As your app scales, it often evolves from a monolith into a set of microservices — each responsible for a specific business function. That’s great for scaling teams and codebases, but it introduces a big problem:
How do you give clients a single, seamless entry point while keeping your microservices loosely coupled?
The answer is an API Gateway.

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.
The following steps assume you've got a set-up like mine, where:
| <?php | |
| $basePrices = [ | |
| "6,00 € /l" => ['price' => '6,00', 'volume' => '1', 'unit' => 'l'], | |

| "1.15 € / 100 gr" => ['price' => '1.15', 'volume' => '100', 'unit' => 'gr'], | |
| "2.33 € / 1 kg" => ['price' => '2.33', 'volume' => '1', 'unit' => 'kg'], | |
