Discover the principles, patterns, and best practices of System Design, from architecture and scalability to reliability and performance. Build robust and efficient systems with expert insights!
In Episode 2, Prisha and her friends experienced chaos while constructing their LEGO towers. With bricks crumbling and design failures, they learned the Builder Pattern — how to construct complex structures step by step from blueprints. Friendopia’s towers finally stood tall and proud! âť—The Problem Friendopia was growing rapidly. Houses were constructed and towers erected, […]
🌇 Previously in Friendopia… After the chaos of a broken LEGO city, Mr. Kohli introduced Prisha and her friends, Arijay and Nimisha, to the magical world of design patterns. “Think of them,” he explained, “as clever tricks that help us to solve common problems.” They would begin today with one of the strongest: the Builder
🌇 The LEGO City Dream On a hot afternoon, Prisha, a wide-eyed 12-year-old with big ambitions, had invited her friends over. “Let’s create a LEGO city!” she cried out. “With roads and parks!” cried out Arijay. “And rocket launchpads!” boomed Nimisha. They took out their LEGO box filled with LEGO bricks. They constructed houses, cars,
A sudden “System Unavailable” error at Amusement Park leaves visitors stranded. The rides work, but access fails. Mr. Kohli explains that high Availability ensures no user gets left out. This blog covers HA vs. Fault Tolerance, key strategies, and essential metrics like SLA, SLO, RTO, and MTTR to keep systems “Always Open, Never Down.”
Explore scalability through the lens of a bustling New York amusement park where a roller coaster faces overwhelming crowds. Learn how software architects tackle this dilemma—upgrading a ride (vertical scaling) or adding new rides (horizontal scaling)—with smart strategies, trade-offs, and hybrid approaches to build resilient, cost-effective systems for modern growth.
Building a great system is like constructing a Lego city—without planning, things collapse! Join Prisha and her friend as they discover system design with Mr. Kohli. Learn how scalability, fault tolerance, and high availability power tech giants like YouTube and Amazon. Ready to design smarter systems? Let’s build, one Lego brick at a time! 🚀
After transforming Hospoint into microservices, the team faces a new challenge—ensuring the design lasts. Guided by Mr. Kohli, they enter The Temple of Good Design to uncover the Golden Rules of Microservices—avoiding shared databases, right-sizing services, aligning with business needs, and optimizing communication. Are your microservices built to last?
Hospoint, a healthcare system, struggled with monolithic bottlenecks before transforming into a scalable microservices architecture. Using the Strangler Fig Pattern, API Gateway, Kubernetes, and Docker, the transition resolved deployment risks, performance issues, and data consistency challenges. Discover how Hospoint overcame obstacles with Saga patterns, asynchronous communication, and observability tools to achieve agility and resilience.
