What are the advantages and disadvantages of Eureka?
The advantages and disadvantages of Eureka are as follows:
Advantages:
- High Availability: Eureka has the capability of clustering and load balancing, enabling a high availability service registration and discovery mechanism.
- Easy to use: Eureka offers a simple API and user interface, making it easy for developers to register and discover services.
- Eureka is designed with strong scalability, allowing for easy addition of new service nodes or new service instances.
- Flexible configuration: Eureka offers a variety of configuration options for customizing to meet different needs in various scenarios.
- Self-protection mechanism: Eureka has a self-protection mechanism that ensures service availability even in cases of network abnormalities or node failures.
Drawbacks:
- Single point of failure: By default, Eureka uses a single-node registry center, which, if it fails, will cause the entire system’s service registration and discovery function to be unavailable.
- Monitoring and fault tolerance capabilities are weak: Eureka has relatively weak monitoring and fault tolerance capabilities, lacking support for monitoring the health status of services and a mechanism for fault recovery.
- High maintenance cost: Due to the complexity of Eureka’s architecture, maintaining multiple nodes and instances increases the maintenance cost and complexity of the system.
- Strong dependency: Eureka is an open-source project by Netflix, and for applications outside of Netflix, using Eureka may require addressing some dependency issues.
