📌 Function as a Service Summary
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.
🙋🏻♂️ Explain Function as a Service Simply
Imagine you have a robot assistant who only appears when you call for a specific task, does the job, and then disappears until you need them again. Function as a Service works in a similar way, letting you run code only when needed without worrying about keeping a computer running all the time.
📅 How Can it be used?
Use Function as a Service to automatically resize images uploaded to an online gallery without running your own servers.
🗺️ Real World Examples
An online shop uses FaaS to send confirmation emails. When a customer places an order, a function is triggered to generate and send the email, handling thousands of orders without extra server setup.
A news website uses FaaS to update trending topics every few minutes. A scheduled function gathers the latest data, processes it, and updates the site, all without dedicated backend servers.
✅ FAQ
What is Function as a Service and how does it work?
Function as a Service is a way to run small bits of code in the cloud without having to worry about servers or hardware. You just write a function, upload it, and the cloud provider runs it whenever it is needed, taking care of all the background work. This makes it easy to build and update applications without getting tangled up in technical details about infrastructure.
Why would someone use Function as a Service instead of traditional servers?
Function as a Service is handy because you do not need to manage any servers, which saves time and effort. It automatically scales up or down depending on how many people are using your application, so you only pay for what you use. This makes it a cost-effective and flexible choice for many types of projects.
What are some common uses for Function as a Service?
People often use Function as a Service for things like handling website requests, processing data, or running background tasks that do not need to be on all the time. It is great for jobs that happen in bursts or need to respond quickly to certain events, such as uploading a photo or receiving a message.

Secure DevOps Pipelines
Secure DevOps pipelines are automated workflows for building, testing, and deploying software, with added security measures at every stage. These pipelines ensure that code is checked for vulnerabilities, dependencies are safe, and sensitive data is protected during development and deployment. The goal is to deliver reliable software quickly, while reducing the risk of security issues.
Data Virtualization Strategy
A data virtualization strategy is a plan for accessing and integrating data from different sources without physically moving or copying it. It allows users to see and use data from multiple places as if it is in one location. This approach helps organisations make faster decisions and reduces the need for complex data transfers or duplication.
Model Calibration Frameworks
Model calibration frameworks are systems or sets of methods used to adjust the predictions of a mathematical or machine learning model so that they better match real-world outcomes. Calibration helps ensure that when a model predicts a certain probability, that probability is accurate and reliable. This process is important for making trustworthy decisions based on model outputs, especially in fields where errors can have significant consequences.
Pruning-Aware Training
Pruning-aware training is a machine learning technique where a model is trained with the knowledge that parts of it will be removed, or pruned, later. This helps the model maintain good performance even after some connections or neurons are taken out to make it smaller or faster. By planning for pruning during training, the final model is often more efficient and accurate compared to pruning a fully trained model without preparation.
HTTP Security Headers
HTTP Security Headers are special instructions added to the responses sent by web servers to browsers. These headers tell browsers how to behave when handling website content, adding extra layers of protection against certain types of cyber attacks. By using these headers, websites can help prevent issues like cross-site scripting, clickjacking, and content sniffing, making them safer for users.
