Hello tech enthusiasts! Today, we're stepping into the realm of AWS interview questions – a hot topic that many of you requested! Ready to sharpen those interview skills? Let's dive in and tackle some common AWS questions together! 💡
Interview Questions Galore! 🌐
1. Name 5 AWS Services and their Use Cases 🛠️
EC2 (Elastic Compute Cloud): Scalable virtual servers for running applications.
S3 (Simple Storage Service): Object storage for storing and retrieving any amount of data.
RDS (Relational Database Service): Managed relational databases in the cloud.
Lambda: Serverless computing for executing code without managing servers.
IAM (Identity and Access Management): Securely manage access to AWS services.
2. Tools for Sending Logs to the Cloud ☁️
Common tools include CloudWatch, CloudTrail, and third-party solutions like ELK Stack.
3. IAM Roles – Creation and Management 🤖
IAM Roles are created and managed through the AWS Management Console or using the AWS Command Line Interface (CLI).
4. Upgrading/Downgrading a System with Zero Downtime ⬆️⬇️
Leverage strategies like Blue-Green deployments, canary releases, or rolling deployments to ensure seamless transitions.
5. Infrastructure as Code (IaC) and Its Usage 🏗️
IaC is the practice of managing and provisioning infrastructure through code. Tools like AWS CloudFormation or Terraform are used to automate infrastructure setup.
6. Load Balancer and Scenarios ⚖️
Load balancers distribute incoming network traffic across multiple servers. Scenarios include:
Application Load Balancer (ALB): Ideal for HTTP/HTTPS traffic.
Network Load Balancer (NLB): Best for TCP/UDP traffic.
Classic Load Balancer: Legacy, suitable for basic setups.
7. CloudFormation and Its Purpose 🌪️
AWS CloudFormation is used for provisioning and managing AWS infrastructure as code. It allows you to define and deploy resources in a safe, predictable manner.
8. AWS CloudFormation vs. AWS Elastic Beanstalk 🤔
CloudFormation: Infrastructure provisioning, customizable.
Elastic Beanstalk: Fully managed platform, simplified deployments.
9. Security Attacks in the Cloud and Minimization 🚨
Common attacks include DDoS, data breaches, and unauthorized access. Minimize by using proper encryption, access controls, and monitoring.
10. Recovering EC2 Instance Without Key 🔑
Yes, you can recover by stopping the instance, detaching the root volume, attaching it to another instance, modifying the authorized_keys file, and reattaching it.
11. Gateway – Definition 🔗
A gateway is a network node that connects two different networks, facilitating communication between them.
12. Differences Between Amazon RDS, DynamoDB, and Redshift 🔄
RDS: Managed relational databases.
DynamoDB: NoSQL, fully managed.
Redshift: Fully managed data warehouse for analytics.
13. Hosting a Website on S3 – Yes or No? And Why? 🌐
Yes, because S3 offers scalable, low-latency storage with built-in features like versioning and website hosting.
