In this post, we show you how to migrate an Oracle database to an Amazon RDS for Oracle DB instance. The solution uses Oracle Data Pump for initial data load and Oracle GoldenGate Microservices Architecture installed on an Amazon Elastic Compute Cloud (Amazon EC2) instance as the Oracle GoldenGate hub for change data capture.

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.

With AWS DMS homogenous migration, you can migrate data from your source database to an equivalent engine on AWS using native database tools. In this post, we show you an example of a complete homogeneous migration process and provide troubleshooting steps for migrating from PostgreSQL to Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL.

In this post, we show you how to use advanced replication features between MySQL-compatible databases such as Amazon Aurora MySQL-Compatible Edition clusters or Amazon Relational Database Service (Amazon RDS) for MySQL instances. We discuss two replication capabilities in Amazon RDS and Amazon Aurora: multi-source replication and replication filtering. Multi-source replication is supported only in Amazon […]

Cloud computing has changed almost every business and industry by changing the delivery and consumption model. With the Cloud, businesses no longer need to plan for and procure servers and other IT infrastructure weeks or months in advance. This allows more flexibility and reliability, increased performance and efficiency, and helps to lower IT costs. The […]

This is the first in a two-part series of posts on how to migrate a multi-TB database to Amazon Relational Database Services (Amazon RDS) Custom for SQL Server. Amazon RDS Custom for SQL Server is a managed database service that automates setup, operation, backups, high availability, and scaling of databases while granting access to the […]

One of the steps in migrating a database to the cloud involves transferring existing data from the source (on premises) to the target (cloud). For medium and large databases, such as those ranging from hundreds of gigabytes to 5 terabytes, speed of data transfer matters. One of the challenges is to minimize the downtime of […]

While migrating workloads from the Azure Cloud to the AWS Cloud, organizations explore optimal, managed database services to replace their Cosmos DB databases. As NoSQL databases become more ubiquitous, especially those that support the Apache 2.0 open-source MongoDB APIs, our customers often choose Amazon DocumentDB because it’s a scalable, highly durable, and fully managed database […]

Migration of SAP ASE (previously known as Sybase ASE) to Amazon Relational Database Service (Amazon RDS) for SQL Server is heterogeneous in nature and consists of major phases such as pre-migration assessments, conversion of database schema, and post-migration validation. Because the migration process involves code conversion, it involves the crucial task of validating the converted […]

As part of this blog series, we previously covered database object validation for migrations from SAP ASE (previously known as Sybase ASE) as source to target databases like Amazon Relational Database Service(Amazon RDS) for SQL Server, Amazon RDS for MySQL, Amazon RDS for MariaDB, or Amazon Aurora MySQL-Compatible Edition. In the final post of this […]
