Big Data with Cloud Computing

What is Big Data?

Big Data usually refer to processing/analysing huge amount of data or data set(terabyte, petabyte...etc of data) which take long time to process in RDBMS type of databases. Big Data projects uses lot of technologies and framework to process data. First Google introduced MapReduce framework in 2004 and present day also google uses MapReduce framework to index whole WWW for google search engine. Few other frameworks used for Big Data are massively parallel processing (MPP) databases, data-mining grids, Apache Hadoop Framework etc,.

How cloud computing related with Big Data, that a big question?

For this, we just need to know how this MapReduce works.

Example let consider a scenario that, you have two table with 1TB of data (or) you can say 1Billion record (1000 Million) in each table. Running time for a querying these two tables with complex join condition will take around 30 minutes(approx), might vary depends on your database server capability. MapReduce framework have a strategy to handle this situation. Strategy is simple, big task is split-out and given to multiple people, so task will be done soon. 

What is iCloud?

From the series of Apple Inc products and services like iPhone, iPad, iPod, iOS, iTunes, iAd, iBookStore here come up with the new one iCloud, free cloud service for his customers.

Advantages of iCloud:

Nowadays it’s hectic to keep all your data updated across all your devices. iCloud helps to keep your data updated automatically to all your devices. This can be done by wirelessly either in Wi-Fi or 3G (based on user configuration). So users no need to worry about plug-in or transferring data between devices like iPad, iPhone and iPod. Changes made to your data in one device will automatically update to your other apple devices. For example photo which taken in your iPhone will be pushed to your PC automatically.

iCloud provides free storage space about 5GB to store user data and synchronize data between devices between our other devices like iPhone, iPad, iPod and Mac or Windows PC. And also it allows us to configure up to 10 devices for each user. Moreover space required to store the  music, books, apps purchased from apple are not included in this 5GB, hence user will get dedicated 5GB storage to store their personal Mail, Documents, and Backup data. In the case of user need more storage space for their use, and then they can extend their storage space by paying extra price.
