NATS¶

NATS. Core Features¶

• Simplicity and speed – NATS is written in Go and optimized for minimal latency and high throughput, capable of handling millions of messages per second.
• Lightweight – Minimal resource requirements make it ideal for containers, edge devices, and cloud environments.
• Support for multiple messaging models:
  • Pub/Sub – publishers send messages to subjects, subscribers receive them.
  • Request/Reply – synchronous exchange, with the message confirmed by a corresponding reply to the publisher.
  • Queue Groups – concurrent processing: queue groups are defined by the application and its subscribers, not by server configuration.
• Scalability and resilience – NATS supports clustering, enabling the creation of fault‑tolerant and geographically distributed systems.
• Security – TLS support, authentication (tokens, username/password, JWT), and role‑based authorization.
• Language support – Official and third‑party client libraries are available for many languages: Go, Java, Python, JavaScript (Node.js), C#, Rust, Ruby, and more.

Deployment Features¶

• Installed software:
  • Docker
  • NATS Server

The web interface will be accessible at: https:nats{Server_ID_from_Invapi}.hostkey.in.

Getting Started After Deploying NATS¶

After paying for the order, a notification will be sent to the email address provided during registration, indicating that the server is ready. It will include the VPS IP address, as well as a login and password for connection. Equipment management is handled by our clients through the server control panel and API — Invapi.

Authorization data can be found either in the Info >> Tags tab of the server control panel or in the email sent to you:

• Link to the NATS web panel: the tag :fontawesome-solid-tags: _webpanel_;
• Login: root;
• Password: delivered in the email when the server is ready after software deployment.

On the left side of the screen, there is a menu with various categories that allow the user to obtain information about the system status:

• General — general information about the server.
• JetStream — data about JetStream, the NATS extension for storing and processing message streams.
• Connections — a list of connections to the server.
• Accounts — information about user accounts.
• Account Stats — statistics about accounts.
• Subscriptions — subscriptions to message topics.
• Routes — routes for transmitting messages.
• LeafNodes — information about leaf nodes (possibly in the context of cluster architecture).
• Gateways — gateways for connecting to other systems.
• Raft Groups — Raft groups used to ensure consistency in cluster configurations.
• Health Probe — system health check.
• Expvar — export variables for monitoring.
• Help — help and documentation.

This interface is intended for administrators and developers who monitor the uptime and performance of the NATS system.
