Positive experiences with database services, with minor room for feature enhancements observed
I don't really see any disadvantages of Amazon RDS. With Oracle, I think AWS doesn't provide the RAC stability. If you have Oracle installed in your own data centers, you can set up various clusters and we can set up the RACs, but in Amazon RDS, we cannot have the RAC feature of Oracle. They could add that feature. Amazon RDS has limitations regarding RAC. If we talk about installing Oracle in RDS, we cannot have the RAC, but if you deploy Oracle on GCP, then there is probably the RAC feature available. I observed that around two or three years back, but I'm not sure whether they have added the RAC feature in AWS. Amazon RDS is expensive compared to GCP. GCP also has the same features, and although it is quite extensive and feature-rich, I see Amazon RDS as slightly expensive compared to other clouds.

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

"With RDS, everything is turnkey and always available."
"Amazon RDS handles database backup mechanisms and patch management."
"Amazon RDS makes it easier for me to manage databases compared to traditional databases like MongoDB or local host servers."
"The time to install or set up a database environment is very fast."
"The most valuable feature of Amazon RDS is its performance."
"It makes it easy to administer the database. It helps to scale your database by providing Read Replicas, which reduce transaction time. It is highly available and durable which helps in disaster recovery and management."
"Amazon RDS fulfills PCI requirements, which is a valuable feature for us."
"The most valuable features of Amazon RDS are its scalability, reliability, and intelligence."
"IBM Informix benefits users with high availability and good integration capabilities."
"The solution is quite stable and reliable; we use it mainly due to its general stable nature."
"Replication is a valuable feature and easy to use."
"The scalability is very good."
"My advice is to take it; you will never regret it."
"It supports multiple applications and business intelligence tools."
"Every version is faster than the previous."
"For IoT business cases, having Informix Enterprise Edition work on edge computers, like Raspberry Pi and using Informix replication, makes complex situations simple to build and maintain."
 

Cons

"They should add a feature for manual SQL patching in RDS."
"I would like to see improvements in the tool's automatic restart."
"The solution's connectivity and response logs could be improved."
"It would be helpful if they made it easier to migrate from an existing on-premises solution to the cloud-based service."
"The solution could improve the administration tools."
"Perhaps more platforms in terms of database engine versions would be beneficial."
"In the next release, it would be great to see RDS provide connection pooling out of the box."
"When you are using it for the first time, it is a little bit hard to configure. The first-time configuration is not very easy. It should be easier to configure. Its installation should also be simpler. Currently, its installation is very complex. With SQL Server, we have access to the SQL Server analysis services and reporting services, but such services are not available with Amazon RDS."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"The solution doesn't include functionality like data anonymization."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"This solution is in need of more current tools."
"The solution should offer replication. It would be helpful if the solution would allow us to access third-party tools."
"Informix is very sturdy, but the problem for us is the marketing action around Informix."
"The pricing is a bit expensive."
"This product could be made easier to use for beginners."
 

Pricing and Cost Advice

"The cost is manageable because you can see the expense associated with each instance and utilize tools for tagging and cost control."
"The prices for different regions are different."
"The platform pricing is on the higher side, but given its capabilities and ease of use, it remains competitive."

"Amazon RDS is an expensive solution."
"The pricing of RDS is a little bit high compared to Microsoft... However, it is a good price compared to other solutions."
"Amazon RDS could improve by reducing the price."

"The product has reasonable pricing. We purchase its yearly license."
"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."
"For me, it's always too expensive."
