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

"The product's initial setup phase is totally easy."

"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."

"I use Amazon RDS to store and manage data securely. It helps me retrieve information and gain insights from the data that comes in for my business or specific applications."

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

"The biggest advantage of Amazon RDS, which is basically an AWS service, is that you can customize it."

"The dashboard and performance are the most valuable features of Amazon RDS."

"It is very easy to set up initially."

"The most valuable aspect of Amazon RDS is it is on the cloud."

More Amazon RDS pros

"It is a very scalable solution."

"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."

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

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

Cons

"The setup might be a bit challenging for multi-level applications."

"If Amazon RDS can be provided as a service platform, it would be beneficial for years. Instead of focusing on infrastructure, they can assist backend engineers and those with varying technical expertise in utilizing it effectively. It would be helpful if Amazon could provide a more predictable pricing strategy."

"The Performance Monitor they have is a little clanky, at least in regards to the UI."

"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."

"Amazon RDS could improve by having more sophisticated. I use other solutions that have better technology for more difficult tasks."

"The solution's version upgrade and performance 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."

"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."

More Amazon RDS cons

"The tool needs to improve horizontal scaling."

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

"The tool lacks to offer AI features."

"The cost can be a bit high."

"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."

Pricing and Cost Advice

"Amazon RDS is an expensive solution."

"The solution's price is good."

"The cost is manageable because you can see the expense associated with each instance and utilize tools for tagging and cost control."

"The price of Amazon RDS is expensive."

"The substantial initial credit and cost-effectiveness make Amazon an attractive option."

"The solution is fairly priced."

"The cost depends on the kind of instance we use."

"The price of Amazon RDS is reasonable."

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.
