How big MNC’S like facebook , google , instagram etc stores , manage and manipulate thousend’s terabyte of data on a daily basis ?
What is Big Data?
Big Data is a collection of data that is huge in volume, yet growing exponentially with time. It is a data with so large size and complexity that none of traditional data management tools can store it or process it efficiently. Big data is also a data but with huge size.
Let’s know about how big MNC’s are storing and using these Data.
Facebook revealed some big, big stats on big data to a few reporters at its HQ today, including that its system processes 2.5 billion pieces of content and 500+ terabytes of data each day. It’s pulling in 2.7 billion Like actions and 300 million photos per day, and it scans roughly 105 terabytes of data each half hour. Plus it gave the first details on its new “Project Prism”.
VP of Engineering Jay Parikh explained why this is so important to Facebook: “Big data really is about having insights and making an impact on your business. If you aren’t taking advantage of the data you’re collecting, then you just have a pile of data, you don’t have big data.” By processing data within minutes, Facebook can rollout out new products, understand user reactions, and modify designs in near real-time.
Google :
A data center normally holds petabytes to exabytes of data. Google currently processes over 20 petabytes of data per day through an average of 100,000 MapReduce jobs spread across its massive computing clusters. How much data does google handle??
This is one of those kind of questions whose answer can never be accurate. On a funnier note, it is like a child asking who come first hen or egg?? which is somewhat similar to asking “how much data does google handle??”
Commonly a PC holds 1TB of storage data and a smartphone holds about 64GB, but as days pass there are newer PCs and smartphones with bigger storage than this. We all know Google is the only one who can answer any kind of question!! We simply conclude that Google knows everything!! And Everything means Everything! Now you must be wondering how much data does google handle to answer all these questions!!??
Google now processes over 40,000 search queries every second on average, which translates to over 3.5 billion searches per day and 1.2 trillion searches per year worldwide.
