Databases

Amazon Aurora

Aurora is a MySQL and PostgreSQL compatible relational database engine that combines the speed and availability of high-end commercial databases.
Aurora is up to five times faster than standard MySQL databases and three times faster than standard PostgreSQL databases.
It provides the security, availability, and reliability of commercial databases at 1/10th the cost.
Aurora is fully managed by Relational Database Service (RDS).
Aurora features a distributed, fault-tolerant, self-healing storage system that auto-scales up to 64TB per database instance.
It delivers high performance and availability with up to 15 low-latency read replicas, point-in-time recovery, continuous backup to S3, and replication across three Availability Zones (AZs).

RDS makes it easy to set up, operate, and scale a relational database in the cloud.
It provides cost-efficient and resizable capacity while automating time-consuming administration tasks such as hardware provisioning, database setup, patching and backups.
RDS is available on several database instance types - optimized for memory, performance or I/O - and provides you with six familiar database engines to choose from, including Aurora, PostgreSQL, MySQL, MariaDB, Oracle Database, and SQL Server.
You can use the Database Migration Service to easily migrate or replicate your existing databases to RDS.

DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale.
It's a fully managed, multiregional, multi-master database with built-in security, backup and restore, and in-memory caching for internet-scale applications.
DynamoDB can handle more than 10 trillion requests per day and support peaks of more than 20 million requests per second.

ElastiCache is a web service that makes it easy to deploy, operate, and scale an in-memory cache in the cloud.
The service improves the performance of web applications by allowing you to retrieve information from fast, managed, in-memory caches, instead of relying entirely on slower disk-based databases.
ElastiCache supports two open-source in-memory caching engines:
- Redis:
  - A fast, open source, in-memory data store and cache.
  - It has many features like backups and restores.
  - It has Multi-AZ and read replicas.
  - Has data persistence.
- Memcached:
  - A widely adopted memory object caching system.
  - It is just a pure cache.
  - It has no backups and restores.
  - No data persistence.

Neptune is a fast, reliable, fully-managed graph database service that makes it easy to build and run applications that work with highly connected datasets.
The core of Neptune is a purpose-built, high-performance graph database engine optimized for storing billions of relationships and querying the graph with milliseconds latency.

DocumentDB is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads.

S3 is an object storage service that offers industry-leading scalability, data availability, security, and performance.
Amazon S3 is designed for 99.999999999% (11 9's) of durability, and stores data for millions of applications for companies all around the world.
