Deploying Keycloak to AWS using a Ubuntu AMI

Deploying Keycloak to AWS

The objective of this guide is to deploy Keycloak to AWS in a minimally complex way for testing and discovery purposes. This means using the standalone build of Keycloak backed with Hibernate H2. The result is not a production ready system. It won't scale, it won't survive significant load, it can't be clustered.

Mostly this Gist is a distillation of the Keycloak Server Installation guide for a specific use case: to spin up a quick and dirty Keycloak instance for testing and experimenting.

Steps

  • Spin up and configure a Ubuntu AMI
  • Install and configure Keycloak with an SSL cert

TPM2 Protocol Description

TPM2 Protocol Implementation

Introduction

Frame data is transferred inside packets (similar to DMX, for example). A frame is an image representing a matrix or a light scene.

The packets start and end with one-byte characters. In between are a few control bytes followed by the payload. There is no set size for a payload; it is transmitted with each packet. This makes the protocol quite flexible. There are enough bytes in a single packet for an RGB matrix with 21,845 pixels, but if you just want to control an RGBW lamp, that only requires 9 bytes. The variable frame size means there is no overhead, allowing for maximum transfer speed.
