When should teams adopt NATS, and when should they avoid it?

When considering the adoption of NATS (Neural Autonomic Transport System), teams should evaluate specific use cases and requirements to determine if it aligns with their operational needs. Below are guidelines on when to adopt and when to avoid NATS:

When to Adopt NATS

• Microservices Architecture: NATS excels in microservices environments where services need to communicate reliably and asynchronously.
• High Throughput and Low Latency: If the application demands high throughput and low latency messaging, NATS is a strong choice due to its lightweight design.
• Cloud-Native Applications: For teams implementing cloud-native solutions, NATS can easily integrate with container orchestration systems like Kubernetes.
• Event-Driven Systems: NATS is ideal for event-driven architectures, where services are triggered based on events rather than direct requests.
• Scalability Requirements: If scalability is a significant consideration, NATS can handle high numbers of connections and message traffic effectively.

When to Avoid NATS

• Complex Routing Needs: If the application requires complex routing or message-processing patterns, other messaging systems may be more suitable.
• Guaranteed Delivery: While NATS provides at-least-once delivery semantics, systems requiring strict message delivery guarantees may need alternative solutions.
• Legacy Systems Integration: Teams that need to integrate with legacy systems may find compatibility issues with NATS.
• Data Persistence Requirements: NATS does not provide built-in data persistence. Applications needing long-term message storage should consider alternatives.
