What is IoT?
“In the broadest sense, the term IoT encompasses
everything connected to the internet, but it is
increasingly being used to define objects that "talk" to
each other.”
"Simply, the Internet of Things is made up of devices
– from simple sensors to smartphones and wearables
– connected together"

What is DevOps?

11. DevOps in an IoT World – Copyright Pete Gallagher 2020 – @Pete_Codes
What is DevOps?
“DevOps is a set of practices that combines
software development (Dev) and information-
technology operations (Ops).
It aims to shorten the systems development life
cycle and provide continuous delivery with high
software quality”
https://en.wikipedia.org/wiki/DevOps

12. DevOps in an IoT World – Copyright Pete Gallagher 2020 – @Pete_Codes
What is DevOps?
“To practice DevOps effectively, software
applications have to meet a set of architecturally
significant requirements (ASRs).
Such as: deployability, modifiability, testability,
and monitorability”
https://en.wikipedia.org/wiki/DevOps

What is Docker?
“Docker is a set of platform as a service (PaaS)
products that use OS-level virtualization to deliver
software in packages called containers”
“Containers are isolated from one another and
bundle their own software, libraries and
configuration files; they can communicate with each
other through well-defined channels”
https://en.wikipedia.org/wiki/Docker_(software)

28. DevOps in an IoT World – Copyright Pete Gallagher 2020 – @Pete_Codes
What is Docker Hub?
“Docker Hub is a service provided by Docker for
finding and sharing container images with your
team.”
“Docker Hub provides the following major
features: Repos, Teams & Orgs, Official Images,
Publisher Images, Builds, Webhooks”
