In this video, we look into installing Placement and Nova services. The Placement service is used to gather statistics about your cluster and figure out where to put instances. Nova is the controller and compute nodes that will do the actual work.
I took a look at the service provider interface in java. This is a needed interface to build simple services using easy building blocks to extend and improve programs or libraries. We will create one example and also look into some tools that use this interface already.
We are in our new linux environment and create gettext and OpenSSL, talking about internationallization and website security.
In this tutorial, I go through how to create a video in java. Using the framework Xuggle we can create a video file containing a stream of images. But you can use any BufferedImage to create these frames, so this library is super flexible and even support audio.
In this video, we look into Ceph erasure coding. This is a feature where you can use more of the available space in your cluster without losing too much redundancy. It’s more complex and gives you the option to have more or less safety.
We look into how to set up a good Crush Map and handle the placement and device types of your OSDs in your clusters. The crush map describes where, what type, how much and what is your failure domain or safety requirements. One thing we will do a lot throughout this demonstration is to view…
I’m trying to solve all the Advent of Code puzzles in this video series.
