Tokyo Open Infra Users Group

The Tokyo Open Infra Users Group (TOIUG), formerly Wakame Users Group (WUG), is Axsh's official bilingual (English/Japanese) community. It's an informal group discussing all topics related to open source virtualization, infrastructure, devops, etc.

Do you have a question for us? Have you done a cool hack? Did a new technology come out that looks interesting? Do you just want to hang out? We would love to have you over.

Axsh hosts a Google Group, a Doorkeeper page and a public HipChat room to accomodate a forum where people can have discussions and related news can be announced.

Every three months TOIUG organizes a meet-up with some cool presentations by both Axsh employees and community members. After the presentations, everyone is invited to come hang out and have some beers.

Event Format

During TOIUG events, we foresee time for two presentations. Before every event a request for presentations is sent out to the community. Everyone, including people that never attended before, is free to send their request to present a topic of their own. We strongly encourage community presentations.

After every event a nomikai (Japanese drinking party) is organized for everyone to network and socialize.

If you're attending, registration on Doorkeeper would be appreciated but is not required.

Scheduled presentations

Overview of Axsh's newest project: OpenVDC

In Japanese by unakatsuo

OpenVDC's goal is to bring a strong infrastructure testing suite to the industry. The main motivation for the project is to build a device agnostic provisioning engine for datacenters.

We envision an infrastructure testing suite covering configuration and validation for physical network devices. While infrastructure testing code runs, those physical network devices have to be available but they don't have to be dedicated to specific tests. The OpenVDC project can dynamically provision physical network devices as well as virtual resources for infrastructure testing.

In this session, unakatsuo will talk about:

  1. Design goal
  2. Current architecture and progress
  3. Underlying technology (Mesos, Zookeeper, Golang)
  4. Q&A

Using Clay to combine OpenVDC and OpenVNet into an autotesting tool

In Japanese by Metallion


Clay is a project written in Go by qb0C80aE specialized in creating virtual networks for testing. For example if you have a physical router or firewall running in production, changing its settings can be a very scary thing to do. If any of the new settings break something on the production network, engineers need to scramble to fix it, users experience down time and the company loses money.

Clay allows you to create a virtual network and generate test cases though either a GUI or a Web API. Behind the scenes it will generate a Terraform template which will then build the virtual topology on top of OpenVDC and OpenVNet. Once that is done, Clay will execute automatically generated test cases on this virtual environment. This way any new network settings can be thoroughly tested before applying them in production.

This presentation will include a live demo.
