Recognizing the potential of this infrastructure, Amazon launched its first web services in 2002, initially offering tools and APIs for developers to access the Amazon.com catalog. However, the vision for AWS soon expanded towards providing more fundamental infrastructure services.
A pivotal moment came in 2006 with the launch of Amazon S3 (Simple Storage Service) and Amazon EC2 (Elastic Compute Cloud). S3 offered scalable object storage, while EC2 allowed users to rent virtual servers, fundamentally changing how businesses could access and pay for computing resources. These services marked the true emergence of AWS as a public cloud provider and were among the first to popularize the pay-as-you-go cloud computing model. Early services also included Amazon SQS (Simple Queue Service), launched for public use in 2004.
Throughout the following years, AWS rapidly expanded its portfolio of services, introducing solutions for databases (like Amazon RDS and DynamoDB), networking (like Amazon VPC and Route 53), content delivery (Amazon CloudFront), and more. The company also focused on global expansion, establishing data centers in various regions worldwide. AWS played a significant role in popularizing concepts like Infrastructure as a Service (IaaS) and later, Platform as a Service (PaaS) and Serverless computing with services like AWS Lambda. To foster skills and partnerships, AWS launched its certification program in 2013 and the AWS Partner Network (APN) in 2014. Today, AWS is a dominant force in the cloud computing market, serving millions of customers globally.
Key industries reliant on AWS infrastructure
The flexibility, scalability, and broad range of services offered by AWS have led to its adoption across a multitude of industries. Many organizations, from startups to large multinational corporations and government agencies, leverage AWS to power their operations and drive innovation.
The technology sector itself is a major user, with software companies, SaaS providers, and tech startups building and hosting their applications on AWS. The ability to scale resources up or down quickly is particularly beneficial for businesses with fluctuating demand or rapid growth. In the media and entertainment industry, AWS is used for content creation, storage, processing, and global distribution of streaming video and other digital media. The platform's content delivery networks and media services are crucial for delivering high-quality experiences to end-users.
Financial services institutions, including banks, insurance companies, and fintech startups, rely on AWS for its security, compliance capabilities, and services for data analytics, fraud detection, and running core banking systems.

Compute services (EC2, Lambda)
At the heart of any cloud platform are its compute services, which provide the processing power needed to run applications. AWS offers a range of compute options to suit different needs. Perhaps the most well-known is Amazon Elastic Compute Cloud (EC2). EC2 allows users to rent virtual servers, known as instances, in the cloud. These instances can run various operating systems and can be configured with different amounts of CPU, memory, storage, and networking capacity. EC2 provides a highly flexible and scalable way to deploy applications, from simple web servers to complex, distributed systems. Users have granular control over their instances and can easily scale their compute capacity up or down as needed.
Another key compute service is AWS Lambda. Lambda is a serverless compute service, meaning developers can run their code without provisioning or managing servers. With Lambda, you upload your code, and Lambda takes care of everything required to run and scale your code with high availability. You only pay for the compute time you consume, and there is no charge when your code is not running. Lambda is ideal for event-driven applications, such as processing data from S3 buckets, responding to HTTP requests via Amazon API Gateway, or processing streaming data.
For those who find these concepts a bit abstract, let's try an "Explain Like I'm 5" (ELI5) approach. Imagine EC2 is like renting a specific computer in the cloud. You can choose how powerful it is (like a fast gaming computer or a basic one for homework), what software it runs, and you can use it for as long as you need. You're in charge of managing it. Now, imagine Lambda is like having a magic helper who only appears when you have a specific small job to do, like sorting your toys. You tell the helper the instructions (your code), and they do the job quickly and disappear. You don't have to worry about where the helper lives or making sure they have enough energy; they just do the work when needed.

