建议工作负荷

The CenturyLink Cloud Platform has been orchestrated to run diverse workloads to address a wide array of business needs. The information below outlines some of the common uses for our platform.

开始免费试用

云原生应用的存储

建立在网络服务基础上的大多数新应用需要对象存储的灵活性和高可用性。使用CenturyLink对象存储来托管多媒体文件和更多其他文件——均具备高可用性。

静态数据的长期存储

对象存储是静态数据站外存档的理想选择。以低月费存储文件,并可随时使用HTTP将其取回。

安全的托管文件传输

使用电子邮件传输大文件会带来问题,而很多免费实用程序却又无法提供企业通常需要的安全和保护。CenturyLink的对象存储是一种更为安全的替代选择。

极致灵活性

CenturyLink的云存储方法在很多方面提供了更大的灵活性。决定每种情境需要哪种类型的存储,然后指定支持使用案例所需的自动化DR/BC的类型。您不会被“小型”、“中型”或“大型”实例等预设方案所束缚。

拥有高I/O访问和数据保持能力的高级存储

要求严苛的应用组件(例如数据库的数据存储)需要高I/O以提供具有吸引力的用户体验。正因如此,CenturyLink产品目录中加入了这些高端选项。

Dynamically Adjust Disk Size as Required

任何虚拟机的存储需求都不是静态的。随着企业需求的变化,已部署虚拟机的存储属性也可能发生改变。CenturyLink使您能够在需要时自行进行做出改变。
