Interviews Questions - (Aws)
AWS Fundamentals
What is AWS (Amazon Web Services)?
- AWS is a comprehensive cloud computing platform offered by Amazon.
- It provides a wide range of services
for computing, storage, networking, databases, and more.
What are the key benefits of using AWS?
- Scalability: Easily scale resources up or down based on demand.
- Cost-effectiveness: Pay-as-you-go pricing, eliminating upfront costs.
- Reliability: Highly reliable and available infrastructure with multiple availability zones.
- Flexibility: Wide range of services to choose from, allowing you to build any type of application.
- Security: Robust security features, including encryption, access control, and threat detection.
Explain the concept of IaaS, PaaS, and SaaS.
- IaaS (Infrastructure as a Service): Provides fundamental computing resources like servers, storage, and networking (e.g., EC2, EBS).
- PaaS (Platform as a Service): Provides a platform for developing, running, and managing applications without worrying about the underlying infrastructure
(e.g., Elastic Beanstalk, Lambda). - SaaS (Software as a Service): Provides applications accessible over the internet (e.g., Salesforce, Amazon WorkDocs).
What are the different AWS regions and availability zones?
- Regions: Geographical locations where AWS data centers are located.
- Availability Zones: Separate, isolated locations within a region, providing high availability.
What is the AWS Management Console?
- A web-based interface for managing AWS services.
Compute Services
What is Amazon EC2 (Elastic Compute Cloud)?
- Provides virtual machines (VMs) in the cloud.
What is Amazon ECS (Elastic Container Service)?
- A container orchestration service for deploying, managing, and scaling containerized applications.
What is AWS Lambda?
- A serverless compute service that runs code in response to events.
What is AWS Fargate?
- A serverless compute engine for containers that runs containers without managing servers.
Storage Services
What is Amazon S3 (Simple Storage Service)?
- Object storage for storing and retrieving any amount of data.
What is Amazon EBS (Elastic Block Store)?
- Block-level storage volumes designed for use with EC2 instances.
What is Amazon Glacier?
- Low-cost, durable, and highly scalable cloud storage for long-term archiving.
Database Services
What is Amazon RDS (Relational Database Service)?
- Provides managed relational databases, such as MySQL, PostgreSQL, and SQL Server.
What is Amazon DynamoDB?
- A NoSQL database service that provides fast and scalable data storage for any application.
What is Amazon Redshift?
- A fast, scalable, and cost-effective data warehousing service.
Networking
What is Amazon VPC (Virtual Private Cloud)?
- Allows you to create an isolated and private network within the AWS cloud.
What is Amazon Route 53?
- A scalable and reliable DNS service.
What is Amazon CloudFront?
- A content delivery network (CDN) for delivering content with high speed and low latency.
Security
What is AWS IAM (Identity and Access Management)?
- Provides granular control over who can access AWS resources.
What is AWS KMS (Key Management Service)?
- A managed service for creating and controlling cryptographic keys.
What is AWS Security Groups?
- Act as virtual firewalls for EC2 instances, controlling inbound and outbound traffic.
Other Services
What is AWS Elastic Beanstalk?
- An easy-to-use service for deploying and scaling web applications and services.
What is AWS Step Functions?
- A visual workflow service that helps you build and run distributed applications.
What is AWS IoT?
- A platform for connecting, managing, and interacting with billions of devices.
