Reconfiguring Replicated Atomic Storage: A Tutorial

We live in a world of Internet services such as email, social networks,

web searching, and more, which must store increasingly larger volumes of

data. These services must run on cheap infrastructure, hence they must use

distributed storage systems; and they have to provide reliability of data for

long periods as well as availability, hence they must support online reconfiguration

to remove failed nodes and add healthy ones. The knowledge

needed to implement online reconfiguration is subtle and simple techniques

often fail to work well. This tutorial provides an introductory overview of

this topic, including a description of the main technical challenges, as well

as the various approaches that are used to address these challenges.
