📌 Event-Driven Architecture Design Summary

Event-Driven Architecture Design is a way of building software systems where different parts communicate by sending and receiving messages called events. When something important happens, such as a user action or a system change, an event is created and sent out. Other parts of the system listen for these events and respond to them as needed. This approach allows systems to be more flexible, scalable, and easier to update, since components do not need to know the details about each other.

🙋🏻‍♂️ Explain Event-Driven Architecture Design Simply

Imagine a school assembly where the headteacher rings a bell whenever something important happens, like a fire drill or lunch break. Everyone listens for the bell and reacts in their own way without needing to talk to the headteacher directly. In Event-Driven Architecture, the bell is like an event, and each part of the system responds when it hears an event it cares about.

📅 How Can it be used?

You can use Event-Driven Architecture to build an online shop where orders, payments, and delivery updates are handled by separate, loosely connected services.

🗺️ Real World Examples

In a ride-hailing app, when a rider requests a trip, an event is published. Independent services for matching drivers, calculating fare, and sending notifications all listen for this event and act accordingly, making the system responsive and easy to scale.

A financial trading platform uses Event-Driven Architecture to react to market changes in real time. Price updates and trade executions are sent as events, which are processed by different services for risk analysis, portfolio updates, and alerting users.

✅ FAQ

Event-driven architecture design is a way of building software where different parts talk to each other by sending messages called events. When something important happens, like a button being clicked or a file being updated, an event is sent out. Other parts of the system listen for these events and react as needed. This approach helps make systems more adaptable and easier to change over time.

People choose event-driven architecture because it allows different parts of a system to work independently. This means you can add new features or update parts without having to change everything else. It also helps systems handle lots of activity at once, making them more flexible and able to grow as needed.

Because each part of an event-driven system listens for events instead of relying on direct connections, you can update or replace parts without affecting the rest. This makes it much easier to improve or add new features over time, as changes can be made with less risk of breaking other parts of the system.

Batch Prompt Processing Engines

Batch prompt processing engines are software systems that handle multiple prompts or requests at once, rather than one at a time. These engines are designed to efficiently process large groups of prompts for AI models, reducing waiting times and improving resource use. They are commonly used when many users or tasks need to be handled simultaneously, such as in customer support chatbots or automated content generation.

LLM Acceptable Use Criteria

LLM Acceptable Use Criteria are guidelines that set out how large language models can be used responsibly and safely. These criteria help prevent misuse, such as generating harmful, illegal, or misleading content. They are often put in place by organisations or service providers to ensure that users follow ethical and legal standards when working with LLMs.

Function as a Service

Function as a Service, or FaaS, is a cloud computing model where you can run small pieces of code, called functions, without managing servers or infrastructure. You simply write your code and upload it to a cloud provider, which takes care of running it whenever it is needed. This allows you to focus on your application logic while the cloud provider automatically handles scaling and resource management.

Phishing Simulation

Phishing simulation is a security exercise where organisations send fake phishing emails to their own staff to test how well employees can spot and avoid suspicious messages. The main goal is to identify weaknesses in staff awareness and train them to recognise real phishing attacks. This helps reduce the risk that employees will click on harmful links or share confidential information with attackers.

AI for Customs

AI for Customs refers to the use of artificial intelligence technologies to help customs authorities manage the flow of goods across borders. AI can help identify risks, speed up inspections, and automate paperwork. By analysing large amounts of data, AI can support customs officers in making faster and more accurate decisions about shipments.
