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 does a load balancer inspect to perform host-based routing?

The Host header in the HTTP request, Host-based routing works by reading the Host header that's included in every HTTP request. The load balancer matches this hostname against its routing rules and forwards traffic to the appropriate backend service.

A company hosts api.shop.com, admin.shop.com, and docs.shop.com behind one load balancer. What routing pattern is this?

Host-based routing, different hostnames go to different backends, Three different subdomains (api, admin, docs) hitting one load balancer that routes to different backend services based on the hostname, that's textbook host-based routing.

Why do most production setups combine host-based AND path-based routing?

Because each pattern handles routing at a different level of granularity, Host-based routing separates traffic at the service level (api.* vs web.*), while path-based routing handles routing within a service (/v1/users vs /v1/orders). Using both gives you clean macro-level and micro-level traffic management.
