Aurora is a cloud service, which has been built to work in conjunction with MySQL and PostgreSQL.
The Aurora web service works well with Amazon RDS (Relational Database) by combining the features of enterprise and open-source databases over the cloud. The efficient performance and high-availability is adopted from enterprise databases and the cost-effective nature and simple architecture is adopted from open-source databases.
The end result is an efficient service which is 5 folds quicker than standard MySQL database and 3 folds quicker than PostgreSQL database. It provides a distributed, fault-tolerating, continuous backup and auto-recovery feature. It provides the ability to replicate data objects at three different availability zones.
An Aurora database cluster consists of multiple database instances and a cluster volume which helps in managing these data instances. A cluster volume is basically a virtual database storage which is present in multiple availability zones and every zone contains a copy of the database cluster data. There are 2 types of clusters- Primary DB instance, and Aurora Replica.
An endpoint refers to a combination of host name and port which is created when a user connects to an Aurora cluster.
It has features such as serverless configuration, auto-scalable storage, quick responses, customized endpoints for instances, and parallel operations for certain input output operations. It provides scaling so that the database instance can be modified for every instance in the cluster. Additional replicas of the data can be created when the amount of user requests increases.
