Has reduced database management efforts and supported student learning through smooth deployment
The most important feature of Amazon RDS on Outposts for me is the self-managed aspect. The user doesn't have to worry about putting the service online, scaling the solution, and they don't have to worry about backups and other administrative tasks. The self-managed feature by AWS is very interesting. I use the automated backups in Amazon RDS on Outposts, and I recommend it. I work as a consultant for AWS products, and I have recommended Amazon RDS on Outposts and the automatic backup. Automated backups are helpful because the technical team doesn't have to worry about backups, making it much easier. It frees the technical team to deal with other kinds of questions within their projects. Amazon RDS on Outposts positively impacted my organization by being very useful to migrate, freeing the technical team to think about other matters instead of focusing just on backups and provisioning the database.

Database has secured high-volume transactions and supports fast, compliant workflow processing
Sterling B2B Integrator is a highly transactional-oriented application, which can be described as an OLTP application. Any data that flows through the application is stored in the database for each step that it performs. IBM Db2 Database helps the application work much faster from an OLTP perspective. IBM Db2 Database is SSL enabled, which means that from the security point of view, any access to the database is through SSL. Additionally, all compliance-related aspects have been taken care of from the database point of view, including database encryption and security-related features. It is highly scalable, and its performance related to database pruning is very good. It can be scaled vertically or horizontally so that data insertions and data access are much faster and more secure compared to how Oracle or other databases work.

"The scalability and cost-effectiveness of AWS were beneficial during spikes in database usage, as it allowed our platform to adjust and remain operational."

"For our clients who have a large scale enterprise, we suggest DB2 and mid-scale enterprise customers we suggest SQL Server or others."
"The most valuable feature is PowerPC support."
"Some of the most valuable features are the scaling from a small very cheap installation to a very large enterprise installation. In addition, the backups and assistance are good."

"I have found the most valuable feature to be its availability."
"The solution is stable, and even if there are a large number of records, the performance stays the same with no bugs or glitches and it doesn't crash or freeze."

"In my limited use case, the only major thing would be improved reporting capability."
"The application development requires a Java developer and not every company has these resources."
