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 should Elasticsearch NOT be used as a primary database?

It lacks ACID transactions, has eventual consistency, and isn't designed for the durability guarantees of a primary data store, Elasticsearch is optimized for search and analytics, not transactional integrity. It has no transactions, newly indexed documents may not be immediately searchable, and its durability model is weaker than traditional databases. Always use a primary database as the source of truth.

How does Elasticsearch achieve horizontal scalability for search?

By splitting indices into shards distributed across nodes, queries fan out to all shards and results are merged, Elasticsearch splits each index into shards spread across the cluster. A search request is scattered to all relevant shards in parallel, each searches its local data, and results are gathered and merged. Adding more shards and nodes scales capacity linearly.

What is the ELK stack used for?

Log ingestion, indexing, search, and visualization, centralized observability for applications, The ELK stack (Elasticsearch, Logstash, Kibana) is the dominant solution for centralized logging. Logstash ingests and transforms logs, Elasticsearch indexes and stores them, and Kibana provides dashboards and search interfaces for engineers.

What makes Elasticsearch's aggregation framework particularly useful for e-commerce?

It computes faceted counts (brand: 1,234 results, price range: 890 results) in real time for sidebar filters, Aggregations power the faceted navigation on every e-commerce site. 'Nike: 1,234 results,' 'Under $50: 456 results.' Elasticsearch computes these counts across millions of products in milliseconds, something general-purpose databases struggle with at scale.
