Load Balancers, Reverse Proxies, API Gateways, and Service Meshes: A Complete Guide
A comprehensive guide to choosing between L4/L7 load balancers, reverse proxies, API gateways, and service meshes. Learn when to use each, how they work, real configurations, scaling strategies, and failure modes with practical examples from mobile commerce to gRPC.
Batch vs Stream Processing: MapReduce, Spark, Flink, and Kafka Streams
Deep dive into batch and stream processing architectures. Learn when to use MapReduce, Spark, Flink, or Kafka Streams, covering event time, watermarks, exactly-once semantics, Lambda vs Kappa architectures, and real-world trade-offs for analytics and billing pipelines.
Block, File, and Object Storage: EBS, EFS, S3, Parquet, and Iceberg Compared
A comprehensive guide comparing block (EBS), file (EFS), and object (S3) storage on AWS, plus data lake formats like Parquet and Iceberg. Learn when to use each, how they work, scaling patterns, and common failure modes through a video-sharing app example.

Replication and Consistency in Distributed Systems: Single-Leader, Multi-Leader, and Leaderless Topologies
A comprehensive guide to replication topologies in distributed systems. Learn single-leader, multi-leader, and leaderless replication, consistency models from linearizable to eventual, CAP and PACELC theorems, and how PostgreSQL, DynamoDB, Cassandra, and Spanner choose.
Storage Engines and Index Structures: B-Trees, LSM-Trees, Inverted Indexes, and Vector Indexes
Deep dive into the four storage structures behind modern databases: B-trees for transactional workloads, LSM-trees for write-heavy systems, inverted indexes for full-text search, and vector indexes for semantic similarity. Learn when to use each, how they work, and how they fail.
Client-Server Communication Protocols: REST, GraphQL, gRPC, WebSockets, SSE, and WebRTC
A comprehensive guide to choosing between REST, GraphQL, gRPC, WebSockets, SSE, and WebRTC for client-server communication. Learn when to use each protocol, how they work, scaling strategies, and common failure modes with practical examples from a live interview platform.
