AWS Global Infrastructure: Regions and Availability Zones Explained 🗺️
AWS Cloud Technical Essentials
What is AWS Global Infrastructure? 🤔
AWS Global Infrastructure is like the backbone of every cloud application. It's where all the data centers and connections live. The big parts you need to know about are AWS Regions and Availability Zones (AZs).
AWS Regions 📍
These are like different neighborhoods around the world where AWS keeps its data centers. Each one has a name based on its location. The data doesn't automatically move between them unless you say so.
For example:
us-east-1: Northern Virginia (US East)
ap-northeast-1: Tokyo (Asia Pacific Northeast)
Choosing the Right AWS Region 💡
When you're picking a Region, you need to think about a few things:
Latency: You want to pick a Region close to your users so they don't have to wait forever for things to load.
Price: The cost can vary depending on where you're hosting your stuff.
Service Availability: Some services might not be available everywhere.
Data Compliance: Depending on the rules, your data might need to stay in a specific place.
AWS Availability Zones 🏘️
Inside each Region, there are these groups called Availability Zones. They're like little communities of data centers with their own power and connections. They're set up so that if one goes down, the others can keep going without any problems.
For example:
us-east-1a: Northern Virginia (us-east-1)
sa-east-1b: São Paulo (sa-east-1)
AWS Services Scope 🎯
AWS services can be used in different ways:
Region-scoped services: These work across the whole Region automatically.
AZ-specific services: You have to pick which Availability Zone you want to use and manage things yourself.
Maintaining Resiliency 🪧
To make sure your stuff stays up and running:
Use Region-scoped services whenever you can.
Spread your work across multiple Availability Zones. That way, if something goes wrong, your stuff will still be safe.
