Customer Challenge<\/h2>\n

Dianomi\u2019s advertising platform was hosted on Rackspace. Dianomi wanted to migrate their entire platform, which included 20 Centos VMs and MySQL database, to AWS to reduce costs, improve reliability, support, and modernize their DevOps pipeline. All AWS infrastructure was to be deployed and managed via Terraform. Dianomi\u2019s 1Tb MySQL platform database had to be replicated to AWS ensuring all changes were streamed with a maximum lag of 15 seconds. Finally, Dianomi\u2019s customers must not experience any outages or downtime during the migration project.<\/p>\n

Proposed Solution<\/h2>\n

Elixirr Digital worked closely with Dianomi\u2019s team to understand the existing platform architecture and current scaling challenges to propose an architecture that would support the current workload but with flexibility to allow Dianomi to enhance and scale post the migration project. The Rackspace environment would be replicated on a 1:1 basis to ensure seamless functionality of the service within AWS. Elixirr Digital proposed a DEV and PROD environment in separate AWS accounts fully managed and configured via Terraform. Ansible playbooks to configure and automate application deployment. Over 70 alerts and monitors were to be setup in CloudWatch so Elixirr Digital’s support team would be notified of any problems with the system within AWS.<\/p>\n

Data Migration<\/h2>\n

The most challenging aspect of the project was to stream and replicate the MySQL database from Rackspace in UK to the new AWS RDS MySQL database in North Virginia while maintaining a 15 second lag so upon cutover to the new environment Dianomi\u2019s customers wouldn\u2019t experience errors.<\/p>\n

Third Party applications and solutions used.<\/strong><\/p>\n

Open source tools myDumper and myLoader were used to take a full database export and AWS DMS was used to replicate live changes. This solution required extensive testing and customization before the optimal configuration was arrived upon. Terraform and Ansible were used to create and configure each environment in AWS.<\/p>\n

Successful Migration and Hypercare<\/h2>\n

After rigorous testing Elixirr Digital successfully migrated Dianomi\u2019s ad platform in March 2023. No errors were reported by any of Dianomi\u2019s customers. Following migration ran our standard 2-week hypercare process where the entire project team monitor the new systems performance and triage any issues that are reported.<\/p>\n

AWS Technology Used<\/h2>\n

Dianomi\u2019s platform used an extensive range of AWS technology to support migrating 20 Virtual Machines from Rackspace to AWS. These included:<\/p>\n
