line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;">那么，我不禁要问，尽管云计算有如此多的好处，那么如今有多少公司采用云计算来提供服务呢？我们不难发现，其实在大多数据的公司内部，采用云计算的客户并不多，那么是什么原因让用户依然坚持在原有的内部部署上呢？下面我们来看以下几点原因。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif;

line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;">云安全一直是用户比较在意的问题，谁能够将敏感的数据长期放在云中呢？是的，iCloud存储的照片都有被泄露的可能，更别说人们对那些云服务提供商的怀疑了。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif;

line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;">存放在云中的数据，企业用户的控制能力降低，不能够在第一时间对所掌握的数据进行管理，而且云服务提供商如果出现宕机的情况，企业用户就无所适从了。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif;

line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;">以前的基础设施投资</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif; line-height: 25px;

line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;">在云计算出现之前，大多数企业都通过自己购买基础设施来搭建服务平台，利用云计算虽然可能降低TCO。但是原有的基础设施投资却浪费掉了，这使得很多企业很难直接选择云服务，而放弃原有的基础设施投资。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif;

line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;">2、可靠性</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif; line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;"><br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"/></p><p style="margin-top: 0px;

line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;">可靠性是关于云计算非常有争议性的问题，有足够的证据表明，云计算运行的时间比内部部署时间要长，但是怎么可靠性不如内部部署呢？</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif; line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;"><br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"/></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif; line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;">云计算可靠性</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif; line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;"><br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"/></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif; line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;">云服务提供商可以自由的上调他们的价格，而不同的价格可能面对着不同的服务，而你在选择云计算后，可能面临着多方面的瓶颈，所以这个可靠性方面并没有单独购买基础设施有保障。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif; line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;"><br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"/></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif; line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;">3、综合考虑</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif; line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;"><br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"/></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif; line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;">还有一个关键的原因，就是企业的业务非常多，一些业务并不能够放在云端，所以很多企业不可能为了一个单独的业务就移动到云端，这样，这个业务很难与其他业务形成一个统一的管理平台，在这种情况下，移动到云就不是一个非常好的选择了。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif; line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;"><br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"/></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: 'Helvetica Neue', Helvetica, 'Hiragino Sans GB', 'Microsoft YaHei', Arial, sans-serif; line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;">总结：云计算各种奇思妙想的解决方案可以解决很多问题，但是对于当前的企业用户来说，虽然云计算有这种那种的好处，但是总体来说还有很多瓶颈，这仍然需要一个长期的发展才能够实现。</p><p><br/></p>
