Continuing with our System Design series we’ll be discussing message queue, an essential component in building scalable, decoupled systems. Message queues help systems handle communication between different parts asynchronously, ensuring smooth data flow even during heavy traffic. What is a Message Queue? A message queue is a system that allows different parts of a system to communicate with each other in an asynchronous manner. It acts as a buffer between a producer (the part that sends messages) and a consumer (the part that processes messages), allowing the producer to continue…

Let’s continue the journey in System Design. In this post, we’ll explore the concept of forward and reverse proxy, which play a crucial role in optimizing and securing web traffic. Proxies act as intermediaries, improving efficiency, security, and management of requests between clients and servers. What is a Proxy? A proxy is essentially an intermediary that sits between a client and a server, forwarding requests and responses between the two. It can be used for various purposes such as load balancing, security, caching, and more. Real-World Example: Imagine a bookstore…

Let us continue our System Design series! In this post, we’ll dive into the concept of indexing in databases. Indexing is a technique that allows for faster data retrieval by organizing and optimizing the way data is stored. What is Indexing? Indexing is like creating a shortcut for finding the right data quickly. Instead of scanning the entire database, the index helps you jump directly to the location of the data you need, improving the performance of your queries. Real-World Example: Let’s go back to our bookstore analogy. Imagine you…

Welcome again to System Design series! In this post, we will explore the concept of databases, which are fundamental to storing, organizing, and managing data in any application. Databases are the backbone of any data-driven system, providing the infrastructure needed to handle, retrieve, and manipulate data efficiently. What is a Database? A database allows users to easily access, manage, and update a structured collection of data. It serves as a digital ledger, storing information in an organized way, allowing quick retrieval and manipulation of data. Real-World Example: In our bookstore…

Welcome back to the System Design series! In this post, we will explore the concept of caching, a powerful technique used to enhance the speed and performance of applications. Caching plays a critical role in optimizing data retrieval and ensuring a smooth user experience. What is Caching? Caching is a technique where systems store frequently accessed data in a temporary storage area, known as a cache, to quickly serve future requests for the same data. This temporary storage is typically faster than accessing the original data source, making it ideal…

My next post in System Design series! In this post, we will explore the concept of Load Balancers. Load balancing is a crucial component in building scalable and reliable systems, ensuring that your application can handle varying loads efficiently and continue to provide a smooth user experience. What is a Load Balancer? A Load Balancer is a device or software that distributes incoming network traffic across multiple servers. The goal is to ensure that no single server becomes overwhelmed, thus improving the performance and reliability of the application. Real-World Example:…

Welcome to the second post in our System Design series! Today, we will delve into the Client-Server Model, a foundational concept in system design. This model underpins much of the internet and distributed computing, making it essential to understand for anyone involved in building scalable systems. What is the Client-Server Model? The Client-Server Model is a distributed application structure that partitions tasks or workloads between providers of a resource or service, called servers, and service requesters, called clients. Typically, clients and servers communicate over a network, making it possible for…

Welcome to my new series on System Design! This series aims to demystify the concepts of system design, making them accessible and easy to understand. Whether you’re preparing for interviews or looking to build scalable systems, this series will provide you with the foundational knowledge you need. Why System Design? System design is crucial for several reasons: Real-World Example: Consider running a bookstore. Initially, you might handle everything manually – tracking inventory, managing orders, and so on. However, as your business grows, this approach becomes impractical. You need a system…
