Abstract
Google offers a variety of Internet services that require user authentication. These services rely on a single-sign-on service, called Google Accounts, that has been in active deployment since 2002. As of 2006, Google has tens of applications with millions of user accounts worldwide. We describe the data management requirements and architecture for this serv |

Abstract
Achieving highest possible scalability is a complex combination of many factors. This
paper presents a pattern language that can be used to make a system highly
scalable.

2008-10-17 18:03 The universal scalability model is a single equation expressed in terms of two parameters α and β. The relative capacity C(N) is a normalized throughput given by:
C(N) = N / ( 1 + αN + βN (N − 1) )
where N represents either:
1. (Software Scalability) the number of users or load generators on a fixed hardware configuration. In this case, the number of users |

2008-10-16 11:21 ZooKeeper is a high available and reliable coordination system. Distributed applications use ZooKeeper to store and mediate updates key configuration information. ZooKeeper can be used for leader election, group membership, and configuration maintenance. In addition ZooKeeper can be used for event notification, locking, and as a priority queue mechanism. It's a sort of central nervous system for distributed sy |

Software design patterns are an emerging tool for guiding and documenting system design. Patterns usually describe software abstractions used by advanced designers and programmers in their software. Patterns can provide guidance for designing highly scalable distributed systems. Let's see |
