as reduced CPU usage, improved performance, and cost savings, highlighting Aurora's effectiveness for large-scale, multi-tenant environments.
The transition to Aurora allowed VMware to shift from reactive maintenance to strategic projects, emphasizing the operational benefits of managed database services.
The talk suggests that organizations with high connection environments or those looking to improve multi-tenant database management should consider Aurora and RDS Proxy for their scalability, performance, and cost benefits.
