An Overview of Domain-Driven Design

By Rob Allen

Domain-Driven Design (DDD) is an approach to software development that focuses on understanding and dealing with complex business needs. We will explore the strengths of DDD, including its approach to structuring software around an abstract model of a business problem and creating a ‘ubiquitous language’ for communication among developers and domain experts. We’ll look at the strategic and tactical aspects of DDD and show that the central benefit of this approach is improved collaboration, better understanding of business processes, and ultimately, better and more flexible software. by Rob Allen

Serverless PHP With Bref, Part Two

By Rob Allen

In part one of this series, I introduced serverless applications and looked at how Bref makes it easy to develop and deploy serverless PHP functions to AWS Lambda with a simple hello world function. Serverless functions don’t live in a vacuum and tend to integrate with other services, let’s turn our attention to what a complete serverless application looks like by building a static website hosted on S3 which is updated using a PHP Lambda function. by Rob Allen

Serverless PHP With Bref, Part One

By Rob Allen

In recent years, a different way to build applications has arisen called serverless computing. This term is not a good name; I’m reminded of the adage that there are two hard problems in programming: naming things, cache invalidation, and off-by-one errors. Serverless computing as a name implies no servers, but there are servers—you don’t think about them though. A better way to think about it is that the servers and the management of them are abstracted away and the provider manages the allocation of resources, not the application architect. In this article, I’m going to walk through how to use Lambda with PHP to execute a function.
