Summary of a great talk by James Hamilton, VP of Engineering from the AWS Re:Invent conference in November 2014. Really clarifies the economy of scale.

Some highlights:
* AWS now has 1 million active customers
* All 14 other cloud providers combined have 1/5th the aggregate capacity of AWS (estimate by Gartner in 2013)
* 449 new services and major features released in 2014
* Every day, AWS adds enough new server capacity to support all of Amazon’s global infrastructure when it was a $7B annual revenue enterprise (in 2004).
* S3 has 132% year-over-year growth in data transfer
* 102Tbps network capacity into a datacenter.

Ivan Zoratti shares some interesting thought on the recent development inside the mysql/mariadb ecosystem. Is mysql a dying tecnology?

I became very interesting in MariaDB when they introduced parallel replication, which gives master-slave and even master-master replication across data centers a winning chance on traditional RDBMs.

With more and more companies moving towards 99,999 uptime, this might become a taken for granted feature of modern RDBMs.

Here is a decent comparison from Kristian Nilson on parallel replication: http://kristiannielsen.livejournal.com/18435.html

A short explanation of what I think are the some of the main advantages of using PHPCR. As you might know JCR has been implemented in Symfony CMF which I would recommend taking a look at if you haven't had the time before.

by looking at metrics for how our codebase change over time, we can derive interesting conclusions about our team processes and the quality of our code. These metrics can be invaluable inputs for making decisions about where we should make improvement, and measuring wheather our improvements really are improving our processes and codebase.
