Circular Replication in MySQL [31005]
Replication is a hot topic in MySQL 5.6
Jeremy Smyth writes, "Replication is a hot topic in MySQL 5.6, and for good reason: There are many excellent features that make it a strong well-supported feature, from the new Global Transaction Identifiers (GTIDs), to simplified replication configuration and automated failover using MySQL Utilities (now available in alpha as a separate download).
The simplest topology consists of a master server that accepts changes, and slaves that replicate those changes from the master. A common requirement is for a network to have multiple servers that accept changes and replicate to each other. This is possible by means of circular replication, where each master is also the slave of another master, in a circular fashion. However, this configuration is prone to certain problems..."

WAN Optimization Part 1: TCP Limitations [30875]
Network Computing, April 29th, 2013
"While WAN optimization and data acceleration have existed for years, there are misconceptions around the underlying premise, the technology, and the differences between the various offerings. Understanding each of these points is important because many major IT initiatives, such as hybrid clouds, data replication for active/active data center configurations and improved disaster recovery, and data center interconnect (DCI), place even greater emphasis on the WAN.
To help clarify the issues, I'm going to look at data acceleration technologies in a series of blogs. I'll examine the problem and the approaches to improving WAN performance. I'll also examine some of the deployment issues and options around this technology, such as its role within a software defined data center, appliances or services, and the value of virtual vs. physical implementations..."
