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.

Offers good performance to users

The tool lacks to offer AI features. In the future, I would like the product to offer AI features to users. Nowadays, we are creating small acronyms for our SQL Server. We put some templates. If I just put your name and stop it, the entire cloud can be explored, but such features are not there in Google Cloud Spanner. As a layman rather than a developer, if I create a tool or a procedure. If I write a procedure and then when you describe a procedure, a dummy procedure will be written for you, and it will be available for you as a template in SQL Server, but such kind features are not there in Google Cloud Spanner.

Quotes from Members

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

Pros

"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 performance of our RAG application is very good. We have 96% satisfaction."

"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."

"Automatic patching and backups have a huge impact on my database management strategy—we have an operations team of two people and do not have time to handle database maintenance manually, so we chose platform-as-a-service for this reason."

"The most valuable features of Azure Database for PostgreSQL for us are reliability, performance, and cost, making it a good cost-benefit for us."

"I rate Azure Database for PostgreSQL 10 out of 10."

"We transact 128 trillion data per month using Azure Database for PostgreSQL, which helps us to be more successful on every transaction that the customer is requesting from us."

"Postgres has helped us innovate and stay competitive."

Cons

"We had to move to a CSP. This has been a significant challenge. We experienced trouble with our CSP and had to change CSPs because we could not get the level of support we needed from them."

"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."

"Microsoft support for Azure Database for PostgreSQL rates about four out of ten based on my experience. You always get the same questions with Microsoft support, and it's not really straightforward."

"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."

"Support at best is a five out of ten."

"Support can certainly get better."

"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."

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 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 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."

"Google Cloud Spanner is an expensive solution."

"The solution is expensive."

"Price-wise, I heard that Google Cloud Spanner is on the higher side."

"It is expensive."
