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.

A dashboard calls 5 microservices to compose one page. What is the most efficient call pattern?

Call all 5 in parallel and merge the results. Total time equals the slowest service, not the sum., Parallel calls reduce latency from the sum of all service times to the maximum single service time. If each service takes 100ms: sequential = 500ms, parallel = 100ms. Always call independent services in parallel.

Service 3 of 5 is down. The API composition layer should:

Return partial data from the 4 available services with a flag indicating Service 3's data is unavailable, Partial data is almost always better than no data. A dashboard missing the 'billing' panel is more useful than an error page. Return what you have, mark the missing section, and let the frontend render a placeholder.

The composer's timeout should be set relative to the client's timeout. Why?

The composer's deadline must be shorter than the client's timeout, otherwise the client gives up before the composer responds, wasting the work, If the client times out at 3 seconds and the composer waits 5 seconds for a straggler, the client already disconnected and the composed response is thrown away. Set the composer deadline at 60 to 70% of the client timeout. This leaves room for serialization, network transit, and client processing.
