System Design Patterns: Building Scalable Distributed System

System Design Patterns: Building Scalable Distributed SystemsStop memorizing architecture diagrams. Learn how to design scalable systems.You know how to write code.You know how to build APIS.You know how to work with databases.But when someone asks:“How would you design this system for 10 million users?”the problem suddenly becomes much bigger.How do you handle millions of requests?What happens when a service fails?How do you prevent your database from becoming a bottleneck?How do you handle millions of concurrent connections?How do you maintain consistency across distributed services?And most importantly…Why did you choose one architecture over another?That's what this course is about.Go Beyond Basic System DesignSystem Design is not about drawing boxes and arrows.It's about understanding the engineering problems behind those boxes.In this course, you won't simply memorize:“Use Kafka here.”“Use Redis there.”“Add a load balancer.”“Use sharding.”“Add a cache.”Instead, you'll learn to ask:Why?Why Kafka?Why Redis?Why a read replica?Why sharding?Why asynchronous communication?Why a circuit breaker?Why a distributed lock?And most importantly:What tradeoff are you making?At scale, there is rarely a perfect solution.Improving latency can increase cost.Increasing availability can introduce consistency challenges.Distributing data can make transactions harder.Adding retries can amplify traffic during an outage.Adding caching can introduce stale data and invalidation problems.Understanding these tradeoffs is the heart of System Design.What You'll LearnThroughout this course, you'll explore the patterns and techniques that repeatedly appear in large-scale distributed systems.Architecture TradeoffsLearn how to reason about architecture decisions, scalability, latency, throughput, reliability, consistency, and cost.Real-Time CommunicationUnderstand:PollingServer-Sent EventsWebSocketsService DiscoveryAPI GatewaysGossip ProtocolBackpressureSidecar PatternDatabase InternalsGo beyond simply knowing how to use a database.Understand:B-TreesLSM-TreesWrite-Ahead LoggingReplicationPartitioningIndexingRead ReplicasQuery OptimizationEXPLAIN ANALYZEData ScalingLearn how systems evolve when a single database is no longer enough.Explore:PartitioningHorizontal ShardingConsistent HashingData LocalityDenormalizationMaterialized ViewsCQRSReliability Failure HandlingLearn how to prevent one failure from becoming a system-wide outage.You'll explore:Circuit BreakersTimeoutsRetriesJitterRate LimitingBulkheadsLoad SheddingGraceful DegradationConcurrency Distributed TransactionsUnderstand what happens when multiple requests modify the same data at the same time.You'll learn:Race ConditionsAtomic OperationsPessimistic LockingOptimistic ConcurrencyDistributed LocksIdempotencyTwo-Phase CommitSaga PatternQueues, Events Asynchronous SystemsLearn how to build systems that can absorb traffic spikes and process work asynchronously.Explore:KafkaAmazon SQSRabbitMQJob QueuesVisibility TimeoutsRetry PoliciesDead-Letter QueuesPoison MessagesFailure HandlingEvent-Driven ArchitectureGo deeper into modern distributed architectures with:CQRSEvent SourcingChange Data CaptureFan-OutFan-InWorkflow OrchestrationChoreographySpecialized Distributed-System PatternsYou'll also explore powerful patterns and data structures including:Leader ElectionBloom FiltersMerkle TreesTombstonesRead RepairAnti-EntropyGeohashingSpatial IndexingTop-K Heavy HittersContent-Addressable StorageCRDTsStrangler Fig Pattern Learn Patterns Through ProblemsThis course does not teach patterns as isolated definitions.For each important pattern, we'll follow a practical learning approach:PROBLEM↓PATTERN↓HOW IT WORKS↓TRADEOFFS↓WHEN TO USE IT↓WHEN NOT TO USE IT↓SYSTEM DESIGN INTERVIEW DISCUSSIONThis approach helps you understand not only what a pattern is, but why it exists and when it makes sense. Prepare for System Design InterviewsSystem Design interviews aren't simply testing whether you remember the definition of sharding or Kafka.They're testing whether you can reason about a system.Can you understand requirements?Can you estimate scale?Can you identify bottlenecks?Can you reason about failures?Can you choose appropriate architectural patterns?Can you explain consistency requirements?Can you understand the consequences of your decisions?And when the interviewer changes a requirement…Can you adapt your design?This course is designed to help you build that way of thinking.Who Is This Course For?This course is designed for:Software developers preparing for System Design interviewsEngineers targeting Senior, Staff, or Principal-level rolesDevelopers who want to understand distributed systems more deeplyEngineers working on scalable production systemsDevelopers who know the basics of System Design and want to go deeperAnyone who wants to understand the patterns behind large-scale systemsWhether you're preparing for interviews at companies such as Amazon, Google, Microsoft, Meta, Netflix, Apple, or simply want to become better at designing production systems, this course is built to develop the reasoning skills required for complex System Design problems.What Makes This Course Different?This isn't about memorizing hundreds of architecture diagrams.It's about developing the ability to look at a problem and ask:What is the actual constraint?Where is the bottleneck?What happens when this component fails?What consistency do we need?Where should the data live?Should this operation be synchronous or asynchronous?What happens when traffic increases 10× or 100×?What tradeoff am I making?That is the mindset that allows you to design systems rather than simply reproduce someone else's architecture.By the End of This CourseYou should be able to approach System Design problems with a much more structured mindset.Instead of asking:“What architecture should I memorize?”you'll be able to ask:“What problem am I solving, what constraints matter, and which pattern best fits those constraints?”Because the goal isn't to memorize the instructor's architecture.The goal is to learn how to design your own.Start Your System Design JourneyIf you're ready to move beyond basic System Design…If you want to understand how scalable distributed systems are actually designed…If you want to reason about failures, concurrency, data, scalability, reliability, and tradeoffs…you're in the right place.Don't memorize architectures.Learn how to design them.Enroll now and start building the System Design mindset.
