Choosing the right architecture is one of the most important decisions in system design.Two common approaches are monolithic architecture and microservices architecture. Each has its strengths, weaknesses, and ideal use cases. In this blog, we’ll clearly compare monoliths vs microservices, explain trade-offs, and help you decide when to use each. What Is a Monolithic Architecture? […]

In large-scale systems, reads dominate writes.Users expect fast responses, whether they’re searching, scrolling feeds, or loading product pages. This is why indexing and read optimization are critical parts of system design. In this blog, we’ll cover how indexes work, their trade-offs, and how search systems optimize reads at scale. What Is an Index? An index

As systems grow, performance and scalability become critical.Most real-world applications cannot rely on databases alone. This is where caching and proper storage choices play a key role in system design. In this blog, we’ll cover why caching is needed, how databases differ, and basic storage types—keeping it simple and practical. Why Caching Is Needed Databases

Understanding how distributed systems behave is critical for building reliable software.Two key concepts that guide system behavior are the CAP Theorem and ACID/BASE properties. This blog explains these concepts simply, so you can apply them in real-world designs and interviews. CAP Theorem CAP stands for Consistency, Availability, and Partition Tolerance. Key Points: Rule: In a

Scalability is one of the most important concerns in system design.It defines whether a system can grow smoothly as usage increases or collapses under pressure. Many engineers understand scalability in theory but struggle to reason about numbers.This blog focuses on simple, practical scaling concepts and basic estimation techniques that are easy to apply in real

System design is one of the most important skills for modern software engineers, yet it is also one of the most misunderstood. Many developers associate system design only with interviews, while others think it is relevant only for senior engineers or architects. In reality, system design is about thinking in systems — understanding how different

Every good system design starts with requirements.Before choosing databases, caches, or architectures, you must clearly understand what the system should do and how well it should do it. These two dimensions are known as functional requirements and non-functional requirements. Many system design failures — and interview failures — happen because engineers misunderstand or ignore this
