轻量应用服务器和ECS云服务器的定位不同
举例来说:阿里云ECS云服务器类似于一台放在云端的可以自主选择配置的空白电脑主机,需要自己选择CPU、内存、硬盘、带宽配置并自行安装操作系统,适合有一定互联网建站经验和服务器运维基础的用户。而轻量应用服务器相当于你购买已经安装好操作系统的电脑主机,适合对服务器操作不太熟练的新手用户。

1、轻量应用服务器 :
是可快速搭建且易于管理的轻量级云服务器;提供基于单台服务器的应用部署,安全管理,运维监控等服务,一站式提升您的服务器使用体验和效率。轻量应用服务器 是 IaaS 产品,但是提供定制化应用镜像且有可视化控制台可以操作,不怕新手不会用。轻量应用服务器精简了一些 ECS 的功能,比如说安骑士。把安全组的操作也做了适当减法更适合用户操作。

2、云服务器ECS:
是阿里云提供的性能卓越、稳定可靠、弹性扩展的IaaS(Infrastructure as a Service)级别云计算服务。云服务器ECS免去了您采购IT硬件的前期准备,让您像使用水、电、天然气等公共资源一样便捷、高效地使用服务器,实现计算资源的即开即用和弹性伸缩。阿里云ECS持续提供创新型服务器,解决多种业务需求,助力您的业务发展。

二、轻量应用服务器与ECS云服务器的特点不同:
1、轻量应用服务器特点:
快速启动:30秒一键启动您的应用

一站式体验:域名解析、网站发布、服务器管理等操作单界面集成,一站式功能体验

精选镜像:阿里云自主研发和精选市场镜像双重选择,为您提供优质镜像体验

丰富应用:持续提供多种应用功能,帮助您便捷的管理、配置、分析应用

由以上特点可以看到,轻量应用服务器最大的优点就是上手简单,可以轻松搭建以下六种场景应用:

相对于ecs云服务器动辄20余款实例规格,轻量应用服务器只有5款基本配置,对于选择困难症的新手用户非常友好,一目了然,根据自己需求进行选择即可

前面我们说过轻量应用服务器可以一键安装各种网站环境与开发环境等个人应用,而且在配置页面我们还可以切换系统镜像,用php语言程序搭建网站的选择CentOS,用ASP的可以选择windows系统镜像:

而且楚狂人今天发现了一个福利:香港节点的轻量应用服务器价格特别优惠,同等配置比大陆节点优惠一半还多,不知道是暂时的还是长期如此。有需要的朋友可以快点下手,手快有手慢无哦!

2、云服务器ECS特点:
稳定:实例可用性达 99.95%,云盘采用99.9999999%可靠性设计,自动宕机迁移,自动快照备份,数据恢复更方便

弹性:支持分钟级别创建1000台实例,多种弹性付费选择更贴合业务现状,同时带来弹性的扩容能力,实例与带宽均可随时升降配,云盘可扩容

高安全:免费提供 DDoS 防护、木马查杀、防暴力破解等服务,通过多方国际安全认证,ECS云盘支持数据加密功能

高性能:单实例最高可选88vCPU,内存704GB,单实例性能最高可达到700万PPS网络收发包,35Gbps带宽

易用性:丰富的操作系统和应用软件,通过镜像可一键简单部署,同一镜像可在多台 ECS 中快速复制环境,轻松扩展

可拓展性:ECS 可与阿里云各种丰富的云产品无缝衔接,可持续为业务发展提供完整的计算、存储、安全等解决方案

三、阿里云轻量应用服务器和ECS云服务器哪个好?
说到轻量应用服务器和ECS云服务器哪个好,其实在同等配置下,两者的功能并没有差别。价格方面也基本持平,只是因为轻量服务器更多的是照顾到入门级用户,所以更多强调易用性,可选配置方面也简化到只有5款基本配置,从而对于大型企业级用户或者更多需要自主配置的用户来说略有不足。所以建议新手个人级用户可以选择轻量应用服务器或者ECS云服务器,但是企业级用户或者熟练掌握服务器操作的用户优先选择ECS云服务器。

Domain Bias in Web Search (by Microsoft Research)

This paper uncovers a new phenomenon in web search that we call domain bias — a user’s propensity to believe that a page is more relevant just because it comes from a particular domain. We provide evidence of the existence of domain bias in click activity as well as in human judgments via a comprehensive collection of experiments. We begin by studying the difference between domains that a search engine surfaces and that users click.

