Background
The Challenge
- Outdated Django stack and Python version leading to security and compatibility issues
- Deprecated MySQL database causing instability and performance problems
- Lack of CI/CD pipelines and standardised testing increased deployment risks
- Manual scaling and infrastructure drift added operational overhead
- Inefficient tooling and workflows reduced developer productivity
Our Solution
- Migration to Python 3.11, Django 4.2.14, and MySQL 8
- Deployment on AWS Graviton2/Graviton3-based Amazon EC2 instances
- Use of Application Load Balancer (ALB) and Auto Scaling groups
- End-to-end automation and security using GitHub Actions, AWS CodeDeploy, AWS CloudFormation, AWS WAF, AWS Secrets Manager, Amazon Inspector, and AWS Certificate Manager
- Optimised performance and observability with Amazon RDS, Amazon S3, Amazon ElastiCache, Amazon CloudWatch, and AWS X-Ray
The Result
The Rambunct architecture enabled blue-green deployments, secure secrets management, observability, and scalable, resilient infrastructure.
