我准备购买2台ECS服务器，对公网提供web服务，前端利用SLB做流量分发。为了提高容灾能力，计划的是购买同一地域（华东1）不同可用区内的ECS，也就是可用区B一台，可用区F一台。按照这种规划购买，2台ECS会分别位于同一个VPC的两个虚拟交换机下（交换机B和交换机F）。而当我购买RDS for mysql数据库时，发现RDS的产品购买时也必须指定VPC名称和对应的交换机。我选择的RDS版本.....

同一地域，同一VPC下的两个不同可用区（不同交换机）分别买两台ECS，这两台ECS能否内网互通？

在同一地域，同一VPC下的两个不同可用区（不同交换机）分别购买两台ECS，这两台ECS能否内网互通，若能互通，速率如何？即华东1杭州地域，新建一个VPC，在这个VPC下，在可用区G和可用区H分别新建交换机A和交换机B，在交换机A、B分别购买两台ECS：A1、B1.请问这两台ECS是否可以实现内网互通
