What’s BigData

Data has always been Big. The one aspect that differs now, if compared with the past, would be the sheer scale and accessibility of Data, which is the direct result of the super efficient speeds in which data can now be computed. Big Data is therefore an all-encompassing term for any collection of large data sets that were once difficult to process.

Big data requires exceptional technologies to efficiently process large quantities of data within tolerable elapsed times.

NoSQL


The last 25 years of commercial DBMS development can be summed up in a single phrase: "one size fits all". This phrase refers to the fact that the traditional DBMS architecture (originally designed and optimized for business data processing) has been used to support many data-centric applications with widely varying characteristics and requirements. In this paper, we argue that this concept is no longer applicable to the database market, and that the commercial world will fracture into a collection of independent database engines, some of which may be unified by a common front-end


Why NoSQL“The whole point of seeking alternatives [to RDBMS systems] is that you need to solve a problem that relational databases are a bad fit for.” Eric Evans - Rackspace ACID does not scaleWeb applications have different needs

BigData & CloudA Match made in heaven?


Cloud features


Data in the Clouds

As estimated by IDC, by 2020, about 40% data globally would be touched with Cloud Computing.

Cloud adoption is accelerating – the amount of data stored in Amazon Web Services (AWS) S3 cloud storage has jumped from 262 billion objects in 2010 to over 1 trillion objects at the end of the first second of 2012.


While enterprises often keep their most sensitive data in-house, huge volumes of data such as social media data may be located externally.

It is a fact that data that is too big to process is also too big to transfer anywhere, so it’s just the analytical program which needs to be moved—not the data.

"You don't want to be shipping terabytes and petabytes around,". "Keep the data where it is, and then you move the analytics … to that data."


Cloud enables BigDataSome of the first adopters of big data in cloud computing are users that deployed Hadoop clusters in highly scalable and elastic clouds: IBM, Azure, AWS

Cloud computing democratizes big data – any enterprise can now work with unstructured data at a huge scale.Analytics-as-a-service (AaaS) models for cloud-based big data analytics


Drivers for big data on cloud adoptionCost reduction

Managing cloud-based big data is cost-effective, scalable, and fast to build.

Rapid provisioning/time to market

Faster provisioning is important for big data applications because the value of data reduces quickly as time goes by.

Flexibility/scalability

Big data analysis, especially in the life sciences industry, requires huge compute power for a brief amount of time. For this type of analysis, servers need to be provisioned in minutes.


BigData is not always Cloud-appropriate

Low latency realtime data

Virtualization overhead

Multi-tenancy overhead

Scalability

Lack of cloud computing features to support RDBMS

Availability

“Rain cloud” incorporates clouds

Data integrity/privacy

Data can only be accessed by authorized users

Currently, encryption is utilized by most researchers to ensure data privacy in the cloud
