40 Must Read Engineering Blogs to Learn System Design and Software Architecture in 2025

 Hello guys, mastering System design and software architecture is hard as they are very vast and there are a lot of concepts in play. I have been doing programming for close to 25 years now and I have worked on all kind of applications like starting from tiny 10KB mobile applications to monolithic applications where it take 30 minutes to just checkout the code.


I have worked on stateless applications and stateful applications, I have also worked on low latency applications and where latency doesn’t matter much.

From all these experience what I have found that In order to master System design and software architecture, its not enough to just know concepts and software architecture components, you also need to know how and when to use them.


Not just that you also need to know how to improvise them to meet your requirement and there is no better way to learn that then learning engineering blogs from top tech companies like Netflix, Uber, AWS, Google, Azure, Microsoft, Spotify etc.


In the past, I have shared best System Design courses, books, websites, newsletters, cheat sheets, mock interviews and 100+ System Design Interview Questions and Problems and today I am going to share 40 engineering blogs you can read e in 2025.


In the ever-evolving world of software engineering, system design has become a crucial skill for developers looking to build scalable, efficient, and robust applications.


Whether you’re preparing for technical interviews or aiming to enhance your architectural knowledge, learning from industry leaders is an invaluable strategy.


By reading these 40 engineering blogs you will learn deep insights into system design practices at some of the world’s most innovative companies.


By the way, if you are preparing for System design interviews and want to learn System Design in a limited time then you can also checkout sites like ByteByteGo, Codemia.io, Design Guru, Exponent, Educative and Udemy which have many great System design courses


Why Read Engineering Blogs?

Before we dive into the list, let’s consider why these engineering blogs are so valuable and how they help you to learn System design and software architecture:


  1. Real-World Examples
  2. These blogs often provide case studies of actual problems solved at scale. For example by reading Netflix blog you can get an idea of how they are managing membership of their 230 million subscribers and how they are recommending the content to keep you watching hours and hours.
  3. Cutting-Edge Technologies
  4. You also learn about the latest tools and technologies used in production environments which you may not be using, for example these large tech companies often innovate things like Kubernetes, Docker, Machine Learning which you may not find in other companies.
  5. Best Practices
  6. Reading these blogs also a good way to discover industry-standard practices for designing complex systems. There is no point re-inventing the wheel, learn what is already tried and tested and reading these blogs is great first step.
  7. Problem-Solving Approaches
  8. By reading these engineering blogs you will also understand how top engineers approach and solve challenging problems.
  9. Architecture Insights
  10. By reading them you can also gain insights into the architecture of some of the most popular platforms you use daily.

Apart from that you will learn about several real world problems and how they are solved at scale, which is as good as doing them and believe me you will not get many chances in your own career, so learning from other’s experience is best strategy here.


By the way, if you don’t get enough time, you can also subscribe to newsletters like ByteByteGo, Design Guru, and SystemDesign.one where you can get one of two email every week where they read these blog and share insights. If you need more choices, you can also see my article on same topic

Microsoft adds Windows protections for malicious Remote Desktop files

Microsoft has introduced new Windows protections to defend against phishing attacks that abuse Remote Desktop connection (.rdp) files, adding warnings and disabling risky shared resources by default. RDP files are commonly used in enterprise environments to connect to remote systems because admins can preconfigure them to automatically redirect local resources to the remote host. Threat actors have increasingly abused this functionality in phishing campaigns. The Russian state-sponsored APT29 hacking group has previously used rogue RDP files to remotely steal data and credentials from victims. When opened, these files can connect to attacker-controlled systems and redirect local drives to the connected device, allowing the attacker-controlled device to steal files and credentials stored on disk. They can also capture clipboard data, such as passwords or sensitive text, or redirect authentication mechanisms like smart cards or Windows Hello to impersonate users https://hackmd.io/@alexaa...

How to write technical blog posts that people actually read?

 Applying recently learned knowledge is one of the best way to reinforce our learning. Turning around and teaching it to somebody else through technical blog post is excellent way to do it. Technical blogging is critical to early growth as a community. The motive of this article is not only to provide medium guidelines but also write technical blog posts that people will actually read. So, how to write such technical blog post? I have divided it into three major sections and we will discuss each one of them. Preparing raw content i.e. substance Tying up everything and packaging Publicizing i.e. making widely known Preparing raw content (Substance) Writing something that matters is challenging. We should do a lot of homework to create a quality content. Knowing the topic you’re writing about and what’s been already written about it is the first thing that’s required. After you are done with your homework, figure out what’s missing. You may feel that everything about the topic is wri...
