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.

Infrastructuer Security at Premise Data
A stable and scalable relational database that ensures a return on investment for its users
The most valuable feature of the solution is its scalability. Scalability comes with two options, among which Google Cloud Spanner can scale horizontally, compared to other relational databases that scale vertically. You can change Google Cloud Spanner's resource configuration, which is done through processing units. Suppose you set up Google Cloud Spanner initially with a hundred processing units, and then you run out of resources since your database used too much CPU. In the aforementioned scenario, you can scale up or down and face no downtime in the production phase. The solution's features are important when running a company twenty-four hours, seven days a week.

Quotes from Members

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

Pros

"Encryption is the most valuable feature."
"The product's most valuable features are option groups, S3 integration, automated and scheduled snapshots, and cross-region replication."
"The solution has unique features like backup and recovery, and snapshots. It upgrades automatically. The solution offers easy analytics concerning performance metrics. Its reliability and scalability are very good. The tool's most valuable features are disaster recovery, high availability and scalability."
"The initial setup is straightforward, and technical support is good."
"Amazon RDS is easy to maintain and easy to deploy."
"I use Amazon RDS to support scalability, with multi-AZ support being an essential aspect."
"It is very easy to set up initially."
"The tool is very easy to use and configure."
"It is a very scalable solution."
"Google Cloud Spanner is stable."
"The application deployment in the cloud is the best feature of the infrastructure."
"We can scale the solution if we need to."
"The most valuable feature of the solution is its scalability. Scalability comes with two options, among which Google Cloud Spanner can scale horizontally, compared to other relational databases that scale vertically."
"The solution is stable and reliable."
 

Cons

"Some features are disabled, like running "alter system/database". There are Amazon alternatives, but it is not transparent to the application."
"The running cost could be improved."
"You can only get access from the sales support. That means if you want to buy something or renew your subscription or upgrade, all these services are easily available. Yet, if you would like to get some technical support, you have to pay for it. You have to pay for an additional subscription."
"The backup and restore processes take more time compared to other providers. For instance, if DigitalOcean takes two minutes to restore or create a backup, AWS will take 2 to 3 minutes."
"Need to have in depth understanding of cost, else we are in position to pay more, which makes us think our own DB is better when cost is very huge amount."
"Some of the features will not be there. For example, some on-premises things we want to set up will not be supported there. There are some challenges that they are fixing."
"In the next release, it would be great to see RDS provide connection pooling out of the box."
"There are some advanced monitoring queries that we cannot execute because Amazon doesn't give admin privileges to the end users."
"The cost can be a bit high."
"The tool lacks to offer AI features."
"Google came up with something called Cloud Spanner Emulator, which fails to work like the real product if I want to develop some code and run a database locally on my machine."
"I want to improve the deployment of cameras and surveillance infrastructure."
"The tool needs to improve horizontal scaling."
 

Pricing and Cost Advice

"The prices for different regions are different."
"On a scale from one to ten, where ten is the most expensive, and one is the cheapest, I rate the solution's pricing a seven out of ten."
"The pricing of RDS is a little bit high compared to Microsoft... However, it is a good price compared to other solutions."
"The solution is expensive."
"The cost is manageable because you can see the expense associated with each instance and utilize tools for tagging and cost control."
"The solution's pricing needs improvement."
"Amazon RDS is not a very expensive solution."
"The product is expensive."
"Price-wise, I heard that Google Cloud Spanner is on the higher side."
"It is expensive."
