Is this a video course?

No. This is an interactive, slide-based learning platform. Each lesson has rich text, animated diagrams, live code editors, and quizzes. You learn by reading, interacting, and doing, not by watching videos passively.

How long do I have access?

Forever. Both pricing tiers are one-time payments with lifetime access. This includes all current 766 lessons and any future content we add.

What level of experience do I need?

None. We start from absolute basics like 'What is latency?' and build up to distributed consensus protocols. The Foundation level assumes zero prior knowledge of system design.

How much does the system design course cost?

7.99 US dollars for lifetime access globally, or 499 Indian rupees for lifetime access in India. One-time payment, no subscription, no hidden fees. 11 lessons are free with no signup required.

What technologies are covered?

Everything from DNS and load balancers to Kubernetes, Kafka, distributed databases, consensus protocols, stream processing, security architecture, and observability. We cover principles and real-world implementations used at Netflix, Google, Amazon, Uber, Stripe, and more.

Is this useful for system design interview preparation?

Yes. The lessons are structured around the exact topics asked in system design interviews at FAANG and top-tier companies. Interactive diagrams help you practice whiteboard-style explanations. Covers everything from URL shortener design to distributed payment systems.

How is this different from ByteByteGo or Educative?

766 interactive lessons (4x more than most competitors), 16 different diagram types that build step by step, real production examples from Netflix, Google, Amazon, Uber, and Stripe, and lifetime access for a one-time payment of $7.99 instead of annual subscriptions costing 100 to 200 dollars per year.

What is database federation?

Splitting a single database into multiple specialized databases, each handling a different domain or function, Federation partitions a monolithic database by domain, users in one database, orders in another, analytics in a third. Each database is independently sized, tuned, and scaled for its specific workload.

What is the biggest challenge introduced by database federation?

Cross-domain queries and transactions no longer work. JOINs across databases are impossible, and atomic cross-database transactions require complex patterns, When orders and products are in separate databases, you can't JOIN them with SQL. You can't atomically update both in one transaction. You need application-level joins, denormalization, saga patterns, or a data warehouse, all more complex than a single database.

When should you NOT federate your database?

When you haven't exhausted simpler optimizations like indexing, query tuning, and read replicas, Federation adds significant complexity. Before splitting databases, try indexing improvements, query optimization, connection pooling, and read replicas. These are simpler solutions that often provide enough headroom. Federate only when these options are exhausted.
