The goal was to modernize a legacy booking platform using an API-First approach. The current system suffered from slow integration of new services, difficulty in scaling, inconsistent API designs, long development cycles, limited visibility into system performance, and challenges in maintaining backward compatibility. The main objective was to create a more flexible, scalable, and developer-friendly ecosystem while minimizing disruption to existing services.

Standardized API Design:
• URL Structure: Implemented a consistent URL pattern: https://{componentName}.domain.com/{stage}/{version}/{service}
• Error Handling: Adopted RFC7807 with custom attributes for standardized error reporting across all services.
• Versioning: Ensured backward compatibility between versions and implemented a clear versioning strategy.
OpenAPI Contract Management:
• Centralized Storage: Stored OpenAPI contracts within source code repositories at api/description.yaml.
• Version Control: Used git tags (e.g., contract-2.2.0) for contract versioning.
• Accessibility: Provided easy access to contracts via URL, supporting retrieval by version number, branch name and git hash.

Security and Authentication:
• Implemented HTTPS-only access with IPv6 support.
• Standardized authentication mechanisms, using JWT for external calls and flexible options for internal services.
Observability and Monitoring:
• Introduced endpoints for business and performance metrics (actuator/prometheus).
• Integrated with service discovery (Consul) and metric collection (Prometheus) tools.
Infrastructure as Code (IaC):
• Separated repositories for source code and infrastructure definitions.
• Adopted containerization and cloud-native deployment strategies using Docker and orchestration tools.
Continuous Integration and Deployment:
• Implemented automated testing as part of the deployment process, including E2E tests.
• Integrated with CI/CD tools for release management and transparency.
