Technology Glossary

Popular open-source relational database known for reliability, ease of use, and excellent read performance.

A native, distributed graph database featuring a GraphQL-native interface. Designed for horizontal scalability, it provides synchronous replication and distributed ACID transactions.

Fully managed, serverless NoSQL database service with single-digit millisecond latency, automatic scaling, and built-in security. Uses hash and range keys for flexible querying at any scale.

A tree data structure where each internal node has exactly four children. In system design, it is used to partition 2D space by recursively subdividing it into four quadrants or regions. Widely used for proximity searches and location-based services.

A spatial indexing technique that encodes latitude and longitude into a short string of alphanumeric characters. It uses a hierarchical structure where longer prefixes represent larger areas, allowing for efficient proximity queries via string prefix matching.

Distributed stream processing framework for stateful computations over unbounded and bounded data streams.

Unified analytics engine for large-scale data processing with support for SQL, streaming, ML, and graph processing.

Object storage service offering industry-leading scalability, availability, security, and performance.

Purpose-built time series database optimized for high-write and query workloads.

Native graph database platform for connected data, providing ACID transactions and intuitive Cypher query language.

A query language for APIs and a runtime for fulfilling those queries with your existing data. It provides a complete and understandable description of the data in your API, giving clients the power to ask for exactly what they need and nothing more.

Cloud-native API gateway built on NGINX, providing request routing, rate limiting, authentication, load balancing, and service discovery. Highly extensible through plugin architecture.

High-performance, distributed memory object caching system designed for simplicity and speed. Focuses on providing ultra-fast, volatile key-value storage for small chunks of arbitrary data.

High-performance, multithreaded fork of Redis designed for superior throughput and lower latency on modern multi-core servers. Fully compatible with Redis while offering advanced features like active-active replication.

Open-source distributed event streaming platform designed for high-throughput, low-latency, fault-tolerant publish-subscribe messaging. Used by 80% of Fortune 100 companies for real-time data processing and asynchronous message queuing.

Feature-rich, reliable open-source message broker implementing AMQP with support for complex routing patterns, message acknowledgments, and multiple communication protocols. Designed for asynchronous processing and task queues.

Fully managed message queuing service for decoupling and scaling microservices and serverless applications.

High-performance web server, reverse proxy, load balancer, and HTTP cache.

Reliable, high-performance TCP/HTTP load balancer and proxy server.

Modern, high-performance edge and service proxy designed for cloud-native applications.

Open-source container orchestration platform for automating deployment, scaling, and management of containerized applications.

Platform for developing, shipping, and running applications in containers.

Global CDN, DDoS protection, and edge computing platform with DNS, WAF, and performance optimization.

Fast, highly secure and programmable content delivery network by Amazon Web Services.

Service mesh solution providing service discovery, configuration, and segmentation functionality.

Serverless compute service that runs code in response to events and automatically manages compute resources.

Open-source monitoring and alerting toolkit designed for reliability and scalability.

Open-source analytics and interactive visualization platform for monitoring and observability.

Cloud-scale monitoring and security platform for infrastructure, applications, logs, and user experience.
