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).

Amazon Relational Database Service

  • 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.

Amazon DynamoDB

  • 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.

Amazon ElastiCache

  • 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.

Amazon Neptune
