Software infrastructures for mobile cloud computing

点击翻译按钮获取中文摘要

"Cloud Computing" is a broad term that encompasses applications/functionality delivered as services over the internet and the software/hardware infrastructure to host them. This "utility computing model" (John McCarthy, 1961), allows individuals and organizations to purchase virtualized hardware (Infrastructure as a Service, IaaS), software platforms (Platform as a Service, PaaS) or applications/functionality (Software as a Service, SaaS) in a pay-as-you-go manner, comparable to the metered purchase of electricity, gas or water. While seen traditionally as a means for organizations to outsource IT infrastructure, cloud computing can also be used to provide the billions of mobile handsets (mobile/smart phones) with additional resources. While mobile handsets are nowadays heavily used for data communication most notably SMS and basic internet services like email and browsing, their limited computational resources restrict their access to applications/ functionality delivered as web services. To overcome this challenge Mark Baccue proposed the idea of Mobile Cloud Computing, which is based on the concept of using cloud-hosted software components (e.g. proxies) to aid mobile handsets in accessing web services.
