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.

Efficient data storage with reliable and easy management
We are working on monitoring software that involves making a lot of measurements with sensors. We store all the data in Firebird, which is why we use It primarily for data storage It's difficult to describe how it has improved our organization because we have been using Firebird for a very long…

Quotes from Members

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

Pros

"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."
"The flexibility that we have with the JSONB functionality allowed us to get data into the system, build the POC, get it in front of people, and then as we find needs for things to be more normally normalized, we can go back and make those changes."
"It is easy to use and optimize. It is very easy for us to understand how a chopped chunk can be translated into embedding."
"The most valuable features of Azure Database for PostgreSQL are its networking capabilities, which allow for integration with other Azure services."
"If a client is looking to check these boxes—performance, speed, reliability, and resiliency in general—knowing that it will satisfy application needs not just today but in the future, it is definitely a choice."
"The operational efficiency of Azure Database for PostgreSQL is good."
"The effective integration of Postgres with Microsoft products, especially with the inclusion of AI features in Azure AI, is significant for our applications."
"Overall, we are satisfied with Microsoft solutions and recommend them."
"I like that we don't have to pay external fees to migrate this data. So, we are looking to relocate from Postgres or EDB."
"The product was easy to use."
"The documentation is very well written."
"The solution is very useful for stock management."
"We are happy with the event capabilities of Firebird SQL database. We can raise events from it and display them in our application."
"The solution has worked perfectly; I've never run into issues or had to reach out to technical support for troubleshooting."
"It helps us in detecting all kinds of problems in the code, such as bad quality, unclear code, or any violation in the code or best practices."
"Robustness is the absolutely main feature."
 

Cons

"They can offer more RAG extensions. Currently, it only has the vector search."
"In the future, I would like to see anomaly detection."
"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."
"Occasionally, we experience throughput issues due to bandwidth limitations of client setups with Azure, which have limited connections, but as far as the service itself goes, it has been rock solid."
"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."
"Azure Database for PostgreSQL can be improved in ways I'm very curious to explore with Horizon."
"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."
"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 security of the users could improve in Firebird SQL."
"The solution could improve by providing partitioning and encryption. It is not at the higher level of database solution but it could be with some upgrades."
"I'd rate the solution five or six out of ten for the possibilities it has currently."
"It would be good to have more automation and integration with the tools from other vendors."
"Database sharing is a capability that Firebird SQL lacks."
"The main feature I expect is to be able to work with different databases at the same time because that's a wishlist item for me."
"They need to be more reactive and fast. Sometimes, they take too long to resolve some tickets."
"In the next release, it should support JSON, XML, and replication with third-party tools."
 

Pricing and Cost Advice

"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."
"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."
"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."
"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."
"It is okay."
"It's open-source and free."
"We are using the free solution, so there is no cost involved."
"The most valuable feature of the solution is that it is freely available."
"It is a public domain system as every customer can install it on their system without paying any license fee."
"I was using the free version of Firebird SQL."
"There is no licensing cost for this solution, as it is open-source."
"Firebird SQL is an open-source solution, which means it is a free product."
