📝 What's On Deck?

❓ What Is AWS Data Engineering?

AWS Data Engineering is the process of designing and maintaining data systems using Amazon Web Services.

Data Engineers build pipelines that move information from different source systems into data lakes, warehouses, and analytical applications.

⚙️ Main Responsibilities

• Collect data from multiple business systems
• Build batch and streaming ingestion pipelines
• Store raw and processed datasets
• Transform data using SQL, Python and Spark
• Validate data accuracy and completeness
• Automate processing workflows
• Monitor failures and performance
• Apply cloud security and cost management practices

🏗️ AWS Data Engineering Architecture

An AWS data pipeline commonly includes five stages: ingestion, storage, processing, analytics, and monitoring.

For example, an e-commerce company might collect daily order files in Amazon S3, transform them with AWS Glue, query curated files with Athena, and load reporting datasets into Redshift.

📚 Core AWS Data Engineering Technologies

🗂️ 1. Amazon S3 – Data Lake Storage

Amazon Simple Storage Service (S3) is an object storage service widely used for cloud data lakes.

Data Engineers use S3 to store raw files, processed datasets, logs, exports, and analytics-ready data.

Important S3 Concepts

• Buckets and objects
• Object keys and prefixes
• Storage classes
• Bucket versioning
• IAM policies and access control
• Encryption
• Lifecycle management
• Data partitioning
• Integration with AWS Glue and Athena

s3://my-company-data/
    raw/
        orders/
        customers/
    processed/
        orders/
    curated/
        daily_sales/
        customer_metrics/

🐍 2. Python for AWS Data Engineering

Python is an important programming language for AWS Data Engineering because it supports data processing, scripting, API integration, and automation.

Python Topics to Learn

• Variables and data types
• Conditional statements and loops
• Functions and modules
• Lists, dictionaries, tuples and sets
• File handling
• Exception handling
• Working with JSON and CSV
• Boto3 for AWS automation

import boto3

s3 = boto3.client("s3")

bucket_name = "my-example-bucket"
local_file = "sales.csv"
object_key = "raw/sales.csv"

s3.upload_file(
    local_file,
    bucket_name,
    object_key
)

print("File uploaded successfully")

Replace the sample bucket name with an existing S3 bucket. The code requires the Boto3 library, valid AWS credentials, and permission to upload objects.

🔥 3. PySpark for Big Data Processing

Apache Spark is a distributed data processing framework. PySpark provides Python APIs for Spark.

AWS Data Engineers can use PySpark to process large datasets with AWS Glue or Amazon EMR.

Key PySpark Topics

• Spark architecture
• SparkSession
• DataFrames
• Transformations and actions
• Filtering and joins
• Aggregations
• Spark SQL
• Partitioning and performance
• Parquet file processing

from pyspark.sql import SparkSession
from pyspark.sql.functions import sum

spark = SparkSession.builder \
    .appName("DailySales") \
    .getOrCreate()

data = [
    ("2026-11-01", 1500),
    ("2026-11-01", 2000),
    ("2026-11-02", 3000)
]

df = spark.createDataFrame(
    data,
    ["sales_date", "amount"]
)

result = df.groupBy("sales_date") \
    .agg(
        sum("amount").alias("revenue")
    )

result.show()

The result aggregates total revenue for each date.

⚙️ 4. AWS Glue – Serverless Data Integration

AWS Glue is a managed, serverless data integration service used to discover, prepare, transform, and move data.

It supports ETL workflows, metadata discovery, Spark-based processing, and integration with multiple AWS data services.

Main AWS Glue Components

• Glue Data Catalog: Stores metadata about datasets
• Glue Crawlers: Discover data schemas
• Glue Jobs: Execute transformation logic
• Glue Studio: Visual job development
• Glue Triggers: Initiate jobs
• Glue Workflows: Coordinate related processing activities
• Glue Data Quality: Evaluate data quality rules

🔧 Typical Glue ETL Pipeline

A crawler can infer the schema of CSV or Parquet files in Amazon S3 and register table metadata in Glue.

A Glue ETL job can then read the data, clean records, perform transformations, and write the output back into S3.

🔎 5. Amazon Athena – Query S3 Using SQL

Amazon Athena is a serverless interactive query service used to analyze data in Amazon S3 using SQL.

Athena can use table metadata stored in the AWS Glue Data Catalog.

Athena Learning Topics

• Athena architecture
• Glue Data Catalog integration
• Creating external tables
• SQL joins and aggregations
• Partitioned tables
• Parquet and columnar formats
• Query performance and cost optimization
• Workgroups and query result locations

SELECT
    order_date,
    COUNT(*) AS total_orders,
    SUM(order_amount) AS revenue
FROM sales_orders
GROUP BY order_date
ORDER BY order_date;

This query assumes a cataloged sales_orders table with matching columns.

🌊 6. Amazon Kinesis – Real-Time Streaming

Amazon Kinesis services help ingest and process streaming data.

Streaming pipelines are useful when information arrives continuously from applications, clickstreams, devices, or operational systems.

Important Concepts

• Kinesis Data Streams
• Stream producers and consumers
• Shards and throughput considerations
• Amazon Data Firehose delivery streams
• Lambda integration
• Streaming data validation
• Monitoring lag and processing failures

⚡ 7. AWS Lambda – Serverless Automation

AWS Lambda allows developers to run code in response to events without directly managing servers.

A common data engineering use case is performing lightweight validation or triggering downstream processes when a new file is uploaded to S3.

Typical Lambda Use Cases

• S3 upload notifications
• File metadata validation
• Event-driven pipeline triggers
• API integrations
• Lightweight transformations
• Workflow automation

def lambda_handler(event, context):

    for record in event.get("Records", []):

        bucket = record["s3"]["bucket"]["name"]
        key = record["s3"]["object"]["key"]

        print("Bucket:", bucket)
        print("Object:", key)

    return {
        "statusCode": 200,
        "body": "Event processed"
    }

Configure an appropriate S3 event notification to invoke this function. Production implementations should also handle URL-encoded object keys, errors, retries, and duplicate events.

🗄️ 8. Amazon Redshift – Cloud Data Warehousing

Amazon Redshift is a managed cloud data warehouse designed for analytical SQL workloads.
