As discussed above, the web, application and database servers are placed in separate tiers and only the web servers are exposed to the incoming internet traffic. In case, one availability zone is not accessible or has failures, the other availability zone can still be used to serve the traffic. One of the design principles for cost optimization is to use managed services to reduce cost of ownership i.e. AWS holds the highest 33% market share of cloud computing. The next step is to provision the EC2 instances within the public and private subnets. AWS Serverless Web Applications Architecture As mentioned above, we can find more about the development of serverless web applications by reflecting on the AWS serverless application architecture. It is an important part of this architecture to separate the user interface layer with the business logic layer so that the servers are not overloaded by handling different type of requests at a time.
