AWS Cloud Databases

Modernize your data infrastructure with fully managed, purpose-built databases
Choose the right purpose-built engine

Build use case-driven, highly scalable, distributed applications suited to your specific needs. AWS offers 15+ purpose-built engines to support diverse data models, including relational, key-value, document, in-memory, graph, time series, wide column, and ledger databases.

Run fully managed databases

Free your teams from time-consuming database tasks like server provisioning, patching, and backups. AWS fully managed database services provide continuous monitoring, self-healing storage, and automated scaling to help you focus on application development.

Achieve performance at scale

Start small and scale as your applications grow with relational databases that are 3-5X faster than popular alternatives, or non-relational databases that give you microsecond to sub-millisecond latency. Match your storage and compute needs easily, often with no downtime.

Rely on high availability and security

Support multi-region, multi-primary replication, and provide full data oversight with multiple levels of security, including network isolation and end-to-end encryption. AWS databases deliver the high availability, reliability, and security you need for business-critical, enterprise workloads.

Database services

Database type
AWS service

Relational Database

Relational databases store data with predefined schemas and relationships between them. These databases are designed to support ACID transactions, and maintain referential integrity and strong data consistency.

Traditional applications, enterprise resource planning (ERP), customer relationship management (CRM), ecommerce, generative AI use cases (such as chatbots with Retrieval Augmented Generation, similarity search, recommendation systems, and more)

Amazon Aurora

MySQL and PostgreSQL-compatible relational database built for the cloud. Performance and availability of commercial-grade databases at 1/10th the cost 


Amazon Relational Database Service (RDS)

Set up, operate, and scale a relational database in the cloud with just a few clicks


Amazon Redshift

Analyze all of your data with the fastest and most widely used cloud data warehouse


Key-value Database

Key-value databases are optimized for common access patterns, typically to store and retrieve large volumes of data. These databases deliver quick response times, even in extreme volumes of concurrent requests.

High-traffic web applications, ecommerce systems, gaming applications, generative AI use cases (such as similarity search using DynamoDB zero-ETL integration with Amazon OpenSearch Service)

Amazon DynamoDB

Get a fast, flexible, and serverless NoSQL database for any scale, to support key-value and document workloads


In-memory Database

In-memory databases are used for applications that require real-time access to data. By storing data directly in memory, these databases deliver microsecond latency to applications for whom millisecond latency is not enough.

Caching, session management, gaming leaderboards, geospatial applications, generative AI use cases (such as chatbots with Retrieval Augmented Generation, semantic caching, recommendation systems, fraud detection, and more)

Amazon MemoryDB for Redis

Compatible, durable, in-memory database service for ultra-fast performance.


Amazon ElastiCache

Unlock microsecond latency with a scalable caching service, compatible with Redis or Memcached.


Document Database

A document database is designed to store semistructured data as JSON-like documents. These databases help developers build and update applications quickly.

Content management, catalogs, user profiles, generative AI use cases (such as chatbots with Retrieval Augmented Generation, similarity search, recommendation systems, and more)

Amazon DocumentDB (with MongoDB compatibility)

Scale JSON workloads with ease using an enterprise-ready document database service compatible with MongoDB.


Graph Database

Graph databases are for applications that need to navigate and query millions of relationships between highly connected graph datasets with millisecond latency at large scale.

Fraud detection, social networking, recommendation engines, generative AI use cases (such as GraphRAG, enhanced fraud detection, discovery of new answers, and more)

Amazon Neptune

Build applications that work with highly connected datasets using a fast, reliable graph database service.


Wide Column Database

A wide column store is a type of NoSQL database. It uses tables, rows, and columns, but unlike a relational database, the names and format of the columns can vary from row to row in the same table.

High-scale industrial apps for equipment maintenance, fleet management, and route optimization

Amazon Keyspaces

Run your Apache Cassandra workloads on a scalable, highly available, and managed wide column database service.


Time Series Database

Time-series databases efficiently collect, synthesize, and derive insights from data that changes over time and with queries spanning time intervals.

Internet of Things (IoT) applications, DevOps, industrial telemetry

Amazon Timestream

Store and analyze trillions of events per day with a fast, scalable, and serverless time series database service.


Ledger Database

Ledger databases provide a centralized and trusted authority to maintain a scalable, immutable, and cryptographically verifiable record of transactions for every application.

Systems of record, supply chain, registrations, banking transactions

Amazon Quantum Ledger Database (QLDB)

Provide transparent, immutable, cryptographically verifiable transaction logs with a fully managed ledger database service.

Maximize innovation velocity while reducing total cost of ownership

Migrate to the cloud by moving to managed AWS databases

Move to managed databases

Automate the time-consuming tasks of setting up, managing, and scaling databases. Spend more time on application development versus the undifferentiated heavy lifting of provisioning and managing databases on-premises.
Build new applications with purpose-built AWS databases

Build modern apps with purpose-built databases

Choose the database service best fit for the job to help you optimize scale, performance, and costs when designing applications. See how purpose-built databases match up with modern microservices architectures.

Modernize your legacy applications with AWS databases

Break free from legacy databases

Stop working around proprietary standards, punitive pricing terms, and frequent audits. Embrace open-source compatible cloud databases with commercial grade performance, availability, and scale at a fraction of the cost.

Modern applications come with demands that traditional data management approaches can not meet. AWS offers high performance, highly available, scalable, distributed database solutions that consist of Purpose-Built Services, AWS Solutions, Partner Solutions, and Guidance to power your modern high performance applications.

Database Migration

Accelerate and support your migration from legacy systems to the cloud with tools built to help streamline data transfer, increase processing performance, and simplify connections between your databases and applications.

High Performance Databases

Build modern applications that need high performance, highly available, scalable databases.

Samsung migrated 1.1 billion users across three continents from Oracle to Amazon Aurora.

"The scalability of Amazon Aurora is the best benefit—especially if we focus on the cost. Samsung reduced monthly database costs by 44%."
