Service Level Agreements for Cloud Storage Douglas B Terry Vijayan Prabhakaran Ramakrishna Kotla Mahesh Balakrishnan Marcos K Aguilera Hussam AbuLibdeh Microsoft Research A foolish consistency is the hobgoblin of little minds. Hellerstein Abstract Distributed consistency is a perennial research topic in recent years it has become an urgent practical matter as well The research literature has focused on enforcing various 64258avors of consistency at the IO layer such as li Data consistency Asynchronous writeback for user data Write back forced after fixed time intervals e g 30 sec Write back forced after fixed time intervals eg 30 sec Can lose data written within time interval Maintain new version of data in temporar Doug Terry.
