NATS

8

What is NATS?● Cloud-native message platform.

9

● Designed to natively support modern cloud architectures.


What is NATS?● Cloud-native message platform.● Highly performant.

10

● Designed to natively support modern cloud architectures.● It is fast! Can handle millions of messages per second.


What is NATS?● Cloud-native message platform.● Highly performant.● Extremely lightweight.

11

● Designed to natively support modern cloud architectures.● It is fast! Can handle millions of messages per second.● A single binary, easy to deploy without unnecessary complexity.


What is NATS?● Cloud-native message platform.● Highly performant.● Extremely lightweight.● Support for various messaging models and use cases.

12

● Designed to natively support modern cloud architectures.● It is fast! Can handle 10 million messages per second on a Macbook● A single binary, easy to deploy without unnecessary complexity.● Request/Response, Publish/Subscribe, Queues.

IoT

14

IoT● Everything is connected.

15

● Virtual representations of objects (things) in a internet-like structure.


IoT● Everything is connected.● Wireless connections between objects.

16

● Virtual representations of objects (things) in a internet-like structure.● Flexible structure.


IoT● Everything is connected.● Wireless connections between objects.● Self configured and discoverable.

17

● Virtual representations of objects (things) in a internet-like structure.● Flexible structure.● Event Driven.


IoT● Everything is connected.● Wireless connections between objects.● Self configured and discoverable.● Internet is no longer for people but also for machines.

18

● Virtual representations of objects (things) in a internet-like structure.● Flexible structure.● Event Driven.● Multiple protocols.● Multiple communication patterns.


IoT + NATS

19

IoT + NATS● Always on.

20

● Always available (dial tone), fire and forget.


IoT + NATS● Always on.● Pure pub/sub.

21

● Always available (dial tone), fire and forget.● Never assumes the audience.


IoT + NATS● Always on.● Pure pub/sub.● Clustered mode server.

22

● Always available (dial tone), fire and forget.● Never assumes the audience.● Distributed queueing across clusters, cluster aware clients.


IoT + NATS● Always on.● Pure pub/sub.● Clustered mode server.● Auto-pruning of subscribers.

23

● Always available (dial tone), fire and forget.● Never assumes the audience.● Distributed queueing across clusters, cluster aware clients.● Slow clients are being cut off.● Clients implement retry logic.● Extremely low latency!


NATS Latency - basically zero!

An example vs RabbitMQ
