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.

Which single optimization typically has the LARGEST impact on latency for a global application?

Deploying servers and CDN caches closer to users, reducing the physical distance data must travel, Physics is the ultimate bottleneck. Light in fiber travels at 200 km/ms. Moving a server from 5,000 km away to 500 km away saves roughly 45ms round trip. No amount of compression, serialization, or server tuning can save 45ms. Geographic placement and CDN caching always yield the biggest latency wins.

Why does TLS 1.3 reduce latency compared to TLS 1.2?

TLS 1.3 completes the handshake in 1 round trip instead of 2, and supports 0-RTT resumption for returning connections, TLS 1.2 requires 2 round trips for the handshake. TLS 1.3 redesigned the handshake to complete in 1 round trip, saving 50-100ms depending on distance. For returning visitors, 0-RTT mode sends application data with the very first packet, eliminating handshake latency entirely (with replay attack trade-offs that must be handled at the application layer).

Why does Cloudflare's Argo Smart Routing reduce latency compared to standard internet routing?

Standard BGP routing optimizes for cost, not latency. Argo routes traffic over Cloudflare's private backbone, choosing the lowest-latency path instead of the cheapest path, BGP, the internet's routing protocol, optimizes for cost and policy, not latency. Traffic might cross 6 ISP networks on a suboptimal path. Argo routes over Cloudflare's private fiber backbone, bypassing congested peering points and choosing paths based on measured latency. The result: 30-40% reduction in time-to-first-byte on average.
