Background

Dietbk MMI Tech migrated its .NET applications from restrictive shared hosting to AWS EC2 Windows with Rambunct. The move improved performance, reduced support overhead, enabled DevOps automation, and lowered infrastructure costs by 45%.

The Challenge

The existing infrastructure lacked the flexibility and robustness required for modern enterprise needs. Critical limitations in control, scalability, and resilience posed significant risks to performance, configurability, and business continuity.
  • Limited control over Windows Server/IIS blocked enterprise configurations​.
  • Unable to install required Windows services or extensions​.
  • Unscalable environment affected peak performance​.
  • Backup and disaster recovery options were minimal or missing.

Our Solution

To address the limitations of the legacy setup, a secure, scalable, and fully customizable AWS-based Windows environment was deployed. This new architecture enables enterprise-grade configurations, improves performance, and ensures operational visibility and compliance.
  • Designed a secure and scalable EC2 Windows environment
  • Enabled custom services, app pools, and Windows tasks
  • Integrated ALB, RDS, S3, CloudFront for complete hosting stack
  • Implemented CloudWatch and Systems Manager for full visibility and compliance

The Result

The new AWS-based solution delivered significant improvements in performance, reliability, and operational efficiency. With modern DevOps integration and full administrative control, the organization achieved greater agility, reduced maintenance burdens, and ensured high availability.
  • 85% improvement in application performance​.
  • 99.8% uptime with automated failover​.
  • 70% reduction in support overhead​.
