API Gateways Clearly Explained !!!

• What is an API Gateway?
• Why do we need to use API Gateway ?
• Visual Representation of API Gateway
• How does an API Gateway work ?
• Functionalities offered by API Gateway #1 What Is An API Gateway ?

• API Gateways are present at layer & of the OSI model & play an important part in distributed system design & microservice architecture

• It sits between clients & servers , acting as a reverse proxy & serving as a single entry point for all requests

• It simplifies the client-server interaction by also handling tasks such as authentication, request routing, rate limiting, SSL termination, request aggregation, validation & transformation

If you are learning DSA, you need to understand the orders of growth

Give me 2 minutes and I'll teach it to you Order of growth describes how the runtime of an algorithm increases as the input size grows.

It focuses on the dominant term in the time complexity expression, ignoring constants and lower-order terms.

Python CLASSMETHOD decorator clearly explained !!! Imagine you are working as a backend engineer for a company whose software is used by various retail outlets.

You've been tasked to create a class 'Product' which helps create a new product by taking in name, price & quantity_in_stock.

Reverse Proxy clearly explained !!!!

• What is a proxy ?
• Definition of reverse proxy
• Visual representation of reverse proxy
• Use cases of reverse proxy
• Load balancers vs reverse proxy #1 What Is A Proxy ?

• A proxy in system architecture is an intermediary server that sits between a client and a target server

• It handles requests on behalf of the client, acting as a "middleman"

• Proxies can serve various functions, including improving security, balancing traffic loads, caching content, and hiding the client's IP address

• In simpler terms, it acts as a gateway between users and the web, either forwarding requests from clients to servers or handling incoming requests on behalf of servers

In my 11 years of working in tech I've had ZERO bad appraisals

Today let's try to understand corporate appraisals.

• What are appraisals ?
• How do they work ?
• Reviews & Ratings
• Increasing your odds of getting a better appraisal !!! Disclaimer !!!

Appraisal processes vary from company to company & heavily linked with market conditions but the general framework used by most companies to give appraisals more or less remains the same & the points shared here are for knowledge sharing & not a framework
