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

"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."
"A native cloud approach actually has more advantage because it is easy to deploy, faster to deploy, and easy to recover and roll back."
"The operational efficiency of Azure Database for PostgreSQL is good."
"Azure Database for PostgreSQL helps to speed up processes and really does impact the time to market for our applications."
"Azure Database has become easier to use over time."
"The performance of our RAG application is very good. We have 96% satisfaction."
"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."
"Overall, Azure Database for PostgreSQL has been good for us."
"I appreciate the fact that, once the database is embedded, it doesn't need to be administered, and removes the requirement for a specific server."
"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."
"The solution is very useful for stock management."
"The most valuable feature of Firebird SQL is the creation of databases."
"I can deploy it on Linux, Mac OS, and Windows — it's very easy."
"The solution has worked perfectly; I've never run into issues or had to reach out to technical support for troubleshooting."
"I find the ease of deployment to be the most valuable aspect of this solution."
"We are satisfied with Firebird SQL, and we will keep on using it."
 

Cons

"While the flexibility of the server for financial reasons is understandable, better switching between primary and backup would make transitions smoother."
"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."
"Azure Database for PostgreSQL can be improved in ways I'm very curious to explore with Horizon."
"I rate it a seven because it sometimes takes a while to receive that first response from them, which may depend on the case."
"My impressions of the latency and availability of Azure Database for PostgreSQL is that it is a concern that arises post-migration."
"I do not know how Azure Database for PostgreSQL can be improved or what additional features I would prefer to see. There may be some pain points that would be valuable to fix."
"Microsoft support has become less reliable due to AI responses, but with Azure Migration Assessment, we can plan migrations easily."
"Technical support and performance could be better. We have some problems with this solution, but we don't know if the problem is with the database or the configuration. For example, sometimes, the users can't access the database."
"On large databases, we have some difficulties."
"Database sharing is a capability that Firebird SQL lacks."
"It is not easy to integrate the tool with Visual Studio."
"The security of the users could improve in Firebird SQL."
"We would like to improve the management of very large databases."
"I don't think the solution is very scalable, because the scalability of the performance when using more than one process is not very good."
"In the next release, it should support JSON, XML, and replication with third-party tools."
 

Pricing and Cost Advice

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