Three keynotes were given at DrupalCon 2011 in Chicago by Dries Buytaert. Free and open source tools for integrating web accessibility into the design process were discussed, including Wave, Run Fae, and the Accessibility Inspector. A session on using HTML5 features with Drupal covered new input types, video, audio, and canvas elements. Webform 3, the survey module for Drupal, was presented along with its new API and features.
Traditionally at Bandai Namco Studios, there has been no unified version control system in place and teams could choose to use any VCS system for their game titles—Subversion, Git, AlienBrain, or none at all. I’ll talk about why Bandai Namco Studios chose to standardize on Perforce Helix, show how we develop LiveOps-type mobile applications using the Unity game engine, and the advantages we gain from centrally managing code and assets in Helix.
This document discusses trends related to databases and cloud computing. It notes that 85% of enterprises have a multi-cloud strategy and that workloads are increasingly being run in public and private clouds. It also discusses the growth of various cloud vendors and databases like PostgreSQL. The document emphasizes that organizations should optimize databases before migrating to the cloud in order to reduce costs related to things like data transfers and storage. It also stresses the importance of securing data during non-production usage by encrypting and masking sensitive information.
The document discusses opinionated containers and containerizing game server applications. Containerizing simple applications like TeamSpeak is straightforward, but complex games like Team Fortress 2 pose unique challenges due to requirements for specific configuration files, port mappings, and handling of persisted state. While containerizing opinionated applications is becoming more common, the game server ecosystem presents difficulties around proprietary assets, obscured documentation, and hacker behavior that promote inflexible environments. Standardizing configuration methods and allowing external persisted state could help containerized game servers become more compatible and deployable at scale.
From a webinar I did with Sonatype. In it I discuss the importance of a private registry to make sure Docker adoption is successful and sustainable in the Enterprise.
Hey curious friend, let's play a game. How can we bring together two different companies, an established enterprise with traditional dev and ops having cultural differences when working together with a DevOps champion startup. In the middle exists a number of real use cases on how we are bringing DevOps culture with Docker to Atos Worldline. In my talk I will discuss the first use cases for Docker at Atos Worldline, where we are today, learnings and benefits until now, our future technology stack and how Docker is changing our human stack a.k.a. how we communicate and work together.
Docker is the developer-friendly container technology that enables creation of your application stack: OS, JVM, app server, app, database and all your custom configuration. So you are a Java developer but how comfortable are you and your team taking Docker from development to production? Are you hearing developers say, “But it works on my machine!” when code breaks in production? And if you are, how many hours are then spent standing up an accurate test environment to research and fix the bug that caused the problem? This workshop/session explains how to package, deploy, and scale Java applications using Docker.
The document summarizes Alfresco's Software Provisioning Kit (SPK) which helps define, build, and integrate Alfresco stacks. SPK uses Chef to automate Alfresco installation and configuration. It provides reusable templates and stacks that can be run locally using Vagrant or built into immutable images using Packer. SPK aims to simplify Alfresco provisioning across cloud providers and orchestration tools through infrastructure as code.
Alfresco has gone a long way in providing best-of-breed tools to power the full spectrum of an ECM project, from inception to delivery. In this session, based on real business cases, we'll demostrate how, using tools like the Maven Alfresco SDK and Alfresco Boxes, you can deliver a fully working Alfresco customized project from scratch running in the Cloud, all of this using quality focused, reproducible, reliable, Enterprise ready processes.

Kubernetes can run application containers on clusters of physical or virtual machines. It can also do much more than that. Kubernetes satisfies a number of common needs of applications running in production, such as co-locating helper processes, mounting storage systems, distributing secrets, application health checking, replicating application instances, horizontal auto-scaling, load balancing, rolling updates, and resource monitoring. However, even though Kubernetes provides a lot of functionality, there are always new scenarios that would benefit from new features. Ad hoc orchestration that is acceptable initially often requires robust automation at scale. Application-specific workflows can be streamlined to accelerate developer velocity. This is why Kubernetes was also designed to serve as a platform for building an ecosystem of components and tools to make it easier to deploy, scale, and manage applications. The Kubernetes control plane is built upon the same APIs that are available to developers and users, implementing resilient control loops that continuously drive the current state towards the desired state. This design has enabled Apache Stratos and a number of other Platform as a Service and Continuous Integration and Deployment systems to build atop Kubernetes. This presentation introduces Kubernetes’s core primitives, shows how some of its better known features are built on them, and introduces some of the new capabilities that are being added.
The document discusses DevOps and how it relates to big data. It defines DevOps as combining tools and culture to enable automation, infrastructure as code, and collaboration between developers and system administrators. It promotes principles like idempotence, data-driven configuration, sane defaults, and hackability. The document argues that an API-driven approach with Chef can help implement DevOps practices for big data environments.
This presentation discusses two key components of our deployment pipeline: Continuous integration of Chef code and automated deployment of Java applications. CI jobs for Chef code run static analysis and then provision, configure and test EC2 instances. Release jobs publish new cookbook versions to the Chef server. Deployment jobs identify target EC2 and VMware nodes and orchestrate Chef client runs. The flexibility of Jenkins is essential to our overall delivery architecture.
Device configuration templates have simplified a lot of things for the network industry but many networks are still managing their device properties (aka variables) manually which is very tedious and error prone. This talk will present a new approach to generate and manage network device properties easily using infrastructure as code principles.

This document introduces using Jupyter Notebooks or .NET Interactive Books to create interactive troubleshooting guides and documentation for Kubernetes deployments. Notebooks allow including executable code blocks alongside Markdown text in a way that supports collaboration and version control. They provide benefits over traditional static documentation formats by allowing readers to execute code and see output. Examples are given of using Notebooks to manage local and Azure Kubernetes Service clusters through demonstrations of common Kubernetes tasks like plotting metrics from kubectl. PowerShell is used as the shell language but other options like bash are also supported.
Presented at the Chef NYC meetup on April 20, 2017, this presentation reviews how to automate compliance scanning and reporting with InSpec by Chef and wrapped up with a hands-on workshop.
I don't know any other languages with more pitfalls, perils and gotchas than Bash. Still, we use it in almost every larger project for deployment or maintenance scripts, because there is no better, more powerful and more universal choice on Unix platform. However, there is ridiculous amount of things that could go wrong if you don't have deep understanding of shell scripting. Your experience about typical issues with Java or other JVM languages is definitely not enough here. You need to deeply understand Linux ecosystem and its history in order to write correct script... or you don't? I will prove to you that Bash could be tamed and made easy if proper code quality standards and static analysis tools are applied and enforced in your delivery pipelines. I'll share my opinions and experiences from a large banking project and I'll tell you which tools and style guides we use.
Introduction to some of the newer, available tools for use in standardizing and managing server infrastructures. Also includes simple ways on
This document provides an introduction to PowerShell for database developers.
