Review summaries and opinions

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

ROI

Sentiment score
7.6
Azure Database for PostgreSQL offers significant cost savings and efficiency improvements, reducing ownership costs by eliminating expensive licenses.
Sentiment score
7.2
Oracle Database as a Service offers productivity and security benefits, despite high costs, with strong preference in regions like APAC.
It offers at least 25 percent cost savings compared to maintaining on-premises databases.
Now, we use embedded PostgreSQL vectors, which will undoubtedly reduce the TCO by using a much more cost-effective solution.
We've reduced our total ownership cost because we are not spending on expensive SQL server licenses.
In Bangladesh, digital banking is becoming prominent within a couple of years, so all banking systems will be digital.
 

Customer Service

Sentiment score
7.4
Users praise Microsoft Learn's documentation, benefit from fast support response, and find engineering engagement insightful for urgent issues.
Sentiment score
8.3
Oracle Database support is responsive but needs better communication, efficiency, multilingual resources, and support team segmentation.
Once we open a support case, we have people engaged within about 20 minutes, especially for a Sev 1 issue.
The documentation and training we've received through Microsoft Learn on how to migrate, deploy, and manage the solution is exceptional.
We handle most implementations in-house, without extensive reliance on Microsoft's technical support.
Oracle provides expert support globally, not just in South Asia -- also in Europe and America.
 

Scalability Issues

Sentiment score
7.9
Azure Database for PostgreSQL efficiently scales workloads with FlexServer, offering easy resizing for large enterprises and government projects.
Sentiment score
6.6
Oracle Database as a Service is highly scalable, supporting numerous users and servers, but scaling costs could improve.
However, we can see how well it scales after we deploy it for some large enterprise customers or big government organizations.
The scaling options with FlexServer provide us with the flexibility we need based on application complexity.
We can scale up compute and scale it down, but once storage is allocated, there is no way to scale it back down.
 

Stability Issues

Sentiment score
7.0
Azure Database for PostgreSQL is stable with no latency issues, though it may crash during peak usage without auto-healing.
Sentiment score
7.1
Oracle Database as a Service is praised for its strong stability, reliability, and smooth integration, despite some scalability concerns.
There is a stability issue where, if the database usage peaks quickly, it may crash and require intervention to restore functionality.
We have generative AI applications, and we have not noticed any latency.
Overall, I have not encountered any real latency issues or stability concerns.
The solution is stable, resilient, and doesn't crash under pressure.
 

Room For Improvement

Azure Database for PostgreSQL needs faster scaling, better reliability, extensions, user management, cost efficiency, support, and error detection.
Oracle Database as a Service needs complexity reduction, enhanced integration, improved usability, security, automation, and flexible licensing to boost adoption.
It does not presently support knowledge graph functionalities as Neo4j does.
Azure Database for PostgreSQL can be improved by allowing quicker scaling without blips.
I believe there could be improvements in the mirroring part and Change Data Capture (CDC).
With the advent of generative AI, adding functionality where current administrative activities could be automated would be beneficial.
It would be beneficial if Oracle could offer features similar to those provided by open-source platforms like Postgres, such as a multi-core-based platform and a shared node database.
 

Setup Cost

Enterprise buyers appreciate Azure's cost-efficient, pay-as-you-go pricing for PostgreSQL, reducing on-premises database costs significantly.
Oracle Database as a Service is costly, includes licenses and support, with high technical support quality but added fees.
We've reduced costs by 60 percent compared to maintaining on-premises solutions.
The pay-as-you-go pricing model positively affects database-related costs by allowing us to start small and scale as needed.
The pay-as-you-go model works well for us.
 

Valuable Features

Azure Database for PostgreSQL offers seamless integration, robust networking, efficient AI tools, and strong security with a positive cost-benefit ratio.
Oracle Database as a Service is praised for its multitenancy, scalability, security, analytics, and seamless integration with Oracle applications.
My takeaway as a CTO is that they're comfortable with the security posture, the features, the observability, alerts, and now it integrates into the rest of the Azure landscape.
The query analyzers help me find out what's happening in each of the queries.
The most valuable features of Azure Database for PostgreSQL are its networking capabilities, which allow for integration with other Azure services.
The encryption level, resilience, and secure features from both clients, particularly the resilience aspect of Oracle Database, are highly valuable.
The valuable features include availability, agility, and scalability.

Featured Reviews

Daniel Amini - PeerSpot reviewer
An incredibly powerful industry leader that enabled us to build critical pieces of national infrastructure
Azure Database is simple and easy to use. We followed the prescribed training and upskilled 10 engineers. They think it's straightforward. They've already got PostgreSQL skills to optimize the solution, so they know what to do. It was easy to get started quickly and become effective. My team speaks highly of the platform's observability and monitoring features. It's as efficient as an enterprise needs it to be and. has all of the tooling and telemetry necessary to run an enterprise database. We take security seriously. The team has looked at the security features, and nothing has been flagged to us. My takeaway as a CTO is that they're comfortable with the security posture, the features, the observability, alerts, and now it integrates into the rest of the Azure landscape. The OpenAI integration and extensions have massively simplified integrating AI into a database. PostgreSQL's native vector capabilities are also incredibly powerful.
Duy AnhMai - PeerSpot reviewer
Offers security and good performance
Price-wise, the tool is expensive, and I feel it is an area where improvements are needed. Oracle Database as a Service is not as popular as other tools because we use AWS and GCP. Oracle is okay in terms of performance for banking businesses and some big companies. As I use the tool in Heineken, I know Oracle is an okay security solution. We use and deploy some applications and features from Oracle that are better than what others offer. The data in the tool is actually stored in the production part, so it is always kept a secret. I don't think that AI has been integrated into the tool. The AI used by Oracle is not as strong as that used by AWS. I recommend the tool to others, especially banking, finance, and insurance companies where the security needs to be better. There is maintenance for the tool required, but I don't know which company does it for our organization. I rate the tool a ten out of ten.
