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 company produces 10,000 raw alerts per day. After dedupe (70% reduction), grouping, and severity filtering, roughly how many pages per day should reach on-call engineers across all teams?

About 100 pages per day spread across all teams, The noise reduction pipeline cuts 10k raw events to ~3k after dedupe, ~500 after grouping, and ~100 after severity filtering (only SEV1 and SEV2 page). Spread across teams, this lands at 3-5 pages per 12 hour shift per team.

Google SRE treats signal-to-noise ratio as an SLO. What is their target ratio?

4:1 or better (four actionable for every one non-actionable), Google SRE book formalizes the standard as a 4:1 signal-to-noise ratio. Anything below that threshold is treated as a reliability bug, and the owning team gets a ticket to tune or delete the offending rules.

Why does Shopify make post-incident classification mandatory before an incident can be closed?

To generate the data needed for signal-to-noise SLO measurement, Without mandatory classification data, the signal-to-noise SLO cannot be computed accurately. Making classification part of the incident close flow ensures every page is categorized (actionable, self-resolved, duplicate, or false positive), giving the weekly review reliable data to act on.
