AWS Data Analytics Training - AWS Data Engineering

1. Introduction to AWS Data Engineering Welcome to your journey into the dynamic world of AWS Data Engineering! In this presentation, we'll demystify what data engineering entails, explore why Amazon Web Services (AWS) is the platform of choice for modern data solutions, and uncover the vast career opportunities awaiting you in this exciting field. We'll also touch upon real-world applications and outline a clear learning path to transform you from a beginner to an AWS Data Engineering expert. +91-7032290546

2. Core Concepts of Data Engineering Data Ingestion, Transformation, & Storage Batch vs. Stream Processing Structured vs. Unstructured Data Discover the difference between processing large volumes of data at intervals (batch) and processing data as it arrives in real-time (stream), and when to use each. Learn how raw data is collected, cleaned, structured, and securely stored for analysis. This involves understanding various data sources and appropriate storage solutions. Understand the characteristics of organized (tables, databases) and unorganized (text, images, video) data and how to handle them effectively. ETL vs. ELT Workflows Importance of Data Pipelines Explore the traditional Extract, Transform, Load (ETL) paradigm versus the modern Extract, Load, Transform (ELT) approach, which leverages cloud scalability. Grasp the critical role of automated data pipelines in ensuring data consistency, reliability, and accessibility for business intelligence and machine learning. +91-7032290546

3. Key AWS Services for Data Engineers AWS offers a comprehensive suite of services tailored for data engineering needs. Each service plays a crucial role in building robust and scalable data solutions. Amazon S3 Object storage for building scalable data lakes, ideal for raw data and foundational storage. AWS Glue Serverless ETL service for data preparation, cataloging, and transformation. Amazon Redshift Cloud data warehouse for petabyte-scale analytics and business intelligence. Amazon Kinesis Real-time data streaming service for processing large streams of data. AWS Lambda Serverless compute service for triggering data processing and automation. +91-7032290546

4. Designing Scalable Data Pipelines Designing effective data pipelines is crucial for efficient data processing. It involves selecting the right processing method, integrating services seamlessly, and ensuring data quality throughout. Best Practices Implement modularity, fault tolerance, and idempotency for robust pipeline design. Batch vs. Stream Choose based on latency requirements: batch for periodic, stream for immediate processing. Service Integration Combine S3 for storage, Glue for ETL, Lambda for triggers, and Redshift for warehousing. Automation Orchestrate workflows using AWS Step Functions or Apache Airflow for reliability. Data Quality Implement validation, monitoring, and alerting to maintain high data integrity. +91-7032290546

5. Hands-On Project Architecture Let's outline a practical project: real-time user clickstream analysis. This project will integrate several AWS services to capture, process, store, and visualize user behavior data. Data Storage in Redshift: Load the transformed data from S3 into Amazon Redshift for analytical querying and reporting. Project Flow: Real-time User Clickstream Data: Simulate or collect user click events from a website or application. Visualization with QuickSight: Connect Amazon QuickSight to Redshift to create interactive dashboards for analyzing user behavior, popular pages, and conversion funnels. Data Ingestion: Use Amazon Kinesis Data Firehose or Kinesis Data Streams to ingest clickstream data efficiently. Firehose can directly deliver data to S3. Alerts & Automation: Set up Amazon CloudWatch alarms to monitor data pipeline health and automate responses using AWS Lambda for failure notifications or data quality issues. ETL with AWS Glue: Process and transform raw clickstream data stored in S3 using AWS Glue ETL jobs. This involves cleaning, enriching, and structuring the data. +91-7032290546

6. Security, Cost & Optimization Tips IAM Roles and Permissions Implement the principle of least privilege using IAM roles for data services to control access securely. Data Encryption Ensure data is encrypted both at rest (e.g., S3, Redshift) and in transit (e.g., SSL/TLS) for compliance and security. Cost Monitoring with Cost Explorer Regularly use AWS Cost Explorer to track and analyze spending on data services, identifying areas for optimization. Optimizing Glue Jobs and Redshift Queries Tune Glue job configurations and optimize Redshift queries for performance and cost efficiency (e.g., sort keys, distribution keys). Managing Data Lifecycle in S3 Utilize S3 lifecycle policies to automatically transition data to lower-cost storage classes or delete old data. +91-7032290546

7. Certification & Career Roadmap Achieving an AWS certification can significantly boost your career. The AWS Certified Data Analytics – Specialty is highly recommended for aspiring data engineers. Certification & Learning: Career & Job Market: • Focus on understanding core concepts beyond memorization for the AWS Certified Data Analytics – Specialty exam. • Tailor your resume to highlight AWS data engineering skills, projects, and any relevant certifications. • Prioritize hands-on labs and building personal projects to solidify your practical skills and gain real-world experience. • Top companies actively hiring AWS Data Engineers include Amazon, IBM, Accenture, Deloitte, and various tech startups. • Participate in workshops and online courses that offer practical scenarios. • Explore freelancing platforms and remote job boards for flexible work opportunities in the data engineering space. +91-7032290546
