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 junior developer asks why their staging server becomes unreachable after every reboot. What's the most likely cause?

The server has a dynamic IP that changes on reboot, making the old DNS record point to nothing, When a server has a dynamic IP and reboots, it gets a new address. But the DNS record still points to the old one. Assigning a static IP (Elastic IP on AWS, static IP on GCP) fixes this permanently.

In a modern cloud production setup, where does the static IP typically live?

On the load balancer, with dynamic IPs on the servers behind it, The standard pattern is: DNS points to a load balancer with a static IP (or stable DNS name). The actual application servers behind the load balancer use dynamic IPs and can be replaced, scaled, or rotated without affecting the public-facing address.
