谷歌在推出App Engine之初曾表示,该产品启动阶段允许1万名开发者注册,以后将逐步开放.在试用期,开发者的空间限于500M以下,每天的流量不超过10G.在此条件下,谷歌希望本服务能够支持每月500万的页面阅览量.谷歌当前预计,用户每月仍能够通过App Engine每月浏览500万的网页.
微软此前也已推出了Azure平台服务.Azure被认为是微软的云计划战略,也被认为是下一个阶段与谷歌、亚马逊等进行竞争的重要平台武器.微软已表示,该公司正计划建立Azure云计算服务分级协议,用户可以通过不同额度的付费获得不同层级的服务标准.但截至目标,微软还没有向接受Azure云计算服务的用户收取费用.
