Serverless computing is a cloud-based execution model that enables applications to be hosted as a service, without the need to maintain a server.
The service provider maintains the resource allocation on the server and the user is billed based on the actual usage. The focus shifts to the core application that one is creating and the infrastructure is handled solely by the service provider. Serverless computing is also known as Function as a Service (FaaS).
In this guide, we’ll take a close look at what Serverless PHP means, its main features and pros vs cons to provide you with a better understanding of this approach towards cloud computing.
Specifically, we’ll look at the concept of serverless computing, its use cases and scope, advantages and drawbacks, a simple implementation of serverless PHP with Bref and the status of serverless PHP on the big three (Amazon, Microsoft, and Google).

Traditionally, you needed the hardware for a server to set up an application on the Internet. The server machine (or machines) would be physically connected to the Internet for someone to access your application. Server maintenance was an expensive affair.
Next, the evolution of hosting services allowed webmasters to purchases hosting space — each server could hold multiple applications. This lowered costs.
With the rise of cloud computing, economies of scale further reduced costs, as you could rent a tiny amount of space on a large, remote server farm. In fact, serverless computing allows you to only pay for the services you use. When not in use, you are practically not utilizing any space or resource on the cloud.
Serverless computing simplifies the software development process: it allows an organization focused solely on development without worrying about deployment, server upkeep, and scaling.
Serverless PHP: The Basics
To deploy a serverless PHP application, you should first explore the concept of serverless computing. While the term serverless first appeared in this article on the future of software development from 2012 on ReadWrite, it gained popularity with the launch of AWS Lambda in 2014.
In this section, let us focus on a few key concepts related to serverless computing, and try to answer a common question that surrounds this technology: is it really server-“less”?
Features of Serverless PHP
Deployment is an easy task without managing the server. You simply upload your code to the server and the rest is taken care of by the vendor. Serverless technology allows you to have language-agnostic functions, interacting with each other.
For instance, if you have a messaging application, the login module may be coded in one language and the function that updates your status may
