Though micro-services are often designed around separately hosted and separate API endpoint-based integrations, there are many other ways to implement a micro-service. The key, as indicated by the name, is that the code therein is small and performs a single task or workflow. Developers in monolithic structures will often write this code in Actions or Jobs. However, the code still needs to be removed from the main codebase and as such, poor code choices can creep into these Actions or Jobs over time. 

You can, as an alternative, enlist the help of a framework like Laravel Zero built by Nuno Maduro. Let's first make it clear: Laravel Zero is not new. It's over four years old and was designed to provide a straightforward, beginner-friendly environment for creating powerful command-line applications. Laravel Zero takes the Laravel experience and shrinks it down for a more focused use while retaining the essential ingredients of a Laravel-style application. 

Reduced Overhead:

Laravel Zero removes the unnecessary components that do not serve a purpose in console application development. Without web-related elements like HTTP routing, cookie sessions, and views, Laravel Zero becomes a leaner and more efficient tool that reduces overhead when used in console environments. 

Simplicity:

It is beautifully simple. Its command handlers are written in just one file, simplifying its structure and making it easy to locate and track your applications. 

Speed and Performance:

It utilizes a minimalist architecture – and no, this isn't about fancy design trends. By removing the need for a full-blown Laravel application booting, Laravel Zero favours speed and performance. This stripped-back tool allows your task to run faster and use less memory. This can be incredibly handy when it comes to handling significant processes.

Advanced Task Scheduling:

Laravel Zero comes with the usual built-in task scheduler that performs automatic periodic command execution, pulled straight out of Laravel's core. So, it enables command scheduling, which is an essential functionality in automation and periodic tasks. 

Robustness:

While pre-designed to be lean and lightweight, Laravel Zero can still be scaled up if the need arises, meaning it's more than capable of handling robust and complex applications.

Flexibility and Customizability:

Having stripped away a lot of the features, Laravel Zero also allows developers the freedom to customize the framework to their liking or to suit the needs of their project. Developers can easily re-include any of Laravel's features in Laravel Zero if they find they need them.

Queue Integration:

Laravel Zero has also integrated the excellent 'queue' system. This means you can run a Laravel Zero app as nothing more than an elegant worker bee on any given server you're running. Letting it be aware of any queue requests it's responsible for.

Built-in Testing Functions:

Whether using PEST or PHPUnit, writing and running tests is unbelievably easy. It's like writing legit Unit-based tests.

Automatic Security Updates:

Laravel Zero receives automatic security updates similar to Laravel. This ensures that your console applications built with Laravel Zero are always secure from potential vulnerabilities.

Laravel Zero has indeed carved out its niche in the Laravel ecosystem. I highly recommend it for those who want to explore the command-line interface (CLI) development scope, with its simplicity, user-friendly nature, in-built features, and minimalist architecture.
