Migration of Legacy Ramp Handling System to Micro-Services and Serverless Architecture
Overview.
The system was designed to enable users to harvest the unique service values which are well known in the industry as well as increase the serviceability to Airlines, Airport and other stakeholders in the airport ecosystem. Key features for clients delivered were
Modularity Cloud based architecture MicroServices for future proofing Next generation UI/UX Mobile Ready DevSecOps agility
Existing legacy applications were built on Sybase and Power builder and was becoming a maintenance challenge due to its outdated technology, expired support for the products and complexities in its monolithic implementation.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 application was very rigid in making changes
Enhancement were expensive and risky
Slower GTM and release cycles
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
The impact.
Infrastructure cost reduction by 70%
Built in-log analytics and monitoring using cloud native services
Better user experience and high observability
Enabled high availability, resiliency and optimization for the new application
Improved performance of the systems
Platform engineering approach to bring Agility in new system
