11 Modern, cost-effective systems Modern IT architectures, particularly those built on microservices and application programming interfaces (APIs), enable airlines to replace outdated, monolithic systems with more agile and cost- effective solutions. These systems can be scaled up or down based on real-time demand, reducing unnecessary overhead. Additionally, by breaking down silos and ensuring better integration across all components of the airline's operations, these modern systems help in streamlining workflows, reducing redundancy and ultimately lowering operational costs. In essence, by investing in modern IT systems, airlines are not only positioning themselves to capture more revenue through smarter data-driven strategies but also significantly driving down costs through greater efficiency and scalability. This dual approach is crucial for maintaining profitability and competitiveness in the evolving aviation industry. Microservices and APIs The transition to a microservice architecture and the extensive use of APIs is a major technological trend in the airline industry. Microservices break down complex applications into smaller, independent services that can be developed, deployed and scaled independently. This modular approach enables airlines to innovate more quickly, reduce development cycles and integrate new functionality with minimal disruption. APIs further facilitate seamless integration between different systems and platforms, allowing airlines to connect with external partners such as travel agencies and payment providers, or even other transportation or service providers to enhance the overall customer experience.
