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.

Efficiently handles high-traffic scenarios and compatible with PostgreSQL extensions, offering flexibility in database management

There are many areas of improvement , especially in terms of DDL query routing. Even though it's masterless, DDL queries need to be sent to the coordinator node. Also, setting up a multi-node environment could be more straightforward. Currently, setting up a multi-node environment is challenging. It's a bit tricky. Installation on each PostgreSQL node can lead to communication issues between nodes. An automatic rebalancing feature would be a significant improvement. Currently, I have to manually command the rebalance. It would be more convenient if it was rebalanced automatically. The dashboard and monitoring capabilities are good, but it would be helpful to have an integrated availability dashboard.

Quotes from Members

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

Pros

"The scalability is the best, and I have no issues with the ability to scale."

"It significantly reduces database management overhead."

"The product solved our DevOps and admin problems."

"Amazon RDS is good for backups, auto-scanning, and disaster recovery. It's also appropriate for the office server."

"The IT is easy to set up, which is the best."

"It handles large-scale data migrations perfectly. Amazon RDS's performance is quite good. Charges are incurred after you utilize the service"

"It is very easy to set up initially."

"The provisioning is much faster. You don't have to prepare hardware or install software. You just need to create an instance and you have a database."

More Amazon RDS pros

"You can use Citus Data to write complex scripts. I like its version upgrades and disaster recovery as well."

"It's very straightforward to implement the solution. It took us two days to set up everything."

"Its distributed processing capabilities are a standout feature. It requires minimal changes to get up and running if you already have a system on PostgreSQL. Citus can run in its natural state."

Cons

"With my limited experience, I have noticed that documentation management could be improved. It could be better."

"Technical support could be better."

"There are some advanced monitoring queries that we cannot execute because Amazon doesn't give admin privileges to the end users."

"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."

"The product should support new databases."

"The Amazon RDS engine could provide features for additional databases, such as Db2. It could also provide support for other databases, such as NoSQL databases, DynamoDB, and Apache Cassandra. They could all stay under one hood."

"One of the challenges of AWS RDS is that it doesn't support performance insight. So we need to write our own script or use third-party tools."

"For improvements, Amazon RDS could work on more features for multi-availability zone deployment to enhance higher availability, and on simplifying migration for those transitioning from on-premises to cloud environments."

More Amazon RDS cons

"Citus Data needs to improve its stability. Do not consider this product if you have the budget. It is still developing and has a lot of issues."

"There are many areas of improvement , especially in terms of DDL query routing. Even though it's masterless, DDL queries need to be sent to the coordinator node. Also, setting up a multi-node environment could be more straightforward."

"More features in monitoring and the reporting could make it better."

Pricing and Cost Advice

"Amazon RDS is an expensive solution."

"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."

"The pricing of RDS is a little bit high compared to Microsoft... However, it is a good price compared to other solutions."

"Amazon RDS is cheaper compared to other tools."

"The price could be better."

"Amazon RDS is less expensive than other solutions."

"We are paying for a service license."
