This document discusses using Jenkins, jclouds, and CloudStack together to provide scalable continuous integration testing. It describes how the author transitioned from using dedicated Jenkins masters and VMs to dynamically provisioning build slaves from CloudStack on demand using jclouds. The key steps were building standard images with Packer, configuring the jclouds plugin in Jenkins to integrate with CloudStack as the cloud provider, and configuring jobs to spin up slaves when needed and terminate them after 30 minutes of idle time. This approach provides scalable testing resources that match the varying demand of their many projects.

Docker and Puppet for Continuous IntegrationGiacomo Vacca
Today developers want to change the code, build and deploy often, even several times per day.
New versions of software may need to be tested on different distributions, and with different configurations.
Achieving this with Virtual Machines it’s possible, but it’s very resource and time consuming. Docker provides an incredibly good solution for this, in particular if combined with Continuous Integration tools like Jenkins and Configuration Management tools like Puppet.
This presentation focuses on the opportunities to configure automatically Docker images, use Docker containers as disposable workers during your tests, and even running your Continuous Integration system inside Docker.
Node.js is a compelling platform that is quickly spreading from startups to the enterprise. As a .NET developer, why should you learn Node.js and where do you start? You will come away from this talk with the evidence and tools you need to be a productive Node.js developer. We'll walk through creating, debugging, and deploying a Node.js project to Microsoft Azure using the Node.js Tools for Visual Studio. We'll also look at popular frameworks and modules, and other learning resources.
Use Docker to Deliver Cognitive Services Running Cross Platform and Multi Clo...Docker, Inc.
Watson developer cloud delivers Watson Cognitive services as micro services on the cloud that are being used by many IBM Watson customers. The micro services were packaged in ova at the first release. There were some drawbacks in ova deployment in the cloud. We gradually switched to use docker. As a result, the service deployment time and start up time are significantly improved. It also greatly simplified our continuous delivery process since our services run on both Intel and Power platform and we have offerings on our public cloud, dedicated cloud as well as customers’ on premise cloud. With minimal deployment time and quick startup time, Docker makes our dynamic creation of service instance on the fly per customer request possible.

Creating Resilient, Dockerbased Applications using LatticeDustin Ruehle
When trying to install and get “hands on” with innovative technology, you may encounter frustrating barriers. It may seem daunting to install Cloud Foundry – especially when trying understand what to do after installation. Cloud Foundry’s Lattice simplifies this ops task. It allows you to get a sense of what Cloud Foundry does without having a "whole data center." Lattice also allows you to deploy apps in a Docker container. But then how do you create a Docker container that does something useful? This discussion will address installing Lattice using Terraform and will address the common Cloud Foundry operational concern of customizing a buildpack. To highlight a key feature of the new 3.0 Java Buildpack, we will use Cloud Rocker to build a Docker image with a customized Java Buildpack. The image will then be deployed to the new Lattice installation where some common ops tasks, such as scale up and scale down, will be demonstrated.
SQL Server is container-ready. This deck covers some of the common ideas, misconceptions, myths, and realities of databases like SQL Server in a DevOps model.
Configuring and maintaining a continuous integration environment is quite a bit of work. It requires ongoing resources both in terms of manpower and hardware infrastructure. As an application evolves so does the number of ongoing projects. The challenge is creating a scalable continuous integration environment which does not impede development and can handle the complexities of Java EE testing. This session covers how to setup and configure a cloud-based continuous integration environment for Java EE applications.
The presentation will focus on demonstrating how to use Atlassian Bamboo running on AWS to build and test a Maven/Gradle Java EE project that uses Arquillian for testing. Topics that will be covered include creating a custom AWS VM for use with Bamboo, creating an Amazon VPC (Virtual Private Cloud) along with test database using Amazon RDS. The presentation will delve into the specifics of testing EJBs, WebSocket endpoints, RESTful web services, as well as performing load testing in this environment. Security, cost control, and build monitoring will be covered as well.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

6. The Problem
Lots of different testing needs – multiple
platforms, multiple versions, multiple
versions of software.
Jenkins + jclouds + Centos + CloudStack
7. The Problem – at scale
We have nearly 200 software projects each with
their own set of needs, distinct platforms.
Some want CentOS 5, 6, or 7; others want OSX, Win
2012, Ubuntu, FreeBSD, or Solaris.
Demand varies widely – projects getting closer to
release test more; some days we had hundreds of
jobs in the queue, other days we had 20 or 30
Jenkins + jclouds + Centos + CloudStack
8. The transition for monolith to scalable.
Jenkins + jclouds + Centos + CloudStack
9. Where we were
Dedicated Jenkins master
Esoteric things had VMs
~30 dedicated machines, strewn across
multiple datacenters.
Jenkins + jclouds + Centos + CloudStack
10. How we started our move
• Defining what a build slave needs
• Make sure that Jenkins is working
efficiently
(Misconfigured jobs are a huge drain)
• Adopted a LTS version of Jenkins
Jenkins + jclouds + Centos + CloudStack
11. Building images
Packer – building images
Start with JeOS – declare everything else in
puppet, run puppet as a job.
Create a jenkins job for this – everytime a
job changes – rebuild, reupload.
Jenkins + jclouds + Centos + CloudStack
12. How you plan to use Cloud
Server huggers wanted to use fixed VMs
(deploy fixed machines)
Jenkins + jclouds + Centos + CloudStack
13. How you want to use cloud
Fresh, dynamically provisioned VM for each
build
Jenkins + jclouds + Centos + CloudStack
15. The right answer
(for us)
Spin up build slaves in response to demand.
Leave the machine up for 30 minutes after
demand subsides to keep from flapping.
Jenkins + jclouds + Centos + CloudStack
16. Make it all work

Editor's Notes
Do you know what continuous integration is?
CI is the practice, in software engineering, of merging all developer working copies with a shared mainline several times a day.
So Jenkins is merely a testing tool for use in CI.
CloudStack maintains its own CI server
The ASF has a top-20 in the world, Jenkins instance.
Originally written by Adrian Cole – now a top level project at the ASF
Java cloud bindings regardless of what your underlying cloud actually is

So Jenkins is merely a testing tool for use in CI.
And that’s just CloudStack
And that’s just CloudStack
We started this with Ansible – and for many of our build slaves still is the default.
The rest of our infrastructure is Puppet – so much of this is moving.
Developers – committers on Jenkins as a matter of fact – had us running bleeding edge, unreleased, with custom patches.
The first struggle I faced was explaining how IP addresses were dynamic, and that they couldn’t really reserve a block of them.
A perfectly clean workspace – nothing muddled – and perfect isolation – only a single job running at a time.
Downside is that spin up time can be excessive. Depending on the cloud provider you might have several minutes waiting – for the ASF – we discovered that using our own custom images made spin up much slower – a problem our public cloud vendor since solved.
Don’t do what we did and install a personal snapshot.
That said – a number of folks have been discussing creating provider-specific plugins.