Storage solutions (S3, EBS)
Data storage is another critical component of cloud computing, and AWS provides a variety of storage services tailored to different requirements. One of the most foundational and widely used is Amazon Simple Storage Service (S3). S3 is an object storage service that offers industry-leading scalability, data availability, security, and performance. It allows you to store and retrieve any amount of data, at any time, from anywhere on the web. S3 is commonly used for a wide range of use cases, including website hosting, data backup and archiving, application data storage, and big data analytics.
For persistent block storage for use with Amazon EC2 instances, AWS offers Amazon Elastic Block Store (EBS). EBS provides block-level storage volumes that you can attach to your EC2 instances. These volumes behave like raw, unformatted block devices, similar to a physical hard drive. You can create file systems on EBS volumes, run databases, or use them in any other way you would use a block device. EBS volumes are persistent, meaning their data remains even if you stop or terminate the EC2 instance they are attached to (unless configured otherwise). EBS offers different volume types optimized for various performance and cost requirements.
ELI5 for storage: Think of Amazon S3 like a giant digital closet where you can store all sorts of files – photos, videos, documents, anything! You can put as much stuff as you want in there, and it's kept very safe. You can access your files from anywhere with an internet connection. Amazon EBS is more like a personal hard drive that you plug directly into your rented cloud computer (your EC2 instance). It’s where that specific computer keeps its operating system and the files it's actively working on. It's fast and directly connected to that one computer.

Database management systems
AWS offers a comprehensive suite of managed database services, catering to various data models and application needs. This allows developers to focus on application development rather than the operational overhead of database management, such as patching, backups, and scaling. Amazon Relational Database Service (RDS) makes it easy to set up, operate, and scale a relational database in the cloud. It supports several popular database engines, including MySQL, PostgreSQL, MariaDB, Oracle, and SQL Server. RDS automates time-consuming administration tasks, allowing users to focus on their applications.
For NoSQL database needs, Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. It's a fully managed, multi-region, multi-active, durable database with built-in security, backup and restore, and in-memory caching for internet-scale applications. Another important database service is Amazon Aurora, a MySQL and PostgreSQL-compatible relational database built for the cloud, which claims to provide the performance and availability of commercial databases at a fraction of the cost. AWS also provides specialized database services for data warehousing (Amazon Redshift), graph databases (Amazon Neptune), and time-series data (Amazon Timestream), among others.
ELI5 for databases: Imagine you have a huge collection of organized information, like a giant address book or a library catalog. Amazon RDS helps you manage traditional address books (relational databases) where information is neatly arranged in tables with rows and columns. It takes care of keeping the address book software updated and backed up. Amazon DynamoDB is like a super-fast, flexible filing cabinet where you can store lots of different types of information (like notes, lists, or pictures) and find them very quickly, even if you have millions of them. It's great for apps that need to access data rapidly.

Networking fundamentals (VPC, Route 53)
Networking is a fundamental aspect of any IT infrastructure, and AWS provides robust services to build and manage virtual networks in the cloud. Amazon Virtual Private Cloud (VPC) lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define. You have complete control over your virtual networking environment, including selection of your own IP address ranges, creation of subnets, and configuration of route tables and network gateways. You can easily customize the network configuration for your Amazon VPC. For example, you can create a public-facing subnet for your web servers that has access to the internet, and place your backend systems, such as databases or application servers, in a private-facing subnet with no internet access.
Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service. It is designed to give developers and businesses an extremely reliable and cost-effective way to route end users to internet applications by translating names like `www.example.com` into the numeric IP addresses like `192.0.2.1` that computers use to connect to each other. Route 53 also offers domain name registration, health checking for resources, and traffic management capabilities that can route traffic based on various criteria, such as latency, geography, or weighted round robin.
ELI5 for networking: Imagine Amazon VPC is like building your own private, fenced-off area within a giant playground (the AWS cloud). Inside your private area, you can decide where to put your different toys (your cloud resources like computers and databases) and who gets to come in and out. You can even create separate sections within your area. Amazon Route 53 is like the internet's address book. When you type a website name into your browser, Route 53 helps your computer find the correct digital address (IP address) for that website so you can connect to it. It also helps manage your website names.
