云原生服务器是否是serverless的另外一种说法?

@YuPengZTE 我理解云原生服务器应该是针对云原生特性,定制过的硬件服务器,比如定制的os。定制过的特殊网卡等

云原生服务器,目前,能找到的资料很少。

从原文中给出的定义来看:

云原生服务器是指基于专用硬件、芯片,利用软硬融合虚拟化等技术将负载或任务转移,提升资源使用效率、用户体验和整体性能的新型服务器。

硬件层面偏向于硬件加速,硬件呈现;
软件层面偏向于负载或任务转移,和serverless要解决的问题类似。

从硬件虚拟化的历程来说:

  1. 硬件通用化,屏蔽硬件差异,用户使用硬件的模型变得简单;
  2. 提升硬件性能,通过定制硬件解决效率问题,同时提高了性能,节省了资金,但是对用户呈现定制化的硬件,用户体验是下降的,到此第一个周期结束;
  3. 为了提升用户体验,又开始新一轮的硬件通用化,此时的硬件通用化已经到了一个新的台阶上;
  4. 通过定制硬件解决效率问题,第二个周期结束;

可以看到,这是一个螺旋上升的过程。
服务器的硬件加速、硬件呈现只是其中的一个环节;
把此环节加上serverless,定义成云原生服务器,可能有待商榷。
