Conductor vs Express Gateway: What are the differences?

# Introduction
Key differences between Conductor and Express Gateway are outlined below.

1. **Architecture**: Conductor follows a microservices architecture, allowing for scalability and flexibility in managing multiple services, while Express Gateway is built on Node.js and Express.js, providing a lightweight and adaptable gateway for managing APIs.
2. **Scalability**: Conductor offers horizontal scalability by enabling the distribution of services across multiple nodes, while Express Gateway scales vertically through a single node setup with the option to add more instances.
3. **Configuration**: Conductor uses a declarative JSON format for configuration, making it easy to define workflows and dependencies, whereas Express Gateway utilizes a plugin-based system for configuration, providing more flexibility in customizing the gateway functionalities.
4. **Plugins**: Conductor has a limited number of built-in plugins for extending functionality, whereas Express Gateway offers a wide range of community-supported plugins for adding features like authentication, rate limiting, and logging.
5. **Monitoring**: Conductor provides basic monitoring capabilities for tracking service performance and resource usage, while Express Gateway integrates with third-party monitoring tools like Prometheus and Grafana for more advanced monitoring and analytics.
6. **Community Support**: Conductor has a smaller community compared to Express Gateway, resulting in fewer resources and community-driven plugins available for support and troubleshooting.

In Summary, these key differences highlight the architectural, scalability, configuration, plugin, monitoring, and community support disparities between Conductor and Express Gateway.
