Performance Optimization Strategies in Highly Scalable Systems
Thu, 28 Sep 2023
In today's digital landscape, it's not just about building functional systems; it's about creating systems that scale smoothly and efficiently under demanding loads. But as many developers and architects can attest, scalability often comes with its own unique set of challenges. A seemingly minute inefficiency, when multiplied a million times over, can cause systems to grind to a halt. So, how can you ensure your applications stay fast and responsive, regardless of the demand?
In this article, we'll delve deep into the world of performance optimization for scalable systems. We'll explore common strategies that you can weave into any codebase, be it front end or back end, regardless of the language you're working with. These aren't just theoretical musings; they've been tried and tested in some of the world's most demanding tech environments. Having been a part of the team at Facebook, I've personally integrated several of these optimization techniques into products I've helped bring to life, including the lightweight ad creation experience in Facebook and the Meta Business Suite.
Spring Boot and React in Harmony
Thu, 28 Sep 2023
For many full-stack developers, the combination of Spring Boot and React has become a staple in building dynamic business applications. Yet, while powerful, this pairing has its set of challenges. From type-related errors to collaboration hurdles, developers often find themselves navigating a maze of everyday issues.
Enter Hilla, a framework that aims to simplify this landscape. If Hilla hasn't crossed your radar yet, this article will provide an overview of what it offers and how it can potentially streamline your development process when working with Spring Boot and React.
If you’re still building and delivering your software applications the traditional way, then you are missing out on a major innovation in the software development process or software development life cycle. To show you what I’m talking about, in this article, I will share how to create a CI/CD Pipeline with Jenkins, Containers, and Amazon ECS that deploys your application and overcomes the limitations of the traditional software delivery model. This innovation greatly affects deadlines, time to market, quality of the product, etc. I will take you through the whole step-by-step process of setting up a CI/CD Docker pipeline for a sample Node.js application.
What Is a CI/CD Pipeline?
A CI/CD Pipeline or Continuous Integration Continuous Delivery Pipeline is a set of instructions to automate the process of Software tests, builds, and deployments. Here are a few benefits of implementing CI/CD in your organization.
Auto-Scaling DynamoDB Streams Applications on Kubernetes
Tue, 26 Sep 2023
This blog post demonstrates how to auto-scale your DynamoDB Streams consumer applications on Kubernetes. You will work with a Java application that uses the DynamoDB Streams Kinesis adapter library to consume change data events from a DynamoDB table. It will be deployed to an Amazon EKS cluster and will be scaled automatically using
The application includes an implementation of the
com.amazonaws.services.kinesis.clientlibrary.interfaces.v2.IRecordProcessor that processes data from the DynamoDB stream and replicates it to another (target) DynamoDB table - this is just used as an example. We will use the AWS CLI to produce data to the DynamoDB stream and observe the scaling of the application.
Common Problems in Redux With React Native
Tue, 26 Sep 2023
Redux is a popular state management library used with React and React Native to manage the application's state efficiently. While Redux provides many benefits, it can also present some challenges, especially when used in the context of React Native mobile app development. In this blog, we'll explore some common problems developers encounter when using Redux with React Native and how to address them.
1. Boilerplate Code
Redux is known for its boilerplate code, which can be extensive. React Native projects tend to benefit from lean and concise codebases, so Redux's verbosity can be overwhelming. To mitigate this issue, consider using libraries like Redux Toolkit, which simplifies the setup and reduces boilerplate code.
Seasoned software engineers long for the good old days when web development was simple. You just needed a few files and a server to get up and running. No complicated infrastructure, no endless amount of frameworks and libraries, and no build tools. Just some ideas and some code hacked together to make an app come to life.
Whether or not this romanticized past was actually as great as we think it was, developers today agree that software engineering has gotten complicated. There are too many choices with too much setup involved.
TypeScript: Useful Features

Type guards help us to get info about a type within a conditional block. There are a few simple ways to check the type using
instanceof operators, or using equality comparison (
Why Angular and ASP.NET Core Make a Winning Team
Wed, 20 Sep 2023
The seamless functioning of an application requires a robust build and flawless coordination between its front-end and back-end technologies. The front end is responsible for defining the UI and UX of an app, while the back end powers its features and handles logic.
That’s why it is imperative that developers come up with a combination of technologies that ensures maximum feasibility between both ends, thereby empowering the creation of a robust, functional application.
HLS in Depth
Wed, 20 Sep 2023
HLS (HTTP Live Streaming) is a live streaming protocol that leverages current widespread HTTP technologies to deliver live video + audio experiences to large audiences.
Initially developed by Apple in 2009, it has gained wide adoption across devices ranging from desktops and mobile phones to smart TVs. The iPhone drove its initial adoption, and having a significant market share in the mobile space, its supporting HLS by default was an excellent booster.
I remember the first time I saw a demonstration of Ruby on Rails. With very little effort, demonstrators created a full-stack web application that could be used for real business purposes. I was impressed – especially when I thought about how much time it took me to deliver similar solutions using the Seam and Struts frameworks.
Ruby was created in 1993 to be an easy-to-use scripting language that also included object-oriented features. Ruby on Rails took things to the next level in the mid 2000s – arriving at the right time to become the tech-of-choice for the initial startup efforts of Twitter, Shopify, GitHub, and Airbnb.
