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.

Has offered a cost-effective option despite frequent technical issues and limited market demand
We find some bugs in IBM Informix. Maybe we are using it more aggressively than others. Every month or every second month, we find some bugs in it, which is not ideal. It should be rare, not this frequent. The good thing is they cover those bugs in the next release within weeks or days on demand. IBM Informix should become hybrid and should include AI features similar to other DBMS systems such as Snowflake, Redshift, and DataBricks. This would help its value rise with the market.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The scalability and cost-effectiveness of AWS were beneficial during spikes in database usage, as it allowed our platform to adjust and remain operational."
"The product's initial setup phase is simple and straightforward."
"The solution is easy to manage."
"The solution reduces the configuration and maintenance of the database."
"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."
"The initial setup is pretty easy."
"This solution has made financial reporting possible by allowing financial people the opportunity to set Informix to "Auto Pilot" so that they can attend other duties."
"Replication is a valuable feature and easy to use."
"The most valuable feature is concurrency and locking because my customers usually use databases in OLTP mode. So, for a large number of competitive users. Other features that are well valued are quick large-scale data types. It is better than Oracle."
"Every version is faster than the previous."
"It supports multiple applications and business intelligence tools."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"So far, we do not have a lot of issues. It's pretty problem-free."
 

Cons

"If our database is too big, we sometimes face glitches in it."
"The tool should include features to clone the RDS instances and have more central management for a lot of RDSs, not just every instance."
"I would like to see some improvements in its version upgrades because its upgrade from MySQL 5.7 to MySQL 8 was not straightforward."
"Areas that could be improved with Amazon RDS on Outposts for Brazilians include the cost because it remains a very important consideration."
"I find the pricing to be expensive."
"Every month or every second month, we find some bugs in it, which is not ideal."
"This product could be made easier to use for beginners."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"In my opinion, the packages could be improved. The version I use doesn't allow for packages. I can do some general procedures, but no packages like in Oracle. So, develop separate modules in SQL language. This would be most beneficial for me."
"The solution lacks some functionality."
"I would like to see backups from secondary servers."
"The solution really doesn't add new features very often."
"The pricing is a bit expensive."
 

Pricing and Cost Advice

"The solution can get expensive fast."
"Amazon RDS on Outposts is expensive compared to other solutions."
"The licenses are included with the subscription my company purchases from Amazon."
"I am not aware of the licensing costs or terms."
"The free edition can be enough to handle moderate-size implementations, but you may want a pay for edition to benefit from more functionality, such as replication."
"The product has reasonable pricing. We purchase its yearly license."
"For me, it's always too expensive."
