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.

Multi-node architecture and it is good from a security point of view
I would rate the stability a seven out of ten. Most of the issues we faced during troubleshooting were due to specific bugs in the environment, and the only solution was to upgrade the database environment or services. But it is not easy to upgrade the database level when third-party applications are involved, as they are not always comfortable with upgrading. There should be some cumulative solution provided by IBM for their customers, just like other vendors. Upgrading to a certain version doesn't always resolve the issue. It might get resolved at the database level, but what about the other applications integrated with that database that are only compatible with older versions?

Quotes from Members

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

Pros

"I rate Azure Database for PostgreSQL 10 out of 10."
"A native cloud approach actually has more advantage because it is easy to deploy, faster to deploy, and easy to recover and roll back."
"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."
"The pay-as-you-go pricing model is one feature I truly appreciate."
"The performance of our RAG application is very good. We have 96% satisfaction."
"Azure Database for PostgreSQL has positively impacted our organization by helping us improve reliability and simplify database operations."
"It is easy to use and optimize. It is very easy for us to understand how a chopped chunk can be translated into embedding."
"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 reliability is the most valuable feature. It is also user-friendly."
"Multiple business departments rely on reports and predictive analysis to make decisions for future business based on their data warehouse and Db2 network analytics tool. It helps our business department make decisions."
 

Cons

"Microsoft support has become less reliable due to AI responses, but with Azure Migration Assessment, we can plan migrations easily."
"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."
"Azure Database for PostgreSQL can be improved in ways I'm very curious to explore with Horizon."
"For development purposes, it is fine, but on production, you need to have a check on the cost of it."
"The critical service is the Azure OpenAI service. It would help to make it simpler and easier to integrate with that or cognitive services."
"I believe Azure Database for PostgreSQL can be improved by allowing features that are only enabled or configured during creation to be configurable without redeploying the entire database, a process which can impact our customers if it involves an application outage."
"I would add that from my perspective, Microsoft technical support isn't great; we have tickets sitting in the bucket."
"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."
"I would give their support a ten if they had more tutorials available."
"Nobody is going to like the price."
"In other environments like Oracle or Teradata, they provide their own solutions for troubleshooting issues. They provide built-in AI services or autonomous databases, which I don't see in the Db2 environment."
 

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."
"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."
