A recent presentation confirmed the existence of the proprietary distributed technology that will automatically move 
and replicate the load between Google's mega data centers when traffic and hardware issues arise. Perhaps this was done to counter the issues of lagtime when Gmail was down..who knows? The platform is known as Spanner.
Google fellow Jeff Dean hinted about Spanner in the classic Google manner during a conference this summer and has now confirmed its existence in a presentation (PDF) delivered at a symposium earlier this month. .Dean's presentation calls it a "storage and computation system that spans all our data centers [and that] automatically moves and adds replicas of data and computation based on constraints and usage patterns." This includes issues and constraints related to bandwidth, packet loss, power, resources, and "failure modes".
Google is intent on scaling Spanner to between one million and 10 million servers, encompassing 10 trillion (1013) directories and a quintillion (1018) bytes of storage. And all this would be spread across "100s to 1000s" of locations around the world.
Thats a hell lot of data and power granted to a single corporation which will be housing an exabyte of the world's data across thousands of custom-built data centers.
Lets see how this unfolds..

With lots of curious readers asking me how to practice hacking and from where to start,Damn Vulnerable Web App 
(DVWA) is great application to plunge yourself in.DVWA is a PHP/MySQL web application that is damn vulnerable..literally. Its main goals are to be light weight, easy to use and full of vulnerabilities to exploit and it successfully achieves those :P . And frankly it can be used to learn or teach the art of web application security.
The DVWA is bundled with the following type of vulnerabilities-
- SQL Injection
- XSS (Cross Site Scripting)
- LFI (Local File Inclusion)
- RFI (Remote File Inclusion)
- Command Execution
- Upload Script
- Login Brute Force
WARNING !! (
Shamelessly ripped off from official statement :P )
It should come as no shock..but this application is damn vulnerable! Do not upload it to your hosting provider's public html folder or any working web server as it will be hacked. It's recommend that you download and install XAMP onto a local machine inside your LAN which is used solely for testing. You can download DVWA 1.0.4 here:
Download DVWA Keep learning..
