NATS is a secure, high-performance messaging system for modern distributed systems. It enables seamless communication across cloud, edge, mobile, and IoT environments. Lightweight and scalable, NATS supports real-time streaming with JetStream. Ideal for microservices and beyond, it simplifies and secures system design. Use this repository.
In the IaC folder, the .yaml files that must be uploaded to the CF are the following:
Nats.yml
NatsCD.yml
VPC-NatGateaway.yml
Integrate VPC for NATS
In the VPC, resources are created with networks, subnets, routetables, and NatGateway connections, where Internet inputs and outputs are controlled.
Integrate NATS Server and NATS CI/CD for NATS
These .yml files define the structure of the NATS system, including permission settings, dependency installation, and the necessary architecture for proper operation.
Create Domain DNS in Route53 for NATS and integrate NATS Server
Creating a DNS record in Amazon Route 53 allows you to assign a custom domain name to your NATS server, making it easier to access and manage. Instead of connecting to an IP address, clients can use a readable and stable domain (e.g., nats.myapp.com), which improves maintainability and supports a dynamic infrastructure.
Real Use Cases of NATS Server
Fintech and transaction processing
Financial platforms use NATS to handle events related to transactions, such as payments, transfers, or fraud detection triggers. Due to its low latency and asynchronous nature, NATS is well-suited for systems requiring near-instant communication with eventual consistency.
Real-time data streaming and processing
With its JetStream extension, NATS supports streaming and durable message storage for systems requiring real-time processing and persistence. It is used in analytics platforms to capture event streams, maintain history, and support retries or delayed analysis without message loss.
Microservices architectures
NATS is widely adopted in modern microservices platforms where efficient inter-service communication is essential. Tech companies and cloud-native startups use NATS to asynchronously connect services using patterns like pub/sub and request/reply, enabling scalable, resilient, and loosely coupled systems.
Industrial sensors and telemetry (IoT)
In industrial environments, NATS is used to collect and distribute real-time data from sensors deployed in factories, power plants, or manufacturing facilities. Companies like GE Digital leverage it in monitoring and control systems that require low latency and high reliability. IoT devices publish data via NATS, which is then analyzed or visualized by backend services.
Lightweight and fast
NATS is extremely lightweight and optimized for low-latency messaging, ideal for real-time systems.Simple to implement
The server has minimal setup requirements, and the protocol is easy to understand. You can launch a server and start sending messages in seconds.Low resource usage
Perfect for constrained environments like embedded systems, IoT, or edge computing setups.Flexible messaging models
Supports multiple patterns: pub/sub, request/reply, queue groups, and streaming (via JetStream), making it versatile for many architectures.High availability and fault tolerance
Cluster configurations and JetStream replication ensure high availability and resilience.Built-in security
Supports authentication, role-based access control (RBAC), TLS encryption, and integration with JWTs or mutual TLS.Ideal for microservices and distributed systems It helps decouple services, improving maintainability, scalability, and system reliability.
