What is AWS and Why It Dominates the Cloud

Amazon Web Services (AWS) is the world’s most widely adopted cloud platform, offering over 200 fully featured services from data centers globally. Launched in 2006, AWS pioneered modern cloud computing and continues to lead with innovation, scalability, and reliability.

History and Evolution of AWS

AWS began as an internal infrastructure project at Amazon to streamline retail operations. By 2006, it launched its first public service—Amazon S3 (Simple Storage Service)—marking the birth of commercial cloud computing. Since then, AWS has expanded into compute, storage, databases, machine learning, and more.

2006: Launch of Amazon S3 and EC2
2010: Introduction of AWS Management Console
2014: AWS Lambda introduced serverless computing
2020: AWS Outposts brings hybrid cloud capabilities
2023: Expansion into generative AI with Amazon Bedrock

“AWS didn’t just enter the cloud market—it created it.” — TechCrunch, 2022

Core AWS Services Every Developer Should Know

AWS offers a vast ecosystem of services. Understanding the core categories is essential for building scalable, secure, and cost-effective applications.

Compute Services: Powering Your Applications

AWS provides flexible compute options to run applications at any scale.

Amazon EC2 (Elastic Compute Cloud): Virtual servers in the cloud with customizable instance types, OS, and networking.
AWS Lambda: Serverless computing that runs code in response to events without managing servers.
Amazon ECS & EKS: Container orchestration using Docker and Kubernetes.
AWS Fargate: Serverless containers that eliminate server management.

EC2 alone supports over 500 instance types optimized for compute, memory, storage, and GPU workloads.

Storage Services: Secure and Scalable Data Solutions

AWS offers durable, secure, and highly available storage solutions.

Amazon S3: Object storage for data lakes, backups, and static websites. Offers 99.999999999% durability.
Amazon EBS: Block storage for EC2 instances, ideal for databases and file systems.
Amazon Glacier: Low-cost archival storage for long-term data retention.
AWS Storage Gateway: Hybrid storage integration between on-premises and AWS.

S3 now stores over 100 trillion objects and processes millions of requests per second.

Database Services: From Relational to NoSQL

AWS supports a wide range of database engines and models.

Amazon RDS: Managed relational databases (MySQL, PostgreSQL, Oracle, SQL Server, MariaDB).
Amazon DynamoDB: Fully managed NoSQL database with single-digit millisecond latency.
Amazon Aurora: MySQL and PostgreSQL-compatible relational database with 5x the throughput.
Amazon DocumentDB: MongoDB-compatible document database.
Amazon Neptune: Graph database for highly connected datasets.

DynamoDB powers Amazon.com’s shopping cart and handles over 10 trillion requests daily.

AWS Security: Building a Trusted Cloud Environment

Security is AWS’s top priority. The platform follows a shared responsibility model, where AWS manages security of the cloud, while customers manage security in the cloud.

Shared Responsibility Model Explained

This model defines who is responsible for what in the cloud.

AWS Responsibilities: Physical security, hardware, network infrastructure, hypervisor security.
Customer Responsibilities: Identity and access management, data encryption, firewall configuration, OS patching.

For example, AWS secures the EC2 host, but the customer must secure the guest OS and applications.

Key Security Services in AWS

AWS provides robust tools to protect your data and infrastructure.

AWS IAM (Identity and Access Management): Controls user access and permissions with policies and roles.
AWS KMS (Key Management Service): Create and manage encryption keys for data protection.
AWS Shield: DDoS protection for web applications.
AWS WAF (Web Application Firewall): Filters malicious web traffic.
AWS GuardDuty: Threat detection using machine learning and anomaly detection.
AWS Config: Tracks configuration changes and compliance.
