Ever thought about what it takes to write a scalable cloud application using an OpenStack SDK? Thanks to a small team’s heroic effort, there’s now a guide for that!

Christian Berendt (B1 Systems), Sean Collins (Mirantis), James Dempsey (Catalyst IT) and Tom Fifield gathered in Taipei, with Nick Chase live via video link, to produce “Writing Your First OpenStack Application” in just five days. The sprint was organised by the Application Ecosystem Working Group, with the financial support of the OpenStack Foundation.

The new work is aimed at software developers who want to build applications on OpenStack clouds and also shares some best practices for cloud application development.

Inspired by Django’s first app tutorial, where a simple polling app is used to explore the basics of working with Django, “Writing Your First OpenStack Application” uses an app that generates beautiful fractal images as a teaching tool to run through areas like:

• Creating and destroying compute resources.
• Scaling available resources up and down.
• Using Object and Block storage for file and database persistence.
• Customizing networking for better performance and segregation.
• Making cloud-related architecture decisions such as turning functions into micro-services and modularizing them.

The guide has been written with a strong preference for the most common API calls, so it will work across a broad spectrum of OpenStack versions. In addition, the authors have paid special attention that the first few sections should work almost regardless of OpenStack cloud configuration.

A core part of the guide’s design is support for multiple SDKs. The initial version was written and tested with the libcloud SDK, but work is underway for python-openstacksdk, pkgcloud and fog which will re-use the text with new code samples.

So, check out “Writing your First OpenStack Application” for libcloud, watch the introductory presentation from the summit, or consider helping complete the samples for other languages.

Set your travel plans early if you plan to come to OpenStack’s 2015 Tokyo Summit, and even earlier if you need a visa

Tokyo visa application

The Visa application process for Japan will require more time than any of the previous Summits.

What does that mean? 

The 2015 OpenStack Summit to be held in Tokyo from Oct., 27-30 requires all applicants to have the following information BEFORE they apply for visa support invitation.

• Flight
• Hotel
• Summit Registration

Due to these requirements, we recommend summit attendees who need to apply for a visa to book fully REFUNDABLE flights and hotel accommodations. All invitation letters are written in Japanese and mailed via regular post from Japan to the traveler. This process takes three to five weeks. Also, once the visa is issued it’s only valid for three months – so for the summit, all of our visa requests have to be received between mid-July and October 1. There are about 70 countries who do NOT need to apply for a visa to visit Tokyo so please look over this list to confirm if your country is exempt or not. Additional visa information is now live on our website here: http://bit.ly/1CHwKiE.

Tokyo travel support program

For each OpenStack Summit, OpenStack assists its key community members with travel. If you are a contributor to OpenStack (developers, documentation writers, organizers of user groups around the world, Ask moderators, translators, PTLs, code reviewers etc.) you are invited to submit a request. Access the application and apply here: http://bit.ly/1C6a1SC

New OpenStack component versioning

Thierry Carrez explains why the Liberty-1 milestone release has some unfamiliar version numbers for familiar projects.

Technical Committee Highlights June 25, 2015

A compute starter kit tag has been approved, it provides a place for a beginner who only wants to try to get a computing cloud use case started. New projects under the OpenStack “Big Tent”: Searchlight, OS-ansible-deployment (OSAD), Solum and Cue Message Broker service.

Forrester says: ready, set, OpenStack!

A recent report from Forrester gives a major boost to OpenStack adoption, calling its “viability and presence in the market irrefutable.” You can download the entire report for a limited time on the OpenStack.org website.

Beginners, start your engines

A compute starter kit tag has been approved, it provides a place for a beginner who only wants to try to get a computing cloud use case started. We discussed some reservations about recommending such a simple starting point, including only using nova-network for inter-vm networks, and recommending multi-host for that use case, but feel the current tagged projects indicate a decent starting point for now. We’ll update it as we see improvements to the starting experience. The projects for an OpenStack starter kit are: cinder, glance, keystone, and nova. Additional tags are being proposed to help with the release mechanisms for a type:service tag, and type:library tag merged this week.

Welcome, new projects

We welcomed new projects to the “we are OpenStack” definition, including:

• Searchlight, providing indexes and search across cloud resources
• OS-ansible-deployment (OSAD), deploying OpenStack using Ansible playbooks
• Solum, managing the application lifecycle and source-to-image workflows
• Cue Message Broker service project proposal, for deploying and managing message brokers using a REST API

There were several topics we didn’t get to discuss in this meeting due to the longer discussion about the compute starter kit, but we will get to those next week. Check the meeting agenda on the wiki any time you wonder what topics are up for discussion.

Project Team Guide sprint

The sprint for the Project Team Guide was last week, and the authors are going great gangbusters. The goal for this guide is to provide teams a starting point for understanding our philosophy and general thinking about what it means to be an OpenStack project. See the review queue for the work in progress. It’s not published to the web yet, so if you’d like to write or revise anything, propose a patch for review to the project-team-guide repository and build it locally.

Awaiting the M name

The poll for the M release name closed this week and we’re all awaiting the final name selection. Stay tuned to the openstack-dev mailing list for the final M name.
