Synchronous and asynchronous are two different types of programming implementations that confuse a lot of new developers. This knowledge is very essential to create performant and scalable systems.
In short, a synchronous program blocks further operation till the current task execution has been completed. On the other hand, an asynchronous program allows to start multiple tasks at once, then progress and finish in overlapping time. Here the term overlapping is important. In the rest of this article, we will try to understand these concepts in detail and how they can be used to create efficient programs. …
Scalability and reliability are measures of how well your application can be served to end-users. If you have a system that can serve millions of users without noticeable downtime, then we can say the system is highly scalable and reliable.
When you’re working with a product that has a large user base, a lot of things change. Google has to process at least 100K requests per second. Without a robust scalable architecture, it would have been absolutely impossible. Scalability and reliability are probably the major factors for which we need Software Engineers in the first place.
Multithreading and Multiprocessing are ways to utilize 100% of the CPU and create performant applications. If you work with complex web applications, machine learning models, or video/image editing tools then you have to tackle multithreading/multiprocessing sooner or later.
Let’s say you create an application for editing photos. When the photo has a very high resolution, you will see a very significant drop in performance. Why? Because image editing is mathematically expensive. It puts pressure on the processor. To improve performance, you have to introduce multiprocessing/multithreading. …
If you’re a beginner and want to have a tech career, you might be confused about all the career specialization choices. There are things like Machine Learning/AI, Data Science, Game Development, Quality Assurance, Cyber Security and of course, Web Development.
If you have already made up your mind and you have your reasons to choose a certain career path (excluding Web Dev), then, this post is not for you. Otherwise, I will try to convince you why you should start with Web Development as the first step:
- It has a high demand in the job market
- Web is the most…
Let’s say you have created an awesome web application that uses some Machine Learning to suggest movies you might like. Now what? You have to share it with the world so that people can use it, right? This is where deployment comes into play.
In this post, I will give a high-level idea of cloud deployment. You will be introduced to different terminologies and use cases. I will refrain from going into low-level technical details of deployment (like, how to host a Node.js web app). …
