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 git SHA the most traceable image tagging strategy?

Each git SHA uniquely identifies the exact code commit that produced the image, creating a direct link from any running container to its source code, With a git SHA tag, you can look at any running container, read its image tag (abc1234), and immediately find the exact commit in your git repository. This is invaluable for debugging: you know exactly what code is running, when it was built, and what changed since the last deployment.

What does tag immutability prevent?

It prevents an existing tag from being overwritten with a different image, ensuring that a tag always points to the same build, Without immutability, someone could push a new image with the tag v1.2.3, silently replacing the previous build. Servers that pull v1.2.3 now get a different image than before. Tag immutability enforces that once a tag is set, it is permanent. This provides the guarantee that a tag always means the same thing.

In the hybrid tagging approach, why does a single image get both a git SHA tag and a semver tag?

Git SHA provides perfect traceability (which commit built this image) while semver provides human readability (is this a major, minor, or patch release). Both tags point to the identical image., Tags are cheap pointers. Having myapp:abc1234 and myapp:v1.2.3 point to the same image costs zero extra storage. The SHA tag lets you trace any running container back to source code. The semver tag lets humans communicate about releases. Uber and Stripe both use this dual-tag pattern.
