Budget is one of the major factors which affects the demand of an application, and Amazon Aurora keeps a complete check on it by charging its users only for the storage and services used. Also, it uses various techniques, which makes it easier to optimize operating costs.

Amazon Aurora Architecture

The Amazon Aurora architecture focuses on reusing the components, which makes its architecture efficient and faster. Amazon Aurora reuses major working systems like recovery, transaction, and query execution, which saves the memory and makes the system efficient. This method and architecture save both storage and time, resulting in enhanced and efficient output. Some new improvements have made Amazon Aurora even better, and they are listed below.

  • Uses virtual storage and creates various data clones to ensure safe backups.
  • Storing changelog on remote disk and prioritizing data accessibility restrictions.
  • Using primary-replica setup.

MySQL Compatibility on Amazon Aurora

MySQL 5.6 and MySQL 5.7 are versions of MySQL, which are compatible with Amazon Aurora and ensure top-notch services. Aurora is compatible with the InnoDB storage engine and does not work with MyISAM. So if you have your data stored in MyISAM, then you need to transfer it to InnoDB.

PostgreSQL Compatibility on Amazon Aurora

AWS Aurora PostgreSQL is compatible with versions PostgreSQL 9.6 and PostgreSQL 10. It is extremely easy to set up PostgreSQL with Aurora as it can increase the throughput and efficiency of operations performed on the database. A PostgreSQL compatible Aurora instance can be launched from the Amazon RDS console and then PostgreSQL can be used as an edition and Amazon Aurora as the engine.

Benefits of Amazon Aurora

A certain question is supposed to hit you: why do I need Amazon Aurora, and what benefits will it bring me? So here are some benefits of Amazon Aurora, which will make it the best pick for a business.

1. Cost-Effective

The crucial part of a business is making profits and optimizing expenses, and Aurora does it for you as you only need to pay for the storage and services used by your system. And the user can make monthly payments for the same.

2. Security

  • Amazon Aurora uses 256-bit data transfer encryption, which helps users transfer data via a secure medium.
  • It uses virtual storage, which makes it easily accessible and restricts access to limited members. 
  • Users can create personalized encryption keys which safeguard sensitive data.

3. Durability

  • Users can create multiple replicas of their data which are restored in case of database failure.
  • It is a global database that makes it easier to access data and further make changes based on the access provided.

4. Migration Support

Aurora makes it easier to migrate local databases by using simple dump commands. 

5. Scalability

Amazon Aurora is equipped with dynamic scaling features that automatically increase or decrease storage based on the requirements.

6. Management

  • One button working makes Aurora extremely easy to manage; you can call an API in your code or make a call on the RDS console.
  • Users can manage their Amazon Cloudwatch with no additional charges included.
  • Auto-update feature allows the system to patch in with the latest updates on the software and fix the latest bugs faced by the user.

AWS Aurora DB cluster

 A volume cluster and one or more Database instances constitute a Database cluster. A cluster volume is a virtual storage section that spans through cells stored(availability zones) in Database Cluster.

There are two types of Aurora DB Cluster formed in combination with various kinds of Database instances.

1. Primary DB instance

This instance supports data input and is responsible for all modifications made to the data volume. There is always at least one Primary DB instance in a DB cluster.

2. Aurora Replica

It connects to the same storage as a DB instance, but it increases the availability of data volumes by locating in various availability zones. In case of Database failure, Aurora replica replaces the data and ensures that operations are continued. Also, it connects to the cache memory and reloads the operations in process and active screens.

Users can set up to 15 aurora replicas in their cluster volumes.

Amazon Aurora Pricing

The pricing of Aurora depends on the usage, so there are special rates for each service, and also you can visit the AWS calculator to find your estimate based on use. Amazon Aurora is billed on the storage used by the user and the total number of operations performed. The data storage is billed on rates of per GB whereas the operations are billed on a per million basis.

There is no upfront cost whereas there can be some extra charges for some features like Backtrack, Snapshot Export, data transfer out of Aurora and Global Database.The prices are compatible for both MySQL and PostgreSQL.

On Demand Instance Pricing

This is probably the best feature of this application that it does not ask you to bill annually or look for long term plans, you have to pay only for the used capacity. This is very useful if you want Aurora for a short project or test, so pay on what you use.

The billing is done based on the per DB instance hour consumed , until the instance is removed or stopped.

Database Storage and Input Outputs Pricing

The users are billed on the basis of Storage used by them at a rate of per GB and they are billed monthly and as per number of operations they are billed on per million requests. The charges for  I/Os depend on the workload and the database engine.

Storage rate    $0.10/GB per month

I/Os                   $0.20/million requests
