AWS IoT Workflow

From Some more on AWS IoT. It’s a little difficult to simplify what’s going on, but I think this is pretty good. At the highest level, think of it this way: AWS IoT recieves messages and routes them based on rules to other AWS services

Here’s the basic workflow of AWS IoT. It’s a simplification and leaves out a number of important services, but this is the core of it. Understanding this is to understand what AWS IOT can do … and what it can do for you.

Here’s the workflow:

• your Things send messages
• the Device Gateway receives and authenticates the messages
• the Rules Engine authorizes the messages and then routes them to other AWS services

Weave Net and Docker Swarm

This example show how-to setup a very simple Swarm cluster enabled with Weave Net.

## Infratructure

There are two hosts that have a recent version of Docker Engine running.

These hosts are named host1 and host2, and might have the following in /etc/hosts or you just substitute IP addresses in the commands shown below.

- What do Etcd, Consul, and Zookeeper do?
  - Service Registration:
    - Host, port number, and sometimes authentication credentials, protocols, versions
      numbers, and/or environment details.
  - Service Discovery:
    - Ability for client application to query the central registry to learn of service location.
  - Consistent and durable general-purpose K/V store across distributed system.
    - Some solutions support this better than others.
    - Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state.
    - Centralized locking can be based on this K/V store.
