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.

Enhances performance without fine tuning databases
They need to simplify the monitoring of the Exadata services. They have to make it more simple for the users to operate or manage. And one more thing, I would expect that other databases of Oracle, like MySQL Enterprise Edition, if technologically, Oracle makes some advancement and allows MySQL Enterprise Edition to run on Exadata, I think that will improve their market share exponentially. Today, on Exadata, you run Oracle databases, which is given. Apart from that, Oracle also has Oracle MySQL database, open source. If that open-source database also runs on Exadata, I think that will help a lot of customers. In the next release, Oracle can provide a script-level solution to migrate or consolidate cross-platform databases from Unix platform to Oracle Exadata on Linux platform; if they can provide some migration tools, I think that will help.

Quotes from Members

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

Pros

"Backups are easy, resizing is quick, and the query analyzers help me find out what's happening in each of the queries."
"Overall, Azure Database for PostgreSQL has been good for us."
"The operational efficiency of Azure Database for PostgreSQL is good."
"Our organization's database uptime has improved after implementing Azure Database for PostgreSQL, particularly with the flexible server's redundant configuration capabilities, which allow for failovers and read-only configurations."
"The performance of our RAG application is very good. We have 96% satisfaction."
"The most valuable features of Azure Database for PostgreSQL are its networking capabilities, which allow for integration with other Azure services."
"Backups are easy, resizing is quick, and the query analyzers help me find out what's happening in each of the queries."
"PostgresSQL is acknowledged as an incredibly powerful industry leader. We've built critical pieces of national infrastructure in the UK that rely on Postgres. A version of Postgres on Azure that's easy to adopt enables us to innovate. The addition of AI extensions is even more exciting. It's a significant opportunity for us."
"Having the prediction happen in the modular format allows you to start with a lower version of Exadata and then you can keep on upgrading it as per your requirement."
"The solution is very stable and offers great performance."
"The performance of the tool is valuable."
"In the cloud, Exadata is more scalable. The on-prem version was limited. It wasn't that scalable because it only came in a quarter rack, half rack, and full rack. In the cloud, it scales to what you need."
"I highly recommend Oracle Exadata Express Cloud Service as a very good solution if you can afford it."
"It is a scalable product."
"I would rate Oracle Exadata Express Cloud Service ten out of ten for its overall solution."
"One of the most valuable parts of the solution is the high availability within the system and the performance enhancement without making any changes or fine-tuning the databases."
 

Cons

"They can offer more RAG extensions. Currently, it only has the vector search."
"Support at best is a five out of ten."
"There aren't any notable areas for improvement that I could see. PostgreSQL was self-sufficient with no need for additional database knowledge to maintain it."
"Performance is one area that has constraints for our customers. I believe there could be improvements in the mirroring part and Change Data Capture (CDC)."
"Support can certainly get better."
"While the flexibility of the server for financial reasons is understandable, better switching between primary and backup would make transitions smoother."
"The critical service is the Azure OpenAI service. It would help to make it simpler and easier to integrate with that or cognitive services."
"Perhaps a minor improvement could be made in simplifying user additions, allowing for an easier process rather than scripting it out. However, scripting is not a significant issue."
"The solution's pricing could be improved."
"The only downside is the difficulty in monitoring, and that's why I would like to implement MySQL database."
"I feel there is a need for better integration with Google Maps and Google Earth. This is crucial for me in the geographical facilities of the environment."
"We use artificial intelligence for deep learning, and it would be a huge benefit to implement this in Oracle Exadata."
"The support must be faster."
"Oracle's support could be better."
"Scaling Oracle Exadata Express Cloud Service can be done, but the process is a little tedious, which could be an area for improvement in the solution."
"The customer's default choice is the on-premise version of this solution. Only when Oracle or the partners like us, can explain to customers the cloud value proposition, and if the compliance authorities allow, they can look into this cloud solution. It will take some time for Oracle to change its perception of customers' de-facto standards. Exadata used to be treated as a black box, which is not the case now. The customer is aware of what is happening inside, how the configurations have been made, and what patching has been applied. Oracle needs to market the cloud version better."
 

Pricing and Cost Advice

"There aren't any notable areas for improvement that I could see. PostgreSQL was self-sufficient with no need for additional database knowledge to maintain it."
"The pricing experience is positive. Azure Database for PostgreSQL reduces the need for hardware investments, and 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 pricing model plays a critical role in managing database-related costs and resource allocation. We build using Infrastructure as Code (IAC) and maintain a focus on FinOps to control Azure service costs. Some clients are pushy on price. It's critical to automate it, so we're just using it when appropriate and switching it off in certain scenarios."
"We do not pay for a full-year subscription because our usage is still at the beginning phase and not much. The pay-as-you-go model works well for us."
"The tool is not cheap, but it is not really expensive."
"The price of this solution is very comparative to others on the market. There is no direct comparison between this solution and with something else because I do not see any other similar product."
"I think Oracle pricing is usually above average market price."
