Why is AWS Aurora faster?
Failover time is faster on Aurora This mainly happens because of log buffers. Unlike regular RDS, Aurora does not keep a log buffer on the instances. Instead, Aurora keeps the logs at the storage which is separate from the DB instances. Therefore, during a failover, only the DNS propagation matters.Sep 24, 2019
What is difference between Aurora and Aurora serverless?
Amazon Aurora and Aurora Serverless are two distinct products from AWS. While Amazon's Aurora lets you use cloud-based computing resources to test and run your applications, the Aurora Serverless is a configuration that enables automated capacity scaling and for connecting applications.
Is AWS Aurora cheaper than RDS?
Aurora's unique architecture gives you more durability, scale and resilience. And for many workloads, it's cheaper and faster than running the equivalent RDS database. It's what I'd choose, if I was building a new application today—but it may not be right for you.May 28, 2021
What is AWS Aurora serverless?
Amazon Aurora Serverless is an on-demand, auto-scaling configuration for Amazon Aurora. It automatically starts up, shuts down, and scales capacity up or down based on your application's needs. It enables you to run your database in the cloud without managing any database capacity.
Use cases
Amazon Aurora is a great option for any enterprise application that can use a relational database. Compared to commercial databases, Amazon Aurora can help cut down your database costs by 90% or more while improving reliability and availability of the database.

What is Aurora AWS?
AWS Aurora is a managed database service offering from amazon cloud. This is one of the widely used services for data store for low latency and transactional data storage and processing. The AWS aurora service provides the comprehensive features of open source databases like MySQL and PostgreSQL along with enterprise standard reliability and scalability. It works with a clustered approach with data replication in the AWS availability zone for efficient data availability. It works much faster compared to the native MySQL and PostgreSQL databases with low server maintenance feasibility. It supports high storage capacity which can scale up to 64 Terabytes of database size for enterprise implementation.

Overview of Amazon Aurora global databases
By using an Amazon Aurora global database, you can run your globally distributed applications using a single Aurora database that spans multiple AWS Regions.
Advantages of Amazon Aurora global databases
By using Aurora global databases, you can get the following advantages:
Configuration requirements of an Amazon Aurora global database
An Aurora global database spans at least two AWS Regions. The primary AWS Region supports an Aurora DB cluster that has one writer Aurora DB instance. A secondary AWS Region runs a read-only Aurora DB cluster made up entirely of Aurora Replicas.
Creating an Amazon Aurora global database
In some cases, you might have an existing Aurora provisioned DB cluster running an Aurora database engine that's global-compatible. If so, you can add another AWS Region to it to create your Aurora global database. To do so, see Adding an AWS Region to an Amazon Aurora global database.
Adding an AWS Region to an Amazon Aurora global database
An Aurora global database needs at least one secondary Aurora DB cluster in a different AWS Region than the primary Aurora DB cluster. You can attach up to five secondary DB clusters to your Aurora global database.
Creating a headless Aurora DB cluster in a secondary Region
Although an Aurora global database requires at least one secondary Aurora DB cluster in a different AWS Region than the primary, you can use a headless configuration for the secondary cluster. A headless secondary Aurora DB cluster is one without a DB instance. This type of configuration can lower expenses for an Aurora global database.
Using a snapshot for your Amazon Aurora global database
You can restore a snapshot of an Aurora DB cluster or from an Amazon RDS DB instance to use as the starting point for your Aurora global database. You restore the snapshot and create a new Aurora provisioned DB cluster at the same time. You then add another AWS Region to the restored DB cluster, thus turning it into an Aurora global database.
