A Discussion on Stateless & Stateful Services (Managing User State on the Backend)
In most articles I come across on stateless and stateful services, stateful service architectures are viewed less favorably in contrast to stateless services primarily due to the horizontal scalability challenge they bring along. It is always recommended to implement a stateless service architecture as opposed...
Single-threaded Event Loop Architecture for Building Asynchronous, Non-Blocking, Highly Concurrent Real-time Services
Real-time services like chat apps, MMO (Massive Multiplayer Online) games, financial trading systems, apps with live streaming features, etc., deal with heavy concurrent traffic and real-time data. These services are I/O bound as they spend a major chunk of resources handling input-output operations such as...
Database Architecture – A Deep Dive – Part 1
This article is a deep dive into the internal architecture of databases/DBMS (Database Management Systems). I’ll begin with a standard architecture relational databases have; will then take a peek into the architectures of a couple of real-world SQL databases and then, in the subsequent articles,...
IP layers and the TCP/IP model – A deep dive
This blog post takes a deep dive into the intricacies of communication over the web with the IP (Internet Protocol), its layers involved and the TCP/IP protocol suit. By the end of the post, you’ll have a good insight into how machines communicate/exchange data over...
Application architecture explained in-depth with a real-world example
In my previous post on application architecture, I discussed various components that form a scalable web application architecture. That article will help you understand the basic building blocks of application architecture. Besides explaining the fundamental components, I’ve also designed the bare-bones architecture of a sports...
Leveraging the Backends for frontends pattern to avert API gateway from becoming a system bottleneck
In this system design series, I discuss the intricacies of designing distributed scalable systems and the related concepts. This will help you immensely with your software architecture and system design interview rounds, in addition to helping you become a better software engineer. Here is the first post...
Understanding API Gateway and the need for it
In this system design series, I discuss the intricacies of designing distributed scalable systems and the related concepts. This will help you immensely with your software architecture and system design interview rounds, in addition to helping you become a better software engineer. Here is the first...
CDN and Load balancers (Understanding the request flow)
In this system design series, I’ve started on this blog, I discuss the intricacies of designing distributed scalable systems and the related concepts. This will help you immensely with your software architecture and system design interview rounds, in addition to helping you become a better...
How Actor model/Actors run in clusters facilitating asynchronous communication in distributed systems
This blog post is a continuation of my previous post, in the system design series, on understanding the actor model to build non-blocking, high-throughput distributed systems. If you haven’t read it, I suggest giving it a read. Various Actor model frameworks, like Akka, ProtoActor, Actix,...
Understanding the Actor model to build non-blocking, high-throughput distributed systems
This is the fourth post in the system design series where I discuss the intricacies of designing distributed scalable systems and the related concepts. This will help you immensely with your software architecture and system design interview rounds, in addition to helping you become a better...
Monolithic architecture simplified
This write-up takes a deep dive into monolithic architecture. We will understand what it is and why implement it. What is monolithic architecture? An application has a monolithic architecture if it contains the entire application code in a single codebase. A monolithic application is a...
‘Futures and Promises’ – How Instagram leverages it for better resource utilization
Futures and Promises is a concept that enables a process to execute asynchronously, improving performance and resource consumption. It can be applied in multiple contexts, such as in request-response in a web service call, long-running computations, database queries, remote procedure calls, interservice communication in distributed...
