It has revolutionized the way businesses handle infrastructure by making computing utility accessible like electricity. AWS offers over 200 cloud services that help enterprises build, deploy, and scale applications globally.

Question 2

When was AWS founded and by whom?

Accepted Answer

AWS was launched in 2006 by the Amazon team led by Andy Jassy, who pioneered the cloud computing revolution while working within Amazon. The platform was developed under the vision of CEO Jeff Bezos to make computing resources as accessible and utility-like as electricity. Andy Jassy later became the CEO of Amazon and continued leading AWS as a key business division.

Question 3

AWS's original and continuing mission is to make computing utility like electricity—accessible, affordable, and available to anyone who needs it. This vision drives the platform's commitment to democratizing cloud technology and removing barriers to entry for businesses of all sizes. AWS aims to empower organizations by providing scalable, reliable infrastructure without requiring massive upfront capital investments.

Question 4

What are the main AWS services?

Accepted Answer

AWS offers over 200 cloud services, with some of the most popular being EC2 (virtual computing), S3 (object storage), Lambda (serverless computing), RDS (managed databases), ECS (container orchestration), and EKS (Kubernetes management). These services span compute, storage, networking, databases, analytics, machine learning, and more. Each service is designed to be independently scalable and can be combined to build complex applications.

Question 5

What is EC2 and what is it used for?

Accepted Answer

EC2 (Elastic Compute Cloud) is AWS's foundational virtual computing service that allows users to launch resizable computing instances in the cloud. It provides complete control over computing resources with flexible configuration options for memory, processing power, and storage. EC2 is used for web servers, application hosting, batch processing, and any workload requiring on-demand computing capacity.

Question 6

What is Amazon S3 and why is it important?

Accepted Answer

Amazon S3 (Simple Storage Service) is one of AWS's flagship services that provides scalable object storage accessible from anywhere on the internet. It's designed for durability, availability, and performance, making it ideal for storing everything from website assets to data backups and archives. S3 powers millions of businesses worldwide and is foundational to the AWS ecosystem.

Question 7

What is AWS Lambda and how does serverless computing work?

Accepted Answer

AWS Lambda, introduced in 2014, is a serverless computing service that lets you run code without managing servers or infrastructure. You simply upload your code, and Lambda automatically scales to handle the workload while charging only for the compute time you use. This innovation transformed application development by eliminating server maintenance overhead and enabling event-driven architectures.

Question 8

How does AWS pricing work?

Accepted Answer

AWS uses a pay-as-you-go pricing model where you only pay for the services and resources you actually use, with no upfront commitments required. Pricing varies by service and region, with options for on-demand, reserved instances, and spot pricing to optimize costs. This flexible approach allows startups to get started cheaply while enterprises can scale without massive capital expenditures.

Question 9

What makes AWS the market leader in cloud computing?

Accepted Answer

AWS dominates the cloud market with 32%+ market share and over $90 billion in annual revenue, achieved through continuous innovation and service expansion. The platform benefits from being first-to-market as the pioneering cloud provider, offering the broadest range of services (200+), and maintaining the most global infrastructure with multiple regions and availability zones. AWS's reliability, scale, and ecosystem of partners make it the trusted choice for enterprises worldwide.

Question 10

What industries and use cases benefit from AWS?

Accepted Answer

AWS serves diverse industries including e-commerce, financial services, healthcare, media, gaming, startups, and government. Organizations use AWS for web applications, mobile backends, big data analytics, machine learning, content delivery, disaster recovery, and digital transformation. The platform's flexibility and scalability make it suitable for use cases ranging from small internal tools to mission-critical enterprise applications handling millions of users.

Question 11

How do I get started with AWS?

Accepted Answer

Getting started with AWS is straightforward: create an AWS account, choose the services you need (many offer a free tier for new users), and begin deploying your applications. AWS provides comprehensive documentation, tutorials, and certification programs to help users learn the platform. You can start with a single service like S3 or EC2 and gradually expand your usage as your needs grow.

Question 12

What are AWS regions and availability zones?

Accepted Answer

AWS operates multiple global regions (geographic areas with independent infrastructure) and availability zones within each region to provide redundancy and low-latency access. This distributed architecture ensures high availability, disaster recovery capabilities, and compliance with data residency requirements. Users can deploy applications close to their customers for better performance and reliability.

Question 13

How does AWS ensure security and reliability?

Accepted Answer

AWS employs multiple layers of security including encryption, access controls, network isolation, and continuous threat monitoring across all services. The platform maintains high availability through redundant infrastructure, automated failover, and backup systems. AWS's reliability is backed by Service Level Agreements (SLAs) and has proven track record serving mission-critical applications for enterprises globally.

Question 14

What is the relationship between AWS and Amazon?

Accepted Answer

AWS is Amazon's cloud computing division and one of the company's most profitable business units, generating over $90 billion in annual revenue. While AWS operates as a separate business unit within Amazon, it benefits from Amazon's infrastructure investments, technical expertise, and global presence. AWS demonstrates that cloud technology can be as essential and utility-like as the electricity Amazon's retail business depends on.

Question 15

How has AWS evolved since 2006?

Accepted Answer

Since launching with EC2 and S3 in 2006, AWS has expanded to offer 200+ services with major milestones including the introduction of Lambda serverless computing in 2014 and continued innovation in container management (ECS, EKS), databases, and artificial intelligence. The platform has grown from an internal Amazon tool to the world's leading cloud provider with 32%+ market share. Today, AWS continues advancing cloud technology with new services and capabilities released regularly.
