Master-Slave - PHP

The Master-Slave pattern involves a primary database (Master) handling all write operations, while one or more read-only replicas (Slaves) serve read requests. This improves performance by distributing the read load and provides read scalability. The PHP code demonstrates a simple abstraction for interacting with a …

Publish-Subscribe - PHP

The Publish-Subscribe (Pub/Sub) pattern decouples message senders (publishers) from message receivers (subscribers). Publishers don’t know who their listeners are, and subscribers only know that messages of a certain type are published, not who publishes them. This promotes flexibility and scalability.

Blackboard - PHP

The Blackboard pattern is a centralized data repository (the “blackboard”) coupled with a set of independent, specialized agents that operate on that data. Agents react to changes on the blackboard, contributing knowledge or transforming the data until a solution is reached. This decouples the data and the processing …

Pipes and Filters - PHP

The Pipes and Filters pattern structures a program as a series of processing steps (filters) connected by channels (pipes) that pass data from one filter to the next. Each filter has a specific responsibility and operates on the data independently. This promotes reusability, maintainability, and simplifies complex …

Cluster-based Architecture - PHP

The Cluster-based Architecture pattern distributes application components across multiple servers (a “cluster”) to improve performance, reliability, and scalability. Each server within the cluster typically runs the same code and shares the workload. Requests are routed to available servers using a load …

Shared-Nothing - PHP

The Shared-Nothing pattern is an architecture where each worker (or node) in a distributed system has its own private memory and storage, and communication happens primarily through network calls. No shared resources like databases or file systems are directly accessed by multiple workers. This enhances scalability and …

Message Broker - PHP

The Message Broker pattern decouples application components by enabling them to communicate through an intermediary message store. Components don’t directly call each other; instead, they publish messages to the broker, and other components subscribe to specific message types to receive and process them. This …

Space-Based Architecture - PHP

The Space-Based Architecture pattern organizes code into loosely coupled, independent “spaces” or modules, each responsible for a specific aspect of the application. These spaces communicate through well-defined interfaces, minimizing dependencies and promoting modularity. This implementation uses PHP …

Event-Driven Architecture - PHP

The Event-Driven Architecture (EDA) decouples software components by allowing them to react to events without knowing who created them. Components (event producers) emit events, and other components (event consumers) subscribe to specific events they’re interested in. This promotes flexibility and scalability. …

SOA - PHP

The Service-Oriented Architecture (SOA) pattern structures an application as a collection of loosely coupled, interoperable services. Each service encapsulates a distinct business function and exposes a well-defined interface, typically via network calls. This promotes reusability, maintainability, and scalability. …
