LinuxCon + CloudOpen Japan 2014

OpenStack, the fastest growing infrastructure-as-a-service (IaaS) platform in the open source community, has recently added a database-as-a-service (DBaaS) named Trove, scheduled for its first production OpenStack release in April. Trove's purpose is to provide scalable and reliable cloud DBaaS provisioning functionality for both relational and non-relational database engines. With OpenStack Trove, database administrators can quickly provision and scale database capacity in the cloud and manage multiple database management systems (DBMS) such as MySQL, MongoDB and others from a single, unified management tool.

The audience for this presentation are those people who want to know more about the new OpenStack Trove service. Trove's purpose is to provide scalable and reliable cloud DBaaS provisioning functionality for both relational and non-relational database engines. Anyone who is interested in database as a service will benefit from this presentation.

This presentation will help people in understanding benefits of database as a service in OpenStack cloud. Which will directly help in increasing the adoption of OpenStack in the market. Since OpenStack is an Open source platform for creating private and public cloud. Increase in OpenStack will directly benefit the open source world.  

Autotest is an open-source project, which provides a framework for fully
automated testing. It is designed primarily to test the Linux kernel, though
it is useful for many other functions such as verifying new hardware and
testing virtualization under Linux platforms.It is composed of a framework
and several testsuites that rely on the core libraries in the framework.
Virt-test is one of the testsuites which is used for testing different Linux
virtualization hypervisors. As Cloud Computing becomes more and more popular
in the world, virtualization, the base of it, is also important increasingly.
So in order to keep the virtualization infrastructure function and stable,
we need a way to test virtualization functions automatically and rapidly,
and virt-test is on this purpose. In this presentation, Yu Mingfei will introduce
this effective and convenient testsuite to you. 

Recently, Amount of data stored in business has been growing nonlinearly. thereby, Storage must be able to store large and mass data and to use stored mass data.
Swift, a part of OpenStack Project, is the open source software that can construct scalable and robustness distributed object storage. Swift Community is now approaching to realize features such as Erasure Coding, Searching, and more.

In this session, He will introduce basics of Swift and Swift's latest information. and he wish to discuss the future of Swift, including Python, cgroups, etc.

Google BigQuery might be the best place to store open data. Where else can people store arbitrarily large datasets, and have them available for instant analysis by others? Realizing its potential and applications, the big data and open source community has been embracing this cloud tool and extending it.

In this session we'll discuss some of the massively large available datasets (whole history of github, httparchive, Freebase, ...), running analytical queries over them in seconds, and how the open source community is embracing the project (data science with pandas and R, log collection with fluentd, ...)

NVM-Express is a standard for high performance PCI-e storage. We're now seeing devices released from many vendors throughout the industry implementing this protocol, and we've learned much since the driver's original inclusion in the Linux mainline kernel over 2 years ago. Keith Busch is one of the core contributors to this driver, and in this presentation will review the standard and how it fits into the Linux kernel, driver and kernel enhancements since it's original inception, and discuss proposed driver and block layer modifications to make full use of this protocol's potential.

When you build a new cloud or modify part of an OpenStack module, you need to test whether the cloud is working properly. However, do you have enough test suite for that?
Tempest is the official OpenStack integrated test suite. Especially, the scenario tests are "through path" tests of OpenStack function, have real-life use cases and can test the interaction between multiple OpenStack services.
This talk includes:

* What is 'Tempest'?
* What is a 'Scenario test'?
* Overview of the current Scenario tests
* What types of things can be tested by the scenario tests?
* The goal
* How to use it
* How to add more scenarios
* Demonstration
* Look at the demo environment
* Execute a scenario test case
* Verify the result

Smartphones have adopted Asynchronous Symmetric Multiprocessors (aSMP) to fulfill two conflicting requirements of the users: long battery life and high performance. As each core has independent frequency/voltage control, aSMP can save energy by lowering frequency of the cores running light applications while not degrading performance of other cores. Unfortunately, the Linux task scheduler does not exploit the energy saving mechanism, since it balances load across the cores regardless of what running applications are. Such pointless load balancing causes energy waste by confusing the scaling governor. This presentation proposes a novel task scheduling technique for aSMP that saves energy and improves performance . The proposed technique schedules applications based on their QoS-sensitivity by using an online classification method which is also proposed in this presentation.

Crowbar is a platform for server provisioning and development from bare metal. It was developed 2 years ago mainly by Dell Engineer as an Open Stack installer. Since then the Crowbar was evolved it’s function by development community. Crowbar becoming a strong tool to setup cloud infrastructure. This time, to enhance the function more and accelerate development, core team decided Crowbar project to be more open to community and changing the name to “Open Crowbar”. This session talks about main reason for this change.

Getting Started! with your Raspberry Pi(Masafumi Ohta, Japanese Raspberry Pi Users Group) - Raspberry Pi is now two years but many of people purchasing and interested Raspberry Pi has no idea to use it in their daily life - they are still wondering 'what Raspberry Pi can and can't'.most of them feels some difficulty with low-speeded APM-based CPU,not so enough RAMs and bare-board (GPIOs) as a electric kit.Masafumi now leading and representing Japanese Raspberry Pi Community and hearing the difficulty and showing the use cases at meet-up (Raspberry Jam) and the conferences in Japan.in this presentation Masafumi will review the use cases through the meet-ups and conferences and discuss what cases would be 'useful' for Raspberry Pi beginners and starters explaining some cases in detail (Home Servers,Audio Devices,Robots,Electric kits..and so on).

Ironic is an burgeoning OpenStack project which provides you provisioning of physical machines.

This talk includes:
* What is 'Ironic'?
* The purpose and the advantages of Ironic
* The mechanism of Baremetal Deployment
* The present development status of Ironic
* The problems should be solved

Precision Time Protocol (PTP) can provide sub-microsecond accurate clock synchronization in a local area network. In order to achieve such accuracy, hardware assisted timestamping is used. Linux kernel is now ready for the hardware timestamping using PTP Hardware Clocks and user-space software, linuxptp, uses the hardware timestamping and provides PTP capabilities on Linux. Fujitsu has worked on linuxptp development and testing for about a year and contributed to improve the functionality and reliability. This presentation introduces linuxptp, including how to use, what is needed, and how to apply it to the systems which need accurate clock synchronization (include mission critical systems).
