Application rearchitect and migration using Microservices architecture for leading Australian Airline

Challenges.

• Client’s Application and End-user website was built on monolithic architecture hosted on customer’s On-premise impacting user experience; less room for scalability in existing platform
• Legacy Technology stack (Oracle UCM, SOA services for integration with external system) was used. Using existing On-premise environment would result in additional cost (procurement of tools, hardware and licenses) to support the new business requirements and features
• Monolithic Application was tightly coupled code resulted in delay in release and downtime to provide solution or break-fix

Solution.

1. Rearchitected the legacy application using microservices architecture and migrated on AWS for high available and scalable solution
2. A complete rearchitect of the existing application was done in 3 phases with AWS services (AWS ECS, Fargate, EC2, RDS, S3, DirectConnect, Route53) and web enabled user interface
3. The application designed over cloud provided agility and a flexible architecture that was able to adopt new market technologies like AEM, Java, Spring Boot.

The impact.

• Improvement in User Web booking, Web Check-In and Loyalty membership experience
• Highly Available Application with reduced downtime
• Faster Release cycles and Time to Market
• Reduced TCO
• Reduction in Customer Support Calls
