AWS RDS vs. Azure SQL Database

September 27, 2021

Introduction

When it comes to cloud hosting, AWS RDS and Azure SQL Database are two popular options. Both are well-established, reliable services that offer many features for companies of all sizes. However, which one is better suited for your needs? In this blog post, we'll compare both options to help you make an informed decision.

Pricing

First and foremost, pricing is an essential factor to consider. While both services offer a range of pricing options, Azure SQL Database generally costs less than AWS RDS.

For instance, for a basic SQL database configuration, AWS RDS charges $0.085 per hour, whereas Azure SQL Database charges $0.05 per hour. Furthermore, it is important to note that AWS charges for traffic separately, whereas Azure does not. So, if you have a high-traffic database, Azure SQL Database could be the better choice.

Overall, pricing can vary widely depending on the specific requirements of your business, so be sure to do your research and compare options.

Features

When it comes to features, AWS RDS has a slight advantage over Azure SQL Database. AWS RDS offers advanced features like automated backups, data replication, and data encryption. RDS also allows integration with other AWS services, like Elastic Load Balancing for scalability.

Additionally, AWS RDS offers support for multiple database engines, including PostgreSQL, MySQL, and Oracle. Whereas Azure SQL Database only supports Microsoft SQL Server.

That being said, Azure SQL Database offers built-in AI capabilities, making it an attractive option for those needing machine learning and AI solutions.

Performance

Both AWS RDS and Azure SQL Database are known for their reliability and performance. However, AWS RDS is often considered to have the edge in terms of speed and scalability.

In benchmark tests, AWS RDS has consistently performed better than Azure SQL Database. On average, AWS RDS had up to 3x faster response times, with higher throughput performance.

However, it is important to note that performance can vary depending on individual configurations, so be sure to test your own configurations for accuracy.

Conclusion

In conclusion, AWS RDS and Azure SQL Database are both great options for cloud hosting. If cost is a primary concern, Azure SQL Database is generally the cheaper option. However, if you need advanced features like data replication, data encryption, and support for multiple database engines, AWS RDS is a better choice.

In terms of performance, AWS RDS is generally faster and has higher throughput performance. However, both services are reliable and offer excellent scalability options.

At the end of the day, the best choice for your business depends on your specific needs and budget.