China’s Hebei expands testing area for Intelligent Connected Vehicles 

Cangzhou City of north China’s Hebei Province has expanded testing of intelligent connected vehicles (ICVs) on new public routes, making it one of the largest road networks nationwide for testing autonomous vehicles.

Cangzhou has newly earmarked roads with a length of 407.3 km for ICV testing, bringing the total length to 636.9 km, said the municipal public security bureau.

The ICV road testing will involve more real-world traffic scenarios, such as transportation hubs, business zones, residential communities, schools, and parks.

In recent years, Cangzhou has speeded up its efforts to develop the ICV industry. The city has achieved strategic cooperation with Internet companies, including Baidu, on autonomous driving and intelligent transportation.

China allowed local governments to arrange road tests for ICVs, which cover different degrees of autonomous driving, in April 2018. An increasing number of cities, including Beijing, Shanghai, and Chongqing, have issued license plates for road tests of ICVs.

Alibaba Pledges US$15.5 Billion To China’s ‘Common Prosperity’ Push

Alibaba Group has committed RMB100 billion (US$15.5 billion) to finance 10 initiatives promoting “common prosperity” in China, supporting a nationwide push towards a fairer society.

To this end, Alibaba has set up a dedicated task force, spearheaded by Group Chairman and CEO Daniel Zhang, to see through each initiative by 2025, the company said in a statement on Friday.

The task force will focus on technology innovation, economic development, creating high-quality jobs, care for vulnerable groups, as well as launching a RMB20 billion Common Prosperity Development Fund that will help cut income inequality in Alibaba’s home province of Zhejiang.

“Alibaba is a beneficiary of the strong social and economic progress in China over the past 22 years. We firmly believe that if society is doing well and the economy is doing well, then Alibaba will do well,” said Zhang in the statement.

Hangzhou-headquartered Alibaba’s pledge is one of the largest made by a private sector company this year in alignment with China’s efforts to reduce income inequality.

China’s campaign to reduce the country’s wealth gap dates back to the foundation of the Communist Party but has come into greater focus this year after President Xi Jinping pledged to make solid progress towards common prosperity by 2035 after eradicating extreme poverty.

pilot program is already underway in Zhejiang province to narrow its income gap by 2025, creating an olive-shaped social structure by making middle-income households the mainstay of its economy.

New China-Europe freight train route links China’s Chongqing with Ukraine

A freight train loaded with 50 containers of machinery and equipment left southwest China’s Chongqing Municipality Sunday for capital of Ukraine, marking the launch of Chongqing’s new freight train route.

The freight train is scheduled to pass through the border port of Erenhot in north China’s Inner Mongolia Autonomous Region, and will reach its destination in mid-September.

Previously, exports from Chongqing to Ukraine had to go through Belarus or Poland rather than heading directly for Ukraine. The new route is the municipality’s first direct international freight train route to Kyiv. It is expected to further facilitate trade between Europe and the western regions of China.

Chongqing is a primary hub for China-Europe freight trains. The Yuxinou (Chongqing-Xinjiang-Europe) railway, which was the first China-Europe freight train route, saw 1,359 trips in the first half of 2021, up over 50 percent year on year, according to the port and logistics office of the municipal government.

Since the railway was put into operation in 2011, Yuxinou has launched more than 30 routes, connecting over 40 cities across 26 countries, and the routes have recorded over 8,000 freight train trips.
