We are in a Messaging Renaissance

Cloud Messaging is fastest growing segment of current messaging market. (Gartner 2013)

New requirements for IoT, mobile, big data, and microservices applications

● Legacy bloated platforms don’t work● Open source first

Massive sensor enablement wave● 20.8 billion connected things by 2020 (Gartner) ● Driving requirements for “Trusted IoT”

Messaging & The “General Problem”

๏

๏ They try to do too much‣ “Kitchen sink” mentality

๏ They don’t prioritize stability and performance‣ If it’s not fast/available enough... who cares what it does

๏ They carry too much baggage‣ Compile-time and runtime dependencies‣ Standards for their own sake

๏ Engineered for traditional on-premise computing๏ Generalize and compromise

‣ Built for specific use cases and later generalized, sometimes poorly

Why Messaging Systems Disappoint

๏ Performance๏ Simplicity

‣ Single binary‣ Text-based protocol

‣ No external dependencies ๏ Availability over anything - Dialtone๏ Small footprint & embeddable๏ Just what you need, and none of what you don’t

NATS DNA

Small Footprint

Performance - Throughput and Latency

๏ Current Throughput Performance - ~10M msgs/sec*

*https://github.com/nats-io/gnatsd/blob/master/test/bench_results.txt

“By combining NATS and Golang, the new signaling system is now able to do 10M+ concurrent connections...with an average speed improvement of 32%...which means we had successfully combined our two most important goals; scaling and speed.”

-- Dennis Mårtensson, CTO Greta.io

Latency

๏ Look closely… NATS is hugging the X axis.

๏ Where’s everyone else?

๏ Kafka, ActiveMQ, and RabbitMQ were orders of magnitude higher latency

Auto Discovery๏ Intra-cluster discovery๏ Client cluster discovery

Enterprise Messaging๏ Hosted Service๏ At-least-once delivery

(message acks + redelivery)

๏ Rate matching/limited (max in-flight messages)

๏ Replay features:‣ All available‣ Start at last/initial value‣ Time offset‣ Sequence offset

Security๏ ACL based permissions๏ Pluggable integration

with external authorization

๏ Identity-focused security enhancements

NATS at Workiva

“NATS is a masterpiece…”

Tyler Treat, Senior Software Engineer, Workiva

Microservices Examples"We opted for NATS over other message systems due to its elegant simplicity and remarkable performance — and because NATS has an exceptional potential for scalability that matches our project's ambitions.--Aaron John Schlosser, Application Developer at NextGen Leads

The simplicity and focus of NATS enables it to deliver superior performance and stability with a lightweight footprint. It has the potential of becoming the de-facto transport for microservice architectures and event driven systems in this new era.--Asim Aslam, Creator of Micro

“NATS is clearly leading the messaging technology pack when it comes to performance, scalability, simplicity, and ease of use. These metrics made it the clear choice for our development team who are busy building our next-generation call-center platform.”

--Leif Madsen - Director of Engineering, Product Development, AVOXI
