ORIGIN OF AWS

Early Beginnings (2002)

• 2002: Amazon.com introduced its first web service, named Amazon.com Web Services.
• What it did: Amazon introduced early web services (SOAP- and XML-based APIs) that allowed developers to programmatically interact with Amazon’s product catalog. These laid the foundation for what would later become AWS.

Official Launch (2006)

• 2006: Amazon Web Services (AWS) officially launched.
• Core Services Introduced:
  1. Amazon Elastic Compute Cloud (EC2): This service lets users rent virtual servers to run their applications. Essentially, it gives you a cluster of virtual computers that you can use just like physical ones.
  2. Amazon Simple Storage Service(S3): Provides scalable and reliable storage for data, making it easy to store and retrieve any amount of data at any time.

Rapid Growth (2007–2010)

2007: By this year, AWS had attracted nearly 180,000 developers who signed up to use its services.
2010: Amazon.com, the retail website, moved its web services to AWS, meaning that the same infrastructure that AWS customers use is also powering Amazon.com.

Expansion and Adoption

• Growth of Services: Since its launch, AWS has continuously expanded its range of services, which now includes a wide variety of cloud computing solutions like databases, machine learning, analytics, and more.
• Global Reach: AWS has grown its global infrastructure, offering services from numerous data centers worldwide.
• Customer Base: AWS serves millions of customers, ranging from startups and small businesses to large enterprises and public sector organizations.

Why AWS Became Popular

• Scalability: Users can easily scale their applications up or down based on demand.
• Pay-as-you-go: Customers pay only for what they use, which can be more cost-effective than maintaining their own servers.
• Reliability: AWS offers high availability and robust security features.
• Innovation: Constantly adding new features and services to meet evolving customer needs. Key Takeaways AWS started as a tool for developers to interact with Amazon’s product catalog. It officially launched in 2006 with EC2 and S3 as the core services. By 2010, Amazon.com itself was running on AWS, showcasing its reliability and scalability. Today, AWS offers a wide range of services globally and serves millions of customers across various industries.

WHAT IS AWS?

AWS (Amazon Web Services) is a comprehensive and widely adopted cloud platform offered by Amazon. It provides on-demand cloud computing resources and services such as computing power, storage, and databases to individuals, companies, and governments on a pay-as-you-go basis. AWS enables scalable and flexible solutions, ranging from web hosting and application development to data processing and machine learning. It supports a vast ecosystem of tools and integrations, making it a popular choice for various cloud computing needs.

AWS GLOBAL INFRASTRUCTURE

AWS Global Infrastructure is designed to provide high availability, reliability, and scalability for applications and services worldwide. It consists of multiple regions and availability zones to ensure that your applications are always available and can recover quickly in case of failure.

Key Components of AWS Global Infrastructure

• AWS Regions
• AWS Availability Zones
• Edge Locations
  

AWS Regions

An AWS Region is a physical location around the world where AWS clusters its data centers. Each AWS Region is a separate geographic area that provides full redundancy and connectivity to the network. As of 2025, AWS has 33 launched Regions with over 100 Availability Zones worldwide, with more announced.

Characteristics of AWS Regions:

• Geographic Distribution: AWS Regions are located in different parts of the world, such as North America, Europe, Asia Pacific, and South America, to reduce latency and ensure data sovereignty.
• Independent Resources: Each region operates independently, which means resources in one region are not automatically replicated to another region.
• Data Residency: Users can choose a specific region to meet legal and compliance requirements regarding data residency.

AWS Availability Zones

AWS Availability Zones (AZs) are distinct locations within an AWS region. Each region has multiple availability zones, and each availability zone consists of one or more discrete data centers with redundant power, networking, and connectivity.

Characteristics of Availability Zones:

• Isolation and Redundancy: AZs are isolated from each other to prevent a failure in one zone from affecting others. They are connected through low-latency links to enable high availability and failover support.
• High Availability: By deploying applications across multiple AZs within a region, you can achieve high availability and fault tolerance. If one AZ fails, the others can continue to operate.
• Scalability: AZs allow you to scale applications and resources easily within a region.

Edge Locations

Edge Locations are data centers that are used to cache and distribute content closer to end users, providing lower latency and faster access times. They are part of AWS’s content delivery network (CDN), Amazon CloudFront.

Characteristics of Edge Locations:

• Content Delivery: Edge locations are used to deliver web content, videos, and other large files to users with minimal latency.
• Global Reach: There are many edge locations worldwide, ensuring that content can be delivered quickly to users, no matter where they are located.
• Security and DDoS Protection: Edge locations also help protect against Distributed Denial of Service (DDoS) attacks by distributing traffic across multiple locations.
