Amazon Web Services (AWS) offers PaaS (Platform as a service), IaaS (infrastructure as a service), serverless computing, and much more. In AWS Architecture security different security groups allow. The Internet Gateway service allows the EC2 instances in public subnets to access the internet and NAT Gateways allows EC2 instances in private subnets to access the internet. The following AWS Architecture diagram, which is created using EdrawMax, shows how data and information are shared across two AWS regions. These AWS cloud content have respective databases that are linked via different functions. The diagram shows how a latency-based routing takes effect when the request is generated from different users. In order to increase the elasticity and decrease the server load time, elastic load balancers are also used between these two AWS cloud services.
