In the previous lesson, we learned that cloud computing lets us run applications without managing physical servers. Now it's time to know about the basics of Amazon Web Services (AWS).
AWS Global Infrastructure
AWS is built on a powerful global infrastructure. It's what keeps your applications running reliably. No matter where your users are, they get fast performance. Low latency and high availability are built in, right from the start.
Regions and Availability Zones
- Regions are geographic areas like US East (N. Virginia) or Asia Pacific (Mumbai).
- Each Region has multiple Availability Zones (AZs), which are isolated data centers. Each data center has independent power, networking, and cooling.
We can reduce the failure by using multiple regions and zones.
Edge Locations, Local Zones, and Wavelength
AWS also has locations to make your applications faster for users:
- Edge Locations: Cache content near users.
- Local Zones: Bring some AWS services closer to big cities.
- Wavelength Zones: Connect to 5G networks for very low-latency apps.
AWS Outposts
If you need AWS services on your own premises, Outposts extend AWS infrastructure to your data center for a hybrid cloud experience.
Shared Responsibility Model
Security in the cloud isn’t automatic. AWS uses the Shared Responsibility Model to clarify who handles which aspects of security.
- AWS handles "Security of the Cloud": Protects the physical data centers, servers, networking, and foundational services.
- You handle "Security in the Cloud": Responsible for applications, data, identity, access controls, encryption, and network configurations.
It’s a partnership: AWS provides the secure infrastructure, and you build on it responsibly.
AWS Well-Architected Framework
AWS has a guide called the Well-Architected Framework. It is a guideline to build strong, reliable systems. It’s based on six points. According to their official docs, here are the points:
- Operational Excellence – Monitor and improve systems continuously.
- Security – Protect data, accounts, and workloads.
- Reliability – Recover quickly from failures.
- Performance Efficiency – Use resources smartly and scale efficiently.
- Cost Optimization – Avoid waste and maximize value.
- Sustainability – Reduce environmental impact.
Following these pillars helps you build secure, efficient, and reliable applications.
Conclusion
So, in this post, we've learned about AWS global infrastructures, the shared responsibility model of AWS, and the well-architected framework by AWS.
