Practices,我们的实践,8/29/2020,11,CIeNET PROPRIETARY,8/29/2020,12,Guideline: Dont Over-Engineer in the Beginning 初始阶段不要过度设计,We dont buy extra hardware: 没有购买新硬件 Not all applications need a powerful CPU and large memory to support high transact

5、ion rates. We havent implement HA：暂不实施高可用 Not all applications need 24x7 availability. We only backup data for controller nodes: 仅备份控制节点 Not all data need extremely high security. We dont engineer for extremely concurrent usage of all users: 不考虑所有用户同时使用等极端情况 Not all user will use the system at same
