A TLS certificate manager automates the full lifecycle of digital certificates: issuance via ACME protocol, storage with encrypted private keys,
A service registry is the backbone of dynamic service discovery in microservice architectures. Rather than hardcoding service endpoints, every instance
An event bus is a pub/sub messaging system designed for event-driven architectures: services publish domain events, and multiple subscribers react
A message broker decouples producers from consumers by providing a durable, ordered, partitioned log. Producers append messages to topics; consumers
A distributed file system (DFS) provides a POSIX-like file interface over a cluster of machines, storing file data reliably across
A block storage system exposes raw storage as fixed-size blocks (typically 4 KB or 512 bytes) arranged into logical volumes.
An object storage system provides a flat, scalable store for arbitrary binary data (objects) addressed by a bucket name and
A vector database stores high-dimensional embedding vectors and enables fast approximate nearest neighbor (ANN) search — finding the top-K vectors
A time-series database (TSDB) is purpose-built for append-heavy, time-ordered metric data. Its key design decisions — chunk storage, timestamp and
A graph database stores entities as nodes and relationships as edges, with properties on both. Unlike relational databases that simulate
A column-family store organises data in a hierarchy: keyspace → table → partition → rows. The partition key determines which
Key-Value Store System: Overview A key-value store is the simplest distributed database: keys map to opaque binary values. Despite its
Document Store System: Overview A document store persists and retrieves arbitrary JSON documents. Unlike relational databases, it does not enforce
Synonym Expansion System: Overview Synonym expansion augments search queries with equivalent or related terms so that a search for “automobile”
