1. What is AWS?
Answer: AWS stands for Amazon Web Services. It’s a cloud platform that offers a variety of services like computing power, storage options, and networking capabilities to help individuals and businesses build and manage their applications more efficiently.
2. What is EC2?
Answer: EC2, or Elastic Compute Cloud, is a web service that provides resizable computing capacity in the cloud. It allows you to quickly scale up or down the number of virtual servers you need to run your applications.
3. What is S3?
Answer: S3, or Simple Storage Service, is an object storage service that allows you to store and retrieve data from anywhere on the web. It’s highly scalable, reliable, and offers low-latency access to your data.
4. What is scalability in AWS?
Answer: Scalability in AWS refers to the ability to increase or decrease resources as needed to handle changing workload demands. AWS services like EC2 and Auto Scaling allow you to automatically adjust resources to maintain performance and optimize costs.
5. What is the difference between IAM and resource-based policies?
Answer: IAM, or Identity and Access Management, is used to manage users, groups, and permissions within your AWS account. Resource-based policies, on the other hand, are attached directly to AWS resources like S3 buckets or SQS queues to control access to those resources.
6. What is a VPC?
Answer: VPC, or Virtual Private Cloud, is a virtual network dedicated to your AWS account. It allows you to define your own network topology, including IP address ranges, subnets, and route tables, and control inbound and outbound traffic.
7. What is AWS Lambda?
Answer: AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers. You simply upload your code, and Lambda takes care of everything required to run and scale your code with high availability.
8. What is CloudFormation?
Answer: CloudFormation is a service that allows you to create and manage AWS infrastructure as code using templates. With CloudFormation, you can define your infrastructure in a JSON or YAML file, and AWS will provision and configure the resources automatically.
9. How does AWS handle security?
Answer: AWS employs a shared responsibility model for security, where AWS is responsible for the security of the cloud infrastructure, and customers are responsible for securing their data and applications within AWS. AWS provides a wide range of security features and services like IAM, VPC, and encryption to help customers meet their security requirements.
10. What is the AWS Well-Architected Framework?
Answer: The AWS Well-Architected Framework provides best practices and guidance for designing and operating secure, high-performing, resilient, and efficient infrastructure in the cloud. It consists of five pillars: operational excellence, security, reliability, performance efficiency, and cost optimization. By following the Well-Architected Framework, customers can build and maintain systems that meet their business needs and scale with their growth.
