Featured Reviews

Baqir Sajjad

AWS Architect at Virtual University

Customer support and automated backups offer reliability while ease of deployment enhances user experience

The features of Amazon RDS that I have found most valuable include web and mobile applications, enterprise applications, data warehousing and analytics, and software as a service platforms, along with dev testing environments, disaster recoveries, and backups. The mobile app backend and development environment is also the best feature for database management for my customers. Database management is effective in Amazon RDS because it offers automated backups, high availability, read replicas, and support from multiple database engineers, while also providing security, monitoring and metrics, scalability. We are using snapshots and database migrations as well as performance optimization. The impact of Amazon RDS scalability and backup has been positive, with good vertical scaling, scale up and down, horizontal scaling, and storage scaling. The performance was good and availability helped with reducing downtime.

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.

Have consistently achieved efficient integrations and availability

I am more focused on the leadership side and having the right human plans to make things happen. There are some parts available, but our goal is to move toward a single platform. I would prefer to remain anonymous in discussions. On a scale of 1-10, I rate Oracle Database as a Service a seven.
