Ensure high availability with robust encryption and seamless backups
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 best practices we've employed with RDS help design a well-architected framework, encompassing security, encryption, scalability with multi-availability zone deployment, and operational excellence with automated backups. RDS features, such as reserved instances, storage auto-scaling, monitoring with technologies like CloudWatch, and proxies, contribute to cost optimization. The solution enhances security with IAM authentication and offers high availability to end users.
Ethan Lo - PeerSpot reviewer
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

"It's a fully managed database, so that makes our life easier from the operational standpoint. That is the key, basically."
"The product is very, very easy to use."
"Amazon RDS handles database backup mechanisms and patch management."
"One of the most valuable features is that it is serverless, so we don't have to worry about scaling."
"I use Amazon RDS to support scalability, with multi-AZ support being an essential aspect."
"The most valuable features of the solution stem from the fact that it requires an easy setup phase, and it is also easy to use while not being too heavy on its users."
"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."
"Amazon RDS is good for backups, auto-scanning, and disaster recovery. It's also appropriate for the office server."
"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."

"Google Cloud Spanner is stable."
 

Cons

"A lot of the features are disabled by default. The solution should enable more features. I understand this could cause challenges to management for many clients using RDS, however."
"It would be better if it integrated seamlessly with Microsoft products. Our clients use the Microsoft Tally application server. We already tried to create a reputation from, for example, an on-premises environment from our client to Amazon RDS using Microsoft Tally server, and we couldn't do that because we didn't have a strong user in RDS. We couldn't create a reputation from an on-premises environment from the Microsoft Tally server to RDS. I think that it would be a good implementation, and it would help us with this case."
"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."
"I also don't think it's very scalable."
"I like using Amazon RDS because it offers quick operations for me. However, there are times when understanding how to use some of the services can be challenging, even with documentation. If I could add a feature, I'd improve navigation for related services."
"The product must add more older versions of the database engines."
"There are some advanced monitoring queries that we cannot execute because Amazon doesn't give admin privileges to the end users."
"With my limited experience, I have noticed that documentation management could be improved. It could be better."
"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."
"The tool needs to improve horizontal scaling."
"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."
