ビッグデータ時代のストレージ選択

調査会社451と弊社のWebnar:Big Data Storage: Options & Recommendationsのまとめです。Big data storage size

ビッグデータ/Hadoop対応のストレージの需要は(驚くことに)いまだに4%程度。全体の需要の伸びにも追い付いていないのが現状ではあるが、少しずつ変わりつつある。

元々Hadoopは、バッチ処理中心で安価なローカルディスクを使用するのが一般的であった。

しかしながら、リアルタイム処理、解析等々多様なアプリに使われだした為、色々な種類のストレージが使われ始めた。一例としてNetwork Storageを何に使うかを調べたところビッグデータの伸びが一番大きかった。クラウドであろうがオンプレであろうが各種ストレージを適材適所で使用していく事が成功のカギとしている。Stodare hadoop

こうした環境では異なるストレージ間のコネクタ、複製が必要となってくる。一つの解としてWD Fusionが紹介された(WDFusionについては過去のブログを参照ください)

Introduction to SmartSVN

SmartSVN is a powerful and easy-to-use graphical client for Apache Subversion. There are several clients for Subversion, but here are just a few reasons you should try SmartSVN:

  • It’s cross-platform – SmartSVN runs on Windows, Linux and Mac OS X, so you can continue using the operating system (OS) that works the best for you. It can also be integrated into your OS, via Mac’s Finder Integration or Windows Shell.

  • Everything you need, out of the box – SmartSVN comes complete with all the tools you need to manage your Subversion projects:

  1. Conflict solver – this feature combines the freedom of a general, three-way-merge with the ability to detect and resolve any conflicts that occur during the development lifecycle.

  2. File compare – this allows you to make inner-line comparisons and directly edit the compared files.

  3. Built-in SSH client – allows users to access servers using the SSH protocol. This security-conscious protocol encrypts every piece of communication between the client and the server, for additional protection.

  • A complete view of your project at a glance – the most important files (such as conflicted, modified or missing files) are placed at the top of the file list. SmartSVN also highlights which directories contain local modifications, which directories have been changed in the repository, and whether individual files have been modified locally or in the central repo. This makes it easy to get a quick overview of the state of your project.

  • Fully customizable – maximize productivity by fine-tuning your SmartSVN installation to suit your particular needs: Change keyboard shortcuts, write your own plugin with the SmartSVN API, group revisions to personalize your display, create Change Sets, and alter the context menus and toolbars to suit you. You can learn more about customizing SmartSVN at our ‘5 Ways to Customize SmartSVN’ blog post.

  • Comprehensive bug tracker support – Trac and JIRA are both fully supported.

Multitude of support options – SmartSVN users have access to a range of free support, from refcards to blogs and documentation, the SmartSVN forum and a Twitter account maintained by our open source experts. If you need extra support with your SmartSVN installation, expert email support is included with SmartSVN Professional licenses.

Want to learn more about SmartSVN? On April 18th, WANdisco will be be holding a free ‘Introduction to SmartSVN’ webinar covering everything you need to get off to a great start with this popular client:

  • Repository basics

  • Checkouts, working folders, editing files and commits

  • Reporting on changes

  • Simple branching

  • Simple merging

This webinar is free so register now.

Is Subversion Ready for the Enterprise?

At WANdisco, we firmly believe that Apache Subversion is a commercial quality version control system ready for the enterprise. With everything that Subversion has to offer enterprise users, it’s easy to see why it’s becoming such a popular choice:

  • It’s open source – cost is one of the most commonly-cited reasons for adopting open source solutions such as Subversion, but there are many other benefits. Most notably, open source projects tend to be collaborative efforts between many developers, so users reap the benefit of a team of developers, all with their own particular skills and areas of expertise.
  • It’s an established project – accepted into the Apache Incubator in 2009 and graduating a year later, today Subversion is an Apache Top Level Project maintained by a global community of contributors.
  • It’s the center of a vibrant ecosystem – Apache Subversion users have access to countless additional client tools, GUIs and plugins. Subversion also integrates with most of the major IDEs, including Eclipse and Microsoft Visual Studio.
  • Free community support – another benefit of utilizing open source technology is the transparent, archived communication that makes up an open source project’s mailing lists and forums, including Subversion’s dedicated SVNForum. This communication can be an invaluable source of information for users, and in many instances, a question will have already been asked – and answered – by someone else. If you can’t find the answer you were looking for, ask the community directly. There’s also no shortage of free training resources available online, including webinars, refcards and tutorials.
  • Professional support option – Subversion has an extensive community of users who are always willing to answer queries, but mailing lists and forums aren’t always the ideal place to reach out to when disaster strikes your enterprise deployment. As a long-established open source solution, there are professional support options available for Apache Subversion.

Our professional support services for Subversion includes:

  1. 24-by-7 worldwide coverage
  2. Guaranteed response times
  3. Indemnification coverage
  4. Subversion system health check
  5. 8 hours of free consulting or training

Enterprise training is another option for users who need additional support with their Subversion installation.

Despite all the benefits, there are some potential issues to consider when working with large Subversion deployments. If you’re using multiple SVN repositories across globally distributed teams, you may encounter the following challenges:

  • Loss of productivity when the central server fails and users at remote sites cannot access the latest version of your project.
  • Slow networks encourage developers at remote sites to checkout and/or commit infrequently. This increases the chances of encountering time-consuming conflicts.
  • Unnecessary read operations taking place over the WAN, as users at remote sites repeatedly perform read operations to access the same files. This degrades the performance of both the central Subversion server and the network.
  • Every remote request entails a WAN penalty. Although Subversion clients only send changes to the central server when modifications to existing source code files are committed, when a new file is committed or an existing file is checked out, the entire file is sent over the WAN.
  • When Subversion is implemented with an Apache Web Server as a front-end, and the WebDAV HTTP protocol is used, the WAN penalty can be significant. This is particularly true of commits that consist of a large number of files.

To help enterprises overcome these challenges, we’ve just announced an ongoing series of free webinars. Over the course of each hour-long ‘Scaling Subversion for the Enterprise’ session, our expert Solution Architect Patrick Burma will cover all the issues enterprises can encounter when using multiple Subversion repositories across globally distributed teams. He will also discuss the accompanying solutions from the administrative, business and IT perspectives, and will be available to answer specific questions.

You can register for all of this week’s sessions now:

WANdisco’s February Roundup

This month, we launched a trio of innovative Hadoop products: the world’s first production-ready distro; a wizard-driven management dashboard; and the first and only 100% uptime solution for Apache Hadoop.
