dealing with Orchestrate-Execute Architecture
Friend Link for Non-members π
In modern enterprise applications, especially in complex domains like the airline industry, where systems require high availability, integration with multiple external services, and management of diverse user workflows, the Orchestrate-Execute microservice architecture emerges as an ideal solution. This architecture pattern brings modularity, flexibility, and clarity to microservice ecosystems, especially when dealing with legacy systems, third-party APIs, and distributed data stores.
In this article we will explore a real-world example involving an airline based application that implements various workflows like point redemption, user profile management, voucher qualification, OTP sending, and more. The Compose-Base pattern has been adopted to address both technical and business needs effectively.
