Smooth Takeoff: Modernizing a Legacy Ramp Handling System

Challenges.

Existing legacy application was built on Sybase and Power builder and was becoming a maintenance challenge due to its outdated technology, expired support for the products and complexities in its monolithic implementation. The client was facing the following challenges: 

• Legacy System Limitations: The client's existing on-premise ramp handling system lacked agility, flexibility, scalability, integration capabilities, and real-time data access.
• Manual Processes: Manual data entry and paper-based workflows hampered efficiency and increased the risk of errors.
• Limited Visibility: Lack of real-time data insights hindered proactive decision-making and ground operations optimization.
• Slower GTM and release cycles
• Enhancements were expensive and risky 

Solution.

A complete rewrite of the existing application was done using microservices architecture and web enabled user interface. The application designed for cloud provided agility and a flexible architecture that was able to adopt technologies like Kubernetes and Angular. 

• Containerization of Ramp Handling System application 
• On-demand, Auto-scaling configuration for Worker node and Amazon Aurora Serverless 
• Building and deploying application on AWS natively for Application Modernization 
• Infrastructure as a Code All the services were launched using CloudFormation scripts 
• Provided ability to release at will 

Key features delivered through the modernized system were 

• Modularity 
• Cloud based architecture 
• MicroServices for future proofing 
• Next generation UI/UX 
• Mobile Ready 
• DevSecOps agility 

The Impact.
