1 - What is Amazon Web Services (AWS)?
AWS is a leading cloud services provider offering a wide range of on demand computing resources and services, including computing power, storage, and databases, delivered over the internet. It allows businesses to scale and grow without the need for investing in hardware infrastructure.
2) Explain Elastic Compute Cloud (EC2) in AWS.
EC2 is a web service that provides resizable compute capacity in the cloud. Users can launch virtual servers, known as instances, with various configurations to meet their specific needs. EC2 offers flexibility, scalability, and cost effectiveness by allowing users to pay only for the computing resources they consume.
3) What is Amazon Simple Storage Service (S3)?
Amazon S3 is a scalable object storage service designed to store and retrieve any amount of data from anywhere on the web. It provides high availability, durability, and security for data storage needs. S3 is commonly used for data backup, archiving, and serving static assets for websites.
4) What are the different types of instances available in EC2?
EC2 provides various instance types optimized for different workloads, such as General Purpose, Compute Optimized, Memory Optimized, Storage Optimized, and Accelerated Computing. Each instance type has specific configurations to meet the performance requirements of different applications.
5) Explain the concept of Virtual Private Cloud (VPC) in AWS.
A VPC allows users to create isolated virtual networks within the AWS cloud. It provides control over network settings, such as IP addresses, subnets, route tables, and security groups, enabling users to build a secure and customized network environment for their resources.
6) How does AWS Identity and Access Management (IAM) work?
IAM is a service that helps manage user access and permissions to AWS resources securely. Users can create and control individual IAM users, groups, and roles with granular permissions. IAM allows organizations to enforce security best practices by providing least privilege access to resources.
7) What is Amazon Relational Database Service (RDS)?
RDS is a managed database service that simplifies the setup, operation, and scaling of relational databases in the cloud. Users can choose from various database engines, such as MySQL, PostgreSQL, Oracle, and SQL Server, and benefit from automated backups, monitoring, and maintenance tasks.
8) How does AWS Lambda function?
AWS Lambda is a serverless computing service that allows users to run code without provisioning or managing servers. Users can upload their code to Lambda and define triggers to execute the code in response to events, such as changes in S3 buckets, API calls, or scheduled tasks.
9) What is Amazon Elastic Container Service (ECS)?
ECS is a container management service that allows users to run and scale containerized applications on the AWS cloud. It integrates with Docker containers and provides features like task scheduling, load balancing, and service discovery to simplify container orchestration.
10) How does Amazon CloudWatch help in monitoring AWS resources?
CloudWatch is a monitoring and observability service that collects and tracks metrics, logs, and events from AWS resources in real time. It enables users to set alarms, create dashboards, and analyze performance data to ensure the efficient operation of their cloud infrastructure.
