Successful Cloud Migration Enables Cost Reduction and Performance Optimization for Client's Application Stack.


This case study focuses on a client with a complex application stack consisting of 26 different applications hosted on individual Oracle databases. However, maintaining the on-premises development and testing instances proved to be cumbersome and expensive. The client sought a solution to migrate their non-production environment to the cloud.


The client faced challenges in managing the infrastructure costs associated with maintaining the on-premises development and testing instances. The individual Oracle databases increased complexity and ownership costs. The client needed to optimize their infrastructure and reduce expenses.


To address the client’s challenges, a solution was proposed in partnership with AWS. The following steps were taken to migrate the non-production environment to the cloud:

S3 drive setup: Production databases were copied from on-premises to AWS using an S3 drive, enabling secure and efficient data transfer.

Oracle database and application stack configuration: Oracle databases and the associated application stack were set up and configured within the AWS cloud environment to ensure seamless functionality.

Defined end-to-end process: A comprehensive process was established to regularly refresh AWS databases with copies of the on-premises production databases, maintaining up-to-date non-production environments on AWS.


The implemented solution yielded positive outcomes for the client:

Leveraging puppet scripts and automation: Puppet scripts and automation simplified the provisioning of new instances on AWS, streamlining environment setup and management.

Auto-scaling feature of AWS: Utilizing AWS’s auto-scaling feature ensured optimal performance by dynamically adjusting resources based on demand, enhancing application responsiveness.

Reduced cost of ownership: Migrating the non-production environment to the cloud significantly reduced infrastructure costs, providing cost savings and a flexible cost model.


The successful migration of the client’s non-production environment to the cloud using AWS offered a cost-effective and efficient solution. The client benefited from simplified environment management, optimal performance through auto-scaling, and reduced ownership costs. By embracing the cloud, the client achieved their goals of optimizing infrastructure and reducing expenses.
