高级计算机体系结构设计及其在数据中心和云计算的应用What are WSCs ?WsCs currentlypowertheservicesoffered bycompanies such as Google, Amazon, Yahoo, andMicrosoft's online services division. They differ significantly from traditional datacenters:- They belong to a single organization- Use a relatively homogeneous hardware and system softwareplatform-Sharea common systems managementlayer
高级计算机体系结构设计及其在数据中心和云计算的应 用 What are WSCs ? • WSCs currently power the services offered by companies such as Google, Amazon, Yahoo, and Microsoft’s online services division. • They differ significantly from traditional datacenters: – They belong to a single organization – Use a relatively homogeneous hardware and system software platform – Share a common systems management layer
高级计算机体系结构设计及其在数据中心和云计算的应用What are WsCs ?: Often much of the application, middleware, andsystem software is built in-house compared to thepredominance of third-party software running inconventional datacenters. Most importantly, WsCs run a smaller number of verylarge applications (or Internet services).The common resource management infrastructureallows significant deployment flexibility
高级计算机体系结构设计及其在数据中心和云计算的应 用 What are WSCs ? • Often much of the application, middleware, and system software is built in-house compared to the predominance of third-party software running in conventional datacenters. • Most importantly, WSCs run a smaller number of very large applications (or Internet services). • The common resource management infrastructure allows significant deployment flexibility
高级计算机体系结构设计及其在数据中心和云计算的应用What are WSCs ?The requirements of:- homogeneity- single-organization controlenhanced focus oncostefficiency... motivate designers to take new approaches in constructingand operating these systems
高级计算机体系结构设计及其在数据中心和云计算的应 用 What are WSCs ? • The requirements of: – homogeneity – single-organization control – enhanced focus on cost efficiency . motivate designers to take new approaches in constructing and operating these systems
高级计算机体系结构设计及其在数据中心和云计算的应用Not Just a Collection of ServersCentral point: datacenters powering Internet servicesare no longer simply a miscellaneous collection ofmachines co-located in a facility and wired uptogether.. The software running on these systems, such as Gmailor Web search services, execute at a scale far beyonda single machine or a single rack: they run on nosmaller a unit than clusters of hundreds to thousandsof individualservers
