We can save time by using the existing feature for throttling API in case the Client calls more than the quota limit.Let me explain some key features of AWS API Gateway: Looking at the diagram above, it doesn’t make sense because we could call the “App Server” directly through the Load Balance, skipping the API Gateway. Diagram from API Gateway with Nginx behind WAF The entry point is known as Front Proxy or Reverse Proxy and is responsible for forwarding all requests to each API using rules based on DNS. Why is it expensive? Most of the companies that provide the service to protect your Web Application also provide CDN (Content Delivery Network), which has a price model to charge you by each application (DNS).įor scenarios where you have many APIs spread across different servers, it may be worth centralizing the access through a single entry point. Integrating and putting your API in front of a WAF (Web Application Firewall) is pretty expensive today. Save MoneyĬompanies must always protect your Web Site and APIs, but that comes with a cost.
In our scenario, the AWS API Gateway is a private resource where only requests from inside the same VPC are allowed. Security: If you have sensitive data, you should be careful about exposing your Web Application to the internet. Simplify Network Configuration: Build a single entry point to access all private resources instead of creating and managing multiple security layers for several servers and their configuration individually. Why use Nginx as reverse with AWS API Gateway Where behind the API Gateway is running some EC2 instances with the APIs.
Explain and present a solution using WAF and how you can organize your architecture to save money and time managing multiple Web Applications.Let’s review one architecture using AWS API Gateway, and Nginx protected with a WAF.
