aws aurora pricing 101: aws aurora vs rds pricing​?

This vid explains aws aurora pricing.

i. Amazon Aurora and Amazon RDS (Relational Database Service) are both managed database services provided by AWS, but they have different pricing models and features. Here's a comparison of AWS Aurora vs. RDS pricing:

1. **Amazon Aurora**:
Amazon Aurora is a MySQL and PostgreSQL-compatible relational database built for the cloud, offering high performance, scalability, and durability.
Aurora pricing is based on the instance type and storage capacity you choose.
Aurora offers two types of instances: Aurora DB instances and Aurora Serverless. With Aurora DB instances, you pay for the provisioned compute capacity (similar to EC2 instances). With Aurora Serverless, you pay for the vCPU and memory capacity used by your database, as well as the storage capacity.
Storage costs for Aurora are based on the amount of storage provisioned and consumed by your database.
Aurora also offers features like read replicas and multi-region replication, which may incur additional costs.

2. **Amazon RDS**:
Amazon RDS is a fully managed relational database service that supports multiple database engines, including MySQL, PostgreSQL, SQL Server, Oracle, and MariaDB.
RDS pricing is based on several factors, including the database engine, instance type, storage type, storage capacity, and data transfer.
With RDS, you pay for the provisioned compute capacity (similar to EC2 instances) and storage capacity of your database instances.
RDS offers different pricing options, including On-Demand Instances, Reserved Instances, and Spot Instances, which offer different pricing models and cost-saving opportunities.
Like Aurora, RDS also offers features like read replicas, Multi-AZ deployments, and automated backups, which may incur additional costs.

In general, Aurora tends to be more expensive than RDS for comparable instance types and storage capacities due to its higher performance and additional features. However, Aurora may offer better scalability and cost efficiency for certain workloads, especially those requiring high availability and performance.

When comparing Aurora vs. RDS pricing, it's essential to consider your specific requirements, such as performance, scalability, durability, and budget constraints, to choose the best option for your use case. Additionally, regularly monitor your usage and adjust your resources as needed to optimize costs and ensure cost-effectiveness.
