Rapid Growth Leads to a Spiraling Infrastructure
LIZYs car leasing service has grown rapidly since its 2019 launch. The company serves business and corporate customers and focuses primarily on leasing second-hand electric vehicles. It wanted to disrupt the existing leasing market, which relied on bureaucratic processes that took a long time to complete, by offering a transparent and wholly digital leasing service.
The rapid success meant LIZY had to expand its infrastructure quickly, sometimes without following cloud best practices. Over time, performance degraded, with cold starts and complex dependencies slowing down deployments. Security and user management also needed strengthening. An internal project stalled, so LIZY turned to AWS Partner Necko Technologies.
- Reduction in operating costs
- 50%
- Performance improvement
- 400%
- Faster deployments
- 75%
It was really instructive to have Necko’s experts looking at what we did and advising on how to improve our architecture.
Building a Right-Sized Architecture and Improving Security
Necko worked closely with LIZY to modernize its systems and improve both customer-facing and internal applications.
Key Recommendations
- Infrastructure as Code: Adopted AWS CDK for defining resources and improving consistency.
- Container Modernization: Migrated from Elastic Beanstalk to Amazon ECS with AWS Fargate for better control and easier dependency management.
- Cost Optimization: Moved workloads from DynamoDB to Amazon S3 where appropriate, and shut down unused compute resources.
- Security Enhancements: Introduced individual developer accounts for better access control and adopted AWS Secrets Manager for secure credential management.
Smooth Collaboration
Communication was seamless, with ongoing Slack discussions and both remote and on-site support.
Outcomes: Performance Gains and Cost Savings
The new AWS architecture brought measurable improvements:
- 50% cost reduction: Monthly expenses dropped through resource optimization and service right-sizing.
- 400% performance boost: Faster website and backend systems (CRM, finance engine).
- 75% faster deployments: Cold starts reduced from 40 minutes to 10 minutes.
LIZY’s tech team is now better positioned to evolve its architecture and deliver new features confidently.
We are now in a better place to continue to evolve our architecture for future needs. Thanks to Necko, we’re much more confident and happy working on AWS.
