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.

Google's SRE book recommends a maximum of how many on-call shifts per quarter per engineer?

2 shifts per quarter, Google SRE guidance caps on-call at 2 shifts per quarter. Exceeding this correlates with increased attrition. Teams with fewer than 5 people in rotation cannot stay under this limit with weekly shifts.

What is the minimum number of engineers per region for a viable follow-the-sun rotation?

4 per region (12 total), With 4 engineers per region, each person is on call once per month. Fewer than 4 per region means some engineers take multiple shifts per month, which defeats the burnout reduction goal of follow-the-sun.

Why does Stripe's SRE handbook require video calls for shift handoffs instead of written docs alone?

Body language and verbal tone convey uncertainty and gut feelings that do not survive in writing, An outgoing engineer might have a bad feeling about a service that has not produced alerts but seems off. That intuition transfers on a video call through tone and body language but is almost always omitted from written handoff documents.
