OpenStack has been selected to be a mentoring organization for Google Summer of Code 2014. Thanks to the hard work of many contributors we could join GSoC for the first time. For those who haven’ t heard about it, GSoC is a full-time internship supported by Google that offers students worldwide a stipend to start contributing with coding tasks to an open source organization. This is a great experience for both parts, as it generates a flow of new people with fresh ideas in the organization and allows students to learn and taste how is to work on a real world software development environment.

Apigee: Big Data Predictive Analytics in Action: Healthcare/Medicare
For healthcare payers, the Affordable Care Act can be a double-edged sword. The law, which was enacted to improve health care affordability and quality, enforces more stringent reporting rules that require payers (insurers) to monitor quality of care, performance metrics, and member satisfaction. But high performance and quality can earn healthcare payers a coveted five-star rating on their Medicare Advantage products. Not surprisingly, there’ s a big incentive to improve this rating, and maintain a high one. Predictive analytics can play a very important role in this. Read more.
Chef: DevOps for developers w/Chef. Part II – DevOps in a nutshell
DevOps is a modern way of developing software by aligning the goals, processes and tools of development and operations with one another., see “ DevOps for Developers” , 2012. Core facets of DevOps include measurement, metrics and monitoring, improving the flow of features in a holistic approach as well as improving and accelerating delivery, e.g. with automation to gain fast feedback. Automation is important! But simplify your process first prior to automation. This helps to reduce variations in the process. Variations impede successful automation. Read more.

CERN: Our Cloud in Havana
At CERN, we started our production cloud service on Grizzly in July 2013. The previous OpenStack clouds had been pre-production environments with a fixed lifetime (i.e. they were available for use with an end date to be announced where the users would move to the new version via re-creating instances with tools such as Puppet or snapshot/upload instances). With the Grizzly release, we made the service available with an agreement to upgrade in place rather than build anew. This blog details our experiences. Read more.

eNovance: Use the new asyncio module and Trollius in OpenStack
Asynchronous programming is hard. In the past, the Nova project used Tornado, then Twisted and it is now using eventlet which also became the defacto standard in OpenStack. Eventlet is not perfect, we will explain why we consider that eventlet has major flaws. We will then introduce the asyncio module of Python 3.4, how we plan to use it in OpenStack, to finish with the current status of this integration. Read more.
eNovance: Status of the OpenStack port to Python 3
Python 3 has been around for about 5 years, and we have excellent reasons to make sure OpenStack runs well on it. Unfortunately, this is not the case. In this article, we’ll see what works, what doesn’t, and what you can do to help. Note that we are targetting the latest released version, Python 3.3. Read more.
Inktank: Multisite Storage with Inktank Ceph Enterprise
Support for multi-site operations is one of the most sought after Ceph features. If you’re an enterprise, you may want to store your data in multiple locations to ensure business continuity in the case of a regional outage. If you’re a service provider deploying a public object storage service, multiple sites can help provide the lowest possible latency to your users. We recommend a few different approaches for multi-site operation with Inktank Ceph Enterprise, each with their own characteristics and applicable use cases. This document discusses these options and explains the use cases they serve best. Read more.
Jamie Lennox: Client Session Objects
Keystoneclient has recently introduced a Session object. The concept was discussed and generally accepted at the Hong Kong Summit that keystoneclient as the root of authentication (and arguably security) should be responsible for transport (HTTP) and authentication across all the clients. The majority of the functionality in this post is written and up for review but has not yet been committed. I write this in an attempt to show the direction of clients as there is currently a lot of talk around projects such as the OpenStack-SDK. Read more.

Rackspace: Software Defined Networks in the Havana Release of OpenStack
Software Defined Networks (SDN) are a key technology in enabling users of cloud environments to build a wide variety of virtual environments. The OpenStack network project, Neutron, has been growing at a rapid pace to the point that the OpenStack user can build virtual machines (VM) into various flexible network implementations. This can present a challenge to OpenStack administrators who may not have a clear understanding of the technologies that OpenStack uses to create these virtual networks. This is the first in a series of articles that will look closely how OpenStack Neutron implements these virtual networks. Through the course of these articles we will look in detail how virtual networks are created in Neutron, how data in different networks in kept separate and security features built into the security group functionality. Read more.
Rackspace: Software Defined Networks in the Havana Release of Openstack – Part 2
In the first article in this series we looked at a simple OpenStack setup with one controller node, one compute node and one network node. Two tenants had been created with two simple networks. In this article we will turn our attention to the network paths for each of the three VMs that were created. The diagrams in the first article will be useful in understanding this discussion.

The goal of Cloud Foundry is to create portability across Infrastructure-as-a-Service (IaaS) technologies, including OpenStack, AWS and Vmware. Read more.
Rackspace: Taking OpenStack For A Spin: Using The Rackspace Private Cloud Sandbox
Late last year, we released Rackspace Private Cloud (RPC) 4.2.1, which is based on the Havana release of the OpenStack cloud platform. Along with this RPC release, Rackspace also made available version 1.0 of the Rackspace Private Cloud Sandbox, a virtual appliance that runs an all-in-one single node RPC VM that allows anyone to quickly spin up a small OpenStack environment for test and demonstration purposes. This virtual appliance is distributed as an OVA package and can be imported and used in Oracle VM VirtualBox, VMware Fusion, VMware Player or VMware Workstation. The Sandbox was a direct result of your feedback. You said you wanted to be able to experiment with RPC or to demonstrate the OpenStack Horizon dashboard to colleagues or managers; however, you did not want to have to spend time installing a Chef server and running through a full RPC install for these tasks. So in response, the RPC Product team created the RPC Sandbox so you can get a small OpenStack-based cloud environment up and running in minutes on your laptop or workstation. Read more.
