一、Bridged（桥接模式） 转http://www.linuxidc.com/Linux/2016-09/135521p3.htm 什么是桥接模式？桥接模式就是将主机网卡与虚拟机虚拟的网卡利用虚拟网桥进行通信。在桥接的作用下，类似于把物理主机虚拟为一个交换机，所有桥接设置的虚拟机连接到这个交换机的一个接口上，物理主机也同样插在这个交换机当中，所以所有桥接下的网卡与网卡都是交换模式的，相互可以访问而不干扰。在桥接模式下，虚拟机ip地址需要与主机在同一个网段，如果需要联网，则网关与DNS需要与主机网卡一致。其网络结构如下图所示： 接下来，我们就来实际操作，如何设置桥接模式。 首先，安装完系统之后，在开启系统之前，点击“编辑虚拟机设置”来设置网卡模式。 点击“网络适配器”，选择“桥接模式”，然后“确定” 在进入系统之前，我们先确认一下主机的ip地址、网关、DNS等信息。 然后，进入系统编辑网卡配置文件，命令为vi /etc/sysconfig/network-scripts/ifcfg-eth0 添加内容如下： 编辑完成，保存退出，然后重启虚拟机网卡，使用ping命令ping外网ip，测试能否联网。 能ping通外网ip，证明桥接模式设置成功。 那主机与虚拟机之间的通信是否正常呢？我们就用远程工具来测试一下。 主机与虚拟机通信正常。 这就是桥接模式的设置步骤

What design/pattern to use for a Client application using multiple providers?

由 自作多情 提交于 2020-01-05 02:10:49
问题 This is a design related question. Lets say we have a public API called ClientAPI with a few web methods like CreateAccount, GetAccount. Depending on the customer, we use a number of different providers to fulfil these requests. So say we have ProviderA and ProviderB and ProviderC. ProviderA has a method signature/implementation of CreateAccount that needs (Firstname, Lastname) only and creates an account with ProviderA. ProviderB has a method signature/implementation of CreateAccount that
