AWS Global Infrastructure
- The terms of importance
- Region:
- Geographical location identified by AWS to build Datacenters
- This is collection of Availability Zones
- Every Region has a code
<continent>-<direction>-<number> - Examples:
mumbai = ap-south-1, hyderabad ap-south-2 - Refer Here for the complete list of regions
- Availability Zone:
- This is a site within a Region
- In each Region you will multiple AZ’s
- Distance between AZ’s in a region will be around 30-60 kms
- Every AZ will have names
<region>[a-z] - Mumbai AZ’s
ap-south-1a, ap-south-1b...
- Local Zone
- This is a Site built in different parts of the world
- This local zone can be added to some marked Regions
- Refer Here for local zones in AWS
- Local Zone has parent region
- Edge Location:
- This acts as Point of presence locations
- Wavelength Zone:
- This was designed for 5G networks

AWS Networking Major Components
-
Major Components of AWS Networking are
- VPC
- Subnet
- Internet Gateway
- Route Table
- Network Interface
- Elastic IP
- Security Group
- Network ACL
-
VPC (Virtual Private Cloud)
- is a virtual network which we can create in AWS
- belongs to a region
- We can create the private network of size required by using CIDR
- In every region AWS ensures you have a default VPC.
- Subnet:
- AWS Subnet is subnet of VPC
- belongs to AZ
- We can create resources and connect to subnet
- size is expressed in CIDR
- Internet Gateway:
- This gives dual connectivity i.e. vpc can access internet and internet can access resources in vpc using public ip addressing
- If you want only one way connectivity then AWS has Egress only Internet Gateway
- Route Table:
- This will act as a Router
- When we create a vpc, aws will create a default route table
- By default AWS will allow connections between all the subnets
Lets create a vpc in AWS
- Naviagate to vpc and create a sample network
- AWS gives VPC ID
- Now lets add subnets
- If we want to view only our vpc resources
Terms
- Egress: Outgoing
- Ingress: incoming
