📌 Stateless Clients Summary
Stateless clients are systems or applications that do not keep track of previous interactions or sessions with a server. Each request made by a stateless client contains all the information needed for the server to understand and process it, without relying on stored context from earlier exchanges. This approach allows for simpler, more scalable systems, as the server does not need to remember anything about the client between requests.
🙋🏻♂️ Explain Stateless Clients Simply
Imagine you are sending letters to a company, and each letter explains everything the company needs to know about who you are and what you want. You do not expect the company to remember your previous letters, so you include all the details every time. This is similar to how stateless clients work, making each request self-contained.
📅 How Can it be used?
Stateless clients can be used to build scalable web applications where each user request is handled independently by the server.
🗺️ Real World Examples
Online shopping websites often use stateless clients for browsing products. Every time a user clicks on a product, the browser sends a request that includes all the necessary details, such as the product ID, without relying on previous browsing history stored by the server.
APIs for mobile banking apps are typically designed with stateless clients so that every transaction request, like checking a balance or making a payment, includes all the required authentication and action details, allowing the server to process it without recalling earlier interactions.
✅ FAQ
What does it mean when a client is stateless?
A stateless client is one that does not remember anything about its past interactions with a server. Every time it sends a request, it includes all the details the server needs to process it. This makes things simpler for the server, as it does not need to keep track of any ongoing conversations or sessions.
Why might someone choose to use stateless clients?
Stateless clients are popular because they help keep systems straightforward and more scalable. Since the server does not need to store any information about previous requests, it can handle more users at once and is less likely to get bogged down by extra data.
Are there any downsides to using stateless clients?
While stateless clients make servers simpler and more efficient, they can also mean that each request takes a little more effort to put together, since all the required information has to be included each time. Some features that rely on remembering past activity, like shopping baskets or user preferences, may need extra steps to work smoothly.

💡Other Useful Knowledge Cards
Automation ROI Tracking
Automation ROI tracking is the process of measuring the financial return gained from investing in automation tools or systems. It involves comparing the costs associated with implementing automation to the savings or increased revenue it generates. This helps organisations decide whether their automation efforts are worthwhile and guides future investment decisions.
Model Retraining Systems
Model retraining systems are automated frameworks or processes that update machine learning models with new data over time. These systems help keep models accurate and relevant as patterns and information change. By retraining models regularly, organisations ensure that predictions and decisions based on these models remain reliable and effective.
Implantable Electronics
Implantable electronics are small electronic devices designed to be placed inside the human body, usually through surgery. These devices can monitor, support, or replace biological functions, often helping people manage medical conditions. They must be safe, reliable, and able to work inside the body for long periods without causing harm.
AI for Churn Prediction
AI for churn prediction is the use of artificial intelligence techniques to forecast when a customer is likely to stop using a product or service. By analysing patterns in customer behaviour, purchase history, or engagement data, AI models can identify warning signs that someone might leave. This helps businesses act early to keep valuable customers and reduce losses.
Digital Forensics
Digital forensics is the process of collecting, analysing, and preserving digital evidence from computers, mobile devices, and other electronic systems. This evidence is used to investigate crimes or security incidents involving technology. The goal is to uncover what happened, how it happened, and who was responsible, while maintaining the integrity of the data for legal proceedings.
