Using OpenStack With Fog

This document provides an overview of Node.js, including what it is, its key features, and how to test a Node.js installation. Node.js is a JavaScript runtime environment that allows building scalable network applications in a single programming language. It uses non-blocking I/O and event-driven architecture, making it suitable for data-intensive real-time applications. The document demonstrates creating an HTTP server in Node.js, using the built-in URL module, and shows how Node.js uses an asynchronous and event-driven platform. It concludes by providing a link to a demo login application built with Node.js on GitHub.

WSGI is a specification for connecting HTTP servers to web applications through a common interface. It defines an application as a callable object that receives environment variables from the server and returns a response. WSGI also supports middleware as callable objects that can process requests and responses between the server and application.

This document discusses integrating OpenStack with Active Directory at Go Daddy. It covers configuring Keystone and Nova to authenticate against Active Directory using LDAP. It also discusses integrating DNS and deploying the integration using Puppet.

This document provides an overview and instructions for installing and using Elasticsearch. It describes how Elasticsearch is schema-free, distributed, uses JSON documents and the Lucene search engine. It also provides examples of indexing, searching, and configuring documents in Elasticsearch including shards, replicas, node names and master/data nodes.

More mobile technologies are empowering people and machines to become more autonomous. In the same way as people, machines need ways to be identified to other sources in a connected environment. This begs the question, why not give a URL to objects? With Eddystone, a new Google specification for Beacon data, this is possible, and it works with both Android and iOS based devices. With it you can implement what physical-web.org stands

This document provides an overview of the Web Server Gateway Interface (WSGI) specification and its components. WSGI defines the interface between web servers and web applications to allow them to evolve independently. It outlines the operations and responses expected between servers and applications. WSGI allows for easy integration of middleware components into applications and servers. Common Python web servers, frameworks, and middleware examples are also described to demonstrate how WSGI enables components to work together.

This document discusses OpenStack deployments using Puppet and provides an overview of OpenStack components and architecture. It describes how Puppet modules correspond to OpenStack projects and can be used to build and manage OpenStack deployments. It includes examples of Puppet profiles and classes to configure common OpenStack services like Keystone, RabbitMQ, MySQL, and Nova.

Building a "recommended books" application on Google App Engine for Java "early look", using Groovy to help out on the XML processing.

OpenStack Glance provides image discovery, registration, and retrieval services. It has a RESTful API and supports storing images on various backends like filesystems and OpenStack Swift. Glance components include the Glance API, registry, and database. It supports many disk and container formats and has a caching mechanism. Images can be managed through the Glance API and used to launch instances.

The document discusses scaling the Mapufacture web service using Amazon Web Services (AWS). It covers using EC2, S3, and SQS services on AWS. It provides examples of running instances on EC2, storing files on S3, and using SQS queues. It also discusses database sharding, replication, and costs associated with AWS services.

Mini tech-talk to introduce ElasticSearch to developers and present benefits and trade-offs of the solution.

Imagine proposing a session on “What’s new in Notepad”! Why would anyone want to know about such a common tool that everyone knows? The same should could be said about docker and docker-compose. They are standard development tools we find in any dev shop. So why does docker-compose seem so elusive? Its simple: - Compose is a tool for defining and running multi-container Docker applications. - With Compose, you use a YAML file to configure your application’s services. - Then, with a single command, you create and start all the services from your configuration. Join me as we demo using Compose via your favourite frameworks.

This document discusses distributed eventing in OSGi frameworks. It describes how OSGi event admin works, including publishers, subscribers, and immediate delivery of events. It then discusses the need for distributed eventing as specified in RFP 158. It explains how Apache Sling implements distributed eventing by leveraging OSGi event admin and distributing events through its content repository. It also describes Apache Sling's topology model for discovery of instances, clusters, and properties. Finally, it discusses how event-driven architectures can be extended to support guaranteed job processing using a job handling approach.

This document discusses debugging and testing Elasticsearch systems. It provides tips for debugging issues like typos in mappings, setting up a local environment for testing, useful commands like analyze and explain, tuning queries, and testing strategies using Java and Ruby. The document emphasizes the importance of testing representative queries to ensure expected results and the ability to tune queries without breaking other queries. It also recommends using Elasticsearch plugins like Head for visualizing clusters and indices.

This document discusses using AWS IoT for home IoT projects. It introduces the author and their motivation to try AWS IoT after their child was born. It provides an overview of AWS IoT components like Device Gateway and Rule Engine. It then describes three demo projects - the first collects humidity sensor data using MQTT, the second controls an LED using Device Shadow, and the third integrates humidity sensing, LED control, and a Lambda function to analyze sensor data and update the Device Shadow.

This document provides an overview and introduction to using the libcloud library for multi-cloud management. It discusses key concepts like providers, drivers, images, sizes and locations. It provides examples of how to connect to providers like EC2 and Rackspace, launch nodes, list existing nodes, and destroy nodes. Libcloud supports a common API across many cloud providers for tasks like compute management.

my presentation at houston.rb on Grape, the API builder for rack based systems using a friendly ruby/sinatra like interface. It makes separating out your API from you web app logic really easy.

Clonezilla es un software libre que permite clonar particiones y discos duros de forma rápida y sencilla. Ofrece soporte para sistemas Linux, Windows y Mac a través de una interfaz gráfica intuitiva. El documento explica cómo usar Clonezilla para crear una imagen de respaldo de una partición y luego restaurarla en caso de que se produzcan cambios no deseados, lo que permite recuperar fácilmente el sistema operativo original.

Slides from Docker Austin Meetup on 2016-08-04 with an overview of OpenStack Magnum, how we use it in Carina on private clouds, an overview of the Container Orchestration Engines Magnum supports, and an overview of how to manage your COEs with Magnum (v1). Includes a link to a video demo.

This document discusses container technology and its integration with OpenStack. It provides an overview of how containerization has evolved over time through various independent projects. It describes how several OpenStack projects like Nova, Heat, Kolla, Murano leverage containers. It focuses on how Magnum provides APIs for container orchestration engines and how Kuryr connects Docker and Kubernetes networks to OpenStack. It then introduces the Open Container Initiative (OCI) and Cloud Native Computing Foundation (CNCF), which aim to develop open standards for containers and cloud-native applications. The presenters encourage attendees to get involved in these standards bodies to help ensure the standards meet their usage scenarios.

Why do containers suddenly matter so much when they have been around since 1998? Take a look at the potential of OpenStack's Magnum, Murano and Nova-Docker in the context leveraging the incredible interest in Linux Containers brought about by Docker.
