This scalability is critical as it allows for runtime expansion, which is essential for businesses moving from on-premises to the cloud.

The server where we installed it has grown from 64 gigabytes in RAM to 256 gigabytes, demonstrating significant scalability capabilities.
Subdirector of Support for Production at Servicios Electrónicos Globales -Oficial

All applications supporting SQL Server in my experience work very well across various industries including telecom, finance, banking, ad, entertainment, and workforce management.
Manager - Production Database Administration at a tech vendor with 10,001+ employees
 

Room For Improvement

Amazon Aurora users seek better pricing, expanded support, smoother migrations, and improvements in performance, scalability, and developer resources.
SQL Server faces criticism for requiring Internet Explorer, high licensing costs, complex operations, and lacking scalability and compatibility.
There are technical challenges, such as the inability to provision the database using a PostgreSQL snapshot directly.
Digital Services & Engagement Senior Manager at AXA
Keeping extensions up-to-date with PostgreSQL releases would enhance Aurora's functionality.
Associate Vice President - Database Management (Principal Solutions Architect) at Northbay
I used the backup options in Amazon Aurora for cloning databases. It's very common.
Data & Solution Archtect at Enkel
It is fine to do a first release that works, but you cannot simply abandon it in the following years without service packs and improvements.
Data Warehouse Lead at Resurs Bank AB (publ.)
I would appreciate using Microsoft Pro as it can integrate with Excel or, with a simple query, consume information from the database using Microsoft Excel.
Infrastructure Coordinator at a financial services firm with 10,001+ employees
When we consider the price for replication in another site, the pricing becomes prohibitive.
Subdirector of Support for Production at Servicios Electrónicos Globales -Oficial
 

Setup Cost

Amazon Aurora provides flexible, cost-effective pricing with notable performance benefits, though some consider it expensive compared to self-managed solutions.
SQL Server offers high initial costs but delivers value in features, scalability, and ROI, and is cheaper than Oracle.
The pricing is reasonable and not overly expensive.

Amazon Aurora is not very expensive as other solutions with similar features from other vendors come at almost the same cost.
Associate Vice President - Database Management (Principal Solutions Architect) at Northbay
The pricing for Amazon Aurora is different from DocumentDB because DocumentDB is cheaper.
Data & Solution Archtect at Enkel
Cost savings on human resources for Windows plus SQL Server versus other solutions.

Valuable Features

Amazon Aurora offers automated maintenance, high scalability, and compatibility, ideal for diverse databases and efficient FinOps management.
SQL Server offers robust features, ease of use, and reliability, ideal for organizations needing effective database management and optimization.
Amazon Aurora offers a 99.9% SLA compared to PostgreSQL. This ensures a high level of availability for our applications.
Digital Services & Engagement Senior Manager at AXA
It replicates data across multiple Availability Zones, ensuring high availability and geographical redundancy, which can be considered a GR instead of a DR.
Associate Vice President - Database Management (Principal Solutions Architect) at Northbay
Always On HADR functionality is one of the features that I use on a daily basis and one of my most used features, saving me lots of time, especially since previously I had to build a SQL cluster and Windows clusters that had many dependencies on shared infrastructure, but now with Always On, it is too stable with easy management and almost zero maintenance, which SQL Server handles itself.
Manager - Production Database Administration at a tech vendor with 10,001+ employees
I have been working with SQL Server for a long time, and it works well for me as I am using it in different applications, such as web applications, Windows applications, or the data warehouse reporting.

High availability and operational efficiency achieved with reliable managed services
We have primarily used Amazon Aurora for handling our databases. We migrated from PostgreSQL to Amazon Aurora about a year ago. It serves as a customized PostgreSQL database that we utilize Amazon Aurora offers a 99.9% SLA compared to PostgreSQL. This ensures a high level of availability for our…
Peter Larsson - PeerSpot reviewer
Data Warehouse Lead at Resurs Bank AB (publ.)
Ledger and seamless integrations have strengthened trusted analytics and unified workloads
SQL Server's high availability and disaster recovery features work for supporting mission-critical applications, but there is much more to wish for. These features are not quite ready yet, although they do function. However, they could be significantly better. High availability and disaster recovery features should be improved in the next releases. I have noticed that everything could be improved or enhanced in the future, particularly temporal tables and window functions. Sometimes, I believe Microsoft releases features to stay ahead of competitors, but they do not make them feature-rich or feature-complete. They release something to be ahead of leaders and then seem to forget to maintain and upgrade them. I want Microsoft to pay more attention and be more mindful about the things they implement. It is fine to do a first release that works, but you cannot simply abandon it in the following years without service packs and improvements. You must continue to build on features rather than forgetting about them.
