Tgix enhanced MLA’s resilience by implementing AWS disaster recovery for secure, continuous operations.
The Modern Language Association (MLA) is a professional organization dedicated to promoting the study and teaching of language, literature, and cultural studies, best known for its widely used MLA style of scholarly writing and citation.
MLA’s core operations relied on digital assets in AWS, but lacked a comprehensive disaster recovery (DR) strategy, posing risks of data loss, service outages, and operational disruption.
Tgix designed and implemented a phased DR strategy leveraging an alternate AWS region. This involved near-real-time replication of EC2 instances via AWS Elastic DR, daily snapshots of EBS volumes and AMIs, and cross-regional read replicas for RDS databases. High availability was ensured with Multi-AZ configurations and redundant network components. The DR site infrastructure mirrored the primary environment with pre-provisioned ALBs, VPN servers, and SSL certificates. Meticulously planned and documented failover processes included a detailed runbook and DNS failover with Amazon Route 53.
Successful DR tests demonstrated robust preparedness for failures, significantly enhancing service resilience and ensuring critical systems are recoverable within defined Recovery Point Objectives (RPO) and Recovery Time Objectives (RTO). The solution was cost-effective, scalable, and designed for continuous operational reliability. Tgix also provided ongoing AWS Cloud Managed Services to MLA for over 8 years, achieving up to 50% cost savings in non-production environments through automation and Reserved Instance strategies.
