• Amazon Relational Database Service (RDS)
• AWS Database Migration Service
• Amazon ElastiCache
• Amazon Redshift
• Amazon DynamoDB

Amazon Relational Database Service
• Managed service for MySQL, Oracle, Microsoft SQL
Server, PostgreSQL, and Amazon Aurora
• Handles time-consuming database management tasks,
such as backups, patch management, and replication
• MySQL, PostgreSQL, and Amazon Aurora support one
or more read replicas
• Works with existing code, applications, and tools

Amazon RDS Multi-AZ

Amazon RDS for Aurora
• Amazon Aurora is a MySQL-compatible
relational database engine
– The speed and availability of high-end commercial databases
– The simplicity and cost-effectiveness of open source databases
• Up to five times better performance than MySQL
• At a price point 1/10 of a commercial database
• Amazon RDS for Aurora provides administration
for Aurora by handling routine database tasks

Demo

Details: Amazon RDS for Aurora
• Key Features
– Designed for compatibility with MySQL 5.6.10
– Auto-scaling storage, so no need to pre-allocate
– Data is transparently replicated 6 ways among 3 Availability Zones
– Add up to 15 Replicas
• Single-digit millisecond replica lag times
• Replicas are also Multi-AZ failover candidates
– Encryption at rest and in transit

ü Move data to the same or different database engine
ü Keep your apps running during the migration
ü Start your first migration in 10 minutes or less
ü Replicate within, to, or from Amazon EC2 or RDS
AWS Database
Migration Service

Migrate from Oracle and SQL Server
Move your tables, views, stored procedures,
and data manipulation language (DML) to
MySQL, MariaDB, and Amazon Aurora

Conversion Tool

Amazon ElastiCache
• In-memory managed cache cluster
• Supports two open-source caching engines:
Memcached and Redis
• Automatically detects and replaces failed nodes
• Redis engine supports replication and Multi-AZs
• Great fit for read-heavy applications and often deployed
in front of Amazon RDS

Amazon Redshift
• Fast, fully managed, petabyte-scale relational data
warehouse solution
• Columnar storage technology to improve I/O and
parallelizing queries across multiple nodes (SSD & HDD)
• Uses familiar SQL-based clients and business intelligence
(BI) tools using standard JDBC and ODBC drivers
• Costs less than a tenth of most other cloud data
warehouse solutions: $1,000/TB/Year; starts at $0.25/hour

Amazon DynamoDB
• Fast and flexible NoSQL database service
• Provides a schema-less, no joins, no complex
transactions managed database
• Single-digit millisecond latency at any scale for items
ranging from 1byte to 400KB
• Great fit for mobile, web, games, ad-tech, IoT, and many
other applications

Why NoSQL?
Optimized for storage Optimized for compute
Normalized/relational Denormalized/hierarchical
Ad hoc queries Instantiated views
Scale vertically Scale horizontally
Good for OLAP Built for OLTP at scale
