As you explore AWS, consider how its diverse range of tools can support your unique project requirements and growth ambitions.
I. AWS Fundamentals & Core Concepts
1. What is Amazon Web Services (AWS)?
Amazon Web Services (AWS) is a secure cloud services platform, offering compute power, database storage, content delivery, and other functionality to help businesses scale and grow. It provides a broad set of global cloud-based products including compute, storage, databases, analytics, networking, mobile, developer tools, management tools, IoT, security, and enterprise applications.
2. What is Cloud Computing?
Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like AWS.
3. What are the main benefits of using AWS?
Key benefits include:
- Cost-Effectiveness: Pay only for what you use, reducing upfront capital expenditure.
- Scalability & Elasticity: Easily scale resources up or down based on demand.
- Agility & Speed: Rapidly deploy applications and iterate faster.
- Global Reach: Deploy applications in multiple regions around the world.
- Security: Benefit from a highly secure infrastructure.
- Reliability: High availability and fault tolerance.
- Innovation: Access to a wide range of advanced services (AI/ML, IoT, etc.).
4. What is IaaS, PaaS, and SaaS in the context of AWS?
- IaaS (Infrastructure as a Service): Provides basic building blocks for cloud IT. AWS examples: EC2 (compute), S3 (storage), VPC (networking). You manage the OS and applications.
- PaaS (Platform as a Service): Removes the need to manage underlying infrastructure (hardware and OS), allowing you to focus on deployment and management of applications. AWS examples: Elastic Beanstalk, RDS (for managed databases).
- SaaS (Software as a Service): Provides a completed product run and managed by the service provider. AWS offers some SaaS (e.g., Amazon WorkMail), and many SaaS providers build their solutions on AWS.
5. What are AWS Regions and Availability Zones (AZs)?
Regions are separate geographic areas where AWS clusters data centers. Each Region is completely independent. Availability Zones (AZs) are isolated locations within a Region, consisting of one or more discrete data centers with redundant power, networking, and connectivity. Deploying applications across multiple AZs provides high availability and fault tolerance.
6. What is the AWS Free Tier?
The AWS Free Tier allows new customers to use certain AWS services for free up to specified limits for 12 months from sign-up, and some services offer an always-free tier. It’s a great way to get hands-on experience with AWS.
7. How does AWS pricing work?
AWS primarily uses a pay-as-you-go model. You pay only for the individual services you need, for as long as you use them, without long-term contracts or complex licensing. Some services offer Reserved Instances or Savings Plans for significant discounts in exchange for commitment. Managing these costs effectively can be complex, and services from companies like CloudRank can help with cloud financial management.
8. What is the AWS Shared Responsibility Model?
This model defines security responsibilities. AWS is responsible for the “security *of* the cloud” (infrastructure, hardware, software, networking, and facilities that run AWS services). The customer is responsible for “security *in* the cloud” (customer data, platform, applications, identity & access management, OS, network & firewall configuration).
9. How do I sign up for an AWS account?
Visit the AWS website (aws.amazon.com) and click on “Create an AWS Account.” You’ll need to provide contact information, payment details (for services beyond the Free Tier), and verify your identity.
10. What is the AWS Management Console?
The AWS Management Console is a web-based interface for accessing and managing your AWS services. You can launch instances, configure storage, manage databases, set up networking, and much more.
II. Compute Services
11. What is Amazon EC2 (Elastic Compute Cloud)?
Amazon EC2 provides scalable virtual servers (known as instances) in the cloud. You can choose from various instance types optimized for different workloads (general purpose, compute-optimized, memory-optimized, storage-optimized, GPU-instances).
12. What are EC2 Instance Types?
EC2 offers a wide variety of instance types with different combinations of CPU, memory, storage, and networking capacity. Examples include t-series (burstable, general purpose), m-series (general purpose), c-series (compute-optimized), r-series (memory-optimized), and p/g-series (GPU instances).
13. What is an AMI (Amazon Machine Image)?
An AMI is a pre-configured template for your EC2 instances. It includes the operating system, application server, and applications. AWS provides many AMIs, and you can also create your own.
14. What are EC2 Purchasing Options (On-Demand, Spot, Reserved)?
- On-Demand Instances: Pay by the hour or second (depending on OS) with no long-term commitment. Ideal for unpredictable workloads.
- Spot Instances: Bid on spare EC2 computing capacity for up to 90% off On-Demand prices. Suitable for fault-tolerant, flexible workloads.
- Reserved Instances (RIs) & Savings Plans: Provide significant discounts (up to 72%) compared to On-Demand pricing in exchange for a 1-year or 3-year commitment.
15. What is Amazon EC2 Auto Scaling?
EC2 Auto Scaling helps you maintain application availability and allows you to automatically add or remove EC2 instances according to conditions you define, such as CPU utilization or network traffic.
16. What is AWS Lambda?
AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers. You pay only for the compute time you consume – there’s no charge when your code isn’t running. It’s ideal for event-driven applications.
17. What does “serverless” mean in AWS?
Serverless means you can build and run applications and services without thinking about servers. AWS handles the underlying infrastructure, scaling, and maintenance, allowing developers to focus on code. Lambda is a prime example.
18. What is Amazon Lightsail?
Amazon Lightsail is designed to be the easiest way to launch and manage a virtual private server (VPS) with AWS. It includes everything you need to jumpstart your project – a virtual machine, SSD-based storage, data transfer, DNS management, and a static IP – for a low, predictable monthly price.
19. What is AWS Elastic Beanstalk?

Amazon 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 range, creation of subnets, and configuration of route tables and network gateways.
42. What are Subnets in a VPC?
A subnet is a range of IP addresses in your VPC. You can launch AWS resources, such as EC2 instances, into a specified subnet. Use public subnets for resources that must be connected to the internet, and private subnets for resources that won’t be connected to the internet.
43. What are Security Groups in AWS?
A Security Group acts as a virtual firewall for your EC2 instances to control inbound and outbound traffic. They are stateful, meaning if you allow inbound traffic on a port, outbound traffic for that connection is automatically allowed.
44. What are Network Access Control Lists (NACLs)?
NACLs are an optional layer of security for your VPC that acts as a firewall for controlling traffic in and out of one or more subnets. They are stateless, meaning you must explicitly define rules for both inbound and outbound traffic.
45. What is the difference between Security Groups and NACLs?
- Security Groups: Operate at the instance level, stateful, allow rules only.
- NACLs: Operate at the subnet level, stateless, allow and deny rules.
