The document introduces Manila, an OpenStack project for providing shared file systems as a service. It provides an overview of Manila, including that it supports NFS and CIFS protocols and features like ACLs, authentication, snapshots, and different file system types. It describes the Manila architecture including its REST API and processes. It also outlines Manila's roadmap including upcoming features like auto-mount, migration, replication, and growing/shrinking file systems. Sessions on Manila from the OpenStack Tokyo summit are also listed.
This document provides an overview of Ansible, an open source tool for configuration management and application deployment. It discusses how Ansible aims to simplify infrastructure automation tasks through a model-driven approach without requiring developers to learn DevOps tools. Key points:
- Ansible uses YAML playbooks to declaratively define server configurations and deployments in an idempotent and scalable way.
- It provides ad-hoc command execution and setup facts gathering via SSH. Playbooks can target groups of servers to orchestrate complex multi-server tasks.
- Variables, templates, conditionals allow playbooks to customize configurations for different environments. Plugins support integration with cloud, monitoring, messaging tools.
- Ansible aims to reduce complexity compared
10+ Deploys Per Day: Dev and Ops Cooperation at FlickrJohn Allspaw
Communications and cooperation between development and operations isn't optional, it's mandatory. Flickr takes the idea of "release early, release often" to an extreme - on a normal day there are 10 full deployments of the site to our servers. This session discusses why this rate of change works so well, and the culture and technology needed to make it possible.
SQL Server 2017でLinuxに対応し、その延長線でDocker対応やKubernetesによる可用性構成が組めるようになりました。そしてリリースを間近に控えたSQL Server 2019ではKubernetesを活用したBig Data Cluster機能の提供が予定されており、コンテナの活用範囲はさらに広がっています。
本セッションではこれからSQL Serverコンテナに触れていくための基礎知識と実際に触れてみるための手順やサンプルをお届けします。
This document provides an overview and summary of OpenStack Manila. It begins by introducing the presenter and their background. It then states that Manila provides shared filesystem services and supports file-based use cases. It notes that the market for shared file systems is large at $34.6 billion. It provides details on Manila's REST API and integration with other OpenStack services like Nova, Neutron, Cinder. It supports several third-party enterprise storage systems and has 14 storage drivers. The document lists upcoming features in the Mitaka release and concludes by thanking the audience.
This study aims to develop an interactive idea-generation support system that enables users to consider the potential side effects of realizing new ideas.
In idea generation, confirmation bias often leads to an excessive focus on ``convenience,'' which can result in the oversight of unintended consequences, referred to as the ``side effects of convenience.''
To address this, we explored methods to alleviate user biases and expand perspectives through system-supported dialogue, facilitating a broader consideration of potential side effects.
The proposed system employs a stepwise idea-generation process supported by large language models (LLMs), enabling users to refine their ideas interactively.
By dividing the ideation process into distinct stages, the system mitigates biases at each stage while promoting ideas' concretization and identifying side effects through visually supported dialogues.
Preliminary evaluation suggests that engaging with the proposed system fosters awareness of diverse perspectives on potential side effects and facilitates the generation of ideas that proactively address these issues.
