📌 Event-Driven Architecture Summary

Event-Driven Architecture is a software design pattern where different parts of a system communicate by sending and responding to events. Instead of constantly checking for changes, components react when something specific happens, like a user clicking a button or a payment being made. This approach can help systems become more flexible and able to handle many tasks at once.

🙋🏻‍♂️ Explain Event-Driven Architecture Simply

Imagine a school bell ringing to signal class changes. Instead of each teacher checking the clock, they just wait for the bell and act when it rings. In event-driven architecture, software parts wait for their own bell, or event, and respond only when it happens. This makes things run more smoothly and efficiently.

📅 How Can it be used?

You could use event-driven architecture to let different microservices in an online store react instantly to orders, stock changes, and customer actions.

🗺️ Real World Examples

In online banking, when a customer makes a payment, an event is triggered. This event notifies other parts of the system to update the account balance, send a confirmation message, and log the transaction, all without manual intervention.

A ride-sharing app uses event-driven architecture so that when a driver accepts a ride, an event is sent to update the passenger, adjust the driver’s status, and start the trip tracking, keeping everything in sync in real time.

✅ FAQ

Event-driven architecture is a way of designing software so that different parts of a system talk to each other by sending messages when something happens, like a button being clicked or a payment going through. Instead of constantly checking for updates, each part simply reacts when it needs to, making systems more flexible and efficient.

Developers use event-driven architecture because it helps systems handle lots of things at the same time without getting bogged down. By reacting only when specific events occur, it makes it easier to add new features and makes the system more responsive to users.

Yes, event-driven architecture can help apps feel faster and more responsive. Because the different parts of the system only act when needed, there is less waiting around and fewer unnecessary checks, which can speed up how quickly things happen for the user.

AI-Based Knowledge Suggestions

AI-based knowledge suggestions use artificial intelligence to recommend helpful information, resources, or actions to users based on what they are doing or searching for. These systems analyse user behaviour, context, and previous interactions to present relevant content or guidance. The aim is to make finding the right information faster and easier, reducing the effort needed to search manually.

IT Operations Analytics

IT Operations Analytics is the practice of collecting and analysing data from IT systems to improve their performance and reliability. It uses data from servers, networks, applications and other IT components to spot issues, predict failures and optimise operations. This approach helps IT teams make informed decisions and fix problems before they affect users.

AI Risk Management

AI risk management is the process of identifying, assessing, and addressing potential problems that could arise when using artificial intelligence systems. It helps ensure that AI technologies are safe, fair, reliable, and do not cause unintended harm. This involves setting rules, monitoring systems, and making adjustments to reduce risks and improve outcomes.

Data Flow Optimization

Data flow optimisation is the process of improving how data moves and is processed within a system, such as a computer program, network, or business workflow. The main goal is to reduce delays, avoid unnecessary work, and use resources efficiently. By streamlining the path that data takes, organisations can make their systems faster and more reliable.

Secure Data Aggregation

Secure data aggregation is a method used to combine data from multiple sources while keeping the individual data private and protected. It ensures that sensitive information is not exposed during the collection and processing stages. This approach is important in situations where data privacy is required, such as healthcare or finance, as it allows useful insights to be extracted without revealing personal details.
