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.

Why is network location insufficient for authenticating services?

A compromised service on the same network can impersonate any other service if there is no authentication, Being on the internal network does not prove identity. An attacker who compromises any single service gains network access and can call any other service that trusts network location instead of verifying identity.

What problem does SPIFFE solve that mTLS alone does not?

SPIFFE provides a standardized, portable identity framework that works across Kubernetes, VMs, and multi-cloud environments, mTLS provides authentication but does not standardize how identities are defined or managed across different environments. SPIFFE creates a universal identity scheme (spiffe:// URIs) with automated certificate management via SPIRE that works across any infrastructure.

In an Istio service mesh, where does mTLS termination and policy enforcement happen?

In the Envoy sidecar proxy, transparently to the application, Istio injects an Envoy sidecar next to every pod. The sidecar intercepts traffic, handles mTLS, verifies identity, and checks AuthorizationPolicy before forwarding the request to the application container. The app sees plain HTTP.
