Open Source PaaS: Deploy and Manage Applications on your own Servers

Deis is an open source PaaS based on Docker that runs on public cloud, private cloud and bare metal.
Deis allows software teams to deploy and scale almost any application on their own PaaS using a workflow inspired by Heroku. Deis combines Docker’s Linux container engine with infrastructure automation by Chef to create an application platform designed for developers and operations engineer

SALT: Infrastructure automation and management system

Salt, a new approach to infrastructure management, is easy enough to get running in minutes, scalable enough to manage tens of thousands of servers, and fast enough to communicate with those servers inseconds.

Salt delivers a dynamic communication bus for infrastructures that can be used for orchestration, remote execution, configuration management and much more

Packer – Create VM Images Quicker and Easier

Packer is a tool for creating identical images for multiple platforms from a single source configuration.

Packer supports multiple providers including Rackspace, AWS, Digital Ocean, VMWARE, Virtual Box and others.  Let’s look at how we can use Packer to make images on Rackspace.

First step is to download packer on to your Windows or Linux system

Packer uses JSON templates to define an image. Packer takes this JSON and runs the builds defined, producing a machine image.

To provison a Ubuntu 64bit VM on Virtualbox.  The JSON file will look similar to

“variables”: {
“ssh_name”: “trevor”,
“ssh_pass”: “trevor123″,
“hostname”: “packertest”
“builders”: [{
“type”: “virtualbox-iso”,
“guest_os_type”: “Ubuntu_64″,
“vboxmanage”: [
[“modifyvm”, “{{.Name}}”, “–vram”, “32”]
“disk_size” : 10000,
“iso_url”: “./ubuntu-14.04.1-server-amd64.iso”,
“iso_checksum”: “2cbe868812a871242cdcdd8f2fd6feb9″,
“iso_checksum_type”: “none”,
“http_directory” : “ubuntu_64″,

BRIDGE.NET - Run C# Code on Any Device

BRIDGE.NET is a platform which integrates with Visual Studio.NET and allows you to write your code in C# and then compile to Javascript

This enables you to run that C# code on any device which supports Javascript.

Check out BRIDGE.NET at

C# Code
using Bridge;using Bridge.Html5;namespace DemoApp {publicclassApp{[Ready]publicstaticvoidMain(){ Window.Alert("Hello World");}}}
Javascript Code Generated

Bridge.Class.define('DemoApp.App',{ statics:{ $config:{ init:function(){ Bridge.ready(this.main);}}, main:function(){ window.alert("Hello World");}}});

CRATE.IO : The Distributed Database Cluster for Developers

CRATE.IO enables developers to quickly set up a distributed database cluster, either on their own hardware or in a public cloud e.g. AWS.

One of the key advantages of CRATE.IO is its ability to scale.

The guiding principle for CRATE.IO is simplicity. Not only is it easy to set up, but once everything is up and running, developers can use standard SQL queries to work with their data.

To install crate  (CENTOS)

bash -c "$(curl -L"

You can connect to your twitter account and download tweets from your account and import in to a test table.
From here you can select the console from the web interface and run SQL standard queries against that table.

Run query against the tweets table imported
