# How New, Resilient Networks Change Data Center Design - **期号**: SRE Weekly Issue #92（2017-10-08） - **作者**: — - **链接**: http://www.datacenterknowledge.com/design/will-data-center-operators-shed-tier-favor-distributed-resiliency ## 简介 This article jumps off from Azure’s announcement of availability zones to discuss a growing trend in datacenters. We’re moving away from highly reliable “tier 4” datacenters and pushing more of the responsibility for reliability to software and networks. ## 正文 ![Paper Craft Red Thermometer Shows Extremely High Temperature on Summer Heatwave Paper Craft Red Thermometer Shows Extremely High Temperature on Summer Heatwave](https://eu-images.contentstack.com/v3/assets/blt8eb3cdfc1fce5194/blt8bc7ebc3f64d0638/6aa16c4d3af861848191713c/Paper_Craft_Red_Thermometer_Shows_Extremely_High_Temperature_on_Summer_Heatwave.png?width=1400&auto=webp&quality=80&disable=upscale) [Cooling](http://www.datacenterknowledge.com/infrastructure/cooling) [Beyond WUE: Assessing Data Center Water Resilience](http://www.datacenterknowledge.com/cooling/beyond-wue-assessing-data-center-water-resilience) [Beyond WUE: Assessing Data Center Water Resilience](http://www.datacenterknowledge.com/cooling/beyond-wue-assessing-data-center-water-resilience) Water stewardship claims and WUE scores don’t guarantee reliability under heatwaves or water shortages. A site-specific resilience assessment matters more. ![Excavator on the construction site with electric piles and substation in the distance Excavator on the construction site with electric piles and
