The most valuable features of MongoDB Atlas in handling large data volumes include collection size and its NoSQL database capabilities.

Dhiraj Verma

General Manager at Kaleyra

For more quotes and insights, download the MongoDB Atlas report

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.

reviewer2787105

Manager - Production Database Administration at a tech vendor with 10,001+ employees

The feature I find most valuable in SQL Server is Query Store, especially for production performance troubleshooting, as it provides a historical view of query execution, duration, CPU, I/O, and the execution plan, allowing me to compare current performance with previous behavior.

Shakti Gupta

SQL server database administrator 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.

Developers have benefited from flexibility and performance but pricing has needed further attention

I am only familiar with databases and applications. I am from the development team and I am a user of database and cloud but I don't know the infrastructure. As a user, I deal with the Oracle Database. I know the organization has a license with the product. We don't utilize real-time analytics with MongoDB Atlas. I don't use MongoDB Atlas directly, so I don't know how it can be improved. I would place MongoDB Atlas at a medium level. I would rate it at a six or seven. I believe MongoDB Atlas can improve a little. My overall review rating for this product is six out of ten.

Hybrid data platform has strengthened performance, security, and incident response for production

SQL Server is very mature, but I see areas for improvement, especially in performance tuning, troubleshooting, and automation. Although tools such as Query Store and dynamic management views are powerful, some troubleshooting tasks still require senior SQL Server database administrator expertise. It would be valuable to have more intelligent, built-in recommendations for root cause analysis, indexing, blocking, and query optimization. I would also like to see simplified and consistent management across on-premises SQL Server and Azure SQL services, as managing hybrid environments sometimes requires different tools and approaches. Finally, improved patching, updates, monitoring, and cost and license transparency could make SQL Server easier to manage at the enterprise scale. One area I would improve in SQL Server is its documentation and troubleshooting guidance. SQL Server documentation is comprehensive, but for complex production issues, I would like to see more real-world troubleshooting examples, especially for scenarios such as Always On synchronization issues, blocking and deadlocks, performance degradation, and upgrade features.
