We’ve become so influenced by technology that we are becoming more dependent on applications whether it’s for sleep tracking, streaming TV shows, or cricket matches. In the tech world, the adaptability of technology has become more advanced. As per recent reports, every day approx. 3800 applications are being pushed on the play store that includes apps for gaming, OTT, utility, productivity, etc.
You must’ve wondered how these applications work at the back end and how seamlessly they communicate with each module when any CTA is triggered. Being a developer, you should and must know these components and architecture to understand the working algorithm of data transmission through the system. Although it’s not mandatory for freshers to have depth knowledge of system design, the earlier you’ll learn, the easier it would be for you to ace up your career. To support this, we’ve hand-picked the 10 best System Design courses for beginners as well as experienced ones along with key features of this course.
What is System Design?
As mentioned above, if you’re thinking about how big applications like Netflix, Amazon, Hotstar, etc. work from the backend – let us tell you the real magic is designing a system that can work on each module or component. In a nutshell, System Design is the process of designing the architecture, components, and interfaces for a system to satisfy the specific needs and requirements of end-users.
Speaking of which, these engineers are responsible for making their product for (Netflix, Facebook, etc.) scaling up at a mass level. In short, System Design is all about maintaining the relationship between Scalability – Reliability – Availability.
Almost every big tech company including Facebook, Microsoft, Amazon, etc. asks various questions based on System Design while hiring software developers or software engineers. Also, if you’re preparing for an SDE 2 or SDE 3, learning System Design becomes more necessary to crack the interviews.
