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.

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

"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."
"Azure Database for PostgreSQL has impacted our ability to innovate and stay competitive in our industry by helping our developers understand what features need to be used so they can deliver the customer use case much faster, get the value out faster, and once you get the value out faster, you are ahead of the competition."
"The most valuable features of Azure Database for PostgreSQL are its networking capabilities, which allow for integration with other Azure services."
"We use PostgreSQL to speed up application development. Our applications are ready sooner because we don't need to depend on other database teams."
"Azure Database for PostgreSQL is hugely discounted and cost-effective compared to the previous expenses for maintaining an on-premises PostgreSQL database."
"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 performance of our RAG application is very good. We have 96% satisfaction."
"Firebird SQL is an open-source solution."
"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."
"The reliability and ease of management are very valuable."
"Firebird SQL is an open-source solution and can run on most operating systems, such as Linux, Unix, and Windows."
"We are satisfied with Firebird SQL, and we will keep on using it."
"The documentation is very well written."
"I can deploy it on Linux, Mac OS, and Windows — it's very easy."
 

Cons

"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."
"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."
"Currently, most databases will try to use all the CPUs available and use all the memories available. We try to give all the databases one hundred percent of the hardware capacity, but sometimes because the OS layer itself will need some resources."
"Support at best is a five out of ten."
"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."
"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 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."
"Azure Database for PostgreSQL has not helped reduce infrastructure costs for me or my clients."
"Firebird SQL's performance has slowed since Firebird SQL 3 or 3.5 versions, where they developed over-the-wire encryption."
"Database sharing is a capability that Firebird SQL lacks."
"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."
"There aren't a lot of people using this solution — it's not very popular in the marketplace."
"It would be nice to have a graphical user interface to handle the product."
 

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."
"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."
"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 okay."
"There is no licensing cost for this solution, as it is open-source."
"It is a public domain system as every customer can install it on their system without paying any license fee."
"The tool is open source."
"There is a yearly maintenance fee for the use of the solution."
"I was using the free version of Firebird SQL."
