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.

Vector search has improved e‑commerce relevance but setup and learning curve still need work
Vespa definitely had its own set of challenges. It was really hard to get into initially, especially when I started implementing it in 2024 along with one junior employee, and the lack of documentation made it difficult. I aimed for an implementation with ColBERT, a sparse embedding mechanism, which I believed would fit well for e-commerce. We went through iterations during A/B testing because the initial set did not work as expected, which extended the process to about one and a half years. Vespa has a considerable learning curve, making it challenging for most people to get into, and it is also expensive, which can deter startups or those with smaller budgets from using it. Community support was decent, and we turned to it for clarifications. However, substantial improvements in documentation are necessary, especially more examples for handling DSL effectively. Having a runtime testing feature would greatly facilitate quick iterations.

Quotes from Members

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

Pros

"Postgres has helped us innovate and stay competitive."
"It is easy to use and optimize. It is very easy for us to understand how a chopped chunk can be translated into embedding."
"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 influenced my application development process by enabling me to take some of what we used to do on-premises, with PostgreSQL hosted in virtual machines, and transition that process into a SaaS solution."
"Overall, Azure Database for PostgreSQL has been good for us."
"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."
"Backups are easy, resizing is quick, and the query analyzers help me find out what's happening in each of the queries."
"The benefits we have realized as a company from using Azure Database for PostgreSQL on Azure make the life of our customers and our solution easier."
"Vespa is very good and it improves our product, and we got more clients."
"While conducting A/B testing, Vespa seemed to be performing slightly better than Elasticsearch, especially in search relevancy within live production systems, and its performance was decent."
"The best feature to me is the LTR feature, the ranking feature to be specific."
 

Cons

"They can offer more RAG extensions. Currently, it only has the vector search."
"Azure Database for PostgreSQL has not really helped reduce infrastructure costs at my company."
"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."
"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."
"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."
"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."
"Performance is one area that has constraints for our customers. I believe there could be improvements in the mirroring part and Change Data Capture (CDC)."
"Azure Database for PostgreSQL has not helped reduce infrastructure costs for me or my clients."
"We want Vespa to implement some UI features so that we can visualize how our data goes and what embeddings it stores."
"The integration is actually a pain."
"Vespa has a considerable learning curve, making it challenging for most people to get into, and it is also expensive, which can deter startups or those with smaller budgets from using it."
 

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."
"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."
"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."
