Big data is defined as a collection of data sets created by users and machines alike. These data sets are not only created by users, but also by satellites, GPS, sensors, automated response and many more.
All this data is aggregated as one to form a data set. The size of these data sets can only be measured in quintillion bytes. The challenge that big data presents IT organizations with is that it becomes hard for managed data centers to organize, sort and manage these large boulders of data.
On the flip side, they also present organizations with a lot of unexplored business opportunities.
Big Data is the trend
Big Data is the trend in IT these days that’s making quite a thunder. It is undoubtedly one of those rare mushrooming technologies that encompass not only the scope but also the intricacy.
All around us there seems to be a data flood of sorts and at the nucleus of it all is Big Data. Anyone who is anyhow associated with any avenue of IT is trying to analyze this big one.
To put it in comprehensible terms Big Data is an assimilation of humongous data listings, tables and information that is highly complex in nature and it is this multiformity that makes it a tedious task for data management tools to derive at a logical conclusion.
Google deals with many layers in their varied centres that collect data, and needless to say there are a host of things that can probably head the wrong way.
There could be a sudden machine meltdown, a router collapse, a hard drive malfunction or any other unexplained breakdown and therefore it becomes imperative that the software employed should spell allegiance and dependability.
The hardware fallout in the form of lethargic machinery, loss of information and so on can be dealt with by replication.
Google mainly employs two mechanisms to withstand latency, namely cross request and within request adaptation.
The former scrutinizes behavior that occurred recently thereby manipulating future appeals, whereas the latter mechanism deals with the uninclined subsystems in purview.
It was in the year 2004 that Google released a white paper titled Map Reduce, which was deemed to be a programming pattern that helps process large data clusters. Over the years, Google has shrewdly equipped itself with advanced programs and patterns to manage future surge in big data.
For Google to be able to efficiently handle the voluminous amount of information or data, they employ many services, namely Big Table, Map Reduce and Cluster Scheduling System.
These services that Google uses helps them to resolve varied issues, however they carry the risk of bringing to the fore many cross cluster problems. Google has therefore armed itself with what they have constructed to be called a “Spanner”.
This is a storage mechanism for large volumes of data and this prevails across all of their data centres. The ‘spanner’ has been uniquely designed in a way that aids continuous duplication across all the data centres.
Dapper is a tool used by Google to enable them to supervise on a continuous basis as well as debug. Each server that is up and running aids monitoring, debugging and online profiling.
In recent times, Google has been doing some work on providing a foundation for deep learning. Deep Learning is a branch of algorithms that automates deriving substantial sense from raw data.
It picks information from both marked and unmarked data and contains many Central Processing Units.
The adventurous phenomenon called the Big Data is revolutionizing the data is talked about and handled. Companies are going to great lengths and breaths to collate, interpret and store the massive volumes and Google as a forerunner is doing a rather amazing job at handling their big data.
