Fluent uses Amazon Aurora PostgreSQL-Compatible Edition as its high-performance OLTP database engine to process their customers’ intricate search queries efficiently. Fluent Commerce strategically combined AWS-based upgrade approaches—including snapshot restores and AWS DMS ongoing replication—to seamlessly upgrade their 32 TB Aurora PostgreSQL databases with minimal downtime. In this post, we explore a pragmatic and cost-effective approach to achieve near-zero downtime during database upgrades. We explore the method of using the snapshot and restore method followed by continuous replication using AWS DMS.

Accelerate SQL Server to Amazon Aurora migrations with a customizable solution

Migrating from SQL Server to Amazon Aurora can significantly reduce database licensing costs and modernize your data infrastructure. To accelerate your migration journey, we have developed a migration solution that offers ease and flexibility. You can use this migration accelerator to achieve fast data migration and minimum downtime while customizing it to meet your specific business requirements. In this post, we showcase the core features of the migration accelerator, demonstrated through a complex use case of consolidating 32 SQL Server databases into a single Amazon Aurora instance with near-zero downtime, while addressing technical debt through refactoring.

Restore an Amazon RDS Custom for SQL Server instance using a backup from AWS Backup

AWS Backup supports the creation of on-demand backups of RDS Custom for SQL Server instances. However, the restoration of RDS Custom for SQL Server instances through AWS Backup is not natively supported at the time of writing this post. Nonetheless, this post presents a workaround solution that enables the successful restoration of RDS Custom for SQL Server instances using AWS Backup-created backups.
