AWS (Amazon Web Services) is a cloud computing platform provided by Amazon. It offers a wide range of services such as computing power, storage, databases, and networking over the internet. AWS enables companies to easily deploy and scale applications without needing to invest in physical infrastructure.
The core services offered by AWS include compute services (EC2, Lambda), storage services (S3, EBS), database services (RDS, DynamoDB), networking services (VPC, Route 53), analytics services (Amazon Redshift, Athena), AI and machine learning services (SageMaker, Rekognition), and management tools (CloudFormation, CloudWatch).
EC2 (Elastic Compute Cloud) is a virtual server that allows users to run applications while S3 (Simple Storage Service) is a storage service for storing and retrieving data. Essentially, EC2 provides computing power while S3 offers cloud storage.

ExploreAn AMI (Amazon Machine Image) in AWS is a template that contains a software configuration, operating system, applications, and data necessary to launch an EC2 instance. It provides a consistent environment for developing, testing, and running applications in the cloud.
You can secure your data in AWS by implementing strong access controls, encrypting your data at rest and in transit, regularly monitoring for any unauthorized access or unusual activity, implementing multi-factor authentication, and regularly backing up your data to prevent data loss.
IAM roles are meant to be assumed by AWS services or resources, allowing them to perform actions on your behalf. IAM users, on the other hand, represent individual users within your AWS account, allowing them to securely interact with AWS resources using their own credentials.
In AWS, you can monitor resources and applications using AWS CloudWatch, which provides performance metrics, log files, and alarms to track the health and performance of your applications. You can also enable AWS CloudTrail to monitor API activity and track changes made to your AWS resources.
AWS Lambda is a serverless computing service provided by Amazon Web Services. It allows users to run code without provisioning or managing servers, only paying for the compute time consumed. The service automatically scales based on the incoming requests and supports a variety of programming languages.
A Virtual Private Cloud (VPC) is a virtual network in AWS that allows users to control and customize their network configuration. It provides isolation and security for resources within the VPC, enabling users to launch and run AWS resources securely within their own virtual network.
CloudFormation is important in AWS because it allows users to easily and efficiently create and manage a collection of AWS resources through code, known as templates. This helps automate the deployment process, reduce human error, enforce best practices, and maintain consistency across environments.
AWS handles scalability and elasticity by allowing users to easily scale resources up or down based on demand. This is done through services like Auto Scaling, which automatically adjusts the number of EC2 instances based on predefined conditions, ensuring optimal performance and cost efficiency.
The different types of storage options available in AWS include Amazon S3 for scalable object storage, Amazon EBS for persistent block storage, Amazon EFS for shared file storage, Amazon Glacier for low-cost archival storage, and Amazon Storage Gateway for hybrid cloud storage integration.
AWS Auto Scaling is a feature that automatically adjusts the number of instances in a cluster based on demand. It helps maintain optimal performance by adding or removing instances as needed, ensuring efficient resource utilization and cost-effectiveness. This allows for seamless scaling without manual intervention.
AWS manages security and compliance through a combination of security features, encryption methods, and compliance certifications. This includes services like AWS Identity and Access Management (IAM), AWS Key Management Service (KMS), and adherence to industry standards and regulations. Regular audits and monitoring help ensure a secure environment.
AWS CloudWatch is a monitoring and logging service provided by Amazon Web Services. It is used to collect and track operational data in real-time from AWS resources such as EC2 instances, Lambda functions, and RDS databases. CloudWatch helps users monitor performance, troubleshoot issues, and set up alarms for notifications.
AWS provides benefits for disaster recovery by offering scalable and flexible cloud infrastructure, automated backup and recovery processes, high availability of services across regions, cost-effectiveness with pay-as-you-go pricing, and the ability to quickly spin up resources in the event of a disaster.
AWS Elastic Beanstalk is a Platform as a Service (PaaS) offering by Amazon Web Services that simplifies the deployment and management of web applications. It allows developers to upload their application code and automatically handles the deployment, scaling, and monitoring of the infrastructure required to run the application.
AWS handles data encryption by offering various encryption services and features such as AWS Key Management Service (KMS), AWS CloudHSM, and AWS Certificate Manager. Customers can encrypt data at rest, in transit, and manage encryption keys securely to ensure data confidentiality and integrity.
AWS CloudTrail is a service that logs API activity across AWS services. It helps in auditing by providing a detailed history of API requests made within an AWS account, including details such as the identity of the requester, the time of the request, and the actions taken.
AWS RDS (Relational Database Service) is a managed service that simplifies the process of setting up, operating, and scaling relational databases in the cloud. It supports popular database engines like MySQL, PostgreSQL, and SQL Server, offering features such as automated backups, monitoring, and security patches.
