Want to jump straight to the NATS hands-on?
NATS: A CNCF Incubating Project
NATS is a cloud native Computing Foundation (or CNCF incubating project). An incubating project is the middle of three tiers (sandbox, incubating and graduated).
Incubating projects have a an established security protocol, commits or contributions from a variety of people and not just one person, project or company. All of that means that NATS (or incubating projects in general) should have a fairly stable life and should not just dissapear overnight - meaning they should be safe to adopt.
What is NATS?
NATS describes itself as message oriented middleware. Two computer systems (A & B) need to send data to one another.
Nat sits in the middle and enables that communication it does so based on subjects.
A “publisher” will publish a message to a particular subject and then one or more systems can listen to that subject and receive all data destined for them.
NATS Hands On
During the NATS hands-on exercise, NATS will be installed on a Kubernetes cluster.
You will then publish a message to a
test subject and another consumer will listen for messages on that
test subject. You will then create two new subjects:
names.cat and publish a
names.dog to show that none of the other consumers receive that message there’s only one person receiving that message.
New Project Each Week
Each week in 2023 I will pick a new open source project to review. The entire list is here.
The series is designed to be interactive - if you have a project you’d like me to review - please do get in contact and suggest a project!
I hope you enjoy the NATS project!
