What is AWS?

Last updated on 

Amazon Web Services (AWS) is a comprehensive and widely used cloud computing platform provided by Amazon. It offers a broad set of infrastructure services, including computing power, storage options, networking, databases, machine learning, analytics, and more. AWS allows businesses and individuals to access a variety of computing resources on a pay-as-you-go basis without the need to invest in and maintain physical hardware.

Here is a technical breakdown of key components and services within AWS:

  1. Compute Services:
    • EC2 (Elastic Compute Cloud): Virtual servers in the cloud that can be configured with different computing capacities and operating systems.
    • Lambda: Serverless compute service where you can run code without provisioning or managing servers.
  2. Storage Services:
    • S3 (Simple Storage Service): Scalable object storage that allows you to store and retrieve any amount of data.
    • EBS (Elastic Block Store): Persistent block-level storage volumes for use with EC2 instances.
  3. Database Services:
    • RDS (Relational Database Service): Managed relational databases supporting multiple database engines like MySQL, PostgreSQL, Oracle, and Microsoft SQL Server.
    • DynamoDB: Fully managed NoSQL database service for high-performance applications.
  4. Networking:
    • VPC (Virtual Private Cloud): A logically isolated section of the AWS Cloud where you can launch resources in a virtual network.
    • Route 53: AWS's scalable domain name system (DNS) web service.
  5. Content Delivery:
    • CloudFront: Content Delivery Network (CDN) that securely delivers data, videos, applications, and APIs to customers globally.
  6. Analytics and Big Data:
    • S3 (Data Lakes): Used for building big data lakes by storing and analyzing vast amounts of data.
    • EMR (Elastic MapReduce): A cloud-based big data platform used for processing and analyzing large data sets.
  7. Machine Learning and AI:
    • SageMaker: Fully managed service to build, train, and deploy machine learning models.
    • Rekognition: Deep learning-based image and video analysis service.
  8. Security and Identity:
    • IAM (Identity and Access Management): Manages access to AWS services and resources securely.
    • Cognito: Provides authentication, authorization, and user management for web and mobile apps.
  9. Management and Monitoring:
    • CloudWatch: Monitoring and observability service for resources and applications on AWS.
    • CloudTrail: Records AWS API calls for your account and delivers log files to your S3 bucket.
  10. Deployment and Automation:
    • Elastic Beanstalk: Platform as a Service (PaaS) for deploying and managing applications.
    • OpsWorks: Manages applications and servers using Chef or Puppet for configuration management.
