This document discusses different architectures for connecting smart devices like light bulbs to smartphones and the internet, including smartphone-centric, hub-centric, and cloud-centric architectures. It also discusses the competition between Google, Apple, and Amazon to establish their own ecosystems and platforms to organize connected home devices and lock customers into their gardens through services tied to devices like OnHub, Apple TV, Amazon Echo, and smart home devices that integrate with their platforms and APIs.

2. How Cloud IOT works

10. 1. Smartphone Centric Architecture (with or without cloud)
In smartphone-centric architecture a light bulb is connected directly to a smartphone via Bluetooth. Thus
the light bulb doesn’t have a direct link to the Internet and depends on the proximity of the smartphone.

11. 2. Hub-centric Architecture (with or without cloud)
The Hub in hub-centric architecture is working as an intermediary for
connecting a bulb to the smartphone and to the Internet, since it usually
connects to the home Wi-Fi or Ethernet network. A smart lightbulb is totally
independent of a smartphone and could be smart on it’s own.

12. 3.Cloud Centric Architecture (without hub)
We have a smart device that is directly connected to the home Wi-Fi network
and doesn’t need any additional hub to work.

13. Smart Home Ecosystem Wars:
Android Brillo + Weave vs HomeKit
vs Amazon Echo
There is a constant battle of ecosystem platforms designed to organize and connect our
home appliances. Such a platform is a necessary and required step before we can
invent and build more services on top of the connected smart home devices.
Google and Apple are moving towards the Hub centric architecture with OnHub and
Apple TV respectively. They both also have their own infrastructure ecosystems (Brillo +
Weave from Google and HomeKit from Apple) that are aiming to keep customers
locked within their walled gardens. Such an approach will allow Google and Apple to
have full control over your home, know everything about you and your family and
provide added services to you for an additional cost. This will be a good scenario with a
recurring business model for them.

14. Amazon is also trying to build the
same ecosystem with Amazon Echo
and a fleet of third party connected
hardware appliance. Eventually the
result will be the same locked
ecosystem for the consumer in which
she can use content and services and
buy her household products from
Amazon. Another great concept from
Amazon, which is currently tested
only with its Prime Members, is the
Amazon Dash buttons that allow
users to buy products with literally
one click of a button that is attached
to a wall in the kitchen or bathroom.

15. Amazon released the Lightning API
for the Amazon Echo, which lets
customers control lights and switches
by speaking a command. If you are a
smart light bulb developer you can
benefit from such integration, which
increases interoperability and gives a
customer more options when using
the device.
