AWS ETL Case Study on Drug Sales Data

Background

A leading US pharmaceutical company possesses extensive sales data gathered from diverse channels such as retail stores, online platforms, and distribution networks.

Challenge

To harness the power of cloud computing, they intend to migrate to the AWS cloud and then utilize AWS cloud services, and leverage its ETL and reporting for their business needs. This initiative aims to unlock valuable insights into drug sales performance, streamline inventory management, and elevate decision-making processes by leveraging cloud-based solutions.

  1. Data Migration Complexity:
    1. Migrating large volumes while ensuring data integrity and minimal disruption.
    2. Balancing resource allocation between migration and daily operations.
  2. Performance and Accessibility:
    1. Maintaining performance and accessibility during migration.
    2. Addressing potential latency issues to ensure business continuity.
  3. Cost Management:
    1. Managing migration and ongoing cloud costs effectively.
    2. Optimizing resource utilization for cost efficiency.
  4. Security and Compliance:
    1. Ensuring data security and compliance in the cloud.
    2. Implementing robust security measures for sensitive data.

Solution

Implement an AWS cloud-based solution to streamline their data processing and analytics workflow.

  1. Data Migration Complexity
    • Prioritize critical data sets and functionalities for phased migration.
    • Utilize AWS Database Migration Service (DMS) for seamless data transfer.
    • Conduct thorough testing to ensure data integrity and minimize disruptions.
  2. Performance and Accessibility
    • Optimize AWS infrastructure configurations for performance.
    • Implement CDNs and caching mechanisms to reduce latency.
    • Monitor performance metrics closely to maintain high availability.
  3. Cost Management
    • Use AWS Cost Explorer and Budgets for cost monitoring.
    • Utilize cost-saving strategies like Reserved Instances and Auto Scaling.
    • Implement cost allocation tags for accurate expense tracking.
  4. Security and Compliance
    • Implement AWS security best practices and robust access controls.
    • Encrypt sensitive data using AWS Key Management Service (KMS) and TLS.
ETL
  1. Data Extraction (AWS Glue):
    • Utilizes AWS Glue to extract data from various sources including relational databases, CSV files, and streaming platforms.
    • Glue crawlers are used to automatically discover and catalog metadata about the datasets stored in Amazon S3 and relational databases such as Amazon RDS.
  2. Data Transformation (Amazon EMR):
    • Leverages Amazon EMR (Elastic MapReduce) to perform large-scale data processing and transformation tasks.
    • Implements Apache Spark and Hive on EMR clusters to cleanse, aggregate, and enrich the raw sales data.
    • Applies transformations to standardize data formats, handle missing values, and calculate metrics such as sales revenue, product profitability, and customer segmentation.
  3. Data Loading (Amazon Redshift):
    • Loads the transformed data into Amazon Redshift, a fully managed data warehouse service.
    • Redshift provides high-performance querying capabilities, allowing analysts to perform complex SQL queries and generate insights rapidly.
    • The data in Redshift is organized into dimensional models optimized for analytics and reporting purposes.
  4. Data Visualization and Analytics (Amazon QuickSight):
    • Implements Amazon QuickSight, a cloud-based business intelligence tool, to create interactive dashboards and visualizations.
    • Analysts and stakeholders can explore sales trends, product performance, geographical distribution, and customer behavior in real-time.
    • QuickSight integrates seamlessly with Redshift, enabling ad-hoc querying and drill-down analysis for deeper insights.
