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 team spends 4 hours per week manually restarting pods that get OOM-killed. This task is manual, repetitive, automatable, requires no judgment, and the frequency scales with traffic. Is this toil?

Yes, it passes all six criteria in the Google SRE definition, Manual, repetitive, automatable, tactical, no enduring value, scales with service size. A Kubernetes liveness probe with proper memory limits would eliminate this task entirely.

Why does Facebook SRE recommend a 'script with human supervision' stage before running automation unattended?

To catch edge cases that the runbook did not anticipate while a human can still intervene, The supervised stage catches hidden assumptions and edge cases. The human intervenes when the script misbehaves, preventing production damage. Skipping this stage means edge cases are discovered at 2am when the unattended cron fails.

A task takes 10 minutes per month and requires reading three Slack threads for context before execution. What is the best approach?

Write a runbook and leave it manual because the contextual judgment and low frequency make automation costly relative to savings, At 10 minutes per month (2 hours per year), automation that takes 20+ hours to build has a 10-year payback period. The contextual Slack reading adds further complexity. A good runbook is the right answer.

Google caps SRE toil at 50% of the rotation. What happens when a team exceeds the cap?

The service is handed back to the development team or a project is funded to automate the top toil source, The 50% cap is a forcing function. The development team must either take responsibility for operational work or fund automation to bring the SRE toil below the threshold. Without this cap, toil grows to fill all available hours.
