What are the key components of AWS?
EC2 (Elastic Compute Cloud)
S3 (Simple Storage Service)
VPC (Virtual Private Cloud)
RDS (Relational Database Service)
IAM (Identity and Access Management)
AWS Lambda
Amazon Route 53
CloudFront
Auto Scaling
Elastic Load Balancer (ELB)
What is the difference between S3, EBS, and EFS?
S3 is object storage for files, EBS is block storage for EC2 instances, and EFS is a file system for EC2 instances.
What is the difference between a region and an availability zone?
A region is a physical location in the world that contains multiple availability zones. Availability zones are isolated data centers within a region that have their own power, networking, and cooling infrastructure.
What is the difference between EC2 and Lambda?
EC2 is a virtual server that allows you to run applications on the cloud. Lambda is a serverless computing service that allows you to run code without provisioning or managing servers.
Explain the concept of Elastic Load Balancing and Auto Scaling.
Elastic Load Balancing distributes incoming traffic across multiple EC2 instances to ensure high availability and fault tolerance. Auto Scaling automatically adjusts the number of EC2 instances in a group based on the load or specified conditions.
What is the purpose of Amazon VPC?
Amazon VPC enables you to create a virtual network in the AWS cloud, providing complete control over network configuration, including IP addressing, subnets, routing, and security.
What is the difference between RDS and DynamoDB?
RDS is a managed relational database service, while DynamoDB is a managed NoSQL database service. RDS supports multiple database engines like MySQL, PostgreSQL, Oracle, and SQL Server, whereas DynamoDB is a key-value and document database.
What is IAM, and what are IAM roles?
IAM (Identity and Access Management) is a service that helps you control access to AWS resources. IAM roles are a secure way to grant permissions to entities that you trust. Instead of using access keys, you can assign roles to AWS resources.
Explain the different storage classes in Amazon S3.
Amazon S3 offers multiple storage classes, including Standard, Intelligent-Tiering, Standard-IA (Infrequent Access), One Zone-IA, Glacier, and Glacier Deep Archive. Each storage class has different availability, durability, performance, and pricing characteristics.
What is CloudFront, and how does it work?
CloudFront is a content delivery network (CDN) service that speeds up the distribution of your static and dynamic web content, such as images, videos, and HTML files. CloudFront caches content at edge locations worldwide, reducing latency and improving user experience.
