It has been a pretty long day as I was struggling to get a Laravel application to return SSL or HTTPS connections. I was put in this situation because the SysOp team of my company placed the laravel app behind a loadbalancer accepting SSL connections but converting these connection to HTTP.
It seems trivial but it did mess with the laravel application that relies on the incoming protocol to define login/logout url pages for instances
After messing up and discovering TrustProxies I found an easy solution with
Here is my solution , open the file app/Providers/AppServiceProvider.php
And add the following line URL::forceScheme('https');
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\URL;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*
* @return void
*/
public function register()
{
//
}
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot()
{
URL::forceScheme('https');
}
}

Nowadays, IT departments have been jam-packed with a lot of nonsense and therefore a lot of Jira tickets, if you see what I mean. Here is a way to quickly assess the necessity of a task or a project to be executed. It is important to raise these questions during preliminary meetings. Once the project is launched, it will be difficult to backpedal according to my experience. Also great find in this tweet great ideas on how to tackle this question https://twitter.com/sebdedeyne/status/1271370141683638273
Is it going to fix something ?
Can we afford to break what’s already working ?
Do we really need to make that change ?
Is it going to improve performance ?
Here are the most critical questions :
How will this make users/customer live better ?
How is it going to make our developers lives better ?
Although these questions above may seem rational and logical, they can easily and will be easily swept away by some great irresponsible political bluffer developer/manager mentioning the security of a system or application. The word is dropped : Security. The winning argument, the selling point to any individual and to any of our dear IT companies, FEAR.
Although most of our infrastructure are covered with firewalls, proxies, CDN and heavy monitoring systems – I have seen Fear win the argument even if the chance of its occurring was inexistent
For starter with AWS, Serverless Framework CLI is a must. Build your entire infrastructure in seconds !
What does AWS mean ? Amazon Web Service.
What does AWS provide ? provides on-demand cloud computing platforms and APIs to individuals, companies, and governments, on a metered pay-as-you-go basis such as hosting web server
What is Serverless framework CLI ? . A single configuration file allows you to list your functions and define the endpoints that they’re subscribed to. It provides structure, automation and best practices out-of-the-box, allowing you to focus on building sophisticated, event-driven, serverless architectures, comprised of functions and events. The Serverless Framework CLI is the simplest way to develop infinitely scalable, pay-per-execution serverless applications.
Big plus is the serverless.yaml creating the above structure in seconds
I built an architecture SQS, DLQ, SNS and Lambda with serverless and it is fantastic for deployment and quick development. This framework made the whole development experience smooth
What is SQS ? Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications.
What is DLQ ? You can now set a dead-letter queue (DLQ) to an Amazon Simple Notification Service (SNS) subscription to capture undeliverable messages. Amazon SNS DLQs make your application more resilient and durable by storing messages in case your subscription endpoint becomes unreachable.
What is SNS ? Amazon SNS is a fully managed pub/sub messaging service. You can use Amazon SNS topics to decouple message publishers and subscribers, and simultaneously distribute messages to multiple endpoints, such as Amazon SQS queues, AWS Lambda functions, HTTP endpoints, email addresses, and mobile devices (SMS text messages and mobile push notifications).
What is Lambda ? AWS Lambda is a serverless compute service that runs your code in response to events and automatically manages the underlying compute resources for you.
