Method and apparatus for single point of failure elimination for cloud based applications

摘要

pVarious embodiments provide a method and apparatus of providing SPOF elimination for cloud- based applications that provides rules that support rapid elasticity , infrastructure maintenance such as ,for example , software/firmware/hardware upgrades, updates, retrofit , and growth, and preventative maintenance such as , for example, cleaning fan filters and replacing failed hardware components. In particular , the SPOF elimination provided by the method and apparatus is based on network architecture and persistent storage considerations in addition to VM to host instance mappings./p
