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 can sidecar containers communicate with the application container via localhost?

Because containers in the same pod share the same network namespace, Containers in the same Kubernetes pod share the network namespace. This means they share the same IP address and can communicate via localhost without any network hop, as if they were processes on the same machine.

What is the main advantage of using a sidecar over an SDK library for cross-cutting concerns?

Sidecars work regardless of the application's programming language and don't require code changes, An SDK must be integrated into the application code and only works for that language. A sidecar is language-agnostic, it handles networking at the container level. Your Go service and your Python service both get the same capabilities without either needing library integration.

What problem does Kubernetes 1.28 native sidecar support solve?

It ensures sidecars start before the app and stop after it, fixing startup ordering issues, Before native sidecar support, sidecar containers were regular containers with no lifecycle ordering guarantees. If the sidecar proxy was not ready when the app started, initial requests would fail. Native sidecars use restartPolicy: Always in init containers, guaranteeing the sidecar is running before the main container starts.
