Improves database performance, supports AI integration, and accelerates customer-focused innovation
Azure Database for PostgreSQL can be improved in the area of elastic capabilities. One of the things we were actively looking for is the elastic feature, which was made a GA at this Ignite event. I am really happy that finally in Azure, we have a product which we can use for elastic clusters. If you are bound with a single server, then you have a vertical limit. Now you do not have any limits. As long as your use case grows, we can grow. The only thing I would maybe be thinking about is we should also allow customers to pick different node sizes for every node inside the elastic eventually. Some nodes do not need that big capacity. So that may be a nice-to-have feature, though it is not a must-have at this point.

I believe that the documentation should be increased, and features such as vector AI search and other AI capabilities need improvement for Couchbase Capella. I would say that there is a need for developer experience enhancements, including a simpler user interface, better debugging, SQL++ guidance, and more visibility into granular workload-level costs while reporting. Couchbase Capella can improve the accuracy and reliability of its AI output. Though it is not guaranteed that the large language model answer will be correct, improvements can be made by grounding the large language models and controlling parameters such as temperature to provide better results.

Quotes from Members

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

Pros

"What I appreciate most about Azure Database for PostgreSQL is not one particular feature; I think it is the use case and the facility to have a single pane of glass for managing what is on the edge, what is on the cloud, especially now with Azure Local as well."
"Automatic patching and backups have saved us time; anything automatic is a blessing—it allows us to be hands-off, and the reliability has been very good with it."
"The effective integration of Postgres with Microsoft products, especially with the inclusion of AI features in Azure AI, is significant for our applications."
"Compared to my previous expenses for maintaining an on-premise PostgreSQL database, Azure Database for PostgreSQL is far easier, far simpler, and far cheaper in my opinion."
"The performance of our RAG application is very good. We have 96% satisfaction."
"With PostgreSQL, the documentation is perfect, and using it on Microsoft is easy because there is documentation for Microsoft PostgreSQL, which I find easy to follow."
"Azure Database for PostgreSQL has positively impacted my organization through collaboration by allowing me to generate a report within a second and send the MIS for an employee or a team, making it very easy to display for business purposes."
"Postgres has helped us innovate and stay competitive."
"For specifics, I can say that performance is 80% faster, with a four-fold increase in throughput requests and application availability uptime rising from 99.9% to 99.9999%, and the application can now handle three times more traffic."
"The initial setup was straightforward."
"The way the nodes are managed is interesting."
 

Cons

"Support can certainly get better."
"We would love to definitely see scalability. We would love to see it grow as more people use it and it can handle the data and maybe tell us some optimizations by reporting on what we have."
"While the flexibility of the server for financial reasons is understandable, better switching between primary and backup would make transitions smoother."
"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."
"Azure Database for PostgreSQL has not really helped reduce infrastructure costs at my company."
"Coming from a traditional Oracle Exadata setup, all queries will run faster because Oracle has that optimization layer in between which optimizes it for you, which is why you pay a lot of money for that. When you come to Azure Database for PostgreSQL, that layer is gone."
"The critical service is the Azure OpenAI service. It would help to make it simpler and easier to integrate with that or cognitive services."
"However, when I start planning for production where the service will be up for two or three years, I prefer to pay upfront, as the pay-as-you-go model becomes expensive for production use."
"The product could be improved by including a log section for tracking activities, enhancing database integration, and providing more transparency regarding pricing and monitoring activities."
"I believe that the documentation should be increased, and features such as vector AI search and other AI capabilities need improvement for Couchbase Capella."
"Rebalancing could be improved."
 

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."
"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 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."
