The client-server architecture is a distributed application framework consisting of clients and servers in which the server hosts, manages, and delivers the client’s services. Here clients are connected to a central server, and they communicate over a network or internet connection through a computer network.
Load balancers can receive and distribute requests to a particular server based on various load balancing techniques. These techniques use different algorithms to select servers based on a specific configuration. These algorithms are categorized into two parts: Static load balancing, 2) Dynamic load balancing
Latency is an essential concept that determines how fast the data transfers from the client to the server and back to the client. The lower the Latency, the better the performance. This blog will focus on the conceptual understanding of Latency, how it impacts the system's performance, and measures to improve Latency.
In this blog, we will learn about Caching, an important fundamental concept in system design. Have you ever experienced that when you open a website the first time, it takes more time than usual, but when you open the same website again, it takes no time to load? Do you know why this happens? Let's find out!
Availability is the percentage of time in a given period that a system is available to perform its task and function under normal conditions. One way to look at it is how resistant a system is to failures. High Availability comes with its own tradeoffs, such as higher latency or lower throughput.
Throughput is defined as the total number of items processed per unit of time or the rate at which something is produced. It is generally represented as the number of bits transmitted per second or HTTP operations per day. In this blog, we’ll be talking about the importance of Throughput in designing any system.
Process management involves executing various tasks such as creating processes, scheduling processes, managing deadlock, and termination of processes. It is the responsibility of the operating system to manage all the running processes of the system. In this blog, we will learn about process management and various algorithms related to it.
A key-value database is a non-relational database (NoSQL) that stores data using a simple key-value mechanism. Its structure is similar to maps or dictionaries, where each key is associated with one value only. The simplicity of this model makes a key-value database fast, easy to use, scalable, portable, and flexible.
System design is one of the critical topics that large tech companies ask about during the interview. On the other hand, it is also necessary for solving large-scale software problems. This blog will help you get familiar with concepts important for solving system design questions and learning system design at an advanced level.
Data Partition(Sharding) is a technique of dividing the data into independent components. It is a way of partitioning data into smaller pieces so that data can be easily accessed and managed. Partitioning is the backbone of modern distributed database management systems, which helps to improve scalability, manageability, and availability of the system.
Load balancing is essential for building high-performance and scalable applications. It is also a popular topic for system design interviews. In terms of definition: a load balancer is a software or a hardware device that sits between clients and servers to balance the workload. It saves servers from overloading and increases system throughput.
The Publish/Subscribe pattern, sometimes known as pub/sub, is an architectural design pattern that enables publishers and subscribers to communicate with one another. In this arrangement, the publisher and subscriber rely on a message broker to send messages from the publisher to the subscribers. Messages (events) are sent out by the host (publisher) to a channel, which subscribers can join.
MapReduce is a batch processing programming paradigm that enables massive scalability across a large number of servers in a Hadoop cluster. It was published in 2004, was called “the algorithm that makes Google so massively scalable.” MapReduce is a relatively low-level programming model compared to the parallel processing systems developed for data warehouses many years previously.
The objective of leader election is to provide one item (a process, host, thread, object, or human) specific powers in a distributed system. These specific abilities could include the capacity to delegate tasks, the ability to edit data, or even the responsibility for managing all system requests.
Databases are a critical component of the world’s most complex technology systems, and how they are used has a significant impact on their performance, scalability, and consistency. Because this is an essential topic with many moving components, hence in this article, we’ve outlined the most crucial database topics that you’ll need to know during a system design interview.
At its most basic level, a rate limiter restricts the number of events a certain object (person, device, IP, etc.) can do in a given time range. In general, a rate limiter caps how many requests a sender can issue in a specific time window. Rate Limiter then blocks requests once the cap is reached.
In the common client-server architecture, multiple clients will communicate with a central server. A peer-to-peer (P2P) architecture consists of a decentralized network of peers, which are nodes that can act as both clients and servers. Without a central server's need, P2P networks distribute workload among peers, and all peers contribute and consume resources within the network.
Polling is a technique that allows the servers to push information to a client. Long polling is a version of traditional polling that allows the server to send data to a client whenever available. It involves the Client requesting information from the server in the same way that standard polling does, but with the caveat that the server may not respond right away. A complete answer is delivered to the Client once the data is accessible.
Ever wondered how does 1-click-buy works on Amazon? How does an e-commerce platform show the status of your order after the order is placed? What happens when you cancel your order right after you place an order, or after your item is shipped, or even delivered? How is all the activity related to an order tied to just one order Id? This blog will try to tackle such system design challenges and lay out key insights on designing a workflow system.
CAP Theorem is an essential concept in distributed systems for designing networked shared data systems. It allows a distributed database system to have only two of these functionalities: Consistency, Availability, and Partition Tolerance. We can make trade-offs between the three available functionalities based on the unique use case for our system.
Whenever we build any Web Application dealing with real-time data, we need to consider delivering data to the Client. While building such a Web Application type, one needs to consider the best delivery mechanism, right! We are presenting a series of three concept blogs focusing on data transfer between clients and servers. In this blog, we are focusing on Server-Sent Events, and here, we will give you a complete insight into its internal working and the underlying features.
In computer networking, a proxy is a server that acts as an intermediary between a client and another server. In this blog, we discussed: What is a proxy server? How do proxy serves work? What are proxies used for? What are forward and reverse proxies?
Consistent Hashing is the most widely used concept in a distributed system as it offers considerable flexibility in the scaling of the application. This blog discusses the key concepts and approaches which comes in handy while scaling out the distributed storage system. Consistent Hashing is beneficial and frequently applied to solving various system related challenges and is quite helpful in System Design Interviews.
Distributed systems are crucial in designing fault-tolerant, highly scalable, and low latency services. This blog will introduce you to the fundamentals of distributed systems, their functioning, and how they are applicable in real-world scenarios.
