『OpenStackの導入事例/検証事例のご紹介』NTTドコモ様 検証事例:OpenStack Summit 2014 Paris 講演「Design and Operation of OpenStack Cloud on 100 Physical Servers (NTT DOCOMO)」
講師:伊藤 宏通(日本仮想化技術 CTO)
先日パリで開催したOpenStack Summit 2014 Parisで講演した内容を日本語でお伝えいたします。
You will face many problems when you start designing your OpenStack Cloud because of a lack of full design architecture information. For example, there are many Neutron plugins, but it is difficult to choose the best plugin and its configuration to get a high throughput of a Virtual Machine (VM) and achieve a High Availability (HA) of L3 Agent. Also, we couldn’t find information for how much computing resource (CPU, Memory and HDD) is required for management and operation servers (e.g. API, RabbitMQ, MySQL and Monitoring etc.).
We built OpenStack Icehouse Cloud on 100 physical servers (1600 physical cores) without using commecial software, and did several performance and long-run tests to address these problems.
In this talk, we will present performance comparison of Neutron ML2 plugin implementations (Open vSwitch and Linux Bridge), tunnelling protocols (GRE and VXLAN) and physical network configurations (Network Interface Bonding and Server Side Equal Cost Multi Path) to achieve 10Gbps at a VM, and the L3 Agent HA we implemented. Also, we will present how much computing resource we used and each server loads to operate the cloud. Finaly, we will share our Ansible Based OpenStack deployment and management tool.
Key topics include:
- Performance comparison of OSS Neutron ML2 plugins (Open vSwitch and Linux Bridge) and tunneling protocols (GRE and VXLAN)
- Performance comparision of redundant network configurations (Network Interface Bonding and Server Side Equal Cost Multi Path)
- HA of L3 Agent (ACT/STBY) we implemented
- Ansible based deployment/operation tools
- Items we must watch for OpenStack operation
- Hardware specifications and resources we used to operate the Cloud
We will share a full design architecture and hardware sizing information for a large scale cloud and prove OSS based Neutron can handle a hundred servers.

La limitation des ressources financières, humaines et technologiques agit comme un frein majeur au développement du concept de ville intelligente. Des solutions ont été trouvées par Shawinigan pour pallier à ces restrictions, et continuer à améliorer la diffusion de l’information, tant à l’interne qu’auprès des citoyens.

Enterprise Infrastructure Software - Industry Control PointJesse Wu
Database management systems and operating systems are two of the largest and most important segments within the enterprise infrastructure software market. Together they accounted for over $50 billion in market size in 2014 and act as control points since the top three players in each segment make up a large combined market share percentage.

This document contains a shot list for a film titled "The Last Chapter". It details 79 shots across 38 scenes. The shots include locations, camera angles, durations and basic descriptions of the actions occurring in each shot. Overall, the shot list follows the story of a couple, Oscar and Lily, and documents their daily life together as well as activities they engage in from a bucket list. It shows their relationship developing and moments they share up until the film's conclusion.

It lists his educational background, research experience, skills, publications, and membership in professional societies. Dr. Zekry has over 186 publications and his areas of expertise include electronics, communication engineering, renewable energy, and semiconductor devices.
This document discusses 5G and multi-access edge computing (MEC). The key points are: 1) 5G can achieve latency of 100ms while 4G is 300ms, and 5G bandwidth is 20Gbps compared to 4G's 1.29Gbps; 2) MEC deployed close to users on 5G can achieve even lower latency of under 10ms; 3) MEC integrated with 5G can enable new applications for IoT, VR/AR with high speed and low latency.

Here are the key points from the AT&T presentation on their "Network AI" framework:
- AT&T is developing an open source framework called "Network AI" to drive their software-defined network transformation.
- The goal is to apply AI/machine learning techniques to continuously optimize their network performance. This will be done by collecting massive amounts of network data and using it to train ML models.
- As part of this effort, AT&T is contributing several open source projects to the Linux Foundation like Airship, Akraino, and Acumos. Airship provides tools for deploying OpenStack and Kubernetes on the edge, while Akraino is an edge computing framework. Acumos allows for developing and
