随着移动设备，如智能手机，多地在我们的生活中发挥更大的作用，他们需要处理更复杂的任务和计算。Due to limited computational, storage and energy resources, mobile devices have to utilize advanced cloud services in order to complete the tasks at an optimal level. For example, storage services allow mobile devices to save documents in the cloud, and offloading services allow those devices to move tasks to the cloud.
Many companies have provided exemplary storage services, including Amazon’s Cloud Drive service and Dropbox, which allow individuals to tap into applications for large-volume and reliable data storage and exchanges, but mobile devices still lag behind. For instance, Amazon finally released the cloud storage service Cloud Drive for mobile phones, which is available on iOS, Android and Amazon’s app store, but Cloud Drive solely offers read-only versions of files stored in the servers. According to The Verge, “There's no ability to automatically sync or even upload files, and you can't edit or move the files you're viewing.”
