Middleware-based database replication

Emmanuel Cecchet, George Candea, Anastasia Ailamaki
2008 Proceedings of the 2008 ACM SIGMOD international conference on Management of data - SIGMOD '08  
The need for high availability and performance in data management systems has been fueling a long running interest in database replication from both academia and industry.  ...  Second, we distill a few research topics that provide low-hanging fruit for closing these gaps, in the realms of middleware design, consistency models, availability, and system evaluation.  ...  Improving Performance via Replication Database replication is typically used to improve either read performance or write performance, while improving both read and write performance simultaneously is a  ...

High availability using virtualization

Federico Calzolari, Silvia Arezzini, Alberto Ciampa, Enrico Mazzoni, Andrea Domenici, Gigliola Vaglini
2010 Journal of Physics, Conference Series  
A complete infrastructure has been developed to install operating system and middleware in a few minutes.  ...  A new approach to the problem can be offered by virtualization. Using virtualization, it is possible to achieve a redundancy system for all the services running on a data center.  ...  A backup and a recovery facility infrastructure, intended to backup the system at scheduled intervals and restore a backup when a disaster occurs, can remedy this kind of problem.  ...

A self-organizing publish/subscribe middleware for dynamic peer-to-peer networks

M.O. Junginger, Yugyung Lee
2004 IEEE Network  
Peer-to-peer needs new middleware technologies and counterparts to the widely established CORBA, EJB, COM+, and messaging systems products.  ...  We address this need with our P2P Messaging System, which focuses on high-performance group communication based on a publish/subscribe model.  ...  The activated backup link is converted to a regular link, and new backup links are established to restore the ring completely.  ...
