VPC Architecture connects all VPC components together to have production ready customized network topology in AWS cloud. 

This Architecture connecting some basic VPC components to deploy EC2 instances into Public and Private Subnets. VPC Architecture can be designed in multiple ways based on the project scope and requirement. However this VPC architecture shown simple flow to understand the VPC Layer.

Limitations:

• VPC cannot span multiple regions, all the resources that you are create in to a single VPC must be from same region.
• VPC can have multiple subnets that are associated to the multiple availability zones.
• One VPC can be associated with only one internet gateway.
• One internet Gateway cannot be attached with more than one VPC.
• One subnet cannot be associated for multiple availability zones; however, a single availability zone can have multiple subnets.
• One subnet must be associated with only one route table; However, a single route table can be associated with multiple subnets.
• AWS ensures that there will be a default VPC for every region, however if you do not prefer to deploy resources into default VPC you can always create a customized VPC with your own networking topology requirements.
