AICE Graduate at alx_africa
The installation of Amazon RDS is quite easy and quite scalable.
Director Software Engineer at a computer software company with 10,001+ employees
Despite being a strong feature, scalability could be improved due to the lack of full functionality in autoscaling.
VP engineering at a computer software company with 1,001-5,000 employees
It can be scaled vertically or horizontally so that data insertions and data access are much faster and more secure compared to how Oracle or other databases work.

Enabling performance insights to view query formats where the bottlenecks occur, identifying the fixes, slow queries, and missing indexes.
AWS Architect at Virtual University
Understanding the basic structure of the database, how logs or log shipping happens, how clustering works, how logs are written, where all information is stored, and how it needs to be taken care of are all critical pieces of information.
Founder, Director at perfTech Solutions Pvt Ltd
It might be slightly slower than other database vendors, but it works well since banks typically do not move quickly with leading-edge technology.
Associate Director, Data Architecture at a financial services firm with 10,001+ employees
 

Setup Cost

Amazon RDS pricing offers flexibility and savings, but requires careful cost management to avoid unexpected charges and manage expenses.

Valuable Features

Amazon RDS offers scalability, security, and ease of use with features like automated backups and high availability for diverse applications.
IBM Db2 Database offers powerful SQL, robust security, high performance, scalability, user-friendly interface, and compatibility with IBM products.
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.

Database management is effective in Amazon RDS because it offers automated backups, high availability, read replicas, and support from multiple database engineers, while also providing security, monitoring and metrics, scalability.
AWS Architect at Virtual University
In some cases, we are using the read replica feature, and it does improve our application performance because we do not allow any downstream system to come to the main storage or main databases and perform a query.
Director Software Engineer at a computer software company with 10,001+ employees
All compliance-related aspects have been taken care of from the database point of view, including database encryption and security-related features.

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.

Database has secured high-volume transactions and supports fast, compliant workflow processing
Sterling B2B Integrator is a highly transactional-oriented application, which can be described as an OLTP application. Any data that flows through the application is stored in the database for each step that it performs. IBM Db2 Database helps the application work much faster from an OLTP perspective. IBM Db2 Database is SSL enabled, which means that from the security point of view, any access to the database is through SSL. Additionally, all compliance-related aspects have been taken care of from the database point of view, including database encryption and security-related features. It is highly scalable, and its performance related to database pruning is very good. It can be scaled vertically or horizontally so that data insertions and data access are much faster and more secure compared to how Oracle or other databases work.
