Que 7-What is Amazon EC2 and what are its key features?

Ans- Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud. It allows you to launch virtual machines (VMs), known as instances, with a variety of configurations. Some key features of EC2 include the ability to scale resources up or down as needed, pay for only what you use, and select from a variety of instance types and operating systems.


Que 8-What is Amazon VPC and what are its components?

Ans- Amazon Virtual Private Cloud (VPC) allows you to create a private, isolated section of the AWS cloud where you can launch AWS resources in a virtual network that you define. It has the following components:

Subnet: A subnet is a range of IP addresses in your VPC. You can launch Amazon Elastic Compute Cloud (EC2) instances in a subnet.

Route Table: A route table contains a set of rules, called routes, that are used to determine where network traffic is directed.

Internet Gateway: An internet gateway is a horizontally scaleable, redundant, and highly available VPC component that allows communication between instances in your VPC and the Internet.

Virtual Private Gateway: A virtual private gateway is the VPC-side endpoint for your VPN connection.

RDS automatically handles tasks such as provisioning, backups, software patching, and monitoring. Some key features of RDS include automatic backups, automatic software patching, and the ability to scale storage and compute resources.


Que 10-What is Amazon CloudFront and what are its use cases?

Ans- Amazon CloudFront is a content delivery network (CDN) that speeds up the distribution of static and dynamic web content, such as HTML, CSS, JavaScript, and images. It uses a global network of edge locations to cache and serve content, reducing the load on origin servers and improving the performance for end users. Some common use cases for CloudFront include delivering content for websites, mobile apps, and streaming media.


Que 11- What are the important factors to consider when choosing an Amazon Elastic Block Store (EBS) volume type?

Ans- The factors to consider when choosing an EBS volume type are IOPS, Throughput, Latency, and cost. Some workloads require high IOPS, some require high throughput and low latency, and some require both. EBS provides different volume types for different needs.


Que 12- What is Amazon Elastic Load Balancer (ELB) and how does it work?

Ans- Amazon Elastic Load Balancer (ELB) is a service that automatically distributes incoming web traffic across multiple Amazon Elastic Compute Cloud (EC2) instances. ELB automatically routes incoming traffic to the healthy instances and automatically re-routes traffic away from instances that become unhealthy. It also provides security features like SSL/TLS termination, and can be integrated with other services like AWS WAF.


Que 13-What is Amazon Elastic Beanstalk and what are its use cases?

Ans- Amazon Elastic Beanstalk is a fully managed service that makes it easy to deploy, run, and scale web applications and services. It supports a variety of programming languages and runtime environments, and can automatically handle tasks such as capacity provisioning, load balancing, and automatic scaling. Elastic Beanstalk is commonly used for hosting web applications, web services, and batch processes.


Que 14- What is Amazon SQS and what are its key features?

Ans- Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. SQS allows you to send, store, and receive messages between software components at any volume, without losing messages or requiring other services to be available. Some key features of SQS include the ability to send and receive messages, support for multiple protocols, and integration with other AWS services.


Que 15- How does Amazon SNS work and what are its use cases?

Ans- Amazon Simple Notification Service (SNS) is a fully managed messaging service for both system-to-system and app-to-person communication. SNS allows you to send messages to multiple subscribers, including email, HTTP/S, Lambda, SQS, and mobile push. SNS can be used for sending notifications, fan-out, SMS, and triggering AWS Lambda functions.


Que 16- What is Amazon Glue and what are its use cases?

Ans- Amazon Glue is a fully managed extract, transform, and load (ETL) service that makes it easy to move data between data stores. Glue automatically discovers data and stores the associated metadata, allowing you to start analyzing your data without manually coding the extraction, transformation, or loading process. Glue can be used for ETL jobs, Data Catalog, and Data lake integration.


Que 17- What is Amazon Kinesis and what are its use cases?

Ans- Amazon Kinesis is a fully managed service for real-time processing of streaming data at any scale. Kinesis allows you to collect, process, and analyze real-time streaming data, such as video, audio, application logs, website clickstreams, and IoT telemetry data for applications like real-time analytics, video and image analysis, and IoT device data analysis.


Que 18- What is Amazon CloudWatch and what are its key features?

IAM enables you to create and manage AWS users and groups, and use permissions to allow and deny their access to AWS resources. Some key features of IAM include the ability to manage users, groups, and permissions, multi factor authentication (MFA) support, and integration with other AWS services.


Que 20- What is Amazon S3 security and how do you secure S3 Buckets?

Ans- Amazon S3 security allows you to control access to your data in S3 Buckets through the use of access control lists (ACLs) and bucket policies. You can use IAM policies to manage access to S3 Buckets, and also use S3 bucket policies to further restrict access to your S3 Buckets. Additionally, S3 provides features like encryption, versioning and access logs to secure the data in the bucket.


Que 21- How does Amazon VPC security work and what are its key features?

Ans- Amazon Virtual Private Cloud (VPC) security allows you to control access to your VPC resources through the use of security groups and network access control lists (ACLs). Security groups act as a firewall for associated Amazon Elastic Compute Cloud (EC2) instances, while network ACLs act as a firewall for all traffic in and out of your subnets. Additionally, VPC also provides features like VPC endpoint, VPN, and Direct Connect to secure the network.


Que 22- What is Amazon KMS and how does it work?

Ans- Amazon Key Management Service (KMS) is a managed service that makes it easy for you to create and control the encryption keys used to encrypt your data.

Some key features of CloudTrail include the ability to track user activity, support for multiple accounts and regions, and integration with other AWS services.


Que 24- How does Amazon WAF work and what are its use cases?

Ans- Amazon Web Application Firewall (WAF) is a service that makes it easy to protect web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources. WAF uses rules and rule groups, which are collections of rules, to identify and block malicious web requests. WAF can be used to protect web applications from SQL injection, cross-site scripting (XSS), and other common web-based attacks.


Que 25- How can you secure your AWS environment ?

Ans-There are several ways to secure an AWS environment, including:

  1. Use IAM (Identity and Access Management) to control access to AWS resources and services.
  2. Enable multi-factor authentication for IAM users.
  3. Use security groups and network ACLs to control inbound and outbound traffic to your instances.
  4. Use VPC (Virtual Private Cloud) to create a logically-isolated section of the AWS cloud where you can launch resources in a virtual network that you define.
  5. Use encryption to protect sensitive data both at rest and in transit.
  6. Regularly review and monitor security-related events in CloudTrail and AWS Config.
  7. Use AWS Config and AWS Config rules to ensure that resources are configured in compliance with security best practices.
  8. Use AWS Security Hub to aggregate and prioritize security findings from across AWS services, third-party security solutions, and your own security data sources.
