According to Gartner, “Big Data is high volume, high velocity, and high variety information assets that require new forms of processing to enable enhanced decision making, insight, discovery, and process optimization”.
Big Data consists of vast volumes of data. It plays a far-reaching role in a business on a daily basis. One of its main use involves analyzing data for insights that pave the path for effective decision-making.
Big Data might be a new name, but it has a long standing history. Gathering and storing immense aggregates of information for eventual analysis is an age old practice. The concept gained popularity at the turn of the 21st century when Doug Laney, an industry analyst introduced the now present elucidation of Big Data as the three V’s:
Industry experts in today’s age have gone a mile further to add two more V’s in the definition of Big Data: VARIABILITY and VALUE.
The five V’s of Big Data make it complex to work with. “Big Data” envelops a vast ocean of data generated from diverse sources such as mobile devices, digital repositories, and enterprise applications. It can range from terabytes to even exabytes. The data can be structured or unstructured. Just consider the following figures to get a tiny glimpse of the giant nature of Big Data:
- Facebook gets 10 million new photos uploaded every hour
- Google processes over 24 petaBytes of data every day.
- Twitter tweets ~400 million tweets per day.
Big Data’s significance doesn’t revolve around how much data you have, but what you DO with it. Data from any source can be analyzed to find solutions that enable: cost and time reductions; new product development and offering optimization; and intelligent decision making.
When you add Big Data with powerful analytics, the possibilities are endless.
Big Data + powerful analytics
- Root cause evaluation of failures, issues and defects in near-real time.
- Coupon generation at the point of sale based on customer buying habits.
- Recalculation of entire risk portfolio in minutes.
- Fraudulent behavior detection before damage control.
PAIN POINTS of Big Data in a Traditional Data Center Setup
A traditional data center setup has a lot of gap when it comes to Big Data. Traditional database systems are based on structured data. This traditional data is stored in a fixed format. Examples include Relational Database System (RDBMS) and the spreadsheets. These only give the answers to the questions about what happened. Thus, the problem is not even close to being solved. Unstructured data is the remedy. It fills the gap of structured data. It enhances the ability of an organization, provides deepful insights into the data (including metadata). The role of Big Data is crystal clear – It uses the semi-structured and unstructured data to enhance the data variety gathered from disparate sources like customers, audience and subscribers. The collected data is then transformed into knowledge based information. Data generation is taking place at a lightning speed and traditional database systems are failing to support the demand for heavy data load.
The Solution? AWS CLOUD
The gap of Big Data in a traditional data center setup is easily solvable in a cloud based service such as AWS. You can strainlessly build, secure, and deploy Big Data applications through the broad spectrum of AWS services. Forget procuring hardware and maintaining infrastructure. Instead, focus on ascertaining new insights, solving new problems and building new products. New features are unveiled constantly so you can continue on your journey to leverage the latest technologies without stressing out about making investment commitments in the long game.
The FIVE PILLARS of AWS for Big Data
The five pillars of cost, performance, availability, elasticity and security are the foundation that make it possible for Big Data analytics in AWS to stand tall and high.
Cost – Most AWS services have a pay-as-you-go model. This means that you can easily use Big Data services cost effectively without draining your financial resources. Big Data AWS services such as Kinesis Streams, Lambda, EMR, DynamoDB, ES and ML are just a few examples that let you pay only for what you use. Another major benefit of the pay-as-you-go model is that you get the freedom to perform feasibility studies and experiment with multiple algorithms without emptying your pockets!
Performance – By know you should know that Performance is Everything. AWS Big Data services such as Lambda and ML are equipped with high speed performance. In ML, real-time prediction requests return a response within 100ms. Performance of other Big Data services depend on various parameters such as shard throughput capacity in Kinesis Streams, and type of EC2 instances to run clusters in EMR.
Availability – Durability and availability are key factors in the optimal functioning of AWS Big Data services. Here’s a brief look into a few services providing these crucial functionalities – Kinesis Streams provides high availability and data durability by synchronously replicating data across multiple AWS Availability Zones. Lambda uses replication and redundancy to provide high availability. Amazon Redshift automatically detects and replaces a failed node in your data warehouse cluster. Amazon ES domains can be configured for high availability by enabling the Zone Awareness option.
Elasticity – With scalability and elasticity, you hold the reins to alter the capacities of services according to your needs. The liberty to scale and elasticize are especially essential in handling the humongous nature of Big Data services. In Kinesis Streams, you can increase or decrease the capacity of the stream at any time. Lambda is designed to scale automatically on your command. With Amazon EMR, it is easy to resize a running cluster. DynamoDB is both highly scalable and elastic. There is no advertised limit to the amount of data you can store in a DynamoDB table. In Redshift you can easily change nodes with a few clicks in the console. With ES, you can add or remove instances, and easily modify Amazon EBS volumes to provide room for data growth. Last but not the least, auto scaling is the holy grail that lets you automatically scale EC2 capacity up or down.
Security – BIG Data needs BIG security. Don’t you agree? AWS Big Data services come packaged with building blocks to help organizations structure a secure, flexible, and cost-effective data lake. In Amazon Redshift and EBS, you can enable database encryption for your clusters to help protect data at rest. Moreover, AWS services meet industry-specific compliance standards like PCI DSS, HIPAA, etc. So you can relax and stay rest assured.
AWS Big Data SERVICES
Now that you know a bit (or lot!) about Big Data, it’s time to look at individual services that AWS offers for Big Data analytics. Here’s a gist about each of the service and how they can help you in the quest to solve Big Data problems.
