Presence of Data Analytics in Your Life

The amount of data being generated and gathered is expanding and accelerating substantially as society becomes more digital. As a result, it becomes difficult to analyze this constantly expanding data using conventional analytical tools. This is where Data Analytics comes into action.

Data Analytics tools and technologies offer opportunities and challenges for analyzing data efficiently so you can better understand customer preferences, gain a competitive advantage in the marketplace, and grow your business.

What is Data Analytics?

Data analytics is the process of converting raw data into actionable insights. It encompasses a variety of tools, technologies, and procedures that utilize data to identify patterns and solve issues. Data analytics can influence business processes, enhance decision-making, and promote business expansion.

Why is Data Analytics important?

Data Analytics has a key role in improving your business as it is used to gather hidden insights, generate reports, perform market analysis, and improve business requirements.

  • Gather Hidden Insights – Hidden insights from data are gathered and then analyzed with respect to business requirements.
  • Generate Reports – Reports are generated from the data and are passed on to the respective teams and individuals to deal with further actions for a high rise in business.
  • Perform Market Analysis – Market Analysis can be performed to understand the strengths and weaknesses of competitors.
  • Improve Business Requirement – Analysis of Data allows improving Business to customer requirements and experience.

How can the Cloud Help?

The number of IoT-connected gadgets in our daily lives is rapidly expanding.

Businesses today rely heavily on cloud data analytics to help them deal with the difficulty of keeping up with the current rate of data generation, utilization, and storage. Cloud data analytics can help firms make better decisions by following data patterns and eliminating the need for assumptions. Taking into account all of the cloud’s possibilities as well as the possible risks, organizations are increasingly adopting cloud for its many benefits, with data being one of the most crucial decision considerations.

The objective is to ensure that data can be processed and analyzed more quickly with the assistance of cloud experts. Cloud offers access to various services like servers, data analytics, Artificial Intelligence, Machine Learning and much more. It provides an advanced features to process and analyze the huge amount of data in a day to day world.

Why Prefer Cloud for Data Analytics?

Cloud technology can be used to build entire data lakes, data warehousing, and data analytics solutions.

Without spending a lot of money on hardware, it is possible to acquire virtual machines and install software to manage data replication, distributed file systems, and entire big data ecosystems.

Many cloud providers, including Amazon Web Services, began to observe that customers were deploying virtual machines to implement big data tools and frameworks. And then based on this observation, Amazon began to develop offerings with everything installed, configured, and ready to use services such as Amazon EMR, Amazon S3, Amazon RDS, Amazon Athena, and many others.

Another significant advantage of cloud-based data analytics is the ability to cease paying for infrastructure resources when they are no longer required. This happens often in data analytics since running reports on huge data processes is done once in a while. And in the cloud, you can accomplish so simply by launching a server or other service, utilizing it to get the necessary report, storing it, and then shutting down all of the other services.

AWS Data analytics

Amazon Web Services (AWS) offers a comprehensive platform of managed services to facilitate the development, security, and scalability of end-to-end big data applications. AWS offers the infrastructure and resources to take on your next big data project, whether your applications need real-time streaming or batch data processing.

Why AWS Data Analytics?

  • No hardware to procure: The hardware and the servers will be managed by AWS.
  • No infrastructure to maintain and scale: The customers just need to store, process, and analyze big data.
  • Advanced Analytical Tools: AWS has an ecosystem of analytical solutions that are specifically designed to manage the escalating volume of data and provide business intelligence.

  • Pay-as-you-go: Depending on the amount of input data and the sort of analysis, analyzing large datasets necessitates a significant amount of computing power. This characteristic of big data workloads is optimal for the pay-as-you-go model of cloud computing, in which applications can be readily scaled up or down based on demand.
  • Global Infrastructure: Additionally, AWS offers access to the many different geographic Regions that AWS provides, as well as the flexibility to employ additional scalable services that support the development of complex big data applications. These additional services include Amazon Simple Storage Service (Amazon S3) to store data, and AWS Glue to orchestrate jobs to move and transform that data. Another important service is AWS IoT, which is used by connected devices to interact with cloud applications and other connected devices.

Hands-on Demonstration

Moving an Airline data From S3 to AWS Redshift and Query the data via Redshift Editor

Solution Steps:

Step 1: Create a file (data.txt) with the below content. Feel free to add more rows to the data. The different attributes in the data set are year, month, date, actual departure time, scheduled departure time, origin, and destination airports in the same order. From this data, we would be interested in figuring out the best and the worst airports based on the number of flights getting delayed.


Step 2: Create a bucket in S3 and upload the data.txt file to it.

Step 3:  Go to the IAM Management Console and click on Roles.

Step 4: Select Redshift as the service which is going to use this role, click on Redshift – Customizable and click on Next: Permissions.

Step 5:  Select AmazonS3ReadOnlyAccess Policy from the list and click on Next.

Step 6: Enter the role name as Role4RedShift-S3RO and click on Create role.

Step 7: Click on the Role and note down the Role ARN to be used along with Redshift later.

Step 8: Go to the Redshift Management Console and click on Create cluster.

Step 9: Give the cluster a name. Select dc2.large as this fall under the free trial Node type.

Step 10: Select the number of nodes as 1, again as this fall under the free trial Number of Nodes.

Step 11: Give the username and password, make sure to note it down.

Step 12: Under the Cluster permissions,” select the IAM Role created in the previous steps and click on Add IAM role.

Step 13: The rest of the default options are good enough. Try to explore the different options and click on Create cluster.

Step 14: Initially, the Redshift cluster would be in a creating status. Click on Cluster.

Step 15: Finally, the cluster would be in available status and is ready for the queries to be run in a few minutes.

Step 16: Click on the Editor tab in the left pane. Select the Cluster, enter the Database name as dev, and finally the user and password. Click on Connect to database.

Step 17: In the Query tab, paste the below query and click on Run to create the onetime table.

create table ontime (
  Year integer,
  Month integer,
  DayofMonth integer,
  DepTime  integer,
  CRSDepTime integer,
  Origin varchar(120),
  Dest varchar(120)

Step 18:  Now, the table must be populated with the data. Again, in the same Query tab, copy the below command and click on Run. Make sure to change the bucket name and the IAM Role ARN. In a few seconds, the data in the table will be populated. In the Query results, it should indicate the status Completed.

copy ontime
from 's3://airline-details-01/data.txt'
iam_role 'arn:aws:iam::910563908074:role/Role4RedShift-S3RO'
delimiter ',' region 'us-west-2';

Step 19: In the same Query tab, execute the below query to see if the data is populated.

select * from onetime;

Step 20: Execute the below query to get the number of flights delayed from each of the origin. This will give the best and the worst airports based on the number of flights getting delayed.

select Origin, count(*) as Count from ontime where DepTime > CRSDepTime group by Origin order by Count desc;
