AWS - Database Flashcards
What is RDS?
Relational Database Service (RDS): Provides cost-efficient and resizable capacity while managing time-consuming database administration tasks, freeing you to focus on your applications and business.
Amazon RDS gives you access to several familiar database engines, including Amazon Aurora, MySQL, PostgreSQL, MariaDB, Oracle, and SQL Server. This means that the code, applications, and tools you already use with your existing databases can be used with RDS.
RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period and enabling point-in-time recovery.
What is Aurora?
Aurora: It is an AWS proprietary relational Database that is compatible with MySQL and PostgreSQL. It combines the performance and availability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases.
What is DynamoDB?
It is a nonrelational database i.e a NoSQL DB. It is a managed service, i.e you do not need to tune or manage it in any way, AWS does this for you.
What is ElastiCache?
It offers fully managed Redis and Memcached. Seamlessly deploy, operate, and scale popular open source compatible in-memory data stores.
