AWS Cloud Overview - Regions & AZ

I learn about the AWS Cloud, its history, market leadership, global infrastructure, and service scope.
Goal: To provide foundational knowledge of AWS services and how they can be applied in real-world projects.

Key takeaways​

  • History of AWS: Launched in 2002 for internal use, AWS began offering services to the public in 2004, with significant services like SQS, S3 and EC2 released in 2006.

  • Versatility: AWS supports a variety of applications across industries, including data storage, website hosting, and big data analytics.
  • Global Infrastructure: AWS has multiple regions worldwide, including Europe, Asia, and South America, with each region comprising several availability zones (AZs).
  • Availability Zones: These are isolated data centers designed to prevent cascading failures during disasters, enhancing reliability and availability.
  • Choosing Regions: Factors like compliance requirements, latency, service availability, and pricing should guide the choice of AWS regions.
  • Points of Presence: Also known as edge locations, these help improve content delivery by minimizing latency for end-users.
  • Service Scope: The lecture introduces the distinction between region-scope services and global AWS services, paving the way for deeper course exploration.
    • Global services: Identity and Access Management (IAM), Route 53 (DNS service), CloudFront (CDN), Web Application Firewall (WAF).
    • Region-scoped services: Amazon EC2 (Infrastructure as a Service), Elastic Beanstalk (Platform as a Service), Lambda (Function as a Service), Rekognition (Software as a Service).
