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.

How does a red team exercise differ from a penetration test?

Red teams simulate persistent, realistic attacks over weeks with minimal scope restrictions, testing detection and response. Pen tests focus on finding vulnerabilities within a defined scope and two-week timeline., Pen tests find vulnerabilities. Red team exercises test whether the organization can detect and respond to a realistic, persistent attack. The scope is broader, the timeline is longer, and detection evasion is part of the exercise.

Why is lateral movement detection consistently the weakest area for blue teams?

Internal traffic between hosts uses legitimate protocols (RDP, SMB, WMI) that look the same whether it is a sysadmin or an attacker, making detection rules hard to write without excessive false positives, An attacker using RDP to pivot from one server to another looks identical to a sysadmin doing the same thing. Writing detection rules that distinguish legitimate admin activity from attacker lateral movement requires behavioral baselines, anomaly detection, and careful tuning.

What is a purple team exercise?

Red and blue teams working collaboratively, where red explains each attack technique and blue writes detection rules in real-time, Purple teaming removes the adversarial element. Red explains their TTPs in real-time. Blue sees exactly what to detect. Detection rules are written, tested, and deployed during the exercise. This is often more valuable than a traditional red/blue exercise because gaps are closed immediately.
