Solaris 的猝死与永生
The sudden death and eternal life of Solaris
2017 — 2019，它一次次回到首页

导读
这是 DTrace 作者之一 Bryan Cantrill 撰写的纪念文章，回顾 Oracle 收购 Sun 后大规模裁员、Solaris 商业版本实质终结的经过，以及 Solaris 团队的技术遗产（DTrace、ZFS 等）。文章同时指出其开源后继者 illumos 仍在社区中延续这些技术。
为什么经久不衰：它既是一份关于一个伟大操作系统如何消亡的一手历史记录，也提醒人们 DTrace、ZFS 等创新通过开源在 Linux 和 illumos 中获得了永生。

Solaris 商业版虽死，开源的 illumos 及其各发行版仍然活跃可用
评论里对 Solaris 的怀旧情绪有点跑偏了。是的，Oracle Solaris 已死，但 illumos 更好、开源、还活着。你现在就能用上 ZFS、mdb、DTrace 和 zones。illumos 只是基础构建块，通常运行其发行版：SmartOS（Joyent 的云虚拟化管理程序）、OmniOS CE（面向裸机服务器的精简发行版）、OpenIndiana（类似传统 OpenSolaris，带 GUI）、Tribblix。用户群虽比 Linux 小，但正如 FreeBSD 之于 Netflix 和 WhatsApp，用与众不同的 OS 反而能给公司带来优势。

There seems to be a lot of odd nostalgia for Solaris in the comments here and on twitter. I think that's missing the point of the article. Yes, Oracle Solaris is dead. But illumos is better, open source, alive and here to stay. You can use illumos today, right now, and have your ZFS, mdb, DTrace and zones. It really is open source and we're a community using and improving it. For 7 years now already. As illumos is only the basic building block of the operating system (but unlike linux includes kernel + basic userland) one usually runs one of the distributions: - SmartOS, developed by Joyent as a cloud hypervisor. Supports zones, KVM and lx-branded linux containers. [1] - OmniOS CE, a minimal distribution targeted for bare metal server installations [2] - OpenIndiana, similar to the traditional opensolaris. If you care about GUI this is probably the one. [3] - Tribblix, modern components with retro style [4] Sure, the user base is smaller than Linux. But that is also true for FreeBSD which is used by Netflix and Whatsapp. Running a different OS than most other people can give your company an advantage and I know that ZFS and zones have done that for mine.

技术再优秀也敌不过市场现实，几乎无人实际使用导致其商业失败
归根结底 Sun/Oracle 得靠 Solaris 赚钱来发工资。你的公司会部署 Solaris 吗？当然不会——如今几乎没人用，w3techs 显示 Solaris 在 Web 服务器中占比仅 0.0005%。大家都说它好（确实有些技术很惊艳），却几乎没人真的在用，这总有原因。我尊重 Solaris 团队工程师的杰出工作，ZFS 和 DTrace 让技术世界变得更好，但世界用脚投了票，Solaris 没能过关。

At the end of the day, Sun/Oracle has to be able to make revenue from Solaris for them to keep paying those peoples' salaries. Is your startup / company deploying on Solaris? Nope of course you aren't - who is?! Pretty much nobody nowadays - w3techs.com shows Solaris at 0.0005% for webservers for example. Everyone talks about how great it is(to be sure there are some small bits that are pretty dang amazing) - yet for some reason nearly no one actually DOES use it! Perhaps there is a reason for that. Lord knows I have many battle scars from the many real world rough edges that never seemed to get less fundamentally shitty(for starters: path_to_inst and smf I'm looking right at you!) I definitely respect the amazing work of some of the engineers on the Solaris team back in the day. ZFS and DTrace being two that have made the tech world by in large a better place either directly or thru inspiration. And Linux and the BSDs are definitely better for those selective code gifts! But nonetheless, the world voted with their feet, and Solaris didn't make the cut.
内部政治使 Solaris 被绑死在衰落的 SPARC 上，错失 x86 转型
Solaris 消亡的一个重要原因是它成了 Sun 内部政治势力强大的 SPARC 部门反自我蚕食努力的牺牲品。这把 Solaris 的命运与迅速衰落的 SPARC 绑在一起，阻止了对 x86 版本的认真投入。随着 Solaris 在主流 x86 硬件支持上越来越落后，2002-4 年间 Solaris 开发者间流传一个笑话：在 Solaris 里跑一个 Linux 内核实例，用它代理对各种 Solaris 不支持的硬件的请求。

One of the major aspects of Solaris demise was that it fell victim to the anti-cannibalization efforts by the extremely politically strong SPARC division inside Sun. That bound the Solaris fate to the [rapidly falling] fate of the Sun SPARC and prevented any serious investment into the development of the x86 version. As Solaris was falling more and more painfully behind in support of popular x86 hardware a running joke ca. 2002-4 from the Solaris dev guys was - to have an instance of Linux kernel with its drivers running inside the Solaris instance and use that Linux instance to proxy requests to the various otherwise unsupported by Solaris hardware.
批评 Oracle 收购扼杀了创新，同时推荐 Cantrill 的演讲
Bryan Cantrill 的演讲非常精彩，十年前看他讲 DTrace 至今印象深刻，推荐去看。悲哀的是，我们生活在一个做出优秀创新技术的公司被 Oracle 这种公司吞掉的世界——后者主要靠欺骗无知的高管和董事会而存在。

Bryan Cantrill give a great lecture. I saw him give an overview of DTrace a decade or more ago and remain impressed. Check him out. https://www.youtube.com/results?search_query=bryan+cantrill It's sad that we live in a world where a company doing good , innovative and useful tech is gobbled up by a company like Oracle who should not exist and do largely on their ability to con ignorant senior management and even more ignorant boards of directors. Is there ever a technical reason to use Oracle? If there is what percentage of Oracle sales does it account for? Ie if it really is non-zero I bet it's a single digit percentage. Woeful company from the top down is their reputation and they've earned it.
