Cloud Computing And Its Architecture

Reading Time: 3 minutes What is Cloud Computing? Cloud computing is a way to delivered resources (such as servers, databases, software, etc.) over the internet and It also gives the power to create, design, and manage applications on the cloud platform. and it uses remote servers on the web to store, manage, and access data online instead of local drives. The data can be anything like files, images, documents, Continue Reading

Akka Streams | Three Basic Components

Reading Time: 3 minutes Akka, a free open source toolkit simplifying the construction of concurrent and distributed system/application. We have already deal with Akka Actors where we learnt about the Akka Actors and their Behaviors. But Actors can be seen dealing with with Sequence of Data where they send or receive series of messages. So, In this blog we discuss Akka Stream in bit detail. What is Akka Streams Continue Reading

Build & design highly available and resilient Fintech products

Reading Time: 7 minutes FinTech – by the definition from Oxford Dictionary, it means computer programs and other technology used to provide banking and financial services. When it comes to using Financial Services, every user of that service would want it to be available 24/7 i.e. no downtime and 100% user responsive. And this means that FinTech products, by nature, should always be available and user-responsive. But wait, how Continue Reading

Hexagonal Architecture a silver bullet for Fintech Application

We will see how this approach will tackle common fintech issues at the early development phase. It will also help us make the right decisions and define the appropriate strategy to meet business objectives. After working for more than 4 years in the Fintech domain, I have Continue Reading

Enabling CORS in Node.js

Reading Time: 2 minutes In the last blog, we’ve learnt the basic about the CORS, how we can setup and how it works. Now ini this blog, we’re going to learn how we can enable the it in node.js CORS is a browser security feature that restricts cross-origin HTTP requests with other servers and specifies which domains access your resources. Let’s say accessing images, videos, iframes, or scripts from Continue Reading

A Guide to CORS in Node.js with Express

Reading Time: 4 minutes Introduction Node.js is an open-source and cross-platform runtime used when executing JavaScript code on the server-side. One of the popular Node.js server frameworks is Express. Implementing CORS in Node.js helps you access numerous functionalities on the browser. Express allows you to configure and manage an HTTP server to access resources from the same domain. The three parts that form an origin are protocal, domain, and port. Let’s Continue Reading

Distributed Messaging Patterns | Reactive Architecture

Reading Time: 3 minutes In this blog we are gonna learn about messaging and patterns of messaging. We are gonna learn how asynchronous messaging works. Asynchronous messaging provides us a lot of flexibility in our system. As an example, we can take large portions of our system offline and have our users not notice any difference in functionality. We can also enhance scalability of our system. For example, if Continue Reading

Backpressure in Akka Stream

Reading Time: 4 minutes “Reactive Streams” — whenever we come across these words, there are two things that come to our mind. The first is asynchronous stream processing, and the second is non-blocking backpressure. In this blog, we are going to learn about the latter part. Understanding Backpressure Very simply put, the idea behind backpressure is the ability to say “hey slow down!”. Let’s start with an example that Continue Reading

Introduction to Domain Driven Design (DDD)

Reading Time: 3 minutes What is Domain? To define domain-driven-design we should first establish what we mean by domain. The common dictionary definition of the domain is a sphere of knowledge, influence, or activity. In the context of software engineering, it refers to the subject area on which the application is intended to apply. For example, if you are building an E-commerce software, in this case, sales will be Continue Reading

CAP Theorem | Building Scalable Systems | Reactive Architecture

Reading Time: 3 minutes CAP Theorem, a Distributed System must account for this theorem which means when two or more systems try to connect with each other they need to account this Theorem. In this blog, we are gonna discuss about this theorem and how we have to sacrifice any factor while communicating with another system. Apart from this we’ll also discuss some other related terminologies and theorems. CAP Continue Reading
