Create self-managed replicas for an Amazon RDS for Db2 instance for read scaling and disaster recovery

In this post, we explain how to use RDS Db2 Snapshot and AWS Database Migration Service (AWS DMS) to create cross Region replicas for your RDS for Db2 DB instance. If you want to use this replica for read scaling, there needs to be logic built at the application layer to direct only read traffic to the replica.

Resolving non-responsive connection issue to on-premises Oracle multitenant architecture database having local listeners behind firewall from the cloud

Oracle Multitenant Architecture uses a container-based architecture specifically designed for the cloud. It enables the Oracle database to function as multitenant container database (CDB) where application databases are created as pluggable databases (PDB) inside the container database (CDB). A PDB is a collection of schemas, schema objects and non-schema objects, and self-contained for an application […]

How Phreesia replicated a 30 TB SQL Server database to Amazon S3 with AWS DMS

In this post, we discuss how Phreesia used AWS DMS to replicate their on-premises database to AWS in an effective and cost-optimized manner. Because of the database’s large size and complex data structure, properly tuning the AWS DMS configuration was critical to minimize the migration duration and cost. We outline the fine-tuning techniques that were applied to optimize the AWS DMS task settings, instance size, IOPS provisioning, and table mappings. Applying these performance optimizations allowed Phreesia to develop a migration strategy to move this 30 TB database to Amazon S3 in just 2 days without disruption to production workloads.
