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.
Shrikant Navelkar - PeerSpot reviewer
Have achieved excellent performance and seamless integration with effective cost control in cloud solutions
When customers are migrating from Oracle Exadata Express Cloud Service and need to remove some of their test and development environment, what happens in normal virtualization is that they can just switch it off, but in ExaCS, they need to terminate the entire thing. Most of the customers are not aware of this, so they keep spending money even if they want to shut down their UAT environment or development environment, so Oracle needs to make it simpler in terms of reducing the bill on ExaCS when customers want to shut down certain environments. Today, you have to terminate the entire VM, and only then your billing will stop. The only functionality I would expect from Oracle Exadata Express Cloud Service is that if Oracle is able to support Oracle MySQL Enterprise also on Exadata, that will solve a lot of problems.

Quotes from Members

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

Pros

"In terms of integration, we already have SharePoint online, and we're starting to explore PowerApps and PowerFlow. It's all seamless. The ease of integrating SQL and licensing purposes plays a significant role, making it a comfortable choice for the organization."
"The operational efficiency of Azure Database for PostgreSQL is good."
"I rate Azure Database for PostgreSQL 10 out of 10."
"We use PostgreSQL to speed up application development. Our applications are ready sooner because we don't need to depend on other database teams."
"Backups are easy, resizing is quick, and the query analyzers help me find out what's happening in each of the queries."
"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."
"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."
"The most valuable features of Azure Database for PostgreSQL are its networking capabilities, which allow for integration with other Azure services."
"I like that Oracle Exadata Express Cloud Service is easier to use and is a cost-saving solution because you won't need to hire people to run and maintain it."
"The performance of the tool is valuable."
"I would rate Oracle Exadata Express Cloud Service ten out of ten for its overall solution."
"It is a scalable product."
"I highly recommend Oracle Exadata Express Cloud Service as a very good solution if you can afford it."
"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."
"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."
"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."
 

Cons

"They can offer more RAG extensions. Currently, it only has the vector search. It does not presently support knowledge graph functionalities as Neo4j does. It also does not offer some tools to improve indexing the way other vector databases offer."
"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)."
"The critical service is the Azure OpenAI service. It would help to make it simpler and easier to integrate with that or cognitive services."
"There is a stability issue where, if the database usage peaks quickly, it may crash and require intervention to restore functionality. It does not auto-heal or self-heal in such situations."
"The critical service is the Azure OpenAI service. It would help to make it simpler and easier to integrate with that or cognitive services."
"In the future, I would like to see anomaly detection."
"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."
"There is a stability issue where, if the database usage peaks quickly, it may crash and require intervention to restore functionality. It does not auto-heal or self-heal in such situations."
"The product's installation process needs improvement. It could be more accessible."
"The support must be faster."
"The solution's pricing could be improved."
"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."
"Oracle's support could be better."
"We use artificial intelligence for deep learning, and it would be a huge benefit to implement this in Oracle Exadata."
"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."
 

Pricing and Cost Advice

"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."
"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 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."
