Cloud-native modernization of large-scale automotive workloads on AWS
An enterprise automotive organization initiated its cloud journey with a lift-and-shift migration to AWS, which led to increasing operational inefficiencies over time. In 2024, a strategic decision was made to modernize workloads across 40 development teams to reduce costs, improve scalability, and enhance sustainability.
AWSMigrationServerlessThe Challenge
Despite adopting microservices, several high-traffic components evolved into large, complex services with growing technical debt. These services slowed feature delivery, increased operational overhead, and created an imbalance between development and operations, ultimately limiting agility and scalability.
Our Solution
A cloud-native target architecture was defined in collaboration with AWS and specialized partners. Each development team migrated workloads into dedicated AWS accounts, enabling greater autonomy and service flexibility. Standardized CI/CD pipelines were introduced using AWS CodePipeline, AWS CodeBuild, and AWS CodeDeploy, supporting blue/green deployments. Teams deployed services on Amazon ECS using either EC2-based or AWS Fargate models, with the option to adopt serverless architectures for new workloads. This approach reduced infrastructure complexity, improved deployment speed, and optimized cost efficiency compared to the previous model based on large auto-scaling groups and per-component load balancers.
Results & Impact
Novalo Technologies supported a key development team in modernizing a service responsible for approximately 20% of total traffic. The migration enabled geographic expansion into Japan and South Korea and reduced monthly AWS costs from $31,000 to $6,100 through the adoption of ECS on Fargate, AWS Lambda, and a modernized architecture. The success of this initiative accelerated broader modernization efforts and renewed focus on innovation across the organization.
