One of our customers that handles sensitive customer data needed a secure cloud infrastructure for their web apps and databases. We implemented a NAT Gateway in a VPC to allow instances in private subnets to access the internet for updates and API calls while blocking inbound traffic. This solution provides internet access to private instances without exposing them directly to the public internet, enhancing security. Here’s what we did: This diagram illustrates a typical VPC setup divided into three main sections: VPC, public subnet, and private subnet. First we have the outer green box, the VPC, which isolates the resources within it from other networks. Users access the web server through the public internet using a static IP address assigned via 1:1 NAT. The web server processes the requests and, if necessary, communicates with the database server. The web server communicates with the database server through the Router Server.…
