My talk from DevOpsCon Berlin 2016.
Ansible is a radically simple and lightweight provisioning framework which makes your servers and applications easier to provision and deploy. By orchestrating your application deployments you gain benefits such as documentation as code, testability, continuous integration, version control, refactoring, automation and autonomy of your deployment routines, server and application configuration. Ansible uses a language that approaches plain English, uses SSH and has no agents to install on remote systems. It is the simplest way to automate and orchestrate application deployment, configuration management and continuous delivery.
In this tutorial you will be given an introduction to Ansible and learn how to provision Linux servers with a web-proxy, a database and some other packages. Furthermore we will automate zero downtime deployment of a Java application to a load balanced environment.
Reliable and scalable applications need repeatable, automated application deployment. Configuration management tools like Chef, Puppet and others make it easy to deploy an entire application stack, but support for Perl applications has lagged behind other popular, dynamic languages.
The Perl community has responded to these challenges with tools like perlbrew, local::lib, carton and others to make it easier to manage an application and its dependencies in isolation. This presentation will show you how to make those tools work with Chef for complete automation of Perl application deployment.

Cooking Perl with Chef: Real World Tutorial with JitterbugDavid Golden
This tutorial provides a command-by-command walk-through for deploying the Jitterbug continuous integration application using the Chef configuration management tool
The guide helps you understand how Chef works. It will also demonstrate about the primary usage and getting started with installing Chef-Solo over your workstations.
However, it will also help you to figure out how to configure Chef Server, Knife and Chef-Client at your stack making it possible to let them all communicate together.
Lessons from Etsy: Avoiding Kitchen Nightmares - #ChefConf 2012Patrick McDonnell
Talk by Patrick McDonnell (@mcdonnps) at #ChefConf 2012
Chef makes it so easy to change configuration en masse that it can be dangerous if not used with certain precautions and in accordance with a well thought out testing workflow. In our use of Chef at Etsy, we have devised many in-house best practices in response to failures which have helped greatly in avoiding catastrophic outages. This talk will focus on mistakes we've made and how we've avoided repeating them by enforcing standards in cookbooks, testing changes before rollout through the use of environments and in conjunction with the Spork plugin for Knife, and linting cookbooks with Foodcritic. I'll also talk about using handlers intelligently to monitor Chef runs and how to generate reports from the myriad data available in CouchDB.
Habitat-managed Chef with Policyfiles: Learn how to leverage the power of Habitat, chef-client and Policyfiles to produce an immutable application containing all of your chef cookbooks that can be locally tested and provides a consistent and guaranteed picture of desired configuration state across all target environments.
This talk is an in-depth look at all we, at Chef, have learned and what we love and what could be better about Configuration Management, Continuous Delivery and DevOps. We'll explore the pain points that still exist, especially as teams try to bring containers and microservices into production. We’ll then explore how to ensure the apps you build, deploy, and manage behave consistently in any runtime — metal, VMs, containers, and PaaS. You'll spend less time on the environment and more time building features.

Launch Your Streaming Platforms in MinutesRoshan Dwivedi
The claim of launching a streaming platform in minutes might be a bit of an exaggeration, but there are services that can significantly streamline the process. Here's a breakdown:
Pros of Speedy Streaming Platform Launch Services:
No coding required: These services often use drag-and-drop interfaces or pre-built templates, eliminating the need for programming knowledge.
Faster setup: Compared to building from scratch, these platforms can get you up and running much quicker.
All-in-one solutions: Many services offer features like content management systems (CMS), video players, and monetization tools, reducing the need for multiple integrations.
Things to Consider:
Limited customization: These platforms may offer less flexibility in design and functionality compared to custom-built solutions.
Scalability: As your audience grows, you might need to upgrade to a more robust platform or encounter limitations with the "quick launch" option.
Features: Carefully evaluate which features are included and if they meet your specific needs (e.g., live streaming, subscription options).
Examples of Services for Launching Streaming Platforms:
Muvi [muvi com]
Uscreen [usencreen tv]
Alternatives to Consider:
Existing Streaming platforms: Platforms like YouTube or Twitch might be suitable for basic streaming needs, though monetization options might be limited.
Custom Development: While more time-consuming, custom development offers the most control and flexibility for your platform.
Overall, launching a streaming platform in minutes might not be entirely realistic, but these services can significantly speed up the process compared to building from scratch. Carefully consider your needs and budget when choosing the best option for you.

Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.

2. After completing this module, you should be able to use
chef-client to:
Locally apply a cookbook's recipe with chef-client.
Locally apply multiple cookbooks' recipes with chef-
client.
Include a recipe from within another recipe.
Objectives
Slide 2 of 32
3. chef-apply is a great tool for applying resources (-e)
and for individual recipes but it doesn't know how to
apply a cookbook.
chef-apply
https://docs.chef.io/ctl_chef_apply.html
Slide 3 of 32
4. chef-client is an agent that runs locally on every node
that is under management by Chef.
When a chef-client is run, it will perform all of the
steps that are required to bring the node into the
expected state.
chef-client
https://docs.chef.io/chef_client.html
Slide 4 of 32
5. chef-client's default mode attempts to contact a Chef
Server and ask it for the recipes to run for the given
node.
We are overriding that behavior to have it work in a
local mode.
--local-mode
Slide 5 of 32
6. In local mode, we need to provide a list of recipes to
apply to the system. This is called a run list. A run list
is an ordered collection of recipes to execute.
Each recipe in the run list must be addressed with the
format recipe[cookbook-name::recipe-name].
-r "recipe[cookbook-name::recipe-name]"
Slide 6 of 32
7. When you are referencing the default recipe within a
cookbook you may optionally specify only the name of
the cookbook.
chef-client understands that you mean to apply the
default recipe from within that cookbook.
-r "recipe[cookbook-name(::default)]"
Slide 7 of 32
8. Example Usage
Using chef-client to locally apply the setup recipe from the workstation
cookbook.
$sudochef-client--local-mode–r"recipe[workstation::setup]"
