Why migrate Oracle to Amazon Aurora MySQL?

Running Oracle databases in an on-premises environment is often a challenge, things like increasing license and maintenance fees, and the need to upgrade from older versions to avoid compliance problems are far too common. Growing companies require cost-effective databases that are fast enough to keep pace with their expanding business, and enable automated processes to replace time-consuming administrative tasks.

Modernized cloud database solutions can help address these issues. We are a leader in database cloud migration, data service management, application modernization, and delivery of solutions for new services such as analytics and Internet of Things (IoT).

We have the expertise required to help customers of all sizes successfully migrate Oracle to Amazon Aurora MySQL, and the know-how to optimize performance following cloud adoption.

We are ready to guide you through the entire migration process and help optimize your Amazon Aurora environment after cloud adoption. Together we will establish a solid database foundation on Amazon Aurora or RDS services (AWS), and leverage our unique expertise to help you integrate a wide range of AWS services to increase your business flexibility.

Determining which Database and infrastructure technology is a best fit in AWS

There are many approaches to database technology in AWS from infrastructure EC2 to managed RDS and the many flavors of database servers that can be supported here.

Key questions to ask:

  • What is your current database and infrastructure technology and what is the appropriate match in AWS?
  • What resources do you have to support your database technology in AWS? Is Aurora, RDS, or EC2 the correct approach?
  • What is your HA/DR approach and can it be mapped to AWS?
  • What is your data Egress and Ingress and how will that affect your charges?

DB Best can help you answer these questions, evaluate your current workload, and direct you to the best technology in the AWS.

Choosing which workloads to move to the cloud

We take a data-centric approach to determine which workloads are most appropriate for the cloud.  We start with data collection that gives us a profile of each workload environment such as CPU, RAM, etc. We also gather performance metrics over a period of time using our agentless DBMSys software. We also work with our customers to understand the business needs/restrictions of each workload to determine a list of potential candidates that can be migrated to the cloud.

Migrating away from your current data solution

Traditionally, this means a switch from one data platform to another. However, just switching the nameplate on the back-end DB server may not be the best solution. Some data patterns and use cases may have a better fit for a NoSQL or Data Lake solution.

DB Best Architects are trained to spot these patterns and discuss with the customer another approach that may be a better fit or be able to leverage new technology such as IoT devices.

How can I migrate terabytes of data to the Amazon cloud?

Imagine you have an 80 TB database that needs to be extracted and imported into AWS Redshift or Aurora database. Normally, it would take up to several weeks for extracting and migrating such databases over the internet. DB Best has worked with Amazon in exposing a Snowball Edge configuration option in the Schema Conversion Tool. With this feature, you can hookup a Snowball Edge device to your on-premises database, extract data and upload data to the Snowball Edge and send it back to Amazon for completing the data import process during your data warehouse migration to AWS.

DB Best Architects are trained to help you configure the Snowball Edge. Working together, we can extract and help you in completing the data transfer much faster.

Building an AWS stack with multiple layers can be time-consuming and error prone

DB Best’s architects can help you in automating the entire stack creation process with AWS’s CloudFormation templates using command line scripts. These scripts take few command line parameters and setup your VPC, subnets, ELB, Aurora clusters, EC2 and RDS instances, databases, Auto-scaling groups, creating S3 buckets and uploading data, database restores and health checks.

Automated tools accelerate cloud adoption

To help our customers migrate from Oracle to Amazon Aurora, DB Best uses the automated tools we have developed to help accelerate cloud adoption. One of the featured tools we often employ is the AWS Schema Conversion Tool (SCT), which is used to compile statistics from the source database, make recommendations on finetuning, and perform analysis to forecast how Amazon Aurora can be optimized for a customer. The AWS SCT identifies potential problem areas during migration planning, determines the possible effects on the schema conversion process, and creates a strategy to validate the data.


DB Best also has expertise using the AWS Database Migration Service (DMS) to help customers move their databases to the cloud quickly and securely. The AWS DMS supports migrations between different database platforms, such as moving from Oracle to Amazon Aurora, and helps to minimize downtime during the migration process. DB Best works with the customer DBAs to strategically plan the migration and optimize capabilities on AWS.

These are the tools that we helped Amazon build or built ourselves to help automate migration from Oracle to Amazon Aurora by analyzing all of the applications that interface with the Oracle database to confirm data conversion.

DB Best’s unique approach and methodology include performance testing and benchmark metrics we have developed to deliver consistent project success.


As part of our migration project, we offer training, support, consulting, and managed services for your MySQL solutions on Amazon Aurora, RDS, and EC2. If you don’t want to go through the hassle of maintaining the day-to-day operations of your databases and applications, be sure to check out our Operational Data Management service.
