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

"Relational databases excel in extensive normalization, eliminating data redundancy and efficiently structuring tables which leads to a clear and efficient relationship between tables using primary keys."
"Amazon RDS fulfills PCI requirements, which is a valuable feature for us."
"The product's installation phase is easy."
"It handles large-scale data migrations perfectly. Amazon RDS's performance is quite good. Charges are incurred after you utilize the service"
"Amazon RDS is easy to maintain and easy to deploy."
"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 initial setup is straightforward, and technical support is good."
"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 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."
"It is a very scalable solution."
"We can scale the solution if we need to."
"Google Cloud Spanner is stable."
 

Cons

"Currently, we are using Fargate. Instead of that, we are planning to use EC2 instances, but we are facing some problems, and we are unable to enable NAT gateway for Elastic Load Balancer. When we enable auto-scaling, the instance count increases, and we get IP addresses dynamically. We need to whitelist the IPs of these instances, but there is no option to whitelist those IPs in Amazon RDS. We need one static IP that we can assign to ELB so that we can whitelist this IP."
"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."
"I would like to see improvements in the tool's automatic restart."
"There are some advanced monitoring queries that we cannot execute because Amazon doesn't give admin privileges to the end users."
"The security features could be improved."
"There are some use cases that might come up where we would want to understand the performance aspects better."
"When you are using it for the first time, it is a little bit hard to configure. The first-time configuration is not very easy. It should be easier to configure. Its installation should also be simpler. Currently, its installation is very complex. With SQL Server, we have access to the SQL Server analysis services and reporting services, but such services are not available with Amazon RDS."
"Amazon cannot guarantee the stability of some extensions, and there is a need for different extensions to meet PCI requirements."
"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."
"I want to improve the deployment of cameras and surveillance infrastructure."
"The tool lacks to offer AI features."
"The tool needs to improve horizontal scaling."
 

Pricing and Cost Advice

"The substantial initial credit and cost-effectiveness make Amazon an attractive option."
"The solution's pricing needs improvement."
"The platform pricing is on the higher side, but given its capabilities and ease of use, it remains competitive."
"Amazon RDS is cheaper compared to other tools."
"The solution is expensive."
"The cost of using this solution is similar to that of having your own data center."
"By using a combination of Reserve Instances and On-Demand pricing, you can reduce the cost."
"The price of Amazon RDS is expensive."
"Google Cloud Spanner is an expensive solution."

"It is expensive."
"Price-wise, I heard that Google Cloud Spanner is on the higher side."
