Overview
NATS 2.14.2 on Ubuntu 26.04 with Free Maintenance Support by ATH Infosystems
NATS on Amazon (AWS) Marketplace delivers a high-performance, event-driven messaging layer for distributed systems running on AWS. The architecture is designed to be lightweight, scalable, and secure, enabling asynchronous communication between microservices, applications, and edge workloads.
Why Use NATS on AWS Marketplace?- Extremely low latency and high throughput
- Lightweight footprint that reduces EC2 costs

Security is built into every layer:
- TLS encryption for all client and server connections
- Authentication using users, credentials, or tokens
- Fine-grained authorization using subject-level permissions
- Network isolation using VPCs, subnets, and security groups
- Single-node deployment for development and testing
- Clustered deployment for production workloads
- Multi-AZ architecture for high availability
- Edge-to-cloud architecture using distributed NATS nodes
- Minimal CPU and memory footprint
- Fast startup and recovery times
- Simple configuration and management
- Stateless core enables easy rolling updates
- Observability through metrics and logs
- Extremely low latency
- High throughput
- Simplified scaling and fault tolerance
- Reduced infrastructure and operational costs
- Secure, cloud-native design
- Flexible for edge, cloud, and hybrid environments
Highlights
- Ultra-low latency, high-throughput messaging
- Lightweight, stateless core for fast startup
- Secure TLS, auth, and subject-level access control

Dimensions summary
You pay by the hour based on the EC2 instance size you run this software on. All 21 options carry the same NATS software with maintenance support; they differ only by compute capacity. General-purpose types (t2, t3, m3, m4, m5) suit typical workloads, while t3.nano, t2.micro, and t3.micro fit light usage. Compute-optimized types (c3, c4, c5) target processing-heavy needs. Memory-optimized types (r3, r4, r5) handle memory-intensive work. Larger instances cost more per hour. You are also billed separately by AWS for the underlying infrastructure.
Top-of-mind questions for buyers
You pay for each hour an instance runs. One hour equals one running EC2 instance of the size you chose, such as t3.medium or r5.large. Each instance you launch bills separately. The rate matches the instance type; larger types carry a higher hourly rate.
The hourly software charge applies only while an instance runs. Stopped or terminated instances do not accrue the software fee. Stopped instances may still incur AWS storage charges for attached volumes, billed separately by AWS. The software meters running time only.
The hourly rate covers the NATS software and maintenance support from the vendor. You pay AWS separately for the underlying EC2 compute, storage, and data transfer. These two charges appear together on your AWS bill but are priced independently.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
