📌 Software-Defined Networking (SDN) Summary

Software-Defined Networking (SDN) is a method of managing computer networks that separates the system controlling where data goes from the devices that actually move the data. This makes it easier for network administrators to manage, adjust, and automate network behaviour using software rather than manual configuration of hardware. SDN allows updates and changes to be made quickly without needing to physically interact with network devices.

🙋🏻‍♂️ Explain Software-Defined Networking (SDN) Simply

Imagine your school has many classrooms, and instead of each teacher making their own rules, there is a central principal who can instantly update rules for all classrooms from their office. SDN works in a similar way by letting one central controller manage and change the whole network through software, making it faster and easier to keep everything running smoothly.

📅 How Can it be used?

You can use SDN to automatically reroute traffic in a company network during busy periods to prevent slowdowns.

🗺️ Real World Examples

A large university uses SDN to manage its campus-wide Wi-Fi. When a big event causes network congestion in one area, the SDN controller can quickly adjust the flow of data to keep internet speeds stable for students and staff.

A cloud service provider uses SDN to quickly set up secure, isolated networks for new customers, allowing them to deploy new services in minutes without manual hardware changes.

✅ FAQ

Software-Defined Networking, or SDN, is a way to manage computer networks using software rather than relying on physical hardware. It allows network managers to make changes quickly and easily, without having to physically adjust each device. This makes networks more flexible and easier to maintain, which is especially helpful as networks grow and change.

SDN lets network administrators control the flow of data through a central piece of software. Instead of going to each piece of equipment to make changes, they can update settings from one place, saving time and reducing the chance of mistakes. This also helps when new devices are added or when the network needs to be updated to handle more traffic.

Yes, SDN can help with network security because it allows changes and updates to be made quickly in response to threats. If a problem is detected, administrators can use SDN to adjust security rules or block suspicious traffic right away, all without needing to physically access the network hardware.

Service Blueprinting

Service blueprinting is a method used to visually map out all the steps involved in delivering a service. It shows how customers interact with a service, what happens behind the scenes, and how the different parts work together. This helps organisations understand and improve the customer experience by identifying gaps or problems in the process.

Secure DevOps Pipelines

Secure DevOps Pipelines refer to the integration of security practices and tools into the automated processes that build, test, and deploy software. This approach ensures that security checks are included at every stage of development, rather than being added at the end. By doing so, teams can identify and fix vulnerabilities early, reducing risks and improving the safety of the final product.

ERP Implementation

ERP implementation is the process of installing and configuring an Enterprise Resource Planning (ERP) system within an organisation. This involves planning, customising the software to meet business needs, migrating data, training users, and testing the system. The goal is to integrate various business functions such as finance, sales, and inventory into a single, unified system for better efficiency and decision-making.

Contract Management

Contract management is the process of creating, executing, and overseeing agreements between two or more parties. It involves making sure that all parties follow the terms, track important dates like renewals, and manage any changes or issues that arise. Good contract management helps organisations avoid risks, save money, and maintain strong business relationships.

Domain-Aware Fine-Tuning

Domain-aware fine-tuning is a process where an existing artificial intelligence model is further trained using data that comes from a specific area or field, such as medicine, law, or finance. This makes the model more accurate and helpful when working on tasks or questions related to that particular domain. By focusing on specialised data, the model learns the language, concepts, and requirements unique to that field, which improves its performance compared to a general-purpose model.
