Cloud computing has transformed the way businesses build, deploy, and manage applications. Instead of investing in expensive physical servers and infrastructure, organizations can now access computing resources over the internet whenever they need them. One of the leading cloud platforms powering this transformation is Amazon Web Services (AWS).

If you’re wondering “What is AWS?”, this guide will explain everything you need to know from the basics of cloud computing to AWS services, benefits, pricing, career opportunities, and how to start learning AWS in 2026.

What is AWS?

Amazon Web Services (AWS) is a cloud computing platform provided by Amazon that offers more than 200 fully featured cloud services. It enables individuals, startups, enterprises, and governments to build, host, and manage applications without maintaining their own physical servers.

Instead of purchasing hardware, AWS allows you to rent computing resources such as:

• Virtual servers
• Cloud storage
• Databases
• Networking services
• Artificial Intelligence (AI) tools
• Machine Learning (ML) services
• Security solutions
• Analytics platforms

AWS follows a pay-as-you-go pricing model, meaning you only pay for the services you use.

What is Cloud Computing?

Before understanding AWS, it’s important to know what cloud computing means.

Cloud computing is the delivery of IT resources including servers, storage, databases, networking, software, and analytics over the internet.

Instead of buying and maintaining expensive hardware, businesses rent these resources from cloud providers like AWS.

Traditional IT Infrastructure

• Buy physical servers
• Maintain data centers
• Handle hardware failures
• Large upfront investment
• Limited scalability

Cloud Computing with AWS

• No physical hardware to purchase
• Instant deployment
• Scale resources in minutes
• High availability
• Pay only for what you use

History of AWS

AWS was officially launched by Amazon in 2006 with the goal of making cloud infrastructure available to developers and businesses worldwide.

Initially, AWS offered just a few services, such as:

• Amazon S3
• Amazon EC2

Today, AWS has grown into the world’s largest cloud platform, serving millions of customers across industries including healthcare, finance, education, retail, entertainment, and government.

How Does AWS Work?

AWS operates through a global network of secure data centers.

When you launch a service such as an Amazon EC2 virtual machine, AWS provisions the necessary hardware in one of its data centers and makes it available to you within minutes.

The process is simple:

• Sign in to the AWS Management Console.
• Choose the service you want to use.
• Configure the required settings.
• Launch the resource.
• Pay only for the resources consumed.

This eliminates the need to purchase and maintain physical servers.

AWS Global Infrastructure

AWS has one of the largest cloud infrastructures in the world.

Its infrastructure consists of:

• Regions – Separate geographic locations around the world.
• Availability Zones (AZs) – Isolated data centers within a region for high availability.
• Edge Locations – Global locations used to deliver content quickly through services like Amazon CloudFront.

This global network ensures:

• Low latency
• High availability
• Disaster recovery
• Improved performance
