关于裸金属服务器的科普

裸金属服务器再度流行,目前阿里云、华为云、腾讯云等各大厂商都推出了自己的裸金属服务器,那么到底什么是裸金属服务器?裸金属服务器的架构原理是什么?

什么是裸金属服务器?

裸金属服务器(Bare Metal Server)类似云上的专属物理服务器,在拥有弹性灵活的基础上,具有高性能的计算能力。计算性能与传统物理机无差别,具有安全物理隔离的特点。

裸金属服务器再度流行?

目前云计算各大厂商都推出了自己的裸金属服务器,例如:阿里云的弹性裸金属服务器(神龙),腾讯云的黑石服务器,华为的BMS裸金属服务器,为何裸金属服务器再度流行?主要是由于以下几点原因:

物理机才有安全感

部分企业,尤其是大型企业,对于将私有数据中心迁移到公有云有些许担忧,裸金属服务器可以给用户物理机一样的安全感。

性能要求较高

如果用户的应用程序对性能要求敏感,这时候选择裸金属服务器是最佳的选择。

安全监管

某些应用场景对数据安全和监管要求非常严格,虚拟机无法满足用户要求,需要独占物理机,显然裸金属服务器是比较合适的选择。

传统托管的弊端

用户选择传统的服务器托管模式需要耗费更多时间去采购设备、部署等,这个流程比较复杂,周期也比较长,无法及时响应业务变化,这时候裸金属服务器比较合适。

虚拟机与物理机相结合场景

用户上云可能会存在多种形态的计算资源,某些情况下虚拟机无法满足复杂的应用场景,这时候可能就需要需要虚拟机和物理机相结合的场景,裸金属服务器应运而生。

阿里云的裸金属服务器

阿里云弹性裸金属服务器(神龙)是一种可弹性伸缩的高性能计算服务,计算性能与传统物理机无差别,具有安全物理隔离的特点,分钟级的交付周期将提供给您实时的业务响应能力,助力您的核心业务飞速成长。

    You actually make it seem so easy with your presentation but I find this matter
    to be really something which I think I would never understand.
    It seems too complicated and extremely broad
    for me. I’m looking forward for your next post, I’ll try to get the hang of it!

    An intriguing discussion is worth comment. I do think that you should write more on this subject,
    it may not be a taboo matter but usually folks don’t discuss these topics.
    To the next! Kind regards!!
