这篇博客将介绍WPF中的虚拟化技术. 1. Data Virtualization 通常情况下我们说数据虚拟化是指数据源没有完全加载,仅加载当前需要显示的数据呈现给用户.这种场景会让我们想到数据分页显示,当需要特定页面的数据时,根据页数请求相应数据. WPF没有提供对Data Virtualization原生态的支持,当时我们可以使用Paging相关技术来实现.在我先前的博客WPF 实现 DataGrid/ListView 分页控件中有介绍. 2. UI Virtualization 是针对数据…

写在转发之前: 几个月以前,在北大机房和燕园大厦直接拉了一根光钎.两端彼此为校园内公网IP.为了方便连接彼此机房,我做个一个VPN server在燕园的边界,北大机房使用client拨回.两个物理机房分别分配了两个不同的网段,利用三层路由将两端通过VPN隧道进行互联. 后来找SDN相关的工作,面试过程中被问到了VXLAN.最近在了解aliyun VPC产品.试着思考了一下内部实现原理. 跨地域三层VPC互联与北大燕园的模型,基本差不多.但是,跨地域二层互联呢? 应该怎么办. 于是带着这个疑问,了…

本章为读者提供了Linux虚拟化中流行技术的深刻见解,以及相较于其他同类技术的优势特点.本书共有14章,囊括了KVM虚拟化中的各个方面,从KVM的内部构造开始,并包括了诸如软件定义网络(SDN),性能调节和优化以及P2V(physical to virtual migration)等高级内容. 在本章中,我们将学习以下内容: Linux虚拟化和它的基本概念 为什么我们要使用Linux虚拟化 Hypervisor/VMM 在云计算中,Linux虚拟化可以为你提供什么 公有云和私有云 TIP:在开始…

在第二章,你了解了KVM的内部结构:在本章中,您将了解如何将Linux服务器设置为虚拟化主机.我们正在讨论将KVM用于虚拟化并将libvirt作为虚拟化管理引擎. KVM开启了虚拟化并利用你的服务器或工作站来运行虚拟机.从技术术语来说,KVM是一组针对具备虚拟化扩展的x86架构硬件的内核模块:被加载后,它可以将Linux服务器转化为虚拟化hypervisor.可加载模块包括kvm.ko,它提供了核心虚拟化功能,以及一个处理器相关的模块,如kvm-intel.ko或者kvm-amd.ko. NOT…
