As some of you may know, traffic within AWS is free, and traffic going outside of AWS has a small cost. We had never restricted outgoing traffic because it makes sense for our customers to access their database from their local environments.

Excerpts from The Elements of Programming Style. The source of this compilation is unknown.

The Elements of Programming Style

The following rules of programming style are excerpted from the book "The Elements of Programming Style" by Kernighan and Plauger, published by McGraw Hill. Here is quote from the book: "To paraphrase an observation in The Elements of Style by Strunk and White, the rules of programming style, like those of English, are sometimes broken, even by the best writers. When a rule is broken, however, you will usually find in the program some compensating merit, attained at the cost of the violation. Unless you are certain of doing as well, you will probably do best to follow the rules."
