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.

Offers good performance to users

The tool lacks to offer AI features. In the future, I would like the product to offer AI features to users. Nowadays, we are creating small acronyms for our SQL Server. We put some templates. If I just put your name and stop it, the entire cloud can be explored, but such features are not there in Google Cloud Spanner. As a layman rather than a developer, if I create a tool or a procedure. If I write a procedure and then when you describe a procedure, a dummy procedure will be written for you, and it will be available for you as a template in SQL Server, but such kind features are not there in Google Cloud Spanner.

Quotes from Members

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

Pros

"It is very easy to set up initially."

"It is easy to use, flexible, and powerful."

"Amazon RDS is quite a well-managed and stable service...The initial setup was very easy."

"The solution is good for on-premise deployments."

"Based on my experience, I would rate this solution a nine out of ten."

"Amazon RDS provides data encryption using services like KMS, crucial for securing high-sensitive data and meeting compliance requirements such as HIPAA or PCI DSS."

"The product solved our DevOps and admin problems."

"Encryption is the most valuable feature."

More Amazon RDS pros

"The application deployment in the cloud is the best feature of the infrastructure."

"Google Cloud Spanner is stable."

"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."

"It is a very scalable solution."

"We can scale the solution if we need to."

Cons

"Amazon RDS should have a more user-friendly graphical user interface and include better database management options."

"Sometimes the interface has many moving parts, which is a concern."

"The security features could be improved."

"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."

"Technical support could be better."

"It would be helpful if they made it easier to migrate from an existing on-premises solution to the cloud-based service."

"The product should support new databases."

"One notable improvement that could enhance the database management experience, particularly during migration scenarios, is the accessibility of the root user."

More Amazon RDS cons

"The tool needs to improve horizontal scaling."

"I want to improve the deployment of cameras and surveillance infrastructure."

"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."

"The cost can be a bit high."

"The tool lacks to offer AI features."

Pricing and Cost Advice

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

"AWS is becoming pretty expensive because cheap or absolutely free services have become paid services. Amazon RDS is not an expensive product, but Amazon's ecosystem is becoming increasingly expensive."

"Amazon RDS could improve by reducing the price."

"Licensing fees are paid on an annual basis."

"Amazon RDS is less expensive than other solutions."

"In my case, MySQL is free, and if there are any costs, then it is much less than other solutions since all such things usually come bundled with the hardware."

"The solution is expensive."

"The solution's pricing needs improvement."

Overview

Amazon Relational Database Service (Amazon RDS) is a web service that makes it easier to set up, operate, and scale a relational database in the cloud. It provides cost-efficient, resizeable capacity for an industry-standard relational database and manages common database administration tasks.

Amazon Web Services (AWS)

Cloud Spanner is the first and only relational database service that is both strongly consistent and horizontally scalable. With Cloud Spanner you enjoy all the traditional benefits of a relational database: ACID transactions, relational schemas (and schema changes without downtime), SQL queries, high performance, and high availability. But unlike any other relational database service, Cloud Spanner scales horizontally, to hundreds or thousands of servers, so it can handle the highest of transactional workloads. With automatic scaling, synchronous data replication, and node redundancy, Cloud Spanner delivers up to 99.999% (five 9s) of availability for your mission critical applications. In fact, Google’s internal Spanner service has been handling millions of queries per second from many Google services for years.
